You would not let a contractor renovate your store from behind a curtain. That is what most AI-for-Shopify tools ask: hand over API access, wait, see what the storefront looks like after. Antigravity is built the other way around. It is Google's agent-first IDE, and its whole premise is that you watch the agent work: the plan appears in front of you, the edits happen in files you can open, and nothing is out of sight at any point.
Scratch gives that agent your catalog in the form it needs, and adds the gate the storefront needs. Your products come down as a folder of files on your laptop, one per record. The Antigravity agent does 99% of the work in that workspace while you watch. The last 1% is yours: every change comes back in Scratch as a word-level diff, you approve what ships, and only those records go back to Shopify. Prices, variants, and inventory stay locked throughout.
How it works
- Scratch pulls your catalog into files. Products, articles, blogs, and pages land in a folder on your laptop, one file per record, normalized and ready to edit.
- Antigravity's agent works the folder. Open the Scratch folder as a workspace and describe the job. Rewrite every product description in our voice, keep each under 300 words, do not touch the specs table. The agent plans the pass in front of you, then edits file by file. You can open any file mid-run and read what it is doing. It edits the files, never the live store.
- You review every diff and publish. Scratch shows each change beside the original, word by word. Approve what ships, and Scratch sends only those records back to Shopify. What you skip never leaves your laptop.
What people use it for
The catalog work you want to supervise, not delegate blind:
- Rewrite every product description in one voice, watching the pass as it moves.
- Dedupe the supplier boilerplate that fifty products share word for word.
- Backfill SEO titles and meta descriptions, each unique, each under the cap.
- Normalize vendor, type, and tags so collections and filters behave.
- Clean up articles and pages in the same workspace as the products they link to.
Run ten products first, watching the whole way. Scale up when the agent has earned it.
Why not an MCP server?
A Shopify MCP server wires an agent straight to your live store. Even when the agent works in plain sight, its writes do not: they land on the storefront as they happen, and watching a mistake occur is not the same as being able to stop it.
Scratch separates seeing from shipping. The agent gets full read and write against a local copy, you watch as much or as little as you like, and the publish step waits for your approval either way, record by record. Visibility is Antigravity's half. Control is yours.
What Antigravity edits in Shopify
Editable fields:
- Product titles, descriptions (HTML), and handles
- Vendor, type, and tags
- Product SEO title and meta description
- Articles, blogs, and pages
Stays locked:
Prices, variants, inventory, and metafields are locked at the connector level. The agent cannot write them back even if it tries, and length and taxonomy validators flag problems right on the diff. The full field list lives on Scratch for Shopify.
Questions people ask
What is Antigravity?
Google's agent-first IDE: an editor built around agents that act on a workspace of files, with the agent's plan and progress visible as it works. You sign in with your own Google account. Scratch holds no Antigravity credentials and runs no model.
Is this an MCP server or a Shopify app?
Neither. Both hand the agent a live line to your store with the write built in. With Scratch, the agent edits a local copy, and publishing is a separate step you approve, one record at a time.
Can it touch my prices or inventory?
No. Prices, variants, inventory, and metafields are locked at the connector level, so a stray edit to them cannot write back.
Can I roll back a published change?
Yes. Every published record is reversible from Scratch, per row. The original sits next to the rewrite until you decide which one stays.
Can it handle the whole catalog?
Yes, that is the use case. The Scratch folder holds every record, and the agent works through it file by file while you watch. Start with ten products to settle the prompt, then run the rest.
Do I need to be a developer?
Antigravity is an IDE, so it helps to be comfortable in one, but the loop itself is read and click: read the plan, read the diffs, approve. If an editor is not your surface, the Claude desktop app runs the same Scratch loop as a plain desktop app.
