Top match
Claude is a strong fit for you because research and long-form writing are exactly what it does best. You can start on the free tier, though it has a lower daily message cap than the paid plans, which matters most when you're working with long documents. If you regularly analyze lengthy documents or keep running into that message limit, upgrading is worth considering, and note that Claude Code requires a paid plan as well.
