A different kind of search
Retrieval that points back to what was actually there.
Document Processor helps you find relevant passages, pages, and moments. It keeps the original source, timestamps, and review trail attached so the result remains something you can inspect—not an answer you have to take on faith.
How it works
From messy files to dependable evidence.
One desktop workflow for the material that normally gets scattered across folders, apps, and recordings.
Process locally
OCR, transcription, and semantic indexing run on your device using the processing profile you choose.
Search naturally
Combine exact terms with meaning-based retrieval, with optional refinement when accuracy matters most.
Review the source
Open the original context, verify the passage, and keep accepted evidence immutable and traceable.
Built for real collections
Useful across the formats you already have.
Start with the files on your computer. Add structure only where it helps you find and verify the underlying material.
TXT
Documents & PDFs
Plain text, Markdown, HTML, and PDF content stay connected to the source document.
OCR
Scans & images
Extract text from visual documents while retaining page context and normalized evidence anchors.
AUDIO
Recordings
Import WAV, MP3, and FLAC files with timestamped transcription evidence and original audio preserved.
EXP
Portable library
Export your accepted library and restore it later without depending on a remote account or service.
Your data stays yours
Privacy is an architecture decision, not a settings page.
Document Processor is designed around local processing, user-controlled storage, and evidence you can inspect. There is no remote query parser, no recurring inference service, and no requirement to upload your library to search it.

Processing is performed locally on the desktop.
Export when you choose
Your accepted library is not trapped in the app.
Evidence over invention
Search surfaces source material instead of generating a replacement answer.
Availability
Windows first. macOS follows after validation.
The Windows release is being prepared for packaging and store delivery. macOS implementation is in progress, with final testing intentionally scheduled after the rest of the release path is in place.
