A small Chrome and Edge side-panel extension that reads only text you explicitly select and runs DistilBERT locally.
Manual installation
This package is not yet signed or listed in a browser store. Developer mode lets you inspect and test the exact files while the product is still in preview.
Download the ZIP above, then extract the runanyai-tone-reader-extension folder.
Enter chrome://extensions in Chrome or edge://extensions in Edge.
Use the Developer mode switch on the extensions page.
Select the unzipped extension folder—not the ZIP file itself.
Open the browser’s extensions menu and pin the Local Tone Reader for quick access.
Highlight English text on a normal web page, click the extension icon, then choose Use selected text.
First run
The 5.7 MB ZIP contains the interface and browser AI runtime. The quantized DistilBERT model is approximately 70 MB and downloads from Hugging Face only when you start the first analysis. Chrome can cache those files for reuse.

Preview boundaries
Manual updates. Download a future package again when the preview version changes.
English sentiment only. Positive/negative classification cannot reliably capture sarcasm, mixed emotion, intent, or truth.
Restricted pages. Chrome settings, the Web Store, PDF viewers, and some protected pages may refuse selection access.
Inspect before trusting. Keep Developer mode limited to extensions you understand and remove the preview when you no longer need it.
