Pay once. Convert privately, for life.
The only document-to-Markdown tool that never uploads your files — and tells you if the output will fit your model. Every conversion and the full AI-Ready Pack are free forever. Pro is a single £19 for the workflow around it. No subscription.
Everything you need to convert and prep documents for AI — all in your browser.
- Every format, unlimited files, no size cap
- The entire AI-Ready Pack — token counts, context verdict, chunking
- JSONL export with heading paths & page numbers
- Local OCR, no page limit
- Clean-up engine (headers, footers, page numbers)
- Offline PWA — works with the Wi-Fi off
- 25 results saved locally
Your files never leave your browser — not even to buy this.
- Everything in Free, plus:
- Local MCP server + CLI (npx markprep) for Claude Code
- Watch folders — drop a file in, get Markdown out
- Saved conversion profiles per project
- Enhanced local OCR models & 40+ languages
- Bring-your-own-key OCR for hard scans
- Encrypted sync + unlimited library
- Email support
Everyone else rents. You own it.
Others bill every month, forever, and upload your documents to do it. You pay once, and nothing leaves your browser. Re-verify competitor pricing before relying on this — it changes often.
Frequently asked questions
Is it really a one-time payment?+
Yes. £19 once, and Pro is yours for life — no subscription, no renewals, nothing to cancel. It fits a tool that runs on your machine: we have almost no per-use cost, so we don't need to bill you every month.
Why pay if conversion is free?+
You shouldn't, unless you want the local MCP server, watch folders, saved profiles or encrypted sync. Every conversion, the token count and the chunk plan are always free and unlimited. Pro sells the workflow around conversion, not access to it.
Do you see my files — or my card?+
Neither. Conversions run entirely in your browser; there is no upload endpoint. And checkout runs through a merchant of record (Lemon Squeezy) that handles VAT — we never see or store your card.
Does the paywall ever block a conversion?+
Never. Every conversion, the token count and the chunk plan are always free and unlimited. Pro only unlocks the workflow features.
