The product has al lot of potential to be a second brain, a vary wide brain, to do (internet) research en writing on things, but is is not an finished product yet. It misses an app, but that is coming and the extension could use some extra possibilities. The Ai is on par with what people can expect and the possibility to choose between LLM's is a good get. I do not know if there is some additional prompting is going on in the backend, but there is a clear understanding of language in reading notes and well given responses.

Like with any Ai it is important to know how to ask the right questions. To me the interface is a bit more for alpha minded people than beta's like me that likes Fabric a that more, but that has lesser Ai possibilities. It works just as good in English to me as it does on Dutch text and responses. It can give good advice on writings of my own to improve writing skills and artikels.
