Auto Subtitle Generator by ngram
Auto Subtitle Generator for every product walkthrough
Drop a video or click to upload
MP4, MOV, WebM, MKV - the auto subtitle pass uses the speech track
What it does
Generate subtitles for product demos, customer tutorials, and training recordings without exporting to a separate caption tool. Fix each line and reuse the same project for localized versions.

How it works
From upload to auto-generated subtitles.
ngram runs the transcription, places timed subtitle lines on the timeline, and hands the project back so the words, timing, and styling stay editable before export.
Upload the speech source
Drop in a video, audio file, webinar replay, demo, or share-link URL. Clearer speech needs fewer corrections after the auto subtitle pass.
Speech source ready
Run the automatic transcription
ngram transcribes the audio with AssemblyAI and writes the subtitle lines onto the timeline in one pass, with timing aligned to the spoken cadence.
Auto-generated subtitles in
Review words, timing, and style
Fix product names, acronyms, and line breaks. Nudge any timing the auto pass got close but not perfect. Apply caption font, color, and position from the brand kit.
Lines reviewed and styled
Export or keep working
Render the captioned video, hand it to translation for a localized pass, resize for vertical and square cuts, or keep editing the rest of the project in the same workspace.
Ready for channels
What it can do
What ngram's auto subtitle generator does.
The automatic pass writes the lines so a captioned video starts from a reviewable timeline instead of a blank caption track.
Generate timed subtitles in one pass
Upload the file and the auto subtitle generator returns lines with timings already snapped to the speech, so the first review is a polish step, not a build.
Edit every auto-generated line
Correct product names, jargon, acronyms, speaker tags, and line breaks on the timeline before the captions are baked into the final render.
Carry the subtitles into another language
Reuse the same auto-generated transcript for translated subtitles, localized on-screen text, and multilingual voiceover instead of running transcription again.

Apply font, color, outline, position, and motion from the brand kit so auto-generated subtitles look the same across every video the team ships.
Learn more about brand kitMove from subtitle file to burned-in MP4
Keep the subtitle output as the foundation for a clean burn-in render. Prepare and review the subtitle layout separately in each widescreen, square, or vertical edit.

Why ngram
How ngram compares as an auto subtitle generator.
Most auto subtitle tools end at a styled caption file. ngram keeps the auto-generated subtitle pass attached to the editor, brand kit, translation, and the rest of the project.
| Compare | ngram | VEED | Submagic | Descript |
|---|---|---|---|---|
| Workflow fit | Auto-generates subtitles with the AssemblyAI engine inside the same project used for editing, brand kit, translation, and MP4 export. | VEED auto-generates subtitles in the browser with broad language coverage and exports captions burned in or as SRT, VTT, or TXT files. | Submagic specializes in auto-generated animated captions for short-form social video with emoji highlights and styled templates. | Descript auto-generates subtitles from its transcript and exports burned-in captions or SRT and VTT files alongside text-based editing. |
| How ngram fits | Keeps every auto-generated line editable on the timeline and tied to script, voiceover, and separately prepared channel edits for the next pass. | Dynamic and karaoke-style subtitle presets fit short-form creator content well. | It fits creators producing high-volume Reels, approved social channels, and Shorts content that need viral caption treatments. | It suits podcast, recording, and creator teams that want the transcript as the primary editing surface. |
| Best use | Best for teams that want auto-captioned business video to roll straight into the next demo, social cut, or localized variant. | ngram is stronger when the auto subtitle pass should stay connected to source material, brand kit, voiceover, and downstream variants. | ngram fits when the auto subtitle work belongs inside a business video project with brand kit, translation, and longer-form export. | ngram fits when the auto subtitle pass should sit alongside storyboard, voiceover, brand kit, and MP4 export. |
