Prism

Prism is a lesser-known tool for people who write scientific papers in LaTeX and are tired of paying for Overleaf or wrestling with a local install. It's a free, cloud-based LaTeX editor from OpenAI with AI assistance built straight into the writing flow.

What makes it different

The AI has access to your whole document: equations, references, figures and context. It gives suggestions based on what you're actually writing, not generic LaTeX answers. You can take a photo of a handwritten equation and let Prism convert it to LaTeX.
