Rabbithole
Works well as a citation-backed alternative to open-ended web rabbit holes, since every answer links back to a source rather than just asserting facts. Three free searches a day is a real constraint for anyone who wants to use it regularly rather than occasionally, which pushes genuine users toward the annual Pro plan fairly quickly.
Pros
- Every answer comes with source citations rather than unsourced claims
- Conversation history is saved and revisitable rather than disposable
- Low annual price of $60/year compared to typical monthly AI subscriptions
Cons
- Free tier's cap of 3 searches a day is restrictive for regular use
- No stated company, founder, or country behind the product
- Web-only, with no mobile app or browser extension
