The compliance passport
Verify a person once, reuse it everywhere
One identity verification clears director identity checks, right-to-work, the identity portion of a DBS check and AML customer due diligence. Dulycore holds the verified record and applies it wherever a regime asks — so people stop repeating the same check for every process.
How the passport worksFilings
Prepared by Dulycore. Confirmed by you.
Dulycore prepares filings and holds them at a review gate. Nothing is submitted to Companies House, HMRC or any regulator without a named person's sign-off, and every confirmation is logged with a reversal recipe. That is a design decision, not a limitation.
See the review gateReview before anything is sent
Logged with a reversal recipe. Nothing is submitted without this step.
Agent-ready
Built for the agentic era
Dulycore is readable by the AI tools your company already uses. The site ships llms.txt and AGENTS.md from day one, and a read-only connector for AI assistants is in development — so your tools can answer "what's due this month?" from the same record you see. Inside the product, the work is visible: every card shows when its source was last checked and how confident the extraction is.

Security
Built like the systems it watches
A compliance product holds sensitive records, so the standards it tracks are the standards it keeps.
Your data is stored and processed in the United Kingdom, encrypted in transit and at rest.
Each company's records are walled off from every other company's at the database layer.
Every action is recorded with a reversal recipe — nothing happens silently.
No filing reaches a regulator without a named person's sign-off.
Your documents are never sold, never shared for advertising, and never used to train public AI models.
What the calendar catches
The full calendar covers every regime that applies to your company — these are ten of the common ones.
