Yes, I'm not referring to accessibility in the formal sense. We created CoCalc's AI Assistant primarily to assist people in coding with Jupyter; it is largely a byproduct of that integration. We just happen to support LaTeX. It can be more efficient to generate templates because you can tailor them.

110

CoCalc @cocalc.bsky.social · 02/07/2025

The goal is to enable people to generate LaTeX formulas via prompt engineering (which is inherently more accessible than reading documentation on formatting). Not everyone knows how to write LaTeX, and it can be helpful to see examples. Why not generate an example with your own context?

110

CoCalc @cocalc.bsky.social · 02/07/2025

Personally, I think AI makes LaTeX and scientific computing more accessible. It’s simply another tool to be used in addition to the sort of tutorials you mention.

It can be useful for people learning how to use LaTeX (so you can look at an example with the context of your choice).

CoCalc @cocalc.bsky.social · 02/07/2025

The only thing I can mention is that you have to ask to do this in our LaTeX editor explicitly. Nothing is automatic.

100

CoCalc @cocalc.bsky.social · 02/07/2025

Haha, considering we all have math backgrounds over here, we're probably with you on that, but it's just an example to reduce time thinking about writing the actual LaTeX syntax.
