Up and running in a minute

No setup. No account to start.

1

Add Bub to Chrome

One click from the Web Store. No sign-up, no config, nothing to learn.

2

Open any LinkedIn chat

Bub appears right in the message toolbar β€” the blue guy next to the emoji button.

3

Record, rewrite, send

Voice, video, AI, snippets, library β€” all where you already type. You always press send.

The part other tools won't tell you

Bub makes your composer better. That's all it does.

The tools LinkedIn actually restricts are scrapers and auto-senders. Bub is neither.

Never scrapes

Bub doesn't collect profiles, emails, or connection lists. It doesn't read the page for data. It only adds tools to the box you're typing in.

Never automates

No auto-connect, no bulk messaging, no bots acting for you. Nothing happens unless you do it. You write, and you press send.

Your content stays yours

Recordings live in your browser. Rewrite sends only the draft text to the AI β€” never your contacts, and we don't store or sell your messages.

Free for you, forever. Use me on your own and you'll never pay a cent β€” no trial, no credit card, no catch. Down the road we'll add paid plans for teams who want a shared library and workspace tools, but solo reps like you always stay free. Made by the team behind OpenSignals, the buying-signal platform for outbound.

Not just a toolbar

I've got a little personality.

I wave when you arrive, cheer when you send, and sulk when you delete a take. Small moments that make the grind a bit lighter.

I say hionce, when you land
I celebrateconfetti on every send
I sulkwhen you delete a take
I restwhen you're away
Straight answers

Questions reps actually ask.

Will using Bub get my LinkedIn account banned?

No. LinkedIn restricts automation and scraping β€” bots that auto-connect, mass-message, or harvest profile data. Bub does none of that. It only adds tools to your message composer, and you press send on everything. You stay fully in control, exactly like normal LinkedIn use.

Is my data safe? What leaves my browser?

Your recordings are created and held in your browser. The only thing that leaves is the draft text you choose to rewrite, which goes to the AI to sharpen it β€” never your contacts or conversations. We don't store or sell your messages. Full details are in our privacy policy.

Does it work with Sales Navigator?

Yes. Bub lives in the LinkedIn message composer, so it works in regular LinkedIn and Sales Navigator inboxes alike.

Is it really free? What's the catch?

Yes β€” free forever if you use Bub on your own. No trial, no credit card, no locked features. Later on we plan to add paid plans for teams who want a shared library and workspace tools, but individual use always stays free. Bub is made by the team behind OpenSignals.

Which browsers and computers work?

Any Chromium browser β€” Chrome, Edge, Brave, and Arc β€” on both Mac and Windows.

How do I remove it?

One click. Right-click the Bub icon and choose remove β€” it's gone, with nothing left behind. Add it back anytime.

Everyone else is still sending plain text.

Be the message they actually remember.

Add me to Chrome and I'll be waiting in your next LinkedIn conversation β€” voice, video, AI, snippets, and library, all from your desktop.
