Frequently asked questions
What is the best AI data analysis tool?
Julius for personal CSVs. ChatGPT or Claude for ad-hoc exploration. ThoughtSpot Sage for enterprise analytics.
Can AI really do my analysis?
Yes for 70-80% of standard analyst tasks: data wrangling, basic stats, dashboards. The last 20% (causal inference, complex joins, bespoke methods) still needs human analysts.
Is this OK for sensitive data?
Not on free-tier consumer tools. Use enterprise offerings (ThoughtSpot, Hex enterprise, Akkio enterprise) with data-handling addendums. Or run models on-prem.
What about Tableau + AI / Power BI + AI?
Tableau GPT and Power BI Copilot both added AI Q&A in 2025-2026. Quality is improving fast. They are catching up to ChatGPT/Claude but still 6-12 months behind.
