One workspace to replace them all
We're building the platform where notes, docs, messages, calendar, tasks, and AI live together, so your team can stop switching and start shipping.
The fragmentation tax
The average knowledge worker switches between apps constantly. Notes in one place. Messages in another. Calendar somewhere else. Tasks scattered across three tools.
Each switch costs more than time, it costs context. The mental map of what you were doing and why.
Coline exists to end that fragmentation.
Everything you need
Not separate apps. One unified system with AI woven throughout.
Channels & DMs
Real-time messaging with file tabs, threads, and presence. @kairo for AI assistance in any conversation.
Intelligent Calendar
Availability-aware scheduling, natural language event creation, and auto-generated meeting briefs 15 minutes before.
Universal Files
.doc, .sheet, .board, .note, .slide, .code — all in one drive. Convert between formats instantly. Collaborative editing built-in.
Kairo AI
Multi-model agent with workspace tool access. Detects actions in messages, drafts replies, creates events, tracks commitments.
Principles
How we think about building software.
Ambient Intelligence
Kairo doesn't wait to be asked. It watches, understands, and acts — detecting meetings to prepare, commitments you've made, and connections you're missing.
Everything is a File
Notes, docs, spreadsheets, boards, code projects — all just files in your drive. Apps are editors, not separate products. Universal conversion: a doc becomes slides, rows become cards.
Context is Everything
The Knowledge Fabric connects every entity in your workspace — people, docs, messages, decisions. Ask 'when did we decide to use Postgres?' and get the full story.
Trust Through Transparency
AI detects but never acts without consent. Every suggestion shows its reasoning. Your data is encrypted, workspace-scoped, and never used to train models without explicit opt-in.
Friction-Free Execution
Tab to accept completions. One click to add a meeting from a DM. Pre-composed smart replies. Coline removes the micro-friction that kills productivity.
Unified, Not Bundled
Not ten apps sharing a login. One system where messages, calendar, files, and AI talk natively. A mention in a doc links to the meeting that discussed it.
How it fits together
Three layers. One system. Everything connected.
Primitives
Eight building blocks: messages, strings, numbers, dates, users, files, URLs, booleans. The same types everywhere.
Files
Everything is a file. Docs, sheets, boards, notes, code — all typed files that convert between formats instantly.
Workspaces
Personal plus shared team spaces with channels, DMs, drives, and calendars — all connected.
Where we're heading
We believe the best software disappears. It doesn't ask you to learn its quirks, manage its complexity, or remember where you put things. It just works.
We're building toward a workspace that truly understands your work. Where your notes, messages, calendar, and files are connected in ways that feel obvious in hindsight. Where switching between apps becomes a thing of the past.
The future of work isn't more tools. It's one tool that actually works.
