Kimi Review UK: Is a £19 Membership Worth It, and What Does Code KN9KB5 Add?

Kimi is the AI assistant and agent made by Moonshot AI; the app is published by Beijing Moonshot Technology Co., Ltd. It runs on Moonshot's own models, currently Kimi K3.1 Pro, and goes well beyond chat: it builds slides, documents and spreadsheets, runs deep research, generates and deploys websites, writes code through Kimi Code and can coordinate up to 300 sub-agents across 4,000 steps in Agent Swarm.

It works on the web, on Windows and Mac through the Kimi Work desktop app, and on iPhone and Android, in English and 15 other languages. It is a consumer software subscription, not a financial product, so no UK regulator stands behind it: what protects you is Kimi's own terms, the app store you pay through and UK consumer law.

Chatting with Kimi is free. A membership adds a monthly pool of credits for agent work and unlocks more features. On the UK App Store on 24 October 2026, Plus cost £19.00 a month or £179.99 for an annual pass, Pro £39.00 a month and Max £99.00 a month. The store still lists the older plan names, Moderato, Allegretto, Allegro and Vivace, at the same prices: Kimi renamed its plans without changing what they cost, and existing subscribers keep their old plan.

Kimi's help centre publishes its full plan table only for China, priced in yuan: Go ¥49, Plus ¥99, Pro ¥199, Max ¥699 and Ultra ¥1,399 a month. That table shows how the tiers step up. Go has no Kimi Code; Plus adds Kimi Code and Agent Swarm with twice Go's agent credits; Pro adds Goal Mode, a dedicated Kimi Claw and K3.1 Pro's 1 million-token context; Max and Ultra add more credits and parallel tasks. If you pay on the web rather than through Apple, checkout shows the price for your region before you confirm.

Every membership feature, from Agent and Deep Research to slides, Kimi Code, Kimi Work and Kimi Claw, draws on one monthly credit pool, charged by the tokens a task consumes. A long research job can use a large share, and when the pool runs out every feature stops until it refreshes. Credits refresh monthly on your subscription date, even on an annual plan, and unused credits don't roll over.

Two background charges catch people out. A deployed Kimi Claw cloud host takes about 0.6% of your membership credits every day at 4pm, whether or not you use it, and a website you have published with Agent takes about 0.08%. Delete the host or unpublish the site to stop them. Kimi Code also has a rolling five-hour limit, and paying members can switch on Extra Usage, a pay-as-you-go balance shown in yuan with a minimum ¥25 top-up.

Kimi's Moon Companion Plan is a standing campaign, run under rules in force since 20 September 2026. Open our link, confirm the invitation so your account is bound to code KN9KB5, then subscribe to any Kimi membership and complete payment within 24 hours. Miss the 24 hours and the invitation lapses. You then get one draw on the campaign page, reached from Invite & Earn Rewards in the sidebar. Kimi's invite page says every draw wins a prize.

The prizes are Kimi Go membership-equivalent credits in five tiers: 3 days, 7 days, 15 days, 1 month and 1 year. They measure an amount of usage, not time, so the 1-year tier doesn't give a year of service, and all of them expire on 31 December 2026. Prizes are tied to your account: you can't transfer, sell or cash them out. Disclosure: KN9KB5 is BonusRoam's own code, so when you complete the task Kimi gives us one draw too.

Say you take Plus through the UK App Store for £19.00 a month. That payment is the cost of the draw, and the draw returns one prize tier. Kimi doesn't put a price on the prizes, but its China price list gives a yardstick: Go costs ¥49 a month, about £5.50 at the European Central Bank's 23 October 2026 rates (£1 = ¥8.917). On that basis a 3-day prize is worth about 55p, 7 days about £1.28, 15 days about £2.75, a month about £5.50, and a year about £52.48 at Go's ¥468 annual price.

Two things cut that further. Kimi publishes no odds, so you can't count on the bigger tiers, and every prize expires on 31 December 2026: from 24 October that leaves 68 days to use even a year's worth of credits. Go also carries half the agent credits of Plus in Kimi's table. The draw is a pleasant extra if you wanted Plus anyway, and poor value as a reason to subscribe.

Only the first successful subscription by the same person counts, and only the first inviter is credited. Renewals, upgrades, repeat subscriptions and price-difference refunds don't add another draw. The campaign is for personal accounts; Kimi Business users can't take part. Once you use a draw it can't be cancelled or given back.

If the subscription is fully refunded, cancelled or found invalid, Kimi treats the task as incomplete and withdraws any unused draws on both sides, while draws already used and prizes already won stay with you. So draw soon after paying. Your prizes appear under My Prizes on the campaign page and the credit bar under My Subscription, sometimes after a short delay. If a draw never appears, contact Kimi support with both accounts, a screenshot of the campaign page and the rough times of binding and payment.

Kimi's privacy policy, effective 31 August 2026 and linked from the UK App Store listing, names Beijing Moonshot Technology Co., Ltd. as the company handling your data and says it stores personal information within mainland China. It collects your phone number, your conversations and uploads, device details and payment records for memberships.

The policy says Moonshot uses de-identified inputs and outputs to improve its models; you can ask customer service to stop using your content for training, and switch off the memory feature in settings. Treat Kimi as you would any overseas service: keep client files, medical details and anything covered by an employer's data rules out of it.

Through the App Store you pay Apple in pounds at the prices above; on the web, checkout shows the price and currency before you pay. Under-18s may only buy with a guardian's consent. Upgrading takes effect at once, with the unused days of your current plan credited against the new one.

To cancel, go to Settings, then Subscription Management, and choose Cancel Auto-Renewal on the web or app, or cancel under your Apple ID's Subscriptions if you paid through Apple. Your benefits last until the end of the period you have paid for. Kimi treats paid services as used once activated and doesn't refund them unless the law requires it, so pick monthly billing first if you aren't sure the credit pool is enough.

On 24 October 2026 Kimi was rated 4.7 from 471 ratings on the UK App Store and 4.5 from 48,200 reviews on Google Play. Happy users praise its writing, its research and how much the K3 models improved its coding and agent work.

The complaints repeat. Free users are told Kimi is too busy and pushed to upgrade; sign-in leans on a phone number, and some SMS codes never arrive; heavy users on annual plans hit the monthly credit limit within days of a big project; and voice input lags behind rival apps. None of these affects the draw, but they matter more than the draw when you decide whether to pay.

Use our link if you already plan to pay for Kimi for agent tasks, slides, research or Kimi Code, you are comfortable with data stored in mainland China, and you'll get through any prize credits before 31 December 2026. Bind the code first, pay within 24 hours, then draw straight away.

Skip it if you want a reward without paying, if you would subscribe only for the draw, if your work involves confidential or regulated data, or if you need usage you can predict month to month, since a heavy project can drain the shared pool early.
