- Unlimited decision runs — no allowance, no counter, no card
- Three released, test-gated decision models — business runway, career change, major purchase. Test-gated means 711 automated checks pass on every release; it does not mean the forecasts have been proven accurate: no accuracy is claimed until ten outcomes have resolved
- Seeded, reproducible simulations with honest probability bands, receipts and the challenge case
- Three saved decisions with outcome reporting and calendar reminder files
- Three Copilot messages a day — describe a decision in your own words and it fills the form from what you wrote; ask it to explain or challenge a result. Every figure in its replies comes from the engine, or is removed
- Local-first privacy — simulation inputs stay on this device; the optional Copilot sends only what you deliberately type or ask it to summarise
Checkout is not switched on for this site yet — everything below is built and waiting behind it.
No card for the trial. If you add one, Pro continues at the price above; if you do not, it ends and nothing is charged.
- Everything in Free, plus:
- Every decision kept — an unlimited ledger of frozen forecasts, resolutions and scores
- Exports and PDF reports — the portable decision package and the printed record
- The calibration view — your own accuracy record, scored over time (needs resolved outcomes to show anything — it is honest, not decorative)
- Resolution reminders — the day reality answers, in your calendar today; by email when the sending domain is connected · email is planned
- The AI Copilot, sixty messages a day — plain-English intake, the explanation of a result and the assumption challenger; AI text is labelled and no number in it comes from the model
Founding-member pricing: the price you join at is the price you keep. Anything marked planned is not yet sold as if it existed.
- Everything in Pro, for every seat
- Board-ready report generator — the Decision Record as a paper a board can read (the sample · PDF, 9 pages)
- Audit-trail export — the hash-chained record of who did what, when
- Board summary from the Copilot — an AI-written executive summary of a frozen result for the Decision Record, every figure from the engine; two hundred Copilot messages a day per seat
- Shared client workspaces, roles and approvals, SSO and API keys · planned — the hosted service, Release 2
- Enterprise £25,000–£100,000 a year — agreed after a pilot, never sold from a page
- Founding pilot £1,500: one consequential decision through the complete Decision Loop in 30 days; what it includes. Decision Audit £2,500–£15,000 per engagement; the three packages
Seats are bought here when checkout is switched on; Enterprise, pilots and audits are invoiced. Nothing marked planned is sold as if it existed. The full entitlement table is on packages.
Pricing & consumer rights: payment is handled by Stripe — LEXUN never sees or stores your card details, and Apple Pay, Google Pay and cards all work at checkout. Prices are in pounds sterling. LEXUN is not currently VAT-registered, so no VAT is added at checkout and no invoice shows any; if that changes, Stripe Tax will add it and the prices above stay the net figure. You have 14 days to cancel a new subscription for a full refund under the Consumer Contracts Regulations 2013; after that, cancelling stops the next payment and you keep what you paid for to the end of the period. The decision engine is free to use. There is no card and no charge — checkout is not switched on for this site yet, and until it is nothing is limited.
Cancel anytime. Local-first by default — your saved decisions stay on your device (encrypted sync across devices is on the waitlist, not live). LEXUN is decision intelligence, not financial, legal or medical advice.
Which door is yours?
For individuals
Free covers the whole decision loop with unlimited runs; Pro keeps every decision, adds exports, reports, the calibration view and the Copilot. The maths is identical on every tier — a paid plan never buys a better probability, only a kept record.
For organisations
Organisation seats, an Enterprise agreement after a pilot, the founding pilot and the Decision Audit. Start from the organisations page; every capability is labelled live or planned, and nothing planned is sold as live.
For education
Classrooms use the browser engine free — no accounts, no student data collected. Pilots and course support are arranged through the contact page, not a checkout.
Questions
Is the free plan really free?
Yes. Unlimited decision runs, no card at any point unless you choose to upgrade, and no account: saving a decision needs a LEXUN Key, a passcode that encrypts the record on your own device. The 14-day Pro trial also needs no card — it simply ends if you do not add one.
What does Pro add?
The record. Free keeps three decisions once checkout opens (nothing is limited until then); Pro keeps every one, with exports, PDF reports and the calibration view, and lifts the Copilot's daily allowance. The engine is the same on both: a paid plan never buys a different answer. Anything not yet built is labelled planned on this page and is not charged for.
How is my data handled?
LEXUN is local-first: your data lives in your browser, not our servers. No advertising or tracking cookies, nothing sold. See our Privacy and Cookies policies.
Can I cancel?
Any time, in one step: Settings → Manage plan in the workspace opens the Stripe billing portal, where you can change plan, change card, download invoices or cancel. Cancelling stops the next payment; you keep what you paid for until the end of the period, and every decision you saved stays readable on the free plan. If anything goes wrong, hello@lexun.co.uk is read.
Is there a run limit?
No. Free runs are unlimited and always will be; the paid plans sell the record, not the run. A plan is confirmed with Stripe each time you visit rather than trusted from a marker in your browser, and if that check cannot be made your last confirmed plan stands for seven days. A plan that ends loses nothing you saved.
