An operator-led indirect-tax change-control workspace for the digital economy, turning monitored VAT/GST developments into human-reviewed, business-specific decisions, owned actions, deadlines and audit evidence.
Kehai doesn't replace tax judgement. It gives that judgement an operating system.
Kehai (気配) is the Japanese word for a sensed sign that something is about to happen - the shift in the air before it rains. It's almost a literal description of regulatory horizon-scanning.
Human-reviewedPrimary-source prioritisedSource-citedBuilt for triage and change control
Sourced from official sources
For each jurisdiction you configure, Kehai watches the official primary sources first (tax authorities, official gazettes, the courts and official e-invoicing platforms) and prioritises them over newsletters and commentary. Every item is labelled ◆ primary or ◇ secondary, and secondary items carry a verification warning wherever they appear.
Matched to your business
Each change is assessed for relevance to your specific business and marked affects, maybe or no, with a plain-English reason, a suggested owner and deadline, and a forward time-to-act. It is presented as an AI suggestion until a specialist reviews it, never as settled fact, so the same development can legitimately matter to one business and not another.
Cited and human-reviewed
Every item carries its source, and material items are reviewed by a person before they are relied on. The distinct trust signals (official source, claim support, reachability, human review) are shown separately and never collapsed into a single tick, and an unverified link is never treated as proof. Where an official register is available, items are cross-checked against it.
Monitored with measured coverage
Monitoring runs continuously on a schedule, without manual intervention. Coverage is measured against the official sources you have configured, and any gap (a source not seen recently, or never reached) is surfaced rather than hidden, so you can see what is and is not being watched.
Audit-ready
Reviews, assessments and sign-offs are kept in an append-only audit trail, and any item can be exported as a self-contained evidence pack (the claim, its source and its review history) to hand to an auditor.
Local-language sources, handled honestly
Sources are monitored in their original language - French, German, Dutch and beyond - and Kehai does not require an English-language source to exist. The summary and business impact you read are AI-generated in English from that original: a working summary, not a certified or word-for-word translation, and labelled AI-generated until a reviewer signs it off. When a source is checked, its original-language text is captured point-in-time, so a reviewer (and an auditor, via the evidence pack) can compare the English claim against the source's own words.
Known limitations
Coverage depends on what web search surfaces at run time: items can occasionally be missed, mis-dated or mis-classified, and the freshest developments may take a refresh cycle to appear. Coverage is measured against the configured scope, not the whole world. Relevance assessments are AI-generated and labelled as such until a reviewer signs them off. Kehai is a triage aid, not legal or tax advice: always confirm any item against the cited authority, and verify material conclusions with a qualified adviser, before acting on it.
What Kehai does not claim
Complete or guaranteed global coverage of every relevant development.
Legally verified conclusions or autonomous tax advice.
That a reachable source URL proves a particular claim.
That AI-labelled “primary” content is independently official until the domain is matched.
That an AI relevance assessment is correct until a reviewer has checked it.
That the English summary of a local-language source is a certified or word-for-word translation of it.
Enterprise-grade security or availability before those controls exist and are evidenced.
