What it does
Equalang Skill connects an agent to the Equalang translation service, which works on whole files: a PDF comes back as a PDF, a deck as a deck, with tables, images and formulas kept in place. SRT and VTT subtitles keep their timing, optionally with the source line above the translation. JPG, PNG, WebP and BMP images return with translated text. Audio and video become translated subtitles or a transcript in the spoken language as SRT, VTT, TXT or JSON. Short texts are translated in bulk in order, and one long text of up to 100,000 characters is split at sentences by the service. Cost can be asked before running, and PDF formulas are enabled with the separate `--optimize-math-formula` flag.
Who it is for. Translators, lawyers and researchers who need a translated document in the same format with tables and images in place.
Good fit when
- A PDF contract must be translated into Chinese with the layout unchanged.
- A 40-slide deck has to come out in Japanese and German.
- An interview in MP4 needs Korean subtitles with the original line above.
- Before sending a thesis you want to know the translation cost.
Not a fit when
- You need to translate a couple of paragraphs in chat: the agent alone is enough.
- The file may not go to an external service: translation runs through the Equalang cloud.
- There is no account and API key: the skill does not work without `EQUALANG_API_KEY`.
Example request
Translate ~/Documents/contract.pdf into Chinese, keeping the layout.Limitations
Translation is done by the Equalang cloud service for credits, and new accounts get free credits to try. The `EQUALANG_API_KEY` key is taken in the personal account and saved in `~/.config/equalang/.env`. PDF formula optimization is optional and costs an extra 10 credits per original page at the base rate. Files and text are sent to the service's server, so confidential material needs the operator terms. The skill works in any agent that supports Agent Skills and needs Python 3.8 or newer.
How to disable. Delete the `~/.claude/skills/equalang` directory or uninstall the plugin with `/plugin uninstall`. The key in `~/.config/equalang/.env` is deleted by hand.
