AI planner & to-do API — smart tasks and habit coaching
The API plans a schedule, breaks goals into tasks and coaches habits over time rather than returning a static list.
Productivity apps use it as the reasoning layer behind their own task model.

Spelling & grammar check, summariser and text compare
Three writing tools behind one API: spelling and grammar correction, summarisation of long documents, and a comparison that highlights what changed between two versions and how similar they are.
Editors, CMS platforms and document tools use it without wiring three separate services.
