An AI subtitle generator that leaves you the .srt file on your PC without uploading the video: install AppGrabbit, open Download › Subtitles with AI, paste the link or drop your video and click Get subtitles. Out come the .srt and the .vtt timed word by word, plus a clean .txt, in the Subtitles folder. That .srt goes straight into Premiere, DaVinci Resolve, CapCut or YouTube. 1 credit · 5 free a month
What a subtitle generator should give you: the file
Many web “generators” show you the subtitles on screen and, to download the .srt, ask for an account or payment. The file is what matters: with it you upload closed captions to YouTube (and the video becomes accessible), drop them as a track into your editor with the timing already set, or fix them in a minute in Notepad. Here the .srt comes with the credit, no account.
Why word-level timing matters
A normal .srt carries one time per sentence. AppGrabbit's comes from Whisper (whisper.cpp) running on your PC with the timing of every word: that is why the Center style can light up the word being spoken, and why, if you cut the video in your editor, the subtitles still line up. Blocks are built the way the trade does: two lines of up to 42 characters, breaks on silences and at the end of each sentence.
The .srt you get, with an example
- Block — number, in and out time with milliseconds, and the text: “3 · 00:00:07,420 → 00:00:09,880 · and still, in a minute, I have the whole text”.
- Where it goes — the Subtitles folder inside your downloads folder, and the Library.
- To upload to YouTube — YouTube Studio › Subtitles › Upload file: with timing.
- For your editor — Premiere (File › Import), DaVinci (File › Import › Subtitle), CapCut (Text › Local subtitles).

Step by step
- 1Install AppGrabbit for Windows — Download the free installer (everything included). Windows will say it protected your PC because the installer is not code-signed: click More info, then Run anyway.
- 2Open Download › Subtitles with AI — Paste the video link (YouTube, TikTok, Instagram, Facebook, X, Twitch) or drop your file (mp4, mkv, mov, webm). From the Library, any video has “Subtitles with AI” in its ⋯ menu.
- 3Click “Get subtitles” (1 credit) — The first time, the app gets the AI engine ready on your PC (a one-time download) and carries on by itself. Out come the .srt, the .vtt and the .txt in the Subtitles folder, timed word by word.
- 4Open the Subtitles folder — There you have the .srt (for YouTube, Premiere, DaVinci, CapCut and any player), the .vtt (for the web) and the clean .txt. They are in the Library too.
- 5Burn them in if you want — Pick the style on a real frame (free) and “Make the video” (Pro) leaves you the subtitled MP4. But the .srt is already yours from step 3.
Frequently asked questions

Yes, and ours are better for editing: YouTube's come per sentence; the app's carry the timing of every word, which is what a word-by-word style needs.
Getting the subtitles (.srt, .vtt and .txt) costs 1 credit; Free comes with 5 a month. Previewing them on your video, in the three styles, is free. Burning them in (“Make the video”) is for Pro (USD 8.99 a month) or the 7-day pass (USD 3.99, no renewal). There is never a watermark, not even on Free.
The spoken one; the engine detects it and you can pin it before starting. It does not translate: a video in another language is a different job.
The app tells you and gives the credit back. A music-only video gets no made-up text.
Nothing. The video stays on your PC: the AI engine (Whisper, whisper.cpp) runs on your computer, on your NVIDIA card if you have one or on the CPU if not, and FFmpeg burns the subtitles right there.
