What the alternative costsManual subtitling in a video editor is the alternative; no price is stated in the supplied sources.
If this goes wrong: a name or phrase is captioned incorrectly, and you fix it before exporting or publishing the video.

The route this page recommends
A person who owns the outcome does this end to end, worth it when the failure is dear.

Second choiceA chat interface, no skill needed, and roughly 15 minutes until you can act on the result.
How to actually do it
- Open VEED or another video editor with AI subtitles, and upload the original video file.
- Set the spoken language to [LANGUAGE], then ask the tool to generate subtitles from the audio without paraphrasing.
- Paste the supplied prompt into the tool's instruction or caption settings, choosing [CAPTION STYLE] and the required export format.
- Read the generated transcript while listening to the video, and correct names, places, numbers, slang and any words marked as unclear.
- Watch the entire captioned video with the sound lowered, checking that each caption appears with the speech and does not cover faces, signs or existing text.
- Export the corrected video, then open the exported file on the device where you will share it and check the captions still display correctly.
Prompt
Add accurate subtitles to the attached video. Transcribe only what is spoken and do not invent or paraphrase words. Use [LANGUAGE] unless the speech clearly uses another language. Keep captions easy to read, split them at natural pauses, and avoid covering important faces, signs or on-screen text. Mark important non-speech sounds in square brackets, such as [music] or [door closes], only when they help a viewer understand the scene. Preserve names, places and technical terms exactly where the audio supports them. First produce a timestamped transcript for checking, then create the captioned video in [CAPTION STYLE] and export it as [MP4 OR OTHER FORMAT]. Flag any word or section that is unclear instead of guessing.
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

The distant third
What it gets wrong
- AI cannot reliably identify an unclear word when the audio is muffled, overlapped or heavily accented, so it may guess.
- AI cannot know whether a person's name, local place name or specialist term is correct unless you check it against the audio or your own source.
- AI cannot decide the caption style that best matches the mood, audience or visual identity of your video.
- AI does not take responsibility for an inaccurate caption or for exposing private speech in a video you upload.
Even on a YES, the friction has a name: verification cost and taste.

FAQ
- Can AI automatically subtitle a video?
- Yes. AI can transcribe the speech, time the captions and add them to the video. You still need to watch the result because names, accents, overlapping speech and background noise can produce errors.
- What is the best AI tool for adding subtitles to a video?
- VEED is a suitable purpose-built option because it is a browser video editor with AI subtitles. Descript is another option when you want to edit the video through its AI transcript.
- Can AI add subtitles to a video for free?
- A free chatbot or video tool may help create a transcript, but the supplied information does not establish which subtitle exports are free. Check the tool's current export terms before uploading the video.
- How do I make sure AI subtitles are correct?
- Play the whole captioned video while comparing every caption with the spoken audio. Pay particular attention to names, numbers, places, technical terms and sections where people speak over one another.
