Version 0.23.0
Released Oct 16, 2026 - 30.88 MBWorks with firefox 140.0 and laterWhat's Changed
* Faster OCR with GPU acceleration in Firefox. Text lines no longer wait on Firefox's slow GPU polling, and models warm up while you select an area
* Updated ONNX Runtime to 1.30.0 and switched to native WebGPU backend
* Translation provider pickers now show provider icons in the popup, settings, and on-page result panel
* Recognition progress now shows a static icon instead of a spinner, which could slow recognition on integrated GPUs in Chrome
* Fixed tapping an image in Firefox on Android, which could also activate the page underneath
Known issues
* In Firefox on Windows with GPU acceleration on, the first recognition can still take significant time because of slow shader compilation in Firefox. Turning off GPU acceleration in settings avoids it.Source code released under Mozilla Public License 2.0
