Free Chrome extension for LinkedIn

LinkedIn only lets you send voice messages from the phone app. Bub is a free Chrome extension that sends voice notes and native video from your laptop, right inside LinkedIn. Then clear every DM in one keyboard-first inbox where no follow-up slips.

Go on, try it. This is what Bub adds to LinkedIn's message box.

The problem

It's 2026. Your LinkedIn inbox still works like it's 2003.

01

Voice notes? Phone only.

LinkedIn lets you record voice messages in its app, and nowhere else. So mid-outreach you grab your phone, find the thread, record, and lose your flow. Every single time.

“Just spent hours looking for a tool to do LI voice notes and video and came across Bub. It actually worked and I'm so thankful.”Luke Williamson
02

Every DM looks the same.

Your message lands in a wall of grey text, right next to the ones they skip. The same font, the same bubble, the same scroll past. A voice is the one thing a template can't fake.

03

Follow-ups fall through.

LinkedIn's inbox has no reminders, no split inboxes, no snippets. So the reply that mattered sinks under the ones that didn't, and the deal quietly goes cold.

Hi, I'm Bub. I fixed it.

A tiny bird who lives in your LinkedIn message box. Voice notes, video and snippets inside LinkedIn, plus an inbox built for the way you actually work.

LinkedIn voice notes from your laptop

Say it. Don't type it.

Press ⌘⇧V in any LinkedIn chat, talk, and send. It arrives as a real LinkedIn voice message, the same kind their phone plays, right in their inbox.

  • From your laptop. No phone, no app, no breaking your flow.
  • Native, not a link. It plays inline, like any voice message.
  • New chats too. Open a conversation with a voice note.
  • Listen first. Preview, re-record, then send.

Your voice note made my day. Thursday?
LinkedIn video messages

Show them. In the DM.

Record your camera, your screen, or both with your face in a bubble. It plays right inside the conversation. No link to click, no app to open.

  • Screen + camera bubble. Walk them through it, face to face.
  • Plays inline. Native video, not a link to somewhere else.
  • One shortcut. ⌘⇧Y from any LinkedIn chat, or from your Bub inbox.
A faster LinkedIn inbox

Every DM. One fast inbox.

Bub turns LinkedIn messages into an inbox built for follow-ups. Split it by label, set a reminder with one key, and fly through it all without touching your mouse.

Privacy

Your inbox stays in your browser.

Helpful, not creepy. Here is exactly what Bub does and doesn’t do with your LinkedIn.

Your messages never touch our servers

Your DMs, connections, invites and profiles load from LinkedIn straight into your browser and stay on your device. Bub's servers never see them.

Zero automation

Bub never sends, archives, accepts or connects on its own. Every action on LinkedIn happens because you clicked or pressed a key.

Your LinkedIn, your browser

Bub works through the LinkedIn you're already signed into. No passwords, no proxies, and your LinkedIn cookies never leave your machine.

What we do keep

Only what you make in Bub, like labels, notes, snippets and reminder times, so they follow you to any computer. Plus counts, never the messages.

Built for people who live in their DMs.

Founders, SDRs, recruiters, anyone doing their own outreach. Everything you reach for, one key away.

Split inboxes

Hot leads, clients, candidates. Each label gets its own LinkedIn inbox, so the conversations that matter never share a list with the noise.

Hot leads 12 Clients 8 Candidates 5 Partners 3

Reminders

Press H. The chat leaves your inbox and comes back exactly when it's time to follow up, so no LinkedIn follow-up slips.

Keyboard-first

Your hands never leave home row. There's a key for every move, and ⌘K for everything else.

Live, like it should be

New messages and typing show up the moment they happen, and LinkedIn's own message box gets voice, video and snippets too.

People who send a lot of DMs, on Bub.

Finally a way to send voice notes on LinkedIn from my laptop lol. Been using it every day for my outreach. Asked the dev for one small feature and he actually added it within a week. Super handy, recommend it if you send a lot of voice notes.

Questions, answered.

Can I send a voice message on LinkedIn from my desktop?

Yes. LinkedIn only lets you record voice messages in its mobile app. Bub is a free Chrome extension that adds a record button to LinkedIn's message box on your computer, so you can send a native voice message from your laptop, 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 into the chat as a native video that plays inside the DM. Unlike Loom, there's no link to paste and no viewer page. The video lives in the LinkedIn message itself.

How to send a video message on LinkedIn →

How long can a LinkedIn voice message be?

Up to 60 seconds. That's LinkedIn's limit for voice messages, on the phone app and with Bub on desktop. For anything longer, send a video instead: Bub records up to 15 minutes, and it plays right inside the DM.

LinkedIn voice message length, explained →

Do you use a proxy or log in to my LinkedIn account?

No. We never log in to your LinkedIn account, never ask for your password, and never use proxies. Bub works through the LinkedIn you're already signed into in your own browser, so every message goes out exactly as if you'd sent it from LinkedIn yourself. That's what makes Bub one of the safest LinkedIn tools you can use. Sign out of LinkedIn in your browser and Bub simply stops until you sign back in.

Will using Bub get my LinkedIn account banned?

LinkedIn restricts automation and scraping: bots that auto-connect, mass-message or harvest profiles. Bub does none of that. It adds tools to your message box and inbox, and you press send on everything, exactly like normal LinkedIn use.

Does Bub store my LinkedIn messages or contacts on its servers?

No. Your messages, connections, invites and profile info are read from LinkedIn inside your own browser and kept on your device. They never reach Bub's servers. We only save what you create in Bub (labels, notes, snippets and reminder times) so it follows you to any computer, plus counts like "sent 12 messages today", never the messages themselves.

Does Bub automate anything on LinkedIn?

No. Bub never sends a message, archives a chat, accepts an invite or connects with anyone on its own. Every action on LinkedIn happens only when you click a button or press a key. The only thing running in the background is a quiet check for new messages so Bub can show you a notification, and you can turn that off in Settings.

What's the Bub inbox?

A fast, keyboard-first inbox for your LinkedIn messages. Split it into inboxes by label, set reminders so follow-ups come back on time, use snippets, and move through it all with the keyboard. It's part of Bub Pro, with a 14-day free trial.

Is there a Superhuman for LinkedIn?

Yes, that's the Bub inbox. It's a fast, keyboard-first inbox for your LinkedIn messages: split inboxes by label, follow-up reminders, snippets, notes on people, a key for every move and ⌘K for everything. Try it free for 14 days, no card needed.

Superhuman for LinkedIn →

How do I never miss a follow-up on LinkedIn?

Set a reminder on the chat. In the Bub inbox, press H on any conversation and pick when. The chat leaves your inbox and comes back at the top at that time, so you follow up on time. The "Waiting for their reply" view shows every chat where the next move is theirs.

How to set follow-up reminders on LinkedIn →

Can I label or organize my LinkedIn messages?

Yes. LinkedIn messaging only has a few fixed filters, but in the Bub inbox you can add your own labels to any conversation with L, like prospects, clients or candidates. Each label can become its own split inbox, so the chats that matter never get buried.

How to organize LinkedIn messages →

Does it work with Sales Navigator?

Bub works in LinkedIn messaging on linkedin.com: voice notes, video and snippets in every chat, plus the Bub inbox. Sales Navigator's own message box isn't supported, so send from LinkedIn messaging or your Bub inbox instead.

Is Sales Navigator worth it? →

Is Bub free?

The Bub extension is free, always. Send unlimited voice notes, videos and snippets right inside LinkedIn, no card, no catch. The Bub inbox is Bub Pro: try it free for 14 days, no card needed, then it's $15 per LinkedIn inbox a month, billed yearly, or $35 monthly. Teammates are free.

What does “per LinkedIn inbox” mean?

You pay for each LinkedIn account that uses the Bub inbox, not for each person. One inbox is one LinkedIn account. Buy 3, and any 3 LinkedIn accounts in your workspace can use the Bub inbox. Switch which ones whenever you like.

Can my team use Bub?

Yes, and teammates are free. Invite as many people as you like to your workspace. Everyone signs in with their own email, uses the LinkedIn inboxes your workspace pays for, and shares the same snippets.

What happens when my inbox trial ends?

Nothing is lost. Your labels, notes, snippets and reminders stay saved, and the extension keeps working in LinkedIn. Pick a plan whenever you're ready and your inbox opens right where you left it.

Which browsers and computers work?

Any Chromium browser: Chrome, Edge, Brave and Arc, on Mac and Windows.

How is Bub different from Kondo?

Kondo is a paid inbox app for LinkedIn, with no free plan or free trial. Bub's Chrome extension is free forever and adds voice notes, native video and snippets right inside LinkedIn itself, so you get them without moving to a new inbox. When you want a faster inbox too, Bub Pro adds split inboxes, reminders and keyboard shortcuts, and teammates are free.

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 and never slip, Bub is built for you.

Stop using a LinkedIn inbox that sucks.

Send LinkedIn voice notes and native video from your laptop, then clear every DM in one fast, keyboard-first inbox. The Bub Chrome extension is free, forever.
