Bulk AI content sheets, grounded and checked

Proofsource Sheets are spreadsheet grids where agent columns draft content for many pages at once. Start from your sitemap with an FAQ agent column, run a cell, row, column or the whole sheet, watch drafts pass a quality check, see the inputs and stored page text each cell was grounded in, then publish finished drafts to your site after you confirm, with rollback.

What is an AI content sheet?

An AI content sheet is a spreadsheet where some columns are filled by AI agents instead of people. Each row is a page or item; an agent column reads the row's inputs and writes a draft, such as an FAQ block or a clearer product answer. It is how teams make the same improvement across hundreds of pages without losing track.

Proofsource Sheets ground every draft in stored page text, so a cell can show exactly what it was based on. Bulk runs show progress and how many drafts passed the quality check. Formula columns help with checks like length. When a row is ready, you confirm and it publishes to your site, with rollback if you change your mind.

How it works

Spreadsheet grids where agent columns draft content for many pages at once, grounded in your stored page text, with proof per row.

  1. Start a sheet

    From your sitemap, an import or the draft row.

  2. Add agent columns

    Pick an agent such as FAQ, plus formula and typed columns.

  3. Run

    Run one cell, a row, a column or the whole sheet.

  4. Check and prove

    Drafts pass a quality check; each cell shows its sources.

  5. Publish

    Confirm a row and it goes live, with rollback.
