The AI 500
Hey HN, I've been trying to correct for one of the biggest difficulties with moving from SEO -> GEO, which is the lack of public data (in the same way that for SEO we had ahrefs/semrush/etc). To try and start fixing this, I've built a searchable database of 15k brands, across 500 different industries, with daily updates. Each morning, the tool goes out and queries 10k different prompts, and normalises the results to all the relevant brands.

What it does
The first public benchmark of AI brand visibility. We query ChatGPT, Claude, Gemini & Perplexity across 500 industries with 5,000+ real prompts to track which brands get recommended. Like the S&P 500, but for AI. • 15,000+ brands ranked • 500 industries covered • Updated daily • Model disagreement analysis • Compare any two brands head-to-head See where you rank before your competitors do.
A selective, daily view of the brands AI assistants mention most, with real sample sizes, movement, methods and strict checks for search quality.
A smaller, checked rankings publication built from observed AI answers. Every current page shows its date, sample, method and limits. Movement is supplied by the public feed. Category pages do not infer movement when it is unavailable. Showing 100 of 500 brands. Visibility is a 0-100 source score, not a market-share percentage. 26 categories are in the publication set. Each page must pass the live gate before it can be indexed. Career-change questions comparing structured routes into software development. Fit, support and use-case questions across everyday and specialist bras. Card recommendations for rewards, cash flow and business spending. Replacement and upgrade questions across common…from trakkr.ai

MentionedBy AI2025 · mentionedby.ai · ▲39A few weeks ago I shared an early version of MentionedBy.ai — a tool we built to monitor how your brand is mentioned inside AI-generated answers from ChatGPT, Claude, Gemini, Perplexity, and other LLMs. We’re now officially live This started from our own frustration. Our startup wasn’t being mentioned in ChatGPT responses, even for queries where we were clearly relevant. Meanwhile, legacy or SEO-heavy brands kept showing up. We realized: AI is becoming the new search engine — and no one knows how they rank in it. So we built MentionedBy to answer questions like: How often does your brand…

AI search results are quickly becoming more important than SEO, but as businesses, we have no visibility over it! That's why I'm building "Ahrefs for AI search results". Track keyword performance on AI tools like ChatGPT, Claude, Perplexity & more

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
