Formulens

Turn equation screenshots into LaTeX without typing them out.

Formulens runs locally on an NVIDIA GPU. Start its daemon, use a keyboard shortcut to select an equation on COSMIC, and paste the recognized LaTeX into your notes when the completion notification appears. The daemon keeps the model loaded between requests.

You can also recognize an existing image. Temporary screenshots are deleted once processing ends; files supplied to recognize are preserved.

Get started

1. Install Formulens with Python 3.14 and CUDA support.
2. Start the daemon and configure a capture shortcut.
3. Choose a model and configure preferences.

PaddleOCR-VL is the default model; GOT-OCR is also available. Native capture and daemon support currently target Linux. Clipboard integration uses Pyperclip. Recognition requires NVIDIA CUDA; there is no CPU fallback.
