Some demos are read. Others are watched, on a launch page, in an onboarding email, on a screen in the corner of a conference booth. For those, a voice that explains each step does more than a tooltip. You can now add a voiceover to any AtriumKit demo.
How it works
Every step of a guided demo, and every screen of a clickable one, can have its own narration. Open the editor and click Voiceover in the step list. Each step gets a script: what the voice says. It’s separate from the tooltip, because spoken words work differently from written ones. A tooltip says “Click New invoice.” A script says “Start a new invoice from here. It picks up the customer’s details for you.”
You don’t have to write the scripts from scratch. Write with AI drafts short, spoken lines that go with each tooltip instead of repeating it, and nothing changes until you pick the ones to keep. Or click Copy from tooltips and edit from there.
Three ways to give it a voice
- AI voice. Pick a voice from the library, filtered by gender and accent, and listen to samples. Set the speed and how steady or expressive it sounds. Click Generate and every step gets its clip. The voice is the same for the whole demo, so it sounds like one person.
- Record it yourself. Press record next to a step and read the script into your microphone, right in the editor. AtriumKit cleans up the audio: background noise suppressed, silence trimmed, levels evened out.
- Upload a file. Already have a voice actor’s takes or a recording from your studio? Upload MP3, M4A, WAV, WebM or Ogg, up to three minutes per step.
Recordings and uploads are transcribed automatically, and the transcript becomes the step’s script. We don’t clone voices. If you want your own voice in a demo, record it.
Captions included
Every clip comes with captions, one short line at a time, timed to the voice. You can edit any line and its timing. Turn on Captions on by default and viewers who watch with the sound off still follow along. Anyone can switch them off with the CC button.
In the player, sound stays off until the viewer clicks or presses a key, the way browsers expect. Turn on Advance after narration and each tooltip moves on when its narration ends, so the demo keeps the pace of the voice.
Every language you add
If you’ve translated a demo, the scripts are translated with the rest of the copy. Generate the voice for each language and viewers hear the demo in theirs, with captions to match. A language that’s missing a clip plays that step without sound rather than in the wrong language.
Names said the right way
AI voices can trip over product names. Add a Say it as spelling to a term in your knowledge kit’s glossary, like “Ledger-lee” for “Ledgerly”, and every AI clip in every demo that uses that brand kit says it that way. The captions and your copy keep the name as written.
Edits that don’t start over
Change one script and only that clip goes out of date. Generate remakes just the stale and missing clips, and clips whose script, voice and settings haven’t changed are reused for free. Narration is part of the demo, so undo and version history cover it like any other edit.
See who listens
With detailed analytics, each demo’s Analytics tab shows how many sessions played narration, how many viewers turned the sound on or turned captions on, and how much of each step’s narration was heard. If almost nobody turns the sound on, you’ll know the tooltips have to carry the story on their own.
Plans and allowances
Voiceovers are on Pro and Team, and on trials of both. AI voices use characters from a monthly allowance:
- Pro: 60,000 characters per creator a month, about an hour of speech
- Team: 120,000 characters per creator a month, about two hours
- 14-day trial: 10,000 characters, about ten minutes
A 10-step demo is about 1,200 characters. Recording and uploading your own audio don’t use the allowance at all. The Free plan doesn’t include voiceovers.
Try it
Open any demo, click Voiceover, and press Write with AI to get scripts for every step. If you’re on Free, a 14-day trial of Pro or Team includes voiceovers. The help article covers every setting, and the voiceovers page has the overview.
