Local subtitle burn
One conversation, complete workflow
From local video to finished subtitles
The agent coordinates SRTGen’s localization tools while keeping you in control of local commands and final output.
Translate timed captions
Create additional language tracks while preserving the original subtitle timing.
Control readability
Set word and character limits, punctuation, speech-gap behavior, and sentence splitting.
Use your style presets
Choose built-in or saved presets, then customize typography, color, position, and karaoke.
Export the right format
Ask for SRT, VTT, ASS, TXT, or JSON and receive a file ready for your next tool.
Create a subtitled video
Prepare a watermark-free local render, or use cloud rendering when local tools are unavailable.
Built-in visual workspace
Fine-tune anything manually.
Your agent gets you to a finished draft fast. When a caption needs a human touch, open the project in SRTGen to edit the words, adjust timing, switch style presets, and preview every change.
- Edit caption text and line breaks
- Adjust timing on the visual timeline
- Apply built-in or saved style presets
How it works
Set it up once. Then just ask.
Connect SRTGen
Add
https://www.srtgen.com/api/mcp as a remote MCP server, then sign in or use your SRTGen API key.Give your agent a prompt
Include the local file path and the outcome you want. Your agent plans the correct upload, transcription, translation, style, and export steps.
Review the result
Open the generated SRTGen project, download subtitle files, or inspect the locally burned, watermark-free video.
Large video support
Move the audio, not the 2 GB video
For videos over 200 MB, a locally capable agent uses FFmpeg to extract a 192 kbps MP3. Only the audio goes to SRTGen for transcription. The original video remains on your machine and is reused for the final render.
- Resumable upload fallback when local commands are unavailable
- Original video stays local in the recommended workflow
- Styled ASS export for precise, stable subtitle rendering
- Local burn uses the same static subtitle rendering path—without a watermark

Frequently asked questions
Which AI agents work with SRTGen?+
SRTGen uses the open Model Context Protocol (MCP). It works with MCP-compatible clients that support remote HTTP servers and authentication, including compatible versions of Claude and Codex.
Is AI agent localization available on the free plan?+
No. Connecting SRTGen to an AI agent requires an active Starter, Pro, or Business subscription. Usage-based processing still consumes the credits included with the selected plan.
Can an agent process a video larger than 200 MB?+
Yes. When the agent can run local commands, SRTGen tells it to extract a compact MP3 with FFmpeg and upload only that audio for transcription. The original video stays on your computer for the final burn.
Can I control punctuation and subtitle line length?+
Yes. Agent tools expose project settings such as punctuation display and maximum words per line, as well as language, export format, and burn style choices.
What happens if the request cannot be completed?+
The agent receives structured, actionable errors for invalid authentication, missing users or projects, insufficient credits, unsupported requests, expired uploads, and processing failures.
