Pause on the word you did not catch, and see it in context
Stremio Reverso is for learning English from what you already watch. Rest the cursor on a subtitle and Stremio pauses. Every word becomes hoverable and opens its Reverso Context page, with translations and real example sentences; drag across a few words to translate a phrase, or translate the whole line. Move away and the film carries on. It runs on Windows, reads subtitles with the OCR built into Windows, and uses your own Reverso account. Free and MIT-licensed.
The challenge
Watching in a language you are learning means a word you miss every minute. Stopping to look it up means finding the pause button, typing the word into a phone and losing the scene — so most people let it go by.
The approach
Stremio Reverso keeps reading the subtitle area while Stremio plays. The moment your cursor touches a line, it pauses, lays a hoverable box over each word and opens the Reverso Context page for the word under the cursor — translations and example sentences, in your own Reverso account. Move off the subtitle and playback resumes.
Build from GitHub with the .NET 8 SDK; it sits in the tray. Sign in to Reverso once.
Play anything in the Stremio desktop app. The app quietly reads the subtitle area.
The video pauses. Hover a word, select a phrase, or hover ⇄ for the whole line.
Take the cursor off the subtitle and the film carries on where it stopped.
The subtitle area is read every 250 ms while Stremio plays, so resting the cursor on a line pauses straight away. Move off it and playback resumes — only if the app was the one that paused.
Once paused, each word gets an invisible box. Hover one and a popup shows its Reverso Context page: the translations and real example sentences, not one dictionary line.
Click a word or drag across several to translate the selection — up to three words go to Reverso Context, longer ones to full translation. The ⇄ after a line translates all of it.
The popup is a real browser showing reverso.net. Sign in once from the tray, Premium included, and every lookup uses your account.
It never takes focus from Stremio. While paused, an invisible shield keeps Stremio from seeing the mouse, so its controls stay hidden and the subtitle does not jump.
Screen capture and OCR run on your PC, with the OCR engine that ships with Windows. The code is MIT-licensed on GitHub, with unit tests for every pause and resume decision.
Language learners
Keep English subtitles on and look up only the words you actually miss, in the sentence they were used in.
Evening watchers
The pause, the lookup and the resume are one movement of the mouse, so the scene is still there when you are done.
Intermediate learners
Drag across “give up” or “look forward to” and Reverso Context shows how the whole phrase is used, not three separate words.
What we did
Yes, and open source under the MIT license. Reverso’s own free and Premium plans apply to what you look up there.
It is built for the Stremio desktop app (version 5) on Windows. It finds Stremio’s window and reads the subtitles off the screen.
English subtitles, translated to Ukrainian. The pair is one setting in the code.
There is no installer yet. Clone the GitHub repository and run it with the .NET 8 SDK; the README has the two commands and a publish command for a standalone exe.
Screen capture and OCR stay on your PC. Only the words you look up leave it, loaded from Reverso in the embedded browser, and your Reverso login is stored locally.
