On-demand usage picks up where your monthly credits stop, at $5 per 1M credits, billed in arrears on your next invoice. It is off until you turn it on, and you set the monthly spending limit it stops at — on the account page, not here.

FAQs

No. Managed AI is included on every plan, with no API key and no card, just a free account. That gets you 150 AI actions a day and 1M credits a month. Pro multiplies that allowance, and Ultra adds the frontier model (Sakura 2 High).

Allowance: 4× the daily AI actions, 600 instead of 150, and 4× the monthly credits, 4M instead of 1M. It also unlocks on-demand usage, so a big board doesn't stop at the end of the month. The models are the same as Free's; Ultra is what adds the frontier model (Sakura 2 High).

Ultra adds the frontier model (Sakura 2 High) and 8× the allowance, so 4,800 AI actions a day and 32M credits a month instead of 600 and 4M. Start on Pro. Move up when you want the frontier model for a dense board, or when you're turning on on-demand usage every month — Ultra is cheaper per credit.

Every plan includes a monthly allowance of credits. On Pro and Ultra you can turn on on-demand usage to keep working once it's gone, at $5 per 1M credits, billed in arrears on your next invoice. It's off until you turn it on, and you set a monthly spending limit that we stop at. No surprise invoices.

Each AI action uses credits based on the context it reads and the answer it produces. Cached context counts at 10%, so iterating on the same board is far cheaper than starting fresh. Manual editing and exports are never metered.

A rolling 30-day window starts with your first managed AI request. Your full quota returns when the window ends.

The editor and exports keep working. AI pauses when you reach your plan's daily actions or its monthly credits. The daily figure is 150 on Free, 600 on Pro, 4,800 on Ultra. On Pro and Ultra, on-demand usage carries you past both.

Your first Pro subscription includes 5 days free, monthly or yearly. A card is required, but cancel before the trial ends and you pay nothing. One trial per account, and it's Pro's alone. Ultra is billed from day one.

Yes. Use the Stripe billing portal to move between Pro and Ultra, switch between monthly and yearly, update your card, download invoices, or cancel. A canceled plan stays active through the paid period, then you drop back to Free, which still includes the editor and managed AI.
