subtitle.im pricing, free plan and limits

Last updated: 2026-10-25

subtitle.im is a desktop Chrome extension that gives YouTube viewers 3 caption modes: follow YouTube, auto-open or auto-close. It also reads sampled video frames with on-device OCR to find burned-in subtitles, then can close the duplicate caption track. It manages existing captions only and generates or translates none.

About subtitle.im

subtitle.im is a Chrome extension for desktop YouTube that decides whether the captions YouTube already offers are on or off, and what to do when they overlap subtitles burned into the video picture. The vendor's terms and privacy policy name the operator only as subtitle.im, with a support email and a public GitHub repository that holds feedback and bug reports but no source code. None of the pages read for this record names a company, founder or funding figure, so none is recorded here. That repository was created on 12 October 2026 and nothing else on the site shows a longer track record, so treat it as a very new product.

The mechanism has two parts. Caption control sets a global mode: follow YouTube, auto-open an existing track, or auto-close it. Duplicate handling samples frames from the video and runs optical character recognition (OCR, software that reads text out of images) inside the browser to look for burned-in subtitles. When it finds them next to a YouTube caption track it can close that track automatically, and a separate setting for subtitles in a different language chooses between closing, asking first and keeping the track. Pressing CC or the C key always wins for the current viewing, and a Restore captions button reverses a closure made by mistake. The burned-in text itself stays on screen.

It suits people who watch subtitled channels, such as creators who hard-code subtitles into the video while YouTube also shows its own caption track, and people who want captions permanently on or permanently off without touching CC on every video. Pro adds per-channel and per-video rules and a memory of closures you have confirmed.

Free use needs no account and the allowance lives in the extension; signing in with Google, GitHub or an email code is only needed to buy or restore Pro. The pricing notes below carry the prices and refund windows.

If you need captions created or translated rather than managed, the nearest records are VEED for browser editing with auto-subtitles, Zeemo for captioning and subtitle translation, CapCut for editing with auto-captions and Descript for transcript-based editing, with Vmaker adding subtitles in a browser editor and OpusClip cutting long recordings into short clips. The guide to AI dubbing and video translation tools covers the translation side, and AI accessibility tools or the wider AI video tools section list more products. For other YouTube tooling, the guides to AI tools for YouTube research, summarizing YouTube videos and creating YouTube videos cover the creator and research side, and the industry verticals group shows where accessibility tools sit in the directory.

Key Features

• Three caption modes: Follow YouTube, Auto-open or Auto-close sets how existing caption tracks behave on every video, and Follow stops the extension from opening captions on its own.
• On-device subtitle detection: Frame sampling and OCR run in the browser, so video frames and subtitle text are not uploaded to a server for detection.
• Duplicate caption handling: When burned-in subtitles and a YouTube caption track overlap it can close the track automatically, and a separate setting decides whether to close, ask first or keep it when the two languages differ.
• Manual override and restore: Pressing CC or the C key wins for the current viewing only and never saves a rule, while Restore captions undoes a closure made by mistake.
• Channel and video rules (Pro): Always enable or Always disable captions can be set for a channel or a single video, with priority going to manual CC, then the video, the channel and finally global settings.
• Remembered closures (Pro): The Remember confirmed closes option stores the closures you approve and is listed as a Pro feature.
• Account-free trial: The free allowance lives in the extension and needs no email, and only a successful caption closure counts against it.

Pros

• Trying it costs no sign-up, so the cheapest test is installing it and watching one subtitled channel.
• Only a manual click on Upload sends diagnostic logs to the vendor, and the policy says those logs exclude subtitle text and video frames.
• Lifetime billing pays back against annual billing by the second year, a clear choice for anyone who expects to keep using it.
• The refund promise asks for no proof of non-use and no viewing history.

Cons

• Works only on YouTube in desktop Chrome; other sites, mobile browsers and local video files are outside its scope today.
• Detection is probabilistic: the vendor says misses and false positives occur, and low resolution, unusual placement or complex lettering lower accuracy.
• It cannot remove burned-in subtitles or generate or translate captions, so it solves only the overlap problem.
• No user count, store rating or independent review could be read for this record, so its reliability over time is unverified.
