The Otter.ai Alternative That Never Uploads Your Audio

Written by Kenji, Content Creator & Strategist · Updated 2026-08-06

Otter.ai transcribes meetings as they happen and hands you summaries afterwards, from its servers. Montaj is an Otter.ai alternative for a different deliverable: it transcribes on your device, and turns the transcript into word-by-word subtitles burned into a video you can post. Your audio never leaves your device. Free, no watermark.

Deliverable

Why an Otter.ai alternative depends on what you do with the words

Both tools turn speech into text, and there the similarity ends. Otter is optimised for a conversation with several people in it, where the value is being able to read it back later. Montaj is optimised for one person talking to a camera, where the value is the words appearing on screen in time with the voice.

If you have ever tried to caption a video by exporting a transcript from a meeting tool and pasting it into an editor, you have already found the seam this page is about.

Winner: Otter.ai for a written record; Montaj for subtitles

Privacy

Otter.ai vs Montaj on where the recording is processed

Otter processes on its servers, which is what makes live transcription and summaries possible across devices. It also means every meeting you record ends up somewhere other than your machine.

Montaj transcribes with WhisperKit on your device, and everything downstream is built there too:

Word-by-word karaoke subtitles with word-level timing, correctable inline.
One-tap silence removal across the clip, reversible and non-destructive.
Neural voice denoising, tuned for speech, running on the device.
No upload, no quota, and full offline operation once the models are cached.

Winner: Montaj, nothing is uploaded

Honest limits

Where Otter.ai wins

Montaj cannot join a meeting, cannot transcribe live, does not identify speakers across a long conversation and does not write summaries. For anyone whose problem is remembering what was said in a call, this is the wrong tool entirely.

Montaj is also vertical 9:16 only, single-user, and does not yet save projects, closing one loses it.

Winner: Otter.ai. Meetings and the written record

The verdict

Otter.ai is a meeting tool and Montaj is a video editor, so most people comparing them are really asking which one solves the problem they have. If the deliverable is a written record of a conversation , notes, a summary, something searchable afterwards , take Otter and stop reading. Montaj only overlaps at one point: it also produces a transcript, on your device, as a by-product of captioning a video.
