What is AI for data analysis?

How natural language and agentic AI are changing the way we work with data

Data teams spend most of their time answering the same questions over and over. "Why did revenue drop?" "What caused the spike?" "Show me last quarter's trends."

AI data analysis helps automate this repetitive work.

You just need to type: "Why did revenue drop last quarter?" 

And, after some data analysis, the system will respond with something along the lines of: "Revenue declined 18% due to mobile checkout issues. Conversion dropped 40% specifically on iPhone 14 devices in the Midwest after the September checkout page update."

The AI agent not only gives you the answer in plain English but also generates the SQL, builds visualizations, and surfaces the patterns behind the answer. You can review its work, refine the queries it wrote, or drill deeper into specific segments.

This guide explains how AI data analysis works, what makes it different from traditional approaches, and how to implement it successfully.

What is AI data analysis?

AI data analysis refers to the use of artificial intelligence to provide conversational analytics and automate parts of the data analysis workflow. In many cases, this means that people without formal data science training can get a lot of questions answered if the AI is answering from trusted data models. 

The term means different things to different people, but AI data analysis typically surfaces in three core areas:

  • AI-augmented code-based analysis — AI that helps data scientists and analysts write SQL and Python faster, generating code, debugging errors, and building visualizations alongside the practitioner.

  • Natural language exploration from scratch — Business users typing questions in plain English and getting answers without writing code or waiting for the data team.

  • AI-powered exploration of existing artifacts — AI that helps users go deeper on dashboards and data apps that already exist, asking follow-up questions like "why did this spike?" directly on published analyses.

Most tools only address one of these areas. But the platforms that integrate all three and have them share the same context (semantic models, rules files, endorsed data sources) create something more powerful: a connected system where a business user's question can flow into a notebook for deeper investigation, then get published as an app that stakeholders explore through the same AI interface.

Consider this typical scenario without AI: you notice revenue declined, so you filter by region. Then by product. Then by time period. Each question requires a new query, a new chart, and another round of manual interpretation. The process is iterative but slow, and depends entirely on knowing which questions to ask.

AI-assisted analysis works differently. You ask your question in plain English: "Why did revenue drop last quarter?" The system analyzes the data, identifies anomalies, and surfaces potential root causes. It might discover mobile conversion rates dropped 40% in the Midwest region, specifically on iPhone 14 devices, after a checkout page update. The system shows its reasoning and the SQL it generated, not just a static chart.

AI analytics can handle pattern recognition across millions of rows, provide natural language explanations, and suggest what to explore next. Business users get answers without waiting for the data team to build reports, while data scientists and analysts can review and refine the AI's work when they need more control.

How does AI data analysis work?

AI data analysis systems combine natural language processing, machine learning models, and governance frameworks to automate data analysis workflows. Here's how these components work together.

Natural language processing

Modern AI analytics platforms use transformer-based language models like BERT to process natural language queries. These models read entire questions at once rather than word-by-word, understanding all terms in context simultaneously. This lets the system connect business terms like "midwest region" or "quarterly timeframe" to the actual database schema.

Ensemble machine learning

AI analytics typically relies on ensemble methods like Random Forests for pattern detection. This approach trains multiple decision trees on different data samples. Each tree identifies different signals. One might flag purchase frequency patterns while another detects order value trends. The ensemble approach catches both obvious anomalies and subtle shifts that single models miss.

Governance and guardrails

AI systems need guidance to generate reliable, secure analysis. Governance frameworks define what the AI can access and how it should interpret business concepts. Data access controls ensure the AI respects existing permissions, so a sales analyst sees their region's data while executives access company-wide metrics.

Rules files provide explicit instructions for query patterns and metric calculations. These guardrails prevent the AI from generating technically correct queries that violate business logic or data security policies.

Semantic layers

Semantic layers bridge the gap between business terminology and database schema. They define how the AI calculates metrics like "monthly recurring revenue" or "customer churn rate", and ensure consistent definitions across the organization. In platforms like Hex, you can also add rules files and endorse previous data work to give AI additional context for more accurate analysis.

Model explainability

AI analysis systems use explainability techniques to show the reasoning behind predictions. These techniques identify the factors contributing to overall patterns. When a user asks why a certain customer is flagged as high-risk, explainability techniques can surface declining usage patterns, payment delays, or increased support ticket volume.

What are the best AI data analysis tools for data science?

The analytics market includes several platform categories, each approaching AI integration differently. Understanding these differences matters when choosing tools, since platforms vary significantly in their AI maturity, approach to governance, and target users.

When evaluating platforms, consider how AI fits your workflow. If your stakeholders primarily consume pre-built dashboards, traditional BI tools with AI features work well. If your data scientists and analysts need to build complex analyses that business users can then explore, you need a platform that bridges technical depth and conversational accessibility.

Current AI analytics platforms

Platform

AI approach

Target users

When to choose

Hex

Native AI integrated throughout with conversational interface, notebook agents, and semantic authoring. AI generates SQL and Python that users can inspect and refine.

Data scientists, analysts, and business users working together

You need one workspace where technical teams build analyses and non-technical teams explore them. Your data team wants to maintain control while enabling self-service.

Tableau, Looker

AI features focused on self-serve for business users (natural language queries, automated insights). No AI assistance for code-based analysis or data team workflows.

Business analysts, executives

Your organization already uses these platforms extensively. Most analysis happens through dashboards rather than exploratory work.

Power BI

AI focused on business user self-serve (Copilot for natural language queries, Q&A features). Limited AI support for technical practitioners.

Business analysts in enterprise environments

You're deeply integrated with Microsoft's ecosystem and need Office 365 compatibility.

Databricks

AI layered into most products (notebooks, BI, chat interfaces), though functionality remains isolated across each.

Data scientists, ML engineers

Your primary use case involves training and deploying machine learning models at scale.

Omni, Sigma

AI focused on business user self-serve. Omni offers ChatGPT integration as a bolt-on; Sigma provides natural language queries within spreadsheet-like interfaces. No AI assistance for code-based workflows.

Data analysts and business users comfortable with SQL

You prefer SQL-first workflows, and your team already thinks in queries.

Key differences in AI maturity:

Beyond the table above, here's what to look for when evaluating how deeply AI is integrated into an analytics platform:

  • AI for every user: The best platforms offer AI at every level, from agents in notebooks for data teams, to natural language interfaces for semi-technical explorers, and chats in existing dashboards for business users. Most BI tools only address the latter two, leaving practitioners without AI support for code-based work.

  • Connected vs. siloed: Consider whether the AI work connects across use cases. Can a natural language exploration become a notebook for deeper investigation, then get published as an app others explore conversationally? Bolt-on AI typically creates isolated experiences that don't share context.

  • Governance and observability: Look for platforms that maintain consistent access controls and metric definitions across AI-generated and human-written queries. Equally important is observability — the ability to monitor what's being asked across the org and where the AI needs better context.

  • Extensibility: Data questions come up in the middle of Slack threads and team meetings, not just when someone opens an analytics tool. Platforms that extend AI through Slack integrations or MCP connections let users get answers without breaking their workflow

The platforms that check all these boxes tend to be ones where AI was built into the architecture from the start, not added later as a feature.

What sets Hex apart

Most analytics platforms force you to choose between technical power and accessibility. Hex provides both in one workspace, and supports all three modes of AI data analysis with shared context across each.

Data scientists and analysts write Python and SQL in collaborative notebooks with AI agents built in. They publish these notebooks as interactive apps that product managers explore through point-and-click interfaces. Business users then ask follow-up questions in natural language, generating new queries and visualizations. When they hit limitations or need deeper analysis, they can surface those questions back to the data team for exploration in the same workspace.

Governance stays consistent across all these interfaces. Access controls, semantic definitions, and audit trails work the same way whether someone writes Python, clicks through an app, or asks conversational questions. Define "monthly recurring revenue" once and it means the same thing everywhere. The analysis, the published app, and the conversational exploration exist in one connected environment where work builds on itself rather than getting duplicated.

This eliminates the usual workflow where analysts build in notebooks, then rebuild in BI tools for stakeholders, then handle follow-up questions via Slack, then rebuild again with new requirements. Everything happens in one workspace, and improvements benefit everyone immediately.

Hex supports different AI agents for different needs: the Notebook Agent helps data scientists and analysts build complete analyses, Threads enables conversational self-service for business users, and the semantic authoring workbench helps teams define metrics that AI uses across all interactions. Context Studio gives data teams observability into what questions are being asked across the organization and where the AI needs better context — so they can continuously improve the semantic layer based on real usage patterns.

Hex also extends AI beyond the platform itself. Slack integration lets users ask data questions without switching tools, and MCP connections allow AI agents in other environments to access your Hex workspace.

Real-world applications

Now that you understand how AI data analysis works, let's examine common real-world applications.

Conversational self-serve analytics that reduces backlog

Data teams spend most of their time answering one-off questions rather than doing strategic analysis. A product manager asks about user retention by cohort. You write the query, create charts, share results. Two days later they want the same analysis for a different time range. You update the query. Then someone from marketing asks essentially the same question for their campaigns. You start over and build more dashboards that generate requests for even more dashboards.

With conversational AI, these questions get answered directly by the people asking them. A product manager types "show me 90-day retention by signup cohort for Q3" and gets an analysis backed by consistent metric definitions. The AI generates visualizations, highlights trends, and shows its reasoning. When they have a follow-up like "how does this compare to Q2?" they ask it directly rather than creating another ticket. If they need something beyond what AI can provide, they can flag it for the data team to investigate.

The data team's work shifts. Instead of processing an endless queue of ad hoc requests, they define the semantic layer that powers everyone's questions. They build the metrics, ensure data quality, and focus on complex projects that actually require their expertise. The time spent on "can you pull this for me?" requests drops substantially, freeing up capacity for work that moves business outcomes.

Accelerating analysis from first draft to published output

AI speeds up every step of code-based analysis because the repetitive code-writing that used to take hours now becomes a conversation with an agent that understands the data model.

But it also lowers the bar for who can do this work. A product manager who knows enough SQL to be dangerous can now build a Python-based predictive model with AI assistance. They describe what they want, the Notebook Agent generates the code, and they iterate from there. Work that previously required a data scientist handoff gets done end-to-end by someone closer to the business problem.

When the analysis is ready, it can be published as an interactive app. Business users can then explore the data through filters and visualizations without bumping into code.  Everyone works off of one artifact, and any improvements there automatically flow to the published app. No more exporting to CSV and rebuilding in Tableau. No more separate artifacts drifting out of sync.

Cross-functional collaboration in shared context

Traditional workflows scatter collaboration across tools and contexts. A data scientist discovers something interesting in Jupyter, screenshots it to Slack, and explains findings over video call. An analyst needs to verify the underlying SQL, so they open their own environment and try to recreate the work. Product managers view results in dashboards built separately from the analysis. Everyone works on related problems but never in the same place.

Unified platforms change this dynamic. A data scientist builds models in Python, an analyst refines query logic in SQL, and a product manager can use AI agents to explore product data freely — all in the same workspace, often simultaneously. When someone spots a data quality issue, they flag it directly in the shared context. Fixes happen immediately, and everyone sees updates in real-time.

The collaboration becomes efficient not because of better communication tools, but because everyone works from the same source of truth. No translation between contexts. No "let me share my screen." No waiting for exports and imports. The friction that consumes hours every week just disappears.

Implementation approach

AI analytics adoption works best when starting small and scaling based on demonstrated value. Quick wins that prove the concept matter more than attempting an organization-wide transformation from day one.

Begin with your technical practitioners. Start with data scientists and analysts who will build the foundation. Connect your data warehouse (Snowflake, BigQuery, Redshift) and identify 2-3 analyses that consume disproportionate time relative to their value. Weekly revenue reports, customer cohort analysis, or performance dashboards are common starting points. Build these in the new platform while keeping existing processes running. This parallel approach reduces risk and gives the team time to adapt.

Extend to stakeholders through published apps once core analyses work well. Convert a successful analysis into an interactive application that business users can explore. A sales leader might use a pipeline forecasting app, while product managers explore user behavior through a retention analysis tool. These early applications serve as proof points. When stakeholders get faster access to insights and data teams receive fewer interruptions, the value becomes obvious to everyone.

Establish governance as usage grows to prevent the chaos that often follows self-service expansion. Build out your semantic layer so metric definitions stay consistent across the organization. Implement access controls that reflect your data sensitivity policies. Enable audit trails that track who accessed what and when. This governance foundation matters more as more people interact with data independently. What keeps self-service from becoming shadow IT is having proper guardrails in place.

Scale self-service access deliberately by starting with teams that have clear, recurring analytical needs. Marketing teams analyzing campaign performance, product managers tracking feature adoption, or finance teams monitoring operational metrics are often good candidates. Let adoption spread organically as teams see others finding value rather than mandating usage across the organization immediately.

Evolve the data team's role as the platform becomes central infrastructure. Time previously spent answering repetitive questions shifts to maintaining semantic models, building reusable analytical components, and tackling complex strategic projects. The transition from reactive request processor to proactive platform builder happens gradually as self-service adoption increases.

You prove value with focused wins, establish necessary guardrails before they become urgent, and scale as teams demonstrate readiness. This beats attempting a comprehensive transformation that looks impressive in planning documents but struggles with real-world complexity.

Where AI analytics is headed

The teams adopting AI analytics now are building advantages that compound over time. When getting data answers becomes dramatically faster and easier, the quality of organizational decision-making improves. Product managers stop guessing about user behavior because they can check actual data in moments. Marketing teams test hypotheses with real analysis rather than intuition. Finance teams spot trends early instead of discovering them in retrospective reports.

Data teams benefit most from this shift. The request queue that previously dominated their time shrinks substantially. They spend more time on complex analyses that require genuine expertise and strategic thinking. The work becomes more interesting and impactful, while everyone else gets the independence they've needed.

This transition isn't automatic or painless. Teams need to invest in semantic layers, establish governance, and adapt workflows. The direction is clear, though, and early adopters are demonstrating what's possible when analytical friction drops dramatically.
