What it does
Mark an area of the screen and Translumo reads whatever text appears there, translates it and draws the result on top - useful for games without localisation and for apps where text cannot be selected. It runs several OCR engines at once and uses a machine-learning model to pick the most likely reading. Windows only: unzip the release and run Translumo.exe, no command line involved. Apache-2.0 licensed.
