LaTeX Mathematics supports inline and display equations, from simple formulas to multi-line systems and matrices.

Does Telescopo collect any data or have any tracking?
No. Telescopo has no analytics, telemetry, or tracking in the app. Your documents stay on your Mac unless you choose to save them somewhere like iCloud Drive. The AI Assistant is designed for local, on-device Apple Intelligence workflows on supported Macs.
Can Telescopo keep up with AI-written or externally updated Markdown files?
