> Atoi is happiest when files are legible, purposeful, and attached with a clear question in mind.

## Common file shapes

| Kind | Examples | Best use in Atoi |
| --- | --- | --- |
| Text and code | Notes, markdown, source files | Summaries, explanations, edits, comparisons |
| Documents | Policies, specs, exported reports | Orientation, extraction, question answering |
| Images | Screenshots, diagrams, visuals | Inspection, comparison, reference |
| Project material | Working files tied to a conversation | Longer-running context and continuity |

## Storage posture

Storage is there to make continuing work easier, not to encourage dumping everything into the product.

Atoi generally works best when you keep only the files that are active, recurring, or genuinely worth revisiting.
