Mistral OCR for Chrome

About

Transcribe documents and images directly from Chrome using Mistral OCR.

Chrome Mistral OCR lets you process PDFs, images, documents, Google Docs, Google Slides, and Google Sheets from the extension popup. You can preview the OCR result, edit the extracted Markdown, copy the content, export it, save images, and generate a PDF from the rendered preview.

🔍 Main features

OCR powered by mistral-ocr-latest.

Support for two API keys, each with a custom label, so you can quickly switch between accounts or profiles.

Optional image extraction from processed files.

Export extracted images as a ZIP file or as separate files.

Preview and edit transcriptions with a Markdown editor, rendered preview, optional autosave, copy button, Markdown export, and PDF export.

Highlight low-confidence OCR words to help you review uncertain text more easily.

Save transcriptions locally and search them by name, URL, SHA, or file type.

Support for Google Docs, Google Slides, and Google Sheets.

Browser-language localization with English fallback.

📄 Supported formats

Primarily supports PDF documents rendered individually in Chrome, as well as Google Docs, Google Slides, and Google Sheets documents.

Additionally, the extension works with any image that Chrome renders individually in a new tab.

⚙️ First use

Create an API key in the Mistral Console:

Then open the extension, click Configure, paste your key into API key 1, and click Save.

You can also configure API key 2 if you want to switch between two accounts or usage profiles.

After setup, open a compatible document, image, or file in Chrome, open the Mistral OCR extension, choose whether to download images, and click Transcribe (OCR).

If a transcription already exists for the current URL, the main button will change to Overwrite.

🛠 Troubleshooting

If OCR does not start, make sure an API key is saved and that the active Chrome tab contains a compatible resource.

If a background OCR job is already running, wait for it to finish or cancel it before starting a new one.

If local files do not work, open chrome://extensions, go to this extension’s details, and enable Allow access to file URLs.
