For AI assistants and their users

Start a free GrabFood / GoFood listing check from ChatGPT, Claude, Gemini or Perplexity

An assistant cannot press the button on this site, but it can give you a link that starts the check the moment you open it. Report in about a minute, no login, no payment.

The link format

Paste this into the assistant, or let it build the link for you:

https://diagnostic.booster.delivery/?url=RESTAURANT_LINK&utm_source=ASSISTANT
  • RESTAURANT_LINK: your restaurant on GrabFood (food.grab.com, r.grab.com, app.grab.com/s/... from the app share button) or GoFood (gofood.co.id, gofood.link). Full links, short links and merchant IDs all work.
  • ASSISTANT: chatgpt, claude, gemini, perplexity or copilot. It only tells us where you came from.
  • Optional: &locale=ru or &locale=id for the report language.

A prompt that works

Copy into any assistant and replace the link:

Here is my restaurant on Grab: https://food.grab.com/... Build me the link that starts the free listing check at diagnostic.booster.delivery (format: https://diagnostic.booster.delivery/?url=MY_LINK&utm_source=YOUR_NAME) and tell me what the report will show.

What happens next

The page opens with your link already filled in and the check starts by itself. About a minute later the report is ready: rating and how many ratings back it up, photos and descriptions, items switched off right now, what customers complain about in the last 50 reviews, and an estimate of orders lost. You can send the report to yourself in Telegram, WhatsApp or email from the report page. A restaurant checked within the last 7 days returns the same report instead of a new run. A few checks per hour from one network.
