For most everyday users, Petal is the better choice because its robust free tier and excellent citation accuracy make it immediately useful for students and researchers, while Humata's restrictive free plan and lack of a mobile app limit its day-to-day value. The single biggest difference is that Petal offers a genuinely usable free experience, whereas Humata's free tier is too limited for real work.

Common questions
Yes, Humata has stronger OCR for scanned documents, so if you work with a lot of image-based PDFs, Humata is the better choice.
Yes, Petal has a mobile app, but it lacks full PDF editing features — you can search and ask questions, but not annotate or edit documents as fully as on desktop.
Petal is much cheaper — its free tier is robust, and paid plans start at $2.55/month, while Humata's paid plans start at $49/month.
No, Humata does not integrate with Zotero or any reference manager. Petal integrates seamlessly with Zotero and Mendeley.
Petal is better for literature reviews because of its excellent multi-document synthesis and citation extraction, plus its integration with reference managers.
Technically yes, but the free tier is very restrictive — you'll quickly hit limits on the number of documents and queries, making it impractical for regular use.
Petal wins for most people thanks to a generous free tier, mobile app, and seamless reference manager integration, while Humata is a niche pick for heavy-duty scanned document analysis at a higher price.
If you're a student, researcher, or anyone who wants a powerful document analysis tool without spending much money, go with Petal — its free tier is genuinely useful and it works on your phone. If you're a professional who needs to analyze scanned technical documents daily and have a budget for it, Humata is a solid choice, but be aware you'll be tied to your computer.
