Eloi Delmonico,
I have already recommended NotionForms to many who work with Notion because NotionForms greatly improves the workflow, and users easily submit their info, data, etc.
I consider NotionForms our best tool to accompany us when we need to fill in our databases.
Trying to connect a Notion database with an exterior service can be long and difficult sometimes (mapping data, for example).
What we like is that it is almost "plug and play". You create a database, and then the form is already connected. This is really easy to use.
Using a form instead of manually writing every database cell is much easier for the users. So users make fewer mistakes and have more fun. 😃
