meraGEO

meraGEO measures how a company appears in the answers of major AI assistants, a practice it calls generative engine optimisation. Its maker introduced it on Hacker News on 1 October 2026. A user enters a domain, and the tool crawls the site, runs user-intent queries across three assistants and returns a visibility score.

Features

• Visibility scan: a check of how ChatGPT, Claude and Gemini mention the brand, with a score and a breakdown of where it is missing. The scan needs no sign-up and takes about 30 seconds.
• Weekly rescans: paid monitoring that reruns the scan each week, emails when the answers change and keeps a history of every scan.
• Fix report: a list of what to change, with a brief that a coding agent can work from.
• Rival view: a weekly digest of the competitors the assistants name in place of the brand.

Key facts

• Scan time: about 30 seconds, with no sign-up
• Assistants covered: ChatGPT, Claude and Gemini
• Reading scores: answers vary between runs, so the scores are better read as a trend than as a fixed ranking
