Caption.Ed

Students and accessibility-conscious professionals who want desktop captions for any audio.

Caption.Ed sits on your desktop and captions whatever audio is playing, from Zoom calls to YouTube to in-room lectures via the mic. A personal accessibility tool, not a developer API. Acquired by Adept Mind in 2024 and still shipping updates.

Caption.Ed is a personal accessibility assistant that students and disabled professionals rely on for real-time captioning of whatever's playing on a desktop computer. The product sits in the menubar or system tray and captions any system audio: Zoom calls, YouTube videos, in-room lectures captured via the microphone, podcast episodes streaming in a browser tab. For users who need captions for accessibility reasons and want a single tool that works regardless of which app the audio is coming from, that breadth of input is the point. Lecture mode saves transcripts automatically, which makes Caption.Ed a useful note-taking tool for students who want a searchable record of class sessions alongside live captioning. UK English accuracy is consistently good, which reflects the company's UK roots and original university customer base. After the Adept Mind acquisition in 2024, the product has continued to ship updates and remains supported, though the long-term roadmap is uncertain enough that new users should check current development status before relying on it for critical workflows. The downsides are scope-related. It's a single-user desktop product with no team or organisation tier, no mobile version, and transcripts that are saved as plain text without the editing tooling you'd find in Otter or Descript. For its intended audience of individual accessibility users it's a real tool. For shipping captioned podcast content, it's the wrong fit.
