Same app. Same prompt. Spreadsheets swapped for tables.

What the backend has to do

Four things a spreadsheet can’t, and an app for a team needs.

Fast

Made for AI use. The app asks for the rows it needs and gets only those, filtered, sorted, and paged on the server.

Secure

Row-level security. People and agents see and change only the rows they’re allowed to.

Compliant

Every change is logged with who, what, and when. Full revision history, one-click revert.

Multi-user

Row-level saves. Six people can edit at once and nobody overwrites anyone else.

Not just tables

Your app's documents live here too.

Specs, runbooks, policies, meeting notes. Markdown files sit in folders next to your tables, with the same guarantees as rows.

  • Organized. Folders and subfolders, like a shared drive.
  • Indexed. Every file is embedded on upload and ready to search.
  • Searched by meaning. Claude asks a question and gets the passage, not the whole file.
  • Versioned. Every edit is a revision. Revert any of them.
  • Audited. Who changed what, and when, in the same log as your tables.

If you built one

It worked for you. Then the team tried it.

Takes 20 seconds to open. Someone edits and it doesn't stick. Nobody knows who changed the numbers. Point Claude at TableThis once and the same app loads instantly, saves every edit, and shows who did what.

If you're rolling out Claude

Every team is about to build apps. Decide now where the data lands.

Left alone, it lands in spreadsheets on personal drives, with agents writing to them unrecorded. With TableThis it lands in a workspace you administer: permissions for people and agents, full audit log, one-click revert.

The obvious question

Why not just put a spreadsheet in a shared folder?

Because a spreadsheet is one file, and an app needs rows. Every symptom people hit comes from that one gap.

Opening the app Spreadsheet Claude downloads and parses the whole file every time. 20 to 30 seconds on a real sheet. TableThis Claude asks for the rows it needs and gets only those. Milliseconds.
Saving a change Spreadsheet A Cowork app can't write back to a Sheet, Excel file, or shared-folder CSV. Edits stay in one person's browser or get re-uploaded by hand. TableThis The app saves in one call. Everyone with access sees it on their next open.
Two people at once Spreadsheet Last save wins. The other person's work is gone, silently. TableThis Row-level saves. Both edits land; nothing is overwritten.
Finding one record Spreadsheet Claude reads every row to find one. Slow, and it costs tokens. TableThis A query. One row in, one row out.
Who changed what Spreadsheet File version history tells you the file changed. Not which cell, or whether a person or an agent did it. TableThis Every change names the row, the field, the actor, and the time. One click reverts it.
Letting an agent write Spreadsheet Folder permissions are all or nothing. An agent with the link can rewrite the whole file. TableThis Agents get their own access level: read, propose, or write. Proposals wait for a human.

And why not Supabase or Neon? They're built for apps on the internet. Yours is for the people down the hall.

Supabase, Neon, Postgres

  • A developer sets up schema, keys, and auth for every team.
  • New tables can default to public.
  • No row history, approvals, or undo. Agents write straight through.
  • Documents live somewhere else.

TableThis

  • Claude creates the table. No developer in the loop.
  • Private to your workspace. Invite by email or SSO.
  • Every change attributed, reviewable, reversible.
  • Markdown docs next to your tables. Claude searches them by meaning.
