Duetoday demo
See the Duetoday subtitle workflow
Duetoday starts from the transcript layer, then keeps the same source ready for notes, summaries, flashcards, and study follow-up after the subtitle file is exported.
Accessibility Tools
Add Subtitles to Video
Upload a clip, generate timed subtitle files, and keep the transcript ready for the next Duetoday workflow instead of bouncing between separate captioning and note apps.

How it works
Use the tool first, then keep the output alive.
Upload the source clip
Start with a lecture recording, webinar, explainer, or accessibility pass from a draft video.
Generate timed subtitle cues
Duetoday transcribes the audio track, groups it into readable subtitle segments, and prepares both SRT and VTT output.
Export and keep moving
Download the subtitle format you need, then reuse the transcript inside Duetoday instead of rebuilding the content somewhere else.
Who is this for
Add Subtitles to Video works best when the source already exists.
- Creators shipping tutorials, explainers, and training clips that need readable subtitles quickly.
- Students or educators publishing class clips and wanting a clean accessibility layer before sharing.
- Teams that need caption exports plus a usable transcript they can keep working from afterward.
Benefits of Add Subtitles to Video
Get a caption file without leaving the browser
The first value is speed: upload the media, get a subtitle draft, and avoid a slower editor-first workflow for the initial pass.
Keep the transcript useful after export
The same transcript is ready for notes, summaries, and follow-up study inside Duetoday instead of stopping at caption delivery.
Switch between standard export formats fast
SRT and VTT are both available, so the same transcription pass can fit the destination platform you are publishing to.
Comparison
Duetoday vs a basic subtitle generator
Most subtitle tools stop at the caption file. Duetoday keeps the source transcript alive for the rest of the workflow too.
| Capability | Duetoday | Typical tool stack |
|---|---|---|
| Timed subtitle export | Generate SRT and VTT from the same uploaded source in one place. | Often focused on one export format or an editor-first workflow. |
| Speaker-aware transcript context | Keep transcript structure and speaker labeling available alongside the subtitle file. | Speaker context is often flattened or lost during the first pass. |
| Next-step workflow after captions | Move the same transcript into Duetoday notes, summaries, and revision flows. | Usually ends once the subtitle file is downloaded. |
| Browser-first accessibility preview | Good for a fast first accessibility layer without opening a separate editing stack. | Can require more manual setup before the first usable caption draft appears. |
Use cases
Where this free tool usually makes the most sense.
Captioning lecture clips before posting them to a class hub
Create subtitle files first, then keep the same transcript around for revision notes or student support material.
Adding readable subtitles to async onboarding videos
Generate the first caption layer quickly, then hand the export off to the publishing or LMS workflow.
Producing a transcript-backed accessibility draft for social and web video
Use the subtitle file for publishing while still retaining the plain transcript for documentation or repurposing.
Frequently asked questions
What people usually want to know before they use Add Subtitles to Video.
What does this Add Subtitles to Video page generate?
It generates timed subtitle text from an uploaded media file and gives you browser-ready SRT or VTT output, plus the transcript behind it.
Can I keep speaker labels in the subtitle export?
Yes. When speaker labels help readability, you can keep them attached to the cue text instead of flattening everything into one undifferentiated block.
Does it change the video file itself?
No. This page generates subtitle and transcript output. You can then upload the exported file to the video platform or editor that will burn in or attach the subtitles.
Why use this instead of a dedicated caption editor first?
Because the first bottleneck is usually getting to a usable subtitle draft. Duetoday is strongest at that fast first pass plus the follow-up workflow built on the same transcript.
What is the best source material for this page?
Short, clear audio/video clips work best. Very noisy recordings or clips with multiple overlapping speakers will need more cleanup after the initial draft.

Student stories
Transcript-first workflows get more useful when the next step is already built in.
Students and teams stick with Duetoday when the source can move from transcript into something more useful immediately.
I used to miss so much because I was trying to write notes and listen at the same time. Now I just record and I know every word is captured.
The flashcards it generates from my recordings are scarily accurate. It picks out exactly the kind of things that end up on exams.
Duetoday catches everything and then the AI tells me what my professor actually said about the topic. Not generic web answers. My real lecture.
