Updated · Based on published facts
OpenSEO is an open-source alternative to Semrush and Ahrefs, MIT licensed, with keyword research, rank tracking, backlinks and site audits. You can self-host it and pay providers directly, or use its hosted plan at US$10 a month with US$10 of usage included.
It also tracks AI answers. You can save questions and run checks manually or daily, weekly or monthly across ChatGPT, Gemini, Google AI Overviews, Claude and Perplexity. It keeps answers, citations and competitor appearances over time. ChatGPT and Gemini use consumer-site collection; Claude and Perplexity use model APIs. Those answer surfaces can differ.
The pricing calculator estimates about US$0.002 per prompt per platform. Immediate checks cost more than scheduled checks; Claude and Perplexity use live API pricing. Preview the cost before starting. Its MCP connection can research prompts, configure tracking and read or export saved answers and trends without another collection charge. These are published capabilities; we have not independently tested their accuracy.
What we measure
We ask all seven AI engines, ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek and Google AI Overviews, the questions your buyers type, and we show you exactly what each one said. A full measure runs up to twelve buyer questions with nineteen answers each, six engines asked three times and majority-voted plus one read of Google AI Overviews, which is up to 228 answers, so one lucky answer proves nothing.
We record which competitors each engine named instead of you, on which question, and how often. That is the moment a buyer chooses, and it is the number an owner asks for first.
Where an engine exposes the web searches it ran before answering, we capture them and keep them with the answer. Read those searches alongside the saved answer to see what the engine searched for.
We check your identity against the government business registry, ABN-verified, and map visibility suburb by suburb, because a plumber in Buderim does not care about national sentiment.
We write the fix rather than recommend one: the schema, the llms.txt and the readiness changes for your entity, ready to publish. With Pro, you choose when to re-measure and see the token cost before confirming. Your own AI can read saved measurements over MCP.
Where OpenSEO is the right tool
Keyword volumes, backlink profiles, rank tracking in classic search results, crawl-scale audits, and a stack you host yourself and pay for by use. We do not do any of that and do not pretend to.
What is open on our side
Our readiness scoring and the audit suite are public at github.com/techhorizonlabs/thl-open, so a developer who likes OpenSEO for being open can check that part of our method the same way. The hosted measurement across the seven engines is a service we run, and we say so. OpenSEO publishes its whole platform; our open source covers the readiness method and audit suite.
Run both
Both tools can track what AI says about a business. OpenSEO combines that with classic SEO research and a platform you can host yourself. Our service focuses on buyer questions, saved answers, competitors and a fix plan. Try the questions that matter to your business and compare the evidence. Our free scan asks two questions on two engines, with no signup: areyoufoundbyai.com
