Guides for actually running local document Q&A
Every guide is written for a specific situation: the steps to take, the numbers you should see, and what to do when it does not work out. No theory textbooks — just things you can follow today.
Browser and hardware requirements, with real numbers
Which browsers work, what WebGPU changes, a memory estimate you can apply to your own library before importing, the reduced mobile limits, and generation speed without a GPU.
Fix weak retrieval: chunking, phrasing and model tiers
How to diagnose a bad answer, what chunk size and overlap do to recall, which question shapes favour vector search and which favour keyword search, and when a bigger embedding
Scanned PDFs: detect the missing text layer, then fix it
How to tell a scan from a text PDF, why the tool refuses it with PDF_NO_TEXT_LAYER, how to run OCR without shipping pages to a server, and why OCR errors become search errors.
Set up offline document Q&A, once, in fifteen minutes
What gets downloaded on the first visit, what the service worker caches, how to confirm it, and how to test the whole thing in airplane mode.
Prove your documents never leave your browser
A five-minute DevTools check that shows your files stay on your device, the setups that look private but are not, and the cases that still need a human reader.
