What is TRex?
TRex is an open-source macOS tool that captures text directly from the screen and copies it to the clipboard. The workflow is straightforward: select an area, OCR runs, text is ready. No detour via screenshots, no manual cleanup. TRex uses the native OCR capabilities of macOS and sits in the menu bar as a lightweight addition to an existing workflow.
Core features
- Extract text from any screen area by selection
- OCR based on the macOS Vision framework, no external services required
- Support for multilingual documents and content
- Capture code snippets from videos, tutorials or non-copyable interfaces
- Digitise handwritten notes or printed documents via screenshot
- Completely free, no account, no telemetry
Who is TRex for?
Developers who regularly retype code from tutorial videos or locked PDF previews will save meaningful time. Anyone working with international documents who needs text from foreign-language image files will also benefit from the multilingual support. The target audience is Mac power users who need OCR as an everyday tool, not an occasional feature.
The limitations are clear: users on Windows or Linux are out. And with low-resolution images or poor contrast, recognition produces errors. That is not specific to TRex; it is a basic condition of any image-based OCR.
Context & alternatives
TRex sits in the segment of screen OCR tools for macOS. TextSniper (paid, similar workflow) takes a comparable approach, as does the built-in Live Text feature introduced in macOS 13, which is only available in certain system contexts and does not cover freely selected screen areas. TRex fills that gap as a free alternative without restrictions to specific apps or windows. For anyone who needs a fast solution without licensing costs and works exclusively on a Mac, TRex is the more direct tool.
