Product — inkk.ai
The page remembers who wrote what.
inkk.ai is a real-time collaborative AI writing workspace. Type @ai anywhere in the document and the model answers inline — while collaborators, agents and calls work the same line, not separate tabs.
How it works
Every keystroke carries its author. A teammate drafts lines 1–14, GPT-5 inserts a block at line 15 — and the document remembers which was which. That is the whole product: a document that never forgets who did what.
Who it is for
Teams that write together
Collaborators, agents, audio/video calls and originality checks working in the same line — not separate tabs. Real-time co-editing for up to 128 editors, with per-page view, edit and comment control for admins.
Students and researchers
Prompt inkk to generate fully interactive HTML, CSS and JS widgets — DNA strand visualisers, physics simulations, live data charts — rendered directly inside the document. No coding required.
Builders
Drop the full collaborative editor into a web product, LMS or SaaS portal with a clean iframe and JS SDK, or drive live documents over REST — compatible with n8n, Zapier and custom webhooks.
Capabilities
Not another chat box.
A document engine.
Real-time co-editing
Thinkers, leaders and writers in the same document at the same time — the page remembers who wrote what. Fast sync keeps every caret live.
Multi-provider model routing
Separate AI engines for the editor and the chat copilot — GPT-5 Mini, Gemini Flash and more. Chat modes for Ask, Edit and Suggest. Switch models on the fly with zero vendor lock-in.
In-document video and audio calls
Built-in peer-to-peer calling directly inside documents. Talk it through without leaving the page — no third-party app needed.
Free AI models, always
Continuous, unmetered access to open community models — Gemini Flash, Llama 3.3 — at zero cost. Free models never draw down a token balance.
Character-level revision history
A timeline tracking every edit, author and timestamped document version — down to individual keystrokes.
Group workspaces and pages
Organise documents like a book — chapters and pages per group. Admins control exactly who can view, edit or comment on each page.
Live AI simulations
Ask the AI to generate interactive simulations rendered inside the document — double-helix models you can rotate, pendulums tuned to your parameters, charts that update as collaborators edit the source table.
Caret-level authorship
Trace exactly which AI model generated a passage versus which teammate typed a sentence — tracked dynamically as the document grows.
Embed and API
White-label the editor into any product, or programmatically create, update and append content to live documents over REST — POST /api/1/appendHTML and a workflow is synced.

A little surprise
This page was written together.
Two humans, one AI, zero separate tabs — the way every page on inkk.ai gets made.
