What counts as usage
Reading, writing and organising your project is never metered. Only calls that reach a model are.
| Action | Uses allowance |
|---|---|
| Creating, editing and organising notes, tasks and ideas | No |
| Reading a project through the REST API or the MCP server | No |
| Exporting or importing project JSON | No |
| Building a context pack for an agent | Only when a branch has to be summarised |
| Branch summaries, what-if scenarios, related-note search, generated content | Yes |
| Routing a quick note to the right branch | Yes |
Questions people actually ask
What happens when the allowance runs out?
AI features pause. Notes, tasks, the API and the MCP server keep working exactly as before, and the allowance resets monthly.
Is my content used to train models?
No. Your content is sent to a model provider only for an operation you or your agent starts, and we do not train on it.
Does Nibvine sell subscriptions or token top-ups?
No. Nibvine does not sell paid services, subscriptions or token top-ups. Model allowances limit shared resources; they are not a payment balance. If you choose to use your own provider key, any provider charges belong to your separate agreement with that provider.
Can I get my data out?
Any project or note branch exports to JSON from the product, and the REST API returns the same structures.
