Welcome to Kuuumba

Kuuumba unifies your email, messaging, tasks, docs, and files into a single system, all linked together in one database. We built it with a Solid frontend and a Rust backend, so it's fast.

Core Blocks

For each block, we've studied the best prior art and tried to make it even better. For example, Email is faster than Superhuman with a unified inbox. Messaging is designed to be more focused, and less noisy, than Slack. Docs are simpler than Notion. Tasks steal from Linear but are less ceremonious (cycles, points, etc. are there if you really want but we advise not).

All of this works together as a single integrated system: one interface, one bidirectional database with shared memory for your agents.

The following are the core first-party blocks available in Kuuumba today. Each card links to that block's documentation page, with videos where applicable.

Key Features

Bidirectional @linking

When you @mention a document in a channel message, both the message and the document know about each other, so you can always trace where something has been discussed. This works across every block type: docs, tasks, emails, files, calls, etc.

Intelligent permissions

Permissions inherit from channels. @mention something in a channel and every member automatically gets access, so nobody has to ask "hey can you share this with me?"

Built for speed

Kuuumba has a Rust backend and a Solid frontend. Search is instant, collaboration is real-time, and everything has a keyboard shortcut.
