​
What do I use credits for?

You use credits when AI creates or edits text and images, based on the work it processes. Light, Pro, and Max also include a daily allowance for lightweight models that don’t spend credits. See “Can I use Inki without limits?” on this page for the models and limits.

​
How many credits will I use?

Actual credit usage varies based on the selected model, content length, and conversation. Credit use for image generation and image editing varies based on your instructions, the image used for editing, and the generated result. With Astra 6, Sol 6, Sol 6.1, Sol 5.6, and Terra 5.6, long-input pricing applies when the input for a single processing request exceeds 272,000 tokens. This includes conversation history, reference text, and reused input. The rate applies to the whole request, rather than just the portion above the threshold. Input rates are twice the usual rates, and output rates are 1.5 times the usual rates, so the increase in credit usage depends on the amount of input and output. Past usage won’t be charged retroactively.

​
Plans

Inki offers Free, Light, Pro, and Max. Higher plans come with more monthly credits. Pro and Max plan members can also purchase additional credits. Check inki.so for the latest pricing and plan details.

​
Billing Cycles

  • Light and Pro are available with monthly or annual billing
  • Max is available with monthly billing only
  • Annual plans still add and reset credits every month instead of granting a full year of credits at once

​
How Credits Work

  • Each plan gives you monthly credits that reset every month and do not carry over
  • Bonus credits, purchased credits, and plan carryover credits can carry over
  • Plan carryover credits have an expiration date
  • Check expiration dates in Settings. Credits that expire on or before your next monthly reset are used first
  • Pro and Max plan members can purchase additional credits
  • Check your balance in Settings > Usage in a desktop browser or the Mac app, or Settings > Plan in the iOS app or a mobile browser. During a trial, Settings > Usage also shows when your trial credits expire
  • If AI Editing, Inline Generation, or Review ends with an error before producing a usable result, it normally doesn’t use credits. The exception is a review that reaches a usage limit after generation has started: it uses credits for generation already completed, even if no result is saved. A review blocked by a limit before generation starts doesn’t use credits
  • If AI Assistant ends with an error, only the work it actually processed uses credits. If it processed nothing, it doesn’t use credits
  • Retrying after an error is a new request and uses credits for what it actually processes
  • Image generation and image editing use credits once a result image is created. Discarding the result without adding it to your note or replacing the original image does not refund those credits. Generations recorded as failed by the server don’t use credits. If the app stops waiting before processing finishes, a generation that later completes can still use credits

​
Automatic Credit Top-ups

Pro and Max subscribers billed through the web can buy credits automatically when their balance falls below a chosen threshold. In a desktop browser or the Mac app, open Settings > Usage and turn on Auto top-up to show its settings. Set the threshold and purchase limit for the period, then review the price, credits, and saved payment method before confirming. If your balance is already below the threshold, a purchase may happen immediately after confirmation. Choosing “No limit” allows another charge each time your balance falls below the threshold. Turning auto top-up off prevents further automatic purchases. If payment fails or a scheduled plan change or cancellation turns auto top-up off, follow the on-screen guidance and turn it on again once the issue is resolved. App Store subscriptions aren’t eligible for auto top-up.

​
Plan Changes

For a paid subscription purchased on the web, open the “Plan” tab in Settings to change your plan.
  1. In a desktop browser or the Mac app, open “Manage billing” and choose a plan and billing cycle
  2. Review the charge and effective date on the confirmation screen. If credits carry over, you can also check their balance and expiration date
  3. Click “Confirm change”. If your card issuer requires verification, follow the on-screen instructions to complete it
If you close verification before finishing, select “Continue verification” to resume. If you miss the displayed deadline, the change is canceled and your current plan continues. In a mobile browser, choose a plan and billing cycle in Settings to open the confirmation screen within Inki. Check the charge and effective date before confirming. You can return to Settings after completing or canceling the change.

​
Upgrade

  • Switching to a higher plan, or from monthly to annual billing on the same plan, takes effect immediately
  • A new billing period starts, and new plan credits apply right away
  • Unused credits for the current month become plan carryover credits whether your paid plan is billed monthly or annually. Check the confirmation screen for their expiration date
  • When upgrading from annual billing, prepaid fees for months that haven’t started are applied to the charge. Any amount left over stays on your account and is applied to future invoices

​
Downgrade or Switch the Same Plan from Annual to Monthly Billing

  • Switching to a lower plan, or from annual to monthly billing on the same plan, takes effect at the end of your current billing period
  • Keep your current plan until then
  • No plan carryover credits are granted
  • To cancel a scheduled change, find the upcoming switch under “Current Plan” in Settings

​
Undo a Scheduled Cancellation

For a web subscription, a scheduled cancellation shows an end date in a desktop browser or the Mac app under your current plan in Settings > Plan. To undo it, open “Manage billing” on the same screen.

​
Discount Notice after a Trial

If a discount notice appears after you use up your trial credits, choose “Choose a plan” to open plan selection. The discount applies automatically when you sign up for an eligible plan before the deadline. You don’t need to enter a coupon. Check the eligible plans and charges on the plan selection and checkout screens. After closing the notice, you can still open plan selection from the discount ticket before it expires. Find it at the bottom of the sidebar in a desktop browser or the Mac app, or at the bottom of the menu in a mobile browser. The ticket shows the remaining time. This discount notice doesn’t appear in the iOS app.

​
Which AI models can I use?

You can choose many models on Free too. Opus 5, Opus 5.5, Fable 5.1, Astra 6, and Sol 5.6 require Pro or Max. Check the model menu in each feature for the models you can currently use. Models that require a plan upgrade appear locked. See Models and Reasoning for help choosing a model and setting reasoning.

​
Can I use Inki without limits?

On Light, Pro, and Max, you can use lightweight models without spending credits up to 300 times per person per day. The number of uses isn’t unlimited. This includes Luna 6 and Haiku 5.5 where it’s available in your model menu. Both models and all three features, AI Assistant, AI Editing, and Inline Generation, share this allowance. It resets at midnight Japan time (JST). This limit helps keep access fair for everyone. Other models and features, and Free and trial plans, use credits as usual.

​
Can I keep using AI after my credits run out?

Yes. On Light, Pro, and Max, you can continue with Luna 6 or Haiku 5.5 where it’s available in your model menu, until you reach the daily limit. AI Assistant’s Auto continues with Luna 6. To use Haiku 5.5, select it in the model menu. In a desktop browser, the Mac app, a mobile browser, or the iOS app (version 1.0.18 or later), your first request after running out of credits asks whether to continue with a lightweight model, including when you use Auto. In AI Assistant on desktop browsers and the Mac app, choose “Continue with the lightweight model” on the card above the message field. AI Editing, Inline Generation, mobile browsers, and the iOS app show a dialog. Your choice applies across all conversations and these three features until credits become available through a purchase, monthly reset, or upgrade. Other models and features, and Free and trial plans, require a credit balance.

​
If Your Renewal Payment Fails

If a renewal payment fails for a plan purchased on the web, your monthly credits won’t refill until the payment goes through. In a desktop browser or the Mac app, open Settings > Plan or Usage and select “Update payment method” in the notice to check or change your card details. The same button appears when you reach a usage limit. This payment-failure notice isn’t available in the iOS app or mobile browsers. For a web subscription, check it in a desktop browser or the Mac app. After you change your card and return to Inki, it immediately tries to pay the outstanding renewal invoice. Once payment succeeds, your monthly credits refill and the notice disappears. Payment may not complete right away if you return without changing your card or if additional verification is needed. You can’t buy additional credits while the renewal payment is past due. If payment still doesn’t go through, the subscription will be canceled and you’ll return to Free.

​
Payment Method

On the web, pay by credit card through Stripe. In the iOS app, purchase a plan through the App Store. Light is also available in the English interface. Update the iOS app to version 1.0.18 or later. Check the purchase screen for plans and prices available in your App Store region. If an App Store plan you’ve purchased isn’t reflected in Inki, use “Restore purchases” with the Apple account used for the purchase. Restoration is available on the plan selection screen and in Settings. Manage or cancel an App Store subscription in Apple’s subscription settings.

​
App Store 7-Day Free Trial

In the iOS app from version 1.0.19, eligible Apple accounts can start Pro or Light with a 7-day free trial on monthly billing. When you’re eligible, the trial appears on purchase screens such as plan selection after signup and Settings > Plan. Annual plans and Max don’t include this trial. Both Pro and Light include up to 1,000 credits during the free trial. Afterward, the subscription renews automatically at the monthly price shown on the purchase screen. To stop it from renewing, cancel in Apple’s subscription settings. If you use up your trial credits, choose a plan on the credit-limit screen or under “Subscribe now” in Settings > Plan. Confirming ends your free trial, charges you immediately, and gives you the selected plan’s monthly credits. Review the price and credits before purchasing.
