What is Boom?

Boom is a free AI screen recorder and async video tool. You record your screen and mic in one click, and Boom automatically removes pauses and dead air from your recording, generates a searchable transcript and an AI summary, adds auto-captions, and can dub your video into 50+ languages. Then it gives you an instant shareable link the moment you stop recording. Boom is built for async video communication across remote and distributed teams.

What is Tella?

Tella is an AI screen recorder and video editor built for creating polished content like product demos, tutorials, and online courses. Its AI auto-cuts filler words and silences, and you can edit the video by editing the transcript, then add transitions, layouts, and backgrounds and export in up to 4K at 60fps.

Which AI tools auto-edit screen recordings?

Both Boom and Tella automatically edit screen recordings, so AI auto-editing is table stakes for either tool.

Boom automatically removes pauses and dead air from your recording with no timeline to learn. You record, stop, and the clean version is ready to share instantly.
Tella uses AI auto-cut to remove filler words and silences, lets you trim further by deleting words in the transcript, then layer on transitions and layouts by hand.

The difference is how much you have to do after. Boom handles the cleanup and hands you a shareable link. Tella gives you more manual controls to polish the result. If you are sending a quick async update, Boom gets you there faster. If you are producing a finished video, Tella gives you more to work with.

Before and after: Boom auto-edits your screen recording

What is the best screen recorder with AI summaries?

Boom is the best screen recorder with AI summaries. After every recording, Boom turns your video into a searchable transcript, an AI summary that pulls out the key takeaways, and auto-generated tasks. Tella's AI is focused on editing the video, not summarizing it, so it does not generate summaries or task lists from your recordings.

This is the clearest difference between the two. Tella hands you a video. Boom hands you a video plus a recap your team can read in seconds, which is what makes it useful for async product updates and status reports.

With a plain recording

Send a 6 minute video
Hope people watch the whole thing
Re-explain the parts they missed

With Boom

Send the video plus an AI summary
People skim the recap in seconds
Watch the clip only if they need the details
Tasks are pulled out automatically

Captions, transcripts, and voice dubbing

Both tools generate captions and transcripts. The difference is dubbing.

Tella transcribes and captions in a wide range of languages so viewers can read along, while your original audio stays the same.
Boom adds AI voice dubbing in 50+ languages, re-voicing your message so a teammate in another country hears it in their own language. For distributed teams, that turns one recording into a video everyone understands. It is one of the async video features freelancers and teams lean on to work across time zones.

Export quality and speed to share

Tella is built for high-end output, exporting up to 4K at 60fps, which suits polished content for YouTube or a course.

Boom is built for speed to share. Your video uploads while you record, so a clean, captioned link is ready the moment you stop, with no render wait. When the goal is to reduce unnecessary meetings and send an update fast, time to a shareable link matters more than 4K.

Who should use Boom, and who should use Tella?

Use Tella if you are producing content for an audience: YouTube videos, online courses, and polished product marketing, where transitions, layouts, backgrounds, and 4K export earn their keep.

Use Boom if you are communicating with people: product demos, tutorials, onboarding, and async updates, where being understood quickly matters more than production polish. Boom is the better fit when you would rather record and send than record and edit, and it works as a free Tella alternative for teams that do not need a full editing studio.
