Top match
You should try Claude because it’s built specifically for deep research and long-form writing, which matches exactly what you’re working on. The free tier works well for occasional use, but if you find yourself hitting the daily message cap or regularly analyzing lengthy documents, upgrading will save you from constant interruptions. Just keep in mind that if you want to use Claude Code, that requires a paid plan as well.
