What is the best free AI stock analysis tool?
Short answer
For long-term investors, invest-like is the strongest free option: every one of 21,000+ stocks gets a free 0-100 Buffett-Fit Score, and the free plan includes 3 full written analyses per week plus the daily Consensus screen. For charts and raw data, Koyfin's free tier is excellent; for a quick visual summary, Simply Wall St's free tier works.
What matters
Most "free" AI stock tools give you a teaser: a score with the explanation locked. What matters is whether the free plan lets you actually judge a company.
invest-like's free plan keeps the score on every stock (not a handful), shows the six-metric Buffett checklist against the stock's sector, and gives 3 complete analyses with written reasoning every week.

Questions
Is invest-like really free?
Yes. The free plan has no card and no time limit: the Buffett-Fit Score on every stock, the checklist, 3 full analyses per week, watchlist alerts and the Consensus screen. Pro (EUR 15/month, first month EUR 2.99) removes the weekly limit and adds the Boardroom and Ask Buffett.
Can ChatGPT analyse stocks for free?
It can explain concepts, but without a live data connection it may use outdated numbers and it has no fixed method. A dedicated tool computes the score from current data with a published formula.
