Does the job

Pretty happy overall. Automatic tag and link suggestions just works and works inside the familiar Obsidian environment. Limited to users already invested in Obsidian can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Compared a few options

Evaluated this against two competitors. Where it wins: context-aware answers from your vault and helps surface connections between ideas. On balance the feature set — especially note summarization and rewriting — justifies the 5 stars for our use case.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on template-based prompt workflows, and helps surface connections between ideas caught me off guard. still, I'd recommend giving it a real trial.

Solid for our team

We rolled this out across the team last quarter and works inside the familiar Obsidian environment. Support for multiple LLM providers fits neatly into how we already work, and note summarization and rewriting removed a step we used to do by hand. Requires an API key or subscription for full features, which is the main caveat, but it has held up under daily use.
