How it works
From an audio file to a video people can scroll past and stop on.
Upload the audio, pick a visual treatment, generate captions from speech, then export the audiogram or keep editing it as a full video.
Upload the audio
Start with a podcast clip, voice memo, interview pull-quote, narration take, or extracted speech track that should travel as a video.
Audio uploaded
Pick the visual treatment
Use an animated waveform on top of cover art for a classic audiogram, or let ngram match each spoken section to a scene with AI visuals and motion graphics.
Visuals selected
Caption the speech
ngram transcribes the spoken audio through AssemblyAI, places timed captions, and lets you tweak wording, line breaks, and styling before export.

Export the clip
Render a 9:16 podcast clip for Reels and Shorts, a 1:1 audiogram for LinkedIn, or a 16:9 video for YouTube - all from the same project.

What it can do
What audio becomes in ngram.
Audio-to-video work fits two paths inside ngram: a quick captioned audiogram with a moving waveform, or a longer video where each spoken beat gets its own scene.
Animate a waveform over the audio
Pair the speech track with an animated waveform on cover art, a branded background, or a still image so the clip feels alive on a silent social feed.
Burn in captions from the speech
AssemblyAI transcribes the audio, ngram places timed captions, and the brand kit styles font, color, and position before the video is burned in.
Learn more about captionsMatch scenes to the narration
When the audio is longer than an audiogram should be, ngram maps each spoken section to its own scene with generated visuals, B-roll, or product callouts.
Learn more about AI visualsApply brand styling end to end
Brand kit fonts, colors, logos, intros, outros, and motion style follow the audio into the audiogram or the scene-matched video without manual restyling.

Render the same audio project as a 9:16 Reels clip, a 1:1 LinkedIn audiogram, or a 16:9 YouTube version with smart reframing per format.

| Compare | ngram | Headliner | Wavve | Descript |
|---|---|---|---|---|
