MausBot Document Q-and-A - AI Bot for Personal Document Search

Problem: Individuals who accumulate large personal collections of legal and financial documents (mortgage paperwork, tax returns, insurance policies, medical bills, contracts) have no good way to find specific answers inside them. Desktop search is still largely keyword-based, so questions like 'what was my deductible last year' or 'when does my lease renew' require manually opening and reading many PDFs. Notion AI and similar tools expect you to migrate content into their workspace, which is friction and a privacy concern for sensitive personal records.

Named product: MausBot Document Q-and-A. It attaches a MausBot-powered AI agent to a personal document folder so users can ask questions across their own PDFs and files in plain language and get cited answers.

Solution: Point MausBot at a folder. It indexes the documents, builds a retrieval layer, and answers natural-language questions with references back to the source file and page. Because the target documents are legal and financial, the design priority is accurate citation and privacy-respecting handling.

MVP: A desktop or local-first app that (1) watches a chosen folder, (2) indexes PDFs and common file types, (3) exposes a chat box that returns answers with document and page citations. Ship read-only Q-and-A first; skip editing, workflows, and multi-user features.

Revenue: B2C subscription. A free tier limited by number of documents or queries, and a paid tier (likely $8 to $15 per month) for unlimited indexing and larger folders. Comparables in this AI-tooling space such as Gronk (~$10852/mo), Mig (~$4100/mo), and WormGPT (~$2436/mo) are all payment-verified and sit in the low-five-figure monthly range, which sets a realistic early ceiling for a solo or small team.

GTM: Launch via Show HN and Launch HN, where comparable personal-document and search tools (Khoj, Needl, Almanac) have found their initial audiences. Target people actively complaining about desktop search and document overload.

Growth loops: Users who trust it with sensitive documents become referrers within family and small-practice circles. Shareable 'ask your documents' demo moments and template folder setups (tax folder, home folder) create repeatable onboarding content.
