Reglynn turns the EU AI Act into a decision you can act on. Most founders don't ignore the AI Act — they can't tell whether it applies to them. Finding out costs €300/hour, and free tools hand you a risk tier with no reasoning behind it. Reglynn asks 32 questions about what your AI system does,...

As answered by people managing Codewars and Reglynn.eu.
Reglynn.eu's answer:
Three things. It uses the correct post-Omnibus deadlines — most published guidance still carries the pre-June-2026 dates, which tells high-risk providers they're late when they aren't, and tells chatbot builders they have time when they don't. It runs the Article 6(3) exemption check, which almost no free tool does, so it won't tell you you're high-risk when the regulation says otherwise. And it publishes its own AI Act self-assessment, because Reglynn is an AI system under the regulation it assesses.
Reglynn.eu's answer:
Free checkers give you a risk tier with no reasoning. Enterprise GRC platforms give you a subscription starting in the tens of thousands. A lawyer gives you an answer at €300/hour. Reglynn gives you a dated, structured document you can put in front of an enterprise procurement team — once, for €59.
It also works hard not to over-classify you. The report runs role, then GPAI, then the Article 6(3) exemption, then establishment, in that order, because assigning someone else's obligations to a deployer is what makes these tools useless.
Reglynn.eu's answer:
Founders, product managers and operations leads at EU or EU-serving companies with 5–50 people who ship an AI feature — chatbots, generative products, scoring or ranking models, AI-assisted screening. Typically the trigger is an enterprise prospect's legal team asking for their AI Act position in writing, with a deadline attached. Not lawyers, and not enterprises with a compliance department.
Reglynn.eu's answer:
After the June 2026 Omnibus, the coverage said "the EU delayed the AI Act." That's half true, and it's the reassuring half. High-risk obligations moved to December 2027 — but Article 50 transparency duties were never deferred, and regulators gained fining powers on 2 August 2026.
So the group with live obligations right now is precisely the group that read "delayed" and stopped paying attention. Reglynn was built to close that gap for companies that can't put €300/hour behind finding out.
Reglynn.eu's answer:
A static site on Netlify. Assessment through structured forms, with report generation via Anthropic's Claude API against Reglynn's own question set and classification logic. Delivery logging in Airtable. Analytics via GA4 with Consent Mode v2, denied by default.
Reglynn.eu's answer:
Reglynn launched in August 2026 and doesn't publish customer names. Buyers are typically 10–50 person AI companies responding to an enterprise procurement or due-diligence request.
