Vanh Tran

The public experiment

Build Log

ChatGPT doesn't know I exist, and I have 180 days to change that. This is where the experiment is written down as it happens: Geovily experiments, AI-search tests, launches, failures and Sunday recaps. Start with the first entry.

One run per prompt on ChatGPT, Perplexity, Claude and Gemini. Recognition means the answer identifies Vanh as the Hanoi-based builder or names him as Geovily's founder. Prompt echoes and Geovily-only mentions do not count; Google AI Overviews was not part of this check.

Income and weight are Sep 27 figures. Client and conversation counts remain at the Sep 24 baseline.

  1. Building vanhtran.dev: static, MDX, nothing to log in to

    Why the home for this experiment is plain files in a repo, and what that makes easy for crawlers and AI engines.

  2. Day 1: ChatGPT doesn't know I exist

    The Geovily baseline: 7 questions on ChatGPT, Perplexity, Gemini and Claude, what came back, what I changed that day, and how I'll track 5 engines.
