A credit is the unit your usage is billed in, and you are charged per action, not per word.
That is the whole model, and it is chosen so your bill does not move when we change a model behind the scenes. A faster or cheaper model never changes your price.
Each kind of action has its own fixed price in credits, and those prices differ a lot between them. They are not one credit each.
What costs credits
These are the prices in effect today. They are set per workspace and can change; your invoice always carries the ones you were actually charged.
| action | credits | what it is |
|---|---|---|
| Chat turn | 120 | one answer from Nisa in Slack or chat |
| Voice message | 150 | one spoken message she listened to and transcribed — see Voice messages |
| Skill run | 60 | one scheduled or manual run of a Skill |
| AI visibility run | 400 | one run of the AI-visibility Skill: it checks how AI answer services mention you |
| Heavy run | 60 | a run that needed a sandbox — building something, publishing |
| Page render | 10 | one web page opened in a real browser to read what a plain fetch could not |
| Web search | 4 | one search against the live web |
| List search | 240 | one wide search for a list you asked for ("all the press outlets in ..."): the many searches behind it, and up to two more on the parts that came back thin, are one action, never billed as single web searches |
| Building a Skill | not charged yet | one Skill created from a description |
| Contact lookup | not charged yet | one enriched contact from a people database |
| Contact search | depends on the record | a search of a people database is free; opening an email address or a phone number is charged per record, and the price is shown before you confirm |
| Outbound email | not charged yet | one email sent to somebody outside your workspace |
| Outbound campaign | not charged yet | one outreach campaign started |
| Purchase | not charged yet | one thing bought for you, after you approve it |
| Browser time | not charged yet | each second Nisa spends operating a website for you in a browser, where available |
| Phone call | 200 per started minute | each started minute of a call Nisa makes to a business for you, where available, and of a call that business makes back to take a message for you; the card names the most a call can cost, and a call nobody answers costs nothing |
| Watch check | 1 | one look at a page or an app a watch re-reads for you (every 30 minutes unless you ask for another pace, at most every 10). A check through the browser is billed as Browser time instead, never both. When a check finds a change worth acting on, her answer is a chat turn |
A spoken message costs both lines. The 150 pays for listening; the answer she gives you is a chat turn on top, so a voice message you get a reply to is 270, against 120 for typing the same thing. That is not a surcharge for speaking — transcription is a second model call, and it is billed as its own action so you can see it rather than find it buried in a bigger number.
Why a chat turn costs more than a Skill run, and the reason is worth knowing: when you talk to Nisa she reads your company Brain to answer you. A Skill already knows what it is looking at.
Why a phone minute costs 200: a call runs on a phone line and a voice service that together cost about $0.25 a minute. At about $0.0025 a credit, 200 credits are $0.50: the price carries those costs and is not where we make our margin. A business that calls back about one of your calls is billed to you the same way, per started minute; a caller we cannot match to exactly one customer is never billed to anyone.
Why the AI visibility run has its own price: it checks several AI answer services, which costs far more than an ordinary run.
The rows marked "not charged yet" are exactly that — the meter runs and records them, the price is simply not set. When a price is set it appears here first.
What does not cost anything
Reading your own Brain in the web app. Opening a report she already produced. Correcting a fact. Rejecting a card.
How long credits last
Two rules, and the difference between them is who paid for what.
Credits included in your plan arrive each billing period and are good for two months from the day they arrive. Unused ones roll over — there is no cap on how many, only on how long. A quiet month therefore carries into the next one instead of vanishing, and at a steady pace you will never be holding more than two periods' worth anyway.
The credits you receive when you sign up are good for 30 days. They are your first month, not a reserve: use them to find out what she does for you, and the plan takes over from there.
Credits you buy on top of your plan (a power-up) expire 12 months after purchase. They survive cancelling: if you stop your plan, the plan's credits go with the plan, and anything you bought separately stays where it is until its 12 months are up. Power-ups bought before 15 October 2026 keep the no-expiry terms they were sold with.
We always spend whichever credits expire soonest. Your plan's allotment lasts two months, so it is normally used before anything you bought; a power-up near the end of its 12 months is used before a fresh allotment, so it is not left to lapse.
Where you can see what is left
In the app, bottom left. The sidebar carries your balance under your profile, and under it the line that actually answers the question: roughly how many more questions it buys, or — on the free plan — how many of today's actions you have left. It refreshes on its own.
By asking. "How many credits do I have left?" is a question Nisa answers from the ledger, not from memory. She can also tell you what is about to expire and what you have been spending it on.
If we cannot read it, we say so. A balance we could not load shows as nothing at all, never as a zero — a zero would read as "top up now", and we are not going to tell you that because our database hiccuped.
On the free plan, the day is the limit
The free plan is bounded by a daily allowance, not by your balance. You get a set number of actions each day, and it refills every day — so running out is never permanent, and you are never asked to pay to get today's work finished tomorrow. Nisa tells you what is left when it matters, and you can always ask her.
Your credits still tick down and the counter still shows them; they are simply not what stops you. The balance becomes the limit when you are on a paid plan.
When you run out
Nothing is charged for an action that did not happen. A Skill that failed to start because a connection was missing costs nothing, and a card you rejected costs nothing. A failed run is not on your invoice.
If your balance reaches zero, scheduled Skills stop and Nisa tells you — she does not silently skip a morning and let you assume it ran.
