Your team shares secrets every day.
Most of them end up in Slack.
VoidNote gives every person on your team a secure, client-side encrypted way to deliver credentials — to colleagues, contractors, CI runners, and AI agents — without leaving a trace in chat history.
Where your team's secrets actually live
Slack DMs
Credentials sent in messages live in workspace history indefinitely. Former employees, admin exports, and workspace breaches all expose them.
Email threads
Credentials forwarded to a contractor sit in both sent and received inboxes, on every synced device, for years.
Shared .env files
A .env in Dropbox or a shared drive stays accessible until someone manually revokes access — which rarely happens after off-boarding.
Git history
A key committed once — even in a private repo — is permanently in history. GitHub scanning bots find and abuse exposed keys within minutes.
Every security audit finds the same thing: credentials scattered across communication tools, with no expiry and no audit trail of who saw what. The problem isn't discipline — it's that there hasn't been a fast, frictionless alternative.
How teams use VoidNote today
- 1
Developer onboarding
Instead of pasting a list of API keys into Slack, create a single VoidNote with all the new joiner's credentials. They read it once — it self-destructs. No credentials in the onboarding thread.
- 2
Contractor credential handoff
Grant a contractor exactly the access they need for the engagement, via a single-use link. When the note self-destructs after they read it, there's nothing to revoke and no copy persisting in their inbox.
- 3
CI/CD pipeline bootstrapping
Deliver the initial secrets a new pipeline needs via a VoidNote link. The runner reads it once, loads the credentials into environment variables, and the link is dead.
- 4
AI agent provisioning
Drop a VoidNote link into a Claude Code CLAUDE.md or system prompt. The agent reads the credentials once, they're in memory, and the note self-destructs. Keys never in a file or conversation log.
- 5
Incident response
During an incident, rotating credentials and securely distributing replacements to the people who need them — without broadcasting to a whole Slack channel — is a frequent bottleneck. VoidNote handles it in seconds.
Teams are free
Anyone can create a note without an account. When your team wants more, every member gets a free account, and one of you can set up a team in a minute. There's nothing to buy.
Invite by email
Owners and admins invite colleagues by email. They join with their own free account.
Roles
Owner, admin or member. Admins can invite and remove members; only the owner can make admins.
Off-boarding
Remove someone from the team when they leave. Their links were never stored in a shared inbox to begin with.
API keys for pipelines
Each member can generate an API key for the SDKs and CLI — for CI runners, scripts and agents.
Streams
Live encrypted channels for piping secrets or logs between people, terminals and agents.
File vault
Encrypted files that are destroyed after the first download.
Why teams can trust VoidNote
A registered UK company
Quantum Encoding Ltd, registered in England and Wales (Company No. 16575953) and subject to UK GDPR. Notes are encrypted on the sender's device, so we hold no readable note content to hand over.
Encrypted before upload
Notes are encrypted on the sender's device and stored without their keys. Note links keep the key in the URL fragment, after the #, which browsers never send to our servers.
No tracking or analytics
No Google Analytics, no session recording, no ad pixels. The only cookie is a functional session cookie required for login.
Verify it yourself
Open DevTools, create a note, watch the network tab. No plaintext, no key. Open-source SDKs on GitHub. The encryption model is fully auditable.
