They clearly changed their mind.

That "no longer developed" note is from September 2025.

These appear to be a sort of AI-driven re-evaluation.

I am a sort of engaged cynic about AI but I am happy to chalk this one up as a straightforward win for the machines.

(I'm also quite intrigued about the other blog post regarding an MCP for Simplenote — I love the idea of an LLM's knowledge-base being accessible in such an instantaneous way)

That is sad but not surprising. I think they always had a bit more trouble with its sync system than they would have wanted.

I loved Simplenote for the longest time but ultimately simple pragmatism switched me to Apple Notes after dalliances with several task management apps.
