5 lessons from building a local AI app that answers questions about your files

An indie developer shares five lessons from months building ScrapeVantageAI Desktop, a Windows app for Q&A over your own PDFs and documents: (1) privacy beats features — keeping files local and sending only the snippets needed was the biggest adoption unlock; (2) showing sources isn't the same as being right — now every sentence is verified against the exact page it cites and flagged when unsupported; (3) admitting gaps is a feature — teach the checker to distinguish "not defined yet" from fabrication; (4) never make users wait for indexing — allow questions over partially-read folders; (5) meetings are where people lose the most information — the top use case. Useful blueprint for anyone building trust-first document AI.
