Six endpoints an assistant can read

We run these on our own domain. Open any of them — this is the same output your site gets.

Being cited is not the same as ranking

Assistants do not wait to be retrained on your website. When someone asks a question, the assistant retrieves sources at that moment — from live search, indexes, connectors and directories — and writes an answer from what it can read and corroborate. If your business is hard to parse, absent from the places it checks, or contradicted elsewhere, you are left out of the answer. That is the gap Tunnel works on.

Retrieved

A crawler has to reach your pages and read them without running JavaScript.

Parsed

Your facts — hours, services, location, pricing — have to be machine-readable, not baked into images and layout.

Corroborated

The same facts have to agree across your site, your listings and third-party sources.

Frequently asked questions

How quickly will I see results?

Honestly: nobody can promise you a date, and anyone who does is guessing. Assistants do not wait to be retrained on your site — they retrieve sources at the moment someone asks, from live search, indexes and directories. So what matters is whether your pages are reachable and readable, whether your facts agree across the web, and whether the assistant’s retrieval layer picks you up. Our side is quick: endpoints are live within a day of your first crawl. After that we measure what the assistants actually say, on a schedule, and show you the answers.

Which AI platforms do you monitor?

We query ChatGPT, Google Gemini, Microsoft Copilot, Claude, Perplexity and Grok. To be precise about what that means: we publish your business data in the formats assistants and agents read, and we measure how you appear in their answers. We do not optimise inside their systems — no vendor can.

Can I try it before paying?

Yes — the free tier IS the trial. One website runs the full pipeline: crawl, GEO endpoints, keywords, daily visibility checks. No credit card, no expiry. Upgrade when the numbers convince you.

Can I cancel anytime?

Absolutely. No long-term contracts — cancel anytime and your plan stays active until the end of the paid period. Your free-tier website keeps running after that.

How is this different from traditional SEO?

Traditional SEO competes for a position in a list of links. We work on whether an assistant can retrieve, parse and corroborate your business well enough to name it inside an answer — structured data, machine-readable endpoints, pre-rendering for crawlers that do not run JavaScript, and consistency across your listings. Note that this is about retrieval at answer time, not about getting into anyone’s training data.

Do you work with local businesses?

Yes, and it is the case we are built for — including businesses with no website at all, which we can list from your Instagram, TikTok or Facebook presence. That covers Google Business Profile, local directories, and location-style questions such as “best bakery in Chișinău”.

The free tier is the trial

No card, no countdown — one website runs the full pipeline for free, forever. Upgrade when your own visibility numbers make the case.
