◎Semantic search
- Concept matching (vector)
- Hybrid mode — keyword + meaning
- Reranking for precision
Colpan indexes hundreds of thousands of files on your machine — contracts, court filings, scans, mail archives — and finds the one you need before you finish typing. It reads formats other tools can't, understands how words change shape, and masks personal data to GDPR grade before any AI sees a single line.
Morphology-aware matching catches every inflected form of a word; a full query language — fields, dates, regex — drills exactly where you point. Results and previews arrive in milliseconds, even on archives of hundreds of thousands of files.
100+ formats including Office, ODF, RTF and regional court formats other tools skip; looks inside ZIP/RAR archives; scanned PDFs become searchable text through built-in OCR.
Everything runs locally — documents never leave your machine. The PII layer masks names, IDs and IBANs to GDPR grade before any AI sees a line, with an encrypted vault and permanent redaction on higher plans.
Point Colpan at your archive and the pipeline takes over — every step runs on your machine.
100+ formats — PDF, Office, ODF, RTF, e-mail exports, code, and archives (it reads inside ZIP/RAR too). Hundreds of thousands of files indexed at full speed, kept fresh by live file watching.
Scanned PDFs and images are triaged and turned into searchable text automatically — your paper archive becomes queryable like everything else.
Heavy PDFs and Office documents open in milliseconds with your search hits highlighted — no Office, no waiting, straight to the matching page.
Structural + NER + LLM detection, an encrypted vault, permanent redaction and clean exports — personal data is under control before any AI ever sees it.
Curate the documents that matter into a local vector database — semantic and hybrid search over concepts, not just keywords, with reranking on top.
Chat answers are grounded in your own corpus, with evidence chips pointing back to the exact documents — work on your files, don't just talk about them.
Colpan is more than an app: it is a programmable document layer. An agent like Claude Code can scan, search and organize your archive through the colpan command — with the PII guard on for every call.
Humans use the interface, agents use the terminal. Both see the same index and the same privacy rules.
The engine does the work. And when finding isn't enough — ask: the AI runs on the same index, on your terms.
Tiers scale what the engine handles — how much you index, OCR and protect. AI is included as monthly credit; BYOK and local models are free on every plan.

The engine. Each plan licenses the full desktop app and scales its capacity — how many documents you index, how many pages you OCR each month, which PII layers you get, and how many devices share it. A monthly AI credit is included on top; AI is the fuel, not the product.
Nothing stops — search, preview, OCR and everything local keep working at full speed. Chat resumes at your next monthly renewal, or immediately if you switch to your own API key (BYOK) or a local model. Add-on credit packs are coming soon.
Your documents stay on your machine. Only when you chat does the relevant text go to a cloud model — and it passes through the PII guard first. Critical personal data is masked or blocked.
Yes — each plan supports as many devices as its shareable seats (Solo 1, Pro 3, Max 5). Every device draws on the same AI credit.
Managed: no keys, no separate billing — Colpan credit. BYOK: your own OpenRouter/OpenAI key, straight to the provider — Colpan never sits in between.
Yes, anytime — subscriptions are monthly with no lock-in. See our refund policy for details.
Set up Colpan in minutes — your archive will feel searchable for the first time.
