Jotr is a free Mac transcription app for audio and video files. It helps Mac users turn recordings into local transcripts, timestamped review sessions, notes, highlights, summaries, captions, and clean exports.

A key workflow is for video creators and editors. Finish editing your video first, then drop the final MP4 or MOV into Jotr. Jotr transcribes the spoken audio and exports timed subtitle files such as SRT or VTT, so the captions stay aligned with the final cut. This is useful for YouTube, social video, podcasts, courses, tutorials, interviews, and any video workflow where you want to edit the footage first and generate subtitles afterward.

Jotr also works for meetings, lectures, research sessions, client calls, podcasts, and interviews. You can review transcripts with timestamp-linked playback, search the text, correct lines, highlight key moments, add notes, and generate local AI summaries for faster understanding.

Key features:

  • Free Mac transcription for audio and video files
  • Local processing on Apple Silicon Macs
  • Timestamp-linked transcript review
  • SRT and VTT subtitle/caption export
  • TXT, Markdown, Word, notes, highlights, and summary exports
  • Local AI summaries for longer recordings
  • No account required to start
  • Recordings, transcripts, summaries, notes, and project files stay on your Mac

Jotr is designed for Apple Silicon Macs running macOS 15 or later.

Questions & Answers

As answered by people managing kdiff3 and Jotr.

What makes your product unique?

Jotr's answer:

Jotr is not just a raw transcription tool. It combines free Mac transcription, local Apple Silicon processing, timestamp-linked review, notes, highlights, local AI summaries, and export workflows in one desktop app.

A key difference is the creator workflow: video editors can finish the final cut first, then drop the exported video into Jotr and generate timed SRT or VTT subtitle files that align with the finished video. That makes it useful for YouTube videos, courses, tutorials, interviews, podcasts, and social clips.

Why should a person choose your product over its competitors?

Jotr's answer:

Choose Jotr if you want a Mac-native transcription workflow without sending every project into a cloud workspace. Jotr is built for people who already have audio or video files on their Mac and want to turn them into transcripts, captions, notes, summaries, and exports.

Compared with many web-based transcription tools, Jotr is more local-first and Mac-focused. Compared with simple transcript generators, Jotr adds timestamped review, highlights, notes, summaries, SRT/VTT subtitle export, and practical writing/editing exports.

How would you describe the primary audience of your product?

Jotr's answer:

Jotr is for Mac users who work with recordings: video creators, YouTubers, editors, podcasters, researchers, students, consultants, writers, meeting-heavy professionals, and anyone who needs transcripts, captions, summaries, notes, or subtitle files from audio and video.

It is especially useful for people who edit videos first and then need accurate, timed subtitle files for the final cut.

What's the story behind your product?

Jotr's answer:

Jotr was built around a simple problem: transcription is only useful when it becomes something you can review, edit, search, summarize, quote, publish, or export.

Many tools stop at a raw transcript. Jotr focuses on the work after transcription: listening back with timestamps, finding key moments, making notes, creating summaries, exporting captions, and turning recordings into usable writing, research, meeting, or video materials.

Which are the primary technologies used for building your product?

Jotr's answer:

Jotr is a native macOS desktop app built for Apple Silicon Macs. It uses local speech-to-text processing, local AI summary workflows, timestamp-linked playback, subtitle export formats such as SRT and VTT, and native macOS distribution through a notarized DMG.

The product is designed around local project files rather than a cloud workspace.

Jotr Reviews

  1. Jack R.
    ยท Producer at Vertex Media ยท
    The only local-first transcription workspace that actually respects your privacy and your wallet.โ€‹

    Iโ€™ve cycled through almost every major transcription SaaS, and Jotr is fundamentally different. While most focus on cloud subscriptions, Jotr is a dedicated "Review Workspace" that runs 100% locally on your Mac. For Creators:โ€‹ The free tier for recordings under 20 minutes is a lifesaver. I can drop a final cut into Jotr and get time-aligned SRT/VTT captions instantly without manual syncing. For Professionals:โ€‹ The Pro upgrade is where the real value is. Clicking any sentence to jump to that exact audio timestamp makes verification seamless. It replaces a clunky 3-app setup (player, doc, notes) with one professional interface. Perfect for journalists and researchers who can't upload sensitive data to the cloud.

    ๐Ÿ Competitors: Otter.ai, HappyScribe, Notta.ai, Rev.com, MacWhisper
    ๐Ÿ‘ Pros:    Local processing (privacy-first).|Generous free tier (under 20 mins, unlimited files).|Seamless "click-to-listen" synchronized timestamps.|One-time purchase (no monthly saas fees).
    ๐Ÿ‘Ž Cons:    No direct integration with notion/obsidian yet.|Requires apple silicon (m1/m2/m3) and macos 15+.|Resource-heavy during the initial ai transcription phase.
