The message box LinkedIn forgot to build.
Send voice notes and native video on LinkedIn — from your desktop, no phone needed. Plus AI rewrite, snippets, and a saved library, right inside the composer.
↑ That blue guy is Bub, living right in your composer. Tap record to try it.
Everything happens in the composer.
No new tab, no phone, no copy-paste. Click a tool to see it work — right where the conversation already is.
Try it — tap the red button, then send.
Screen, camera, or both — it plays right inside the message.
Rough draft in, sharp message out — in your voice.
Type ;bub in the box and watch it expand.
Nail a great intro once. Resend it in a tap.
Your whole toolkit, one keystroke away.
Voice note, video, AI rewrite, saved reply. Hit the keys and Bub opens right where your cursor already is. No menus. No mouse. No breaking stride. Think it, key it, sent.
Or just type /s mid-sentence to drop a saved reply without lifting a finger. On Windows, swap ⌘ for Ctrl.
No setup. No account to start.
Add Bub to Chrome
One click from the Web Store. No sign-up, no config, nothing to learn.
Open any LinkedIn chat
Bub appears right in the message toolbar — the blue guy next to the emoji button.
Record, rewrite, send
Voice, video, AI, snippets, library — all where you already type. You always press send.
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 — 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 — no trial, no credit card, no catch. Whether you're a founder, an SDR, or anyone doing their own outreach, Bub stays free.
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.
Questions reps actually ask.
Will using Bub get my LinkedIn account banned?
No. LinkedIn restricts automation and scraping — 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 — never your contacts or conversations. We don't store or sell your messages. Full details are in our privacy policy.
Can I send a voice message on LinkedIn from my desktop?
Yes. LinkedIn only lets you record voice messages in its mobile app — there's no button for it on the desktop site. Bub adds one: a record button right in the LinkedIn composer on your computer, so you can send a native voice note from your desktop, no phone needed. Notes can be up to 60 seconds.
Can I send a video in a LinkedIn message? Is Bub like Loom for LinkedIn?
Yes — record your camera, your screen, or both, and Bub drops it straight into the chat as native video that plays inside the DM. Unlike Loom or Vidyard, there's no link to paste and no hosted viewer — the video lives right in the LinkedIn message itself.
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 — free forever. No trial, no credit card, no locked features. If you're a founder, an SDR, or anyone doing your own outreach, Bub stays free.
Which browsers and computers work?
Any Chromium browser — Chrome, Edge, Brave, and Arc — on both Mac and Windows.
How do I remove it?
One click. Right-click the Bub icon and choose remove — it's gone, with nothing left behind. Add it back anytime.
Who is Bub for?
Founders, SDRs, recruiters, and anyone doing their own outreach on LinkedIn. If you write your own messages and want them to stand out — with voice, video, and sharper copy — Bub is built for you, and it's free for individual use, forever.
Be the message they actually remember.
Add me to Chrome and I'll be waiting in your next LinkedIn conversation — voice, video, AI, snippets, and library, all from your desktop.
