We build free browser-based tools that respect your privacy. No accounts, no uploads to servers, no tracking beyond basic analytics. Here's what we've made:

Mind maps, flowcharts, whiteboards, Gantt charts, brainstorming canvases, and over 200 other visual tools — all free in your browser.
SCOUTb2 — AI Website Auditor
Check accessibility, performance, and SEO across your entire site. Scan up to 10,000 pages with scheduled monitoring and detailed reports.
COMBb2 — 16 AI Image Tools
Upscale, deblur, restore faces, remove backgrounds, and more. 100% local processing — nothing gets uploaded anywhere.
b2KIT — 2,700+ Free Browser Tools
Documents, text, code, design, math, finance — everything runs locally in your browser. No signup needed, no data collected.
All tools are built by the same team behind Onco Briefs. We believe useful software should be free, private, and run where your data already lives — on your own device.
