Polished demo and course recording
Tella alternative for teams who need reach over polish
Tella is aimed at people whose recordings are the product — demos, launch videos, paid courses. It gives you backgrounds, layouts, zooms and clip-based editing so a raw capture comes out looking designed. Boom optimises for a different thing: getting a clear explanation to someone quickly, in a language they actually speak.

The short answer
Choose Boom if…
Choose Boom if the recording is communication rather than content — a status update, a bug report, an onboarding walkthrough — and especially if it needs to reach people who do not share your language.
Tella may suit you better if…
Choose Tella if the recording is a deliverable — a landing-page demo, a course lesson, a launch video. Its clip-based timeline and automatic layout presets do more of the work for you, and it supports very long single clips.
Where Boom is better
A full studio, not just a trimmer
Zoom regions with focus point and intensity, custom video backgrounds, burned-in subtitles in four styles with colour control, and intro/outro clips from your library — all on the recording you just made, with no timeline to assemble.
One take, many languages
Boom Pro clones your voice and replays the recording in 50+ languages with native pronunciation. A course lesson or product demo reaches a market Tella would require you to re-record for.
Automatic post-production
Boom trims silences, transcribes and extracts action items without you opening an editor. Tella gives you better tools; Boom tries to make the tools unnecessary.
Lower ceremony for everyday video
Record, stop, share. For internal communication that speed matters more than a rounded corner.
Canvas for explaining ideas
Boom includes an infinite canvas for sketching an explanation while recording, useful when the thing you are explaining is not on your screen yet.
Why people look for a Tella alternative
Polish they do not need
Teams adopt Tella for one launch video, then find the production affordances slow down everyday communication.
Audience speaks another language
A beautifully produced demo still only works for people who understand it. Re-recording per market is expensive.
Editing time adds up
Clip editing is powerful but manual. Automatic cleanup wins when volume is high and stakes per video are low.

What Tella does well
Recordings that look intentionally produced
Backgrounds, padding, rounded corners, automatic zooms and camera layouts turn an ordinary screen capture into something you can put on a marketing page without further editing.
Clip-based editing built in
Tella splits recordings into clips you can trim, reorder and re-record individually, which means fixing one fluffed section without starting the whole take again.
Where Tella runs out
Production effort on every recording
The features that make Tella output look good are choices you have to make. For a two-minute answer to a colleague, that is friction rather than value.
No voice translation
Tella polishes how a video looks. It does not change what language it is in, so a global audience still needs either subtitles or a separate recording.
Aimed at content, priced accordingly
Tella is built for people producing video as an output. Teams who simply want to stop scheduling meetings tend to be paying for capability they do not exercise.
When Tella is the better call
One case where we would point you elsewhere.
Fully produced marketing video
Tella applies zooms and layouts automatically and lets you re-record individual clips. If a recording is a published deliverable rather than a message, that automation saves real time.
Who each one suits
Boom is a better fit for
- Internal updates, demos and bug reports that need to be fast
- Anyone publishing the same explanation in several languages
- People who would rather not open an editor at all
Tella is a better fit for
- Course creators and educators producing lesson libraries
- Marketing teams shipping demos onto landing pages
- Anyone who needs GIFs or embeds as a primary output
- Long-form recording in a single unbroken clip
Moving across from Tella
- 1
Create a free Boom account — 25 recordings, five minutes each, 1080p and 5 GB of storage. No card required. Free recordings carry a watermark and player ads; Boom Pro removes both and the length cap.
- 2
Record your next explanation in Boom rather than migrating history. Existing Tella links keep working, so there is no cut-over moment.
- 3
If you need transcripts, AI summaries or dubbing into 50+ languages, move to Boom Pro. Everything else stays on the free plan.
- 4
Keep Tella for anything in the list above where it genuinely wins. Running two tools is a reasonable outcome.
Tella questions, answered
It depends what you are recording. For internal communication and multilingual reach, Boom fits better. For polished course content and marketing demos, Tella is the stronger tool and Boom does not match its editor.
