Tell hk3k what you're working on. It creates the conversations, notes, tasks, and even the website to match — all in one place, all aware of each other. It remembers everything you tell it, so next time it's already up to speed.
Closest thing today: ChatGPT × Notion × your favorite notetaker — sharing one brain. Except hk3k actually does the work — building, organizing, and shipping, not just chatting.
Most users sign up for the workspace and discover this — the easiest way to ship a real website they've ever used. Tell Barnaby what you want. He plans the pages, writes the copy, sources the images, and publishes live at yourname.hk3k.ai — or your own domain.
This is a real exchange in hk3k. You type, Barnaby builds, you keep editing.
…and so on. As long as you want, as deep as you want.
Build Yours FreeWorried we'll mangle your design? Don't be. Type one prompt — Barnaby pulls your live site into your workspace exactly as it is. Now you can edit it conversationally, just like any hk3k site.
One is the original on fly.io. One is the same site, imported into hk3k. The pixels are identical — but in hk3k you rewrite the headline by typing "change it to X", not by editing code.
Ask a question. Barnaby pulls from your Notion workspace alongside the web — with real citations, not fabrications.
Type one paragraph. Barnaby creates folders, conversations, notes with real content, scheduled tasks, and a published website — all nested correctly, all undoable. Below: an actual result from a single message.
Build, know, and get things done — all with the same personalized AI
Describe a site in plain English — Barnaby plans the pages, writes the copy, sources images, and publishes live at yourname.hk3k.ai or your own domain. Edit conversationally afterwards.
Every image on your hk3k-built site comes from a properly licensed, creator-compensated library. No scraped art, no AI models trained on stolen work. Your site looks professional and respects the artists behind the photos.
Tell Barnaby what you want — "create a Space for my bakery project, add a task for tomorrow, and draft a launch note" — and he does all three in one turn. Every action is undoable.
Organize everything into Spaces — conversations, notes, tasks, files, and sites all live together in one tree. Drag-and-drop, nest folders, give each Space its own instructions.
Personalized search that learns your context, tone, and preferences. The more you use it, the more it feels like an AI that actually understands you.
AI writes hierarchical, interconnected notes from your conversations and memories — no manual organizing, no template-filling.
