# Store data on demand

TendBase does not save every conversation automatically. Store information when the user asks you to remember, track, organize, import, or maintain it.

Use structured objects for items such as tasks, recipes, appointments, projects, reports, and quarterly results. Use documents when the source material matters as a whole. Record source and time provenance when available.

Before the first write, call `tendbase_help`. Prefer idempotent writes. Return the TendBase receipt so the user can tell what changed.
