The page remembers
who wrote what.
Collaborators, agents, audio/video calls & originality checks — working in the same line, not separate tabs.
Welcome to inkk.ai
Collaborative AI writing workspace with real-time co-editing, multi-provider model routing, integrated audio/video calling, and side-by-side chat copilot.

Multi-Provider Choice.
Select separate AI models for Editor vs. Chat.
Configure distinct AI models independently for long-form document drafting and real-time chat copilot tasks. Zero vendor lock-in with seamless model switching on the fly.
Everything else, already here.
inkk Video & Audio Calls
Built-in peer-to-peer audio and video calling directly inside documents — no third-party app needed.
Free AI Models — Always
Continuous, unmetered access to open community models (Gemini Flash, Llama 3.3) at zero cost.
Full Revision History
Character-level timeline tracking every edit, author, and timestamped document version.
Group Workspaces & Pages
Organise documents like a book — chapters and pages per group. Admins control exactly who can view, edit, or comment on each page.
Browser Extension COMING SOON
Bring inkk AI into any webpage — highlight text, run prompts, and push AI output back into your documents without leaving your browser.
Live AI Simulations in-doc
Ask the AI to generate interactive HTML/CSS/JS simulations — DNA strand models, physics demonstrations, chemistry visualisations — rendered directly inside your document.
AI that writes & simulates.
Students, researchers and educators can prompt inkk to generate fully interactive HTML/CSS/JS widgets embedded live inside any page — no coding required.
DNA Strand Visualiser
Interactive double-helix with base-pair labels. Rotate, zoom, and annotate in real time inside the document.
Physics Simulation
Pendulums, projectile motion, gravitational orbits — live canvas animations tuned to your parameters.
Live Data Charts
Auto-generated bar, line, and pie charts from inline data — updates as collaborators edit the source table.
One document. Two very different outcomes.
Same paste, same file size — recorded live, not staged.
inkk.ai
ChatGPT writes for you.
inkk.ai builds with your stack.
ChatGPT and Claude are standalone chat boxes. inkk.ai is an extensible collaborative document engine with real-time caret attribution, drop-in embedding, and full API control.
AI-vs-Human Authorship
Trace exactly which AI model generated a passage versus which teammate typed a sentence — tracked dynamically down to individual character keystrokes.
[Model GPT-5] inserted block @L15-28
Drop-In Document Canvas
Embed inkk's full collaborative editor directly into your web product, LMS, or SaaS portal with clean iframe and JS SDK integration.
Append & Update via API
Programmatically create, update, and append content to live documents using REST endpoints — fully compatible with n8n, Zapier, and custom webhooks.
