Material costs are 8% over the Q3 budget line. Want a revised forecast in the roadmap?

Twelve tools that already know each other.

A file in a channel is the same file in CoreFiles. A task on a project is the same task in your calendar. Nothing to integrate, because nothing was separate to begin with.

Chat

Direct messages, group chats, channels and threads — end-to-end encrypted by default.

CoreMeet

Voice, video and screen sharing, with guest links for people outside the company.

CoreFiles

Storage with version history, permissioned share links and a 30-day trash.

Documents

Write documents, spreadsheets and decks in the browser, together, in real time.

Calendar

Shared schedules and invitations, with two-way Google Calendar sync.

Mail

Your existing mailboxes over IMAP and SMTP, or Gmail and Outlook, in one inbox.

Tasks

Projects, milestones and assignments, with the work attached to them.

Notes

A private vault, encrypted with a key derived from your own passphrase.

CoreForms

Fifteen field types, public links, and every response where you can query it.

Whiteboards

A canvas that lives in CoreFiles like any other document, with the same sharing.

CoreDB

Collaborative databases you query in SQL — or in plain language, if you prefer.

Dashboards

Live numbers from your own data, fed by inbound webhooks from anywhere.

An assistant with its hands on the actual work.

Most assistants can talk about your documents. This one opens them, edits them and saves them back — the same files your colleagues are working in, with the same permissions you have.

It reads spreadsheets and writes formulas, drafts and files your mail without ever sending it, queries your databases, builds dashboards and produces decks. It runs on a schedule if you want it to, and it remembers what a project is about between sessions.

  • Runs on Claude, Gemini, OpenAI or DeepSeek — or on a local model, so nothing leaves the building
  • Bring your own API key, or let an administrator set the policy for everyone
  • A local-models-only mode that refuses every cloud provider outright
  • Included in every plan, at no extra cost per person

writeQ3 Roadmap.docx — revised forecast
Materials are 8% over the Q3 line, driven by steel. Labour and logistics are on plan. I have added a revised forecast to the roadmap and left the original as version 4.

Encrypted where it counts — and we will tell you where it doesn't.

Plenty of products say "secure". Here is the specific answer, including the parts we are still building.

dm protocol X3DH + Double Ratchet
dm cipher XChaCha20-Poly1305 · a key per message
groups AES-256-GCM · shared key
vault kdf PBKDF2-SHA256 · 210 000
transport TLS 1.2 / 1.3
e2ee dm · groups · channels · attachments
at rest corefiles · aes-256-gcm · server-held key
3p tracking none

What is end-to-end encrypted?

Direct messages, group chats, server channels and their attachments — encrypted in your browser before they are sent, so we cannot read them. Meeting media too, on supported browsers.

And what isn't?

Files in CoreFiles. On a CoreOffice workspace they are encrypted at rest, but with a key the server holds — so technically we can read them. Calendar entries, tasks and form responses are ordinary database rows and are not encrypted at all. The one exception is a file you send inside a conversation: those are sealed in your browser with the conversation key, like the messages around them. We would rather write all of that down than let you assume otherwise.

Is this the Signal protocol?

For one-to-one messages, yes — the same construction. Direct messages run over X3DH and the Double Ratchet: a session per device and a fresh key for every message, which gives forward secrecy and post-compromise security. Our own implementation of the published spec, not Signal's library, and not independently audited. Group chats and channels still share one group key and are not forward secret — that is the next piece.

Where does it run?

In EU data centres, or on a server you own — one command on your own Ubuntu machine, talking to no external service. Self-hosting is on every plan, not an enterprise upsell.

Run it in our cloud, or on your own machine.

The same product either way. What changes is who operates it and who holds the keys — and self-hosting is on every plan, not an enterprise upsell.
