Plans and credits
Start with a 7-day free trial, then subscribe to Starter, Pro or Business. Credits pay for AI features and belong to the person who runs them.
Credits are the usage currency for every AI feature in Ngenaire — the co-engineer, critiques, quality analysis, document drafting and report generation all spend them. Credits belong to the acting user, not the organization: whoever runs an AI action pays from their own balance, even in someone else's project.

Free trial
Every new account starts with a 7-day free trial: full access to the platform plus welcome credits to try every AI feature. No card required.
When the trial ends without a plan, only your account and billing pages stay reachable until you subscribe. Your projects and data are kept, and subscribing restores full access immediately. Subscribe during the trial and access continues without a break.
Plans
Three plans — Starter, Pro and Business — each grant a set amount of subscription credits per billing period. Pay monthly or annually; annual billing works out at roughly two months free. Current prices and allowances are on Plan & credits and on the public pricing page; use the Monthly / Annual toggle to compare.
The two credit buckets
| Bucket | Source | Carryover | Spent |
|---|---|---|---|
| Subscription credits | Granted by your plan each billing period | Reset at the period rollover | First |
| Top-up credits | One-time purchases, plus the welcome grant | Carry forward while you are subscribed | After subscription credits |
Subscription credits always drain first, so you never lose credits that were about to reset anyway.
Top-ups are a subscriber perk. Buying and spending top-up credits requires an active subscription. If you cancel, you can keep spending until the end of the period you paid for; after that, remaining top-up credits are locked — kept on your account, but unusable until you subscribe again. Welcome credits stay usable during the trial, before your first subscription.
Subscribe
- Open Plan & credits and choose Monthly or Annual.
- Click Subscribe on the plan you want.
- The first time you buy, the payment dialog asks for your billing address. It is used to calculate tax and remembered for later purchases; Change updates it.
- Review the Subtotal, Tax and Total, then enter your card. Payment is handled by Stripe in a dialog on the page, including any 3-D Secure challenge.
- Subscription credits land within seconds and the balance refreshes.
Listed prices exclude tax; the exact tax for your address appears before you pay.
Change plans
- Upgrades (a higher plan, or monthly to annual) take effect immediately, prorated: your saved card is charged the difference for the rest of the period and the new plan's credits are added right away.
- Downgrades (a lower plan, or annual to monthly) are scheduled for the start of your next period. Nothing is charged today.
- Changed your mind about a scheduled downgrade? Click Cancel switch on the banner above the plans.
Buy top-up credits
- In the top-ups section, pick a pack. The middle pack is marked Best value.
- Click Buy and confirm payment in the Stripe dialog, which shows the tax for your billing address first.
- Credits land in your top-up bucket within seconds.
Manage your subscription
Open billing portal opens the Stripe customer portal, where you update your payment method, download invoices and cancel your subscription.
Balance and history
Plan & credits shows your current balance, subscription status and a transaction history — every grant and every charge, with the project each charge came from. Before an AI action starts, Ngenaire checks your balance covers a small reserve for that feature; when it finishes, you are charged the actual usage. Quick /fast answers cost a fraction of /heavy analysis or AI report generation.
Running out of credits
When your balance cannot cover an AI action, the action is declined and an out of credits prompt links here. Top up or change plan to continue. Non-AI work — editing, tracing, verification, schedules — is unaffected, and a few AI features fall back to rule-based results.
Running out of credits only stops AI actions. An expired trial without a subscription is different: it limits the whole app to your account and billing pages until you subscribe.
Tips
- Watch the low-balance warning and top up before you hit zero mid-task.
- Spend subscription credits first. They reset at the rollover; top-ups do not.
- Check the transaction history to see exactly which project and feature spent your credits.
