The short answer

Use Better Analyst if you want an AI analyst that works across uploaded files and connected sources such as Google Analytics, BigQuery, Snowflake and Postgres, and turns answers into dashboards and scheduled reports. Use ChatGPT or Claude for one-off analysis of a file you upload. Use Copilot in Excel or Gemini in Sheets if your data already lives in that spreadsheet, and Hex if you're a data team that wants AI inside SQL and Python notebooks.

What an AI data analyst actually does

Every tool in this guide follows the same loop. You ask a question in plain English. The AI writes code, usually Python or SQL, and runs it against your data. Then it returns a table, a chart or a written answer. They differ in four places:

  • Where the data comes from. A file you upload, the spreadsheet you have open, or a live connection to a database or app.
  • Whether you can check the work. Some show the code behind every answer; some only show the result.
  • What happens after the answer. A chat reply you copy elsewhere, or a dashboard, a scheduled report and an alert that keep running.
  • Who it's built for. Business users who never want to see code, or analysts who want AI inside their own notebook.

The 6 best AI data analyst tools

02

ChatGPT

The most familiar option: upload a file, ask questions, and get charts and tables from Python that ChatGPT writes and runs.

ChatGPT is a sensible first stop for a single file and a single question. OpenAI's help centre puts the per-file limit at 512MB, with spreadsheets capped at about 50MB depending on row size. Where it falls short is repetition: next month's version of the same analysis starts again from a fresh upload.

Best for
One-off analysis of a CSV or Excel file
Pricing
Free plan; paid plans add higher usage limits

What we like

  • Runs Python on uploaded files and shows the code
  • Handles many file types; spreadsheets up to about 50MB, other files up to 512MB
  • Good at explaining results and drafting the write-up

Watch out for

  • Each chat starts from the files you upload, so recurring reports mean re-uploading
  • No built-in dashboards or scheduled reports on your data
  • Large spreadsheets hit the roughly 50MB cap

03

Claude

Strong at multi-step analysis that ends in a file: it runs Python and can return an Excel workbook with working formulas and charts.

Claude suits analysis where the deliverable is a file someone else will open. Anthropic's help centre says it can build Excel files with working formulas and charts, and produce charts as images. Enterprise organisations get network access turned off by default, which some IT teams will want.

Best for
Analysis you want to hand over as a spreadsheet or report
Pricing
Code execution and file creation on every plan, including Free

What we like

  • Runs Python on uploaded CSV, TSV and other data files
  • Creates .xlsx files with working formulas, formatting and charts
  • Available on Free, Pro, Max, Team and Enterprise plans

Watch out for

  • 30MB per file for uploads and downloads
  • Like ChatGPT, it works on files you upload rather than live, scheduled data
Claude file creation help
04

Copilot in Excel

The natural choice if your data already sits in an Excel workbook and your company pays for Microsoft 365 Copilot.

If your team lives in Excel, Copilot meets you there. Microsoft positions plain Copilot for quick answers, Agent Mode for multi-step work it plans and checks in the workbook, and its separate Analyst agent for heavier Python analysis across files. Check with your admin which of these your tenant has turned on.

Best for
Excel users with a Microsoft 365 Copilot license
Pricing
Needs an eligible Microsoft 365 Copilot plan; see Microsoft's pricing

What we like

  • Answers questions about tables in your workbook using Python-based analysis, and lets you expand the answer to see the code
  • Advanced analysis mode runs Python on a new sheet and can insert it as a refreshable Python cell
  • Agent Mode plans and carries out multi-step work with tables, PivotTables, charts and formulas

Watch out for

  • Works on structured tables in the workbook; Microsoft says unstructured data isn't supported
  • Feature availability depends on your license and your admin's settings

05

Gemini in Google Sheets

Quick summaries, formulas and charts inside a Google Sheet, for teams already on an eligible Workspace plan.

Gemini is the low-effort option for Sheets users: no upload, no new tool. It's strongest at formulas and quick summaries of data already in the sheet. Once questions span a database, an analytics account and a spreadsheet, you'll need a tool that connects to all three.

Best for
Google Workspace teams who keep their data in Sheets
Pricing
Included in eligible Workspace editions (Business Standard and Plus, Enterprise Standard and Plus) and Google AI Pro and Ultra

What we like

  • Works across multiple tables on one tab and writes formulas, such as XLOOKUPs, that join them
  • Finds trends, outliers and summaries in a selected range
  • Builds charts and pivot tables from a request

Watch out for

  • Works inside one spreadsheet, with no database connections
  • Charts are inserted as static images
  • Requires an admin to turn on Gemini smart features
Gemini in Sheets update
06

Hex

A notebook platform for data teams, with an AI agent that writes and runs SQL and Python against your warehouse.

Hex fits a team with analysts who want AI to speed up their own work, not replace the notebook. Business users usually consume the published apps rather than ask the agent directly.

Best for
Analysts and data teams who already write SQL
Pricing
Community free; Professional $36 and Team $75 per editor per month; Enterprise custom

What we like

  • AI agent included on paid plans, working inside SQL and Python notebooks
  • Connects to your warehouse and databases
  • Publish notebooks as apps for the rest of the company

Watch out for

  • Built for people comfortable reading SQL and Python
  • Free Community tier includes only an agent trial and limited credits
  • Priced per editor
Hex pricing

Which one should you pick?

  • You have a file and one question: ChatGPT or Claude. Pick Claude if the result needs to be an Excel file.
  • Your data is already in Excel or Google Sheets: Copilot in Excel or Gemini in Sheets, if your plan includes it.
  • Your data lives in a database, warehouse or business apps, and you don't write SQL: Better Analyst.
  • You need the same analysis every week or month: Better Analyst, for scheduled reports, dashboards and alerts.
  • You have a data team that writes SQL and Python: Hex.

If most of your questions are about website traffic, our guide to AI tools for GA4 reporting goes deeper on that use case.

How to check an AI analyst's answers

The fastest way to lose trust in an AI analyst is to forward a wrong number. A few habits prevent most of it:

  1. Step 1Read the code on the first few answersCheck the date range, filters and joins it used.
  2. Step 2Spot-check one numberCompare one figure against the source system before you share the result.
  3. Step 3Define your metrics onceWrite down how your team calculates revenue, active users or churn, and give the tool that definition.
  4. Step 4Watch the joinsDuplicated rows from a bad join are the most common cause of inflated totals.
  5. Step 5Use read-only accessConnect databases with a read-only user so the AI can't change anything.

Try this prompt

“Compare revenue by customer segment for the last two full quarters. Show the SQL you used, flag any segment that changed by more than 20%, and explain the three biggest movers.”

Frequently asked questions

What is an AI data analyst?
A tool that takes a question in plain English, works out the query or code needed to answer it, runs that against your data and returns the result, usually as a table, chart or written summary. The better ones show the code or SQL they ran so a person can check the logic.
Can AI replace a data analyst?
It can replace a lot of routine analyst work, such as pulling numbers, building recurring reports and answering ad-hoc questions about clean data. It does not replace judgement about which question matters, knowledge of how your business defines its metrics, or checking that the data itself is right. Most teams use AI analysts to answer the routine questions so their analysts, or the founder doing that job, can spend time on the hard ones.
How accurate are AI data analysis tools?
They are only as accurate as the code they write and the data they read. Common errors are a wrong date range, a wrong join between tables, or a metric defined differently from how your team defines it. Prefer tools that show the code or SQL behind each answer, spot-check one number against your source system, and give the tool your business definitions where it supports them.
How do I ask questions of a SQL database without writing queries?
Connect the database to an AI analyst that generates SQL for you, such as Better Analyst, which connects to BigQuery, Snowflake, Databricks, Postgres, MySQL, SQL Server and Redshift, or Hex for data teams working in notebooks. Use a read-only database user, and check the generated SQL on the first few answers.
Is it safe to upload company data to an AI analysis tool?
Check three things on the vendor's security page. Whether your data is used to train models, where it is stored and for how long, and whether database and app connections are read-only. Business plans from most vendors add admin controls such as SSO. If a vendor doesn't publish these answers, ask before uploading anything sensitive.
