Knotbook Pro
One-time purchase. Lifetime updates. Up to 3 devices per license. Pay once, own forever — no subscription, no telemetry.
Live collaboration, databases, canvas, tasks, version history, and the web clipper are free for everyone. Pro unlocks KnotAI, PDF editing, and the rest below.
Payment is processed by Razorpay (UPI, cards, netbanking, wallets). Your license key appears on My Licenses within seconds of successful payment.
What Pro unlocks
The features below stay disabled in the free build. Everything else in Knotbook is unlocked from day one.
KnotAI
Local-first AI: chat with your notes & PDFs, summarize, write-on, run agent flows. Powered by your own machine — no token bills, no data leaving your laptop.
PDF editing & annotations
Highlight, comment, stamp, and edit text on any PDF inside Knotbook. Save annotations alongside the file, or export a flattened copy.
Note → PDF export
Turn any note into a polished PDF with embedded fonts, proper headings, and your theme's typography.
Advanced graph view
Cytoscape-powered visualization of every note, every wikilink, every backlink across your workspace.
Linked devices
Pair a Knotbook companion app over Wi-Fi. Desktop stays the source of truth; mobile reads & writes through the local link.
Priority support & updates
Direct line to the team for bug reports and feature requests, plus every future Pro feature included at no extra charge.
