Your ideas matter.

Create teams and #channels

Create teams for your company, your family or your friends.

Then, create project-specific channels for your coworkers and anyone you want to include in your conversations.

The best part? Drastically less email, no more CCing a dozen people on an email, no more hunting and digging through all of your email for what someone said, or an attachment you can't find.

Instead, you'll be more efficient, productive, organized, and secure.

No more passwords

Hackers love weak passwords. To protect your security and privacy, Semaphor will generate a secure recovery key for you at sign-up. (Be sure to store it in a safe place like Encryptr.

When adding your mobile device, go to your profile and choose Add a Device. Your unique Semaphor pattern will appear on screen; just scan it with your phone and you will be immediately logged in to your account.

Share Confidently

No compromises. If you have a sensitive document to send, a great idea to protect, or a password to share, attach it to your conversations or private messages on Semaphor.

Our Zero Knowledge architecture makes everything encrypted end-to-end, completely private and secure.

Truly Private Messaging

Every conversation, message and file you share is cryptographically secure.

From sharing highly sensitive files to making lunch plans with colleagues, use private messaging with any of your verified contacts.

Use your unique Semaphor pattern

When you sign up, you will generate your Contact Card - a unique Semaphoric pattern that acts as your public encryption key.

Verify the identity of your coworkers, friends and family digitally or in-person (by scanning their contact card), and build your web of trust.
