AcademicGPT
Page-level grounding is the feature that matters here: an answer you can trace back to a specific page is checkable, which is the whole point when the source is a paper you will cite. It is also plainly a small 2023-era project, with no named vendor, no API and an interface that has not moved in a while.
Pros
- Answers are grounded in the uploaded document with page-level evidence
- Free tier of 100 credits before any payment
- Unlimited tier removes the credit ceiling at $20/month
- Role-aware onboarding for students, researchers and industry
Cons
- Single-document focus, no library or cross-paper search
- No company name, address or jurisdiction anywhere on the site
- Stack and Stripe price IDs date to 2023 with little sign of active work
- No API and no export beyond the browser
