Perplexity
From Perplexity
A research box that shows sources beside the answer. Use it to see how an answer engine cites the web. It will not rank your site by itself.
- Best for
- Checking what an answer engine cites, and doing sourced research without a blank chat.
- Pricing hint
- Free tier and a paid Pro plan.
Perplexity is the editorial pick for GEO because you can watch the citations. It is a reading tool, not an SEO suite. Pair it with your own pages and, if you pay for one, a research suite.
Where it fits
- Sources are visible, which is the whole point for GEO.
- Fast when the question is factual.
Where it does not
- Citations can be thin or off-target; open them.
- It is not a content optimizer.

Others in GEO
- Ahrefs — The research suite for links, keywords, and competitive pages. Expensive. Some plans add reports about AI answers; treat those as a supplement to looking yourself.
- ChatGPT — The default general assistant. Broad enough for everyday writing and light tool use, and less predictable than Claude when a long edit has to stay careful.
- Claude — The best default for long documents and careful agent-style work. Easier to steer than most chats, and less of a do-everything platform than ChatGPT.
- Gemini — Worth opening when the work already lives in Google, or when you want image generation in the same chat. Not the first pick for code or a long edit.
