GPTGO
A thin front-end that calls Google and a chat model on your behalf, useful only if you want both on one page without logging in anywhere. Perplexity does the same job with real citations and free ChatGPT already browses the web, so the case for this has largely evaporated since 2023.
Pros
- Zero friction: no login, no key, no quota prompt
- Keeps conventional search results next to the generated answer rather than replacing them
- Mobile apps exist for both iOS and Android
Cons
- No company, jurisdiction or contact is published anywhere on the site
- The underlying model and its version are never named, so answer quality cannot be audited
- Generated answers are not source-attributed the way Perplexity's are
- Ownership of the mobile apps sits under a different name (UniChat / UniAPI) than the website brand
