Fill columns with AI

Right-click a column header and pick Fill with AI… — describe what the column should contain and Manypages generates a value per row from the rest of that row's data. Empty cells only by default, so your hand-written values are never overwritten.

• Bring your own key: OpenAI, Anthropic, Google, or OpenRouter — stored encrypted, used only for your runs
• Up to 200 rows per run, with results applied as one undoable batch
• Prompts can reference any column in the row

Improvements

• CSV import and AI fill share the same ops pipeline, so both show up cleanly in the sheet's change history.
