An AI co-host for your YouTube live streams
Bert sits on screen next to you, talks with you, keeps up with your chat and writes the replay’s title and chapters when you end the stream. It all runs in your browser.
What Bert does while you’re live
- Talks with you on camera. Ask him anything; he looks it up on the web and answers out loud in a few seconds, with sources.
- Fact-checks you. Names, dates and numbers are checked while you talk. A wrong one gets flagged, with the source, before your viewers do it for you.
- Answers your live chat. He picks the good questions, skips repeats, answers in the viewer’s language, and can show the question and answer on screen.
- Thanks supporters. Super Chats, stickers and new members get thanked by name with an on-screen alert, and a Super Chat’s question is answered first.
- Keeps the chat clean. Spam, scams and abuse are flagged for you or removed, and repeat offenders get a short timeout.
- Remembers your regulars. People who come back are welcomed by name, across streams.
- Packages the replay. When the stream ends, he writes the title, description and chapters, and can publish them to YouTube for you.
How it works
- Open the Studio in Chrome, Edge or Safari. Nothing to install, no gaming PC needed.
- Connect YouTube, or paste a server URL and stream key. Twitch, Kick, TikTok and LinkedIn work with a stream key too.
- Pick how Bert listens: always, only when you say “Hey Bert”, or push to talk.
- Go live. Bert joins as your co-host; helpers work in the background.
Not ready for an audience yet? Press Practice in the Studio: practice viewers react in a simulated chat, nothing is streamed, and you get a report on pace, silences and filler words afterwards.
Staying in control on air
A live co-host is only useful if he never makes you wince. These are the controls you have:
- Push to talk. Bert hears nothing until you press the mic or type. Best for streams where you only want him for questions.
- “Hey Bert”. He stays quiet until you call him by name. The wake word is detected on your computer, so the rest of what you say isn’t sent to answer you.
- Always listening. He hears everything, checks your facts and speaks up only when it adds something.
- Fact-check flags. A claim that doesn’t hold up comes with its source. Bert can say it on camera or just mark it for you and the edit, so a correction never surprises you mid-sentence.
- Moderation limits. Bert never bans anyone permanently on his own, never removes a paid message, and never answers or shows a flagged message on screen.
An example: from stream to replay
Say you stream a 70-minute Q&A about home batteries. Ten minutes in, this happens:
You: “The first home battery people actually bought was the Powerwall, back in 2012.”
Bert (flag on your screen): “Tesla announced the Powerwall in 2015. Source: Tesla’s press release.”
Viewer in chat: “Does a battery make sense without solar?”
Bert, on air: “Sometimes. If your power is cheaper at night, you can charge then and use it in the evening…”
When you end the stream, the after-stream autopilot drafts something like this for the replay:
- Title: Home batteries, honestly: costs, solar and your questions answered
- Chapters: 0:00 Intro · 4:12 What a home battery does · 10:05 Do you need solar? · 27:40 Costs and payback · 51:18 Chat Q&A
You edit what you like and publish it to YouTube from the same screen. This is an illustration of the format; your stream’s wording will differ.
After the stream: edit, caption and cut Shorts
Tick “Save a copy to Recordings” and the stream lands in your library when it ends. Open it in the browser video editor: make a transcript, cut the dead air by deleting words, remove filler words in one click, and add captions. Then let the AI find moments for Shorts, crop them to vertical on your face and publish them to YouTube.
Who it’s for
Creators who talk on camera: commentary, explainers, tech, finance, education, Q&A streams and solo talk shows. Bert is built for conversation, so he’s at his best when the topic matters and your chat has questions. Streaming a game or reacting to a video? Share your screen and Bert answers chat while you play; ask him and he looks at what’s on screen. He doesn’t watch it nonstop.
What it costs
Going live starts on Creator, €19 a month plus VAT: 750 credits, premium voices with faster replies, and every live helper. An hour of streaming costs 5 credits per platform; talking with Bert is counted by the minute. Try him first on the Free plan, no card needed. See all plans.
Questions
Can Bert say something wrong on air?
Yes, he’s an AI and can be wrong, even with sources. That’s why you choose when he speaks: push to talk or “Hey Bert” keep him quiet until you ask, and fact-check flags can go to you rather than out loud. He shows his sources so you can check before you repeat anything.
Which platforms besides YouTube?
YouTube, Twitch, Kick, TikTok and LinkedIn, and any platform that gives you a server URL and stream key, 2 at once on Creator and 4 on Pro. Bert answers live chat and thanks supporters on YouTube and Twitch; publishing the replay’s title and chapters works with YouTube.
How many chat messages will Bert answer?
Up to 30 an hour and 150 a day on Creator, 60 an hour and 400 a day on Pro. YouTube limits how many messages an app can post, so Bert picks the questions worth answering rather than replying to everything.
Do I need OBS or a gaming PC?
No. The Studio runs in Chrome, Edge or Safari on a computer and mixes your camera, screen share and Bert in the browser, then sends the stream to YouTube.
