Start for free
pay for how much the assistant works
On Free, the assistant buys with your card and pays Pix straight from the banks you connect through Open Finance. On paid plans, it also charges your customers and pays invoices through your Asaas account. The quota counts each payment, transfer, charge or boleto it executes for you; what you do in the dashboard doesn't count.

Who does what
- Lina: Pix, Bolepix and banks connected through Open Finance, on every plan
- Asaas: payment account, charges and boletos, on Basic and Pro
Went over the quota? On paid plans, before each extra operation the assistant asks if you authorize it: R$ 0.49 on Basic or R$ 0.29 on Pro, paid from an overage credit topped up with R$ 5.00 on your subscription card. On Free, it pauses until the month turns or until you subscribe.
Charge fees apart. Charges have their own fees, from the operator (Asaas, the payment institution), shown in the dashboard.
Only what goes through counts. A Pix you didn't approve or a declined purchase goes back to your quota. Companies with multiple approvers and API: talk to us.
Cora on WhatsApp
Already chatting with Cora?
she pays for you too
Send "Hi" to the official WhatsApp and connect your Strixs account. Through Cora your plan's quotas apply the same, and purchases and carts work even before you sign up.

What is Strixs?
A technology integrator that links your AI assistant to your card, to the accounts at any bank you use (through Open Finance) and to your payment account at Asaas, with spending rules you control.
Is Strixs a bank?
No. Payment accounts, charges and boletos are Asaas services. The connection to your banks and Pix straight from your account are provided by Lina, an institution regulated by the Central Bank of Brazil for Open Finance. Strixs is the technology that connects the assistant to them.
Can the assistant spend without me knowing?
No. It only pays within a rule you approved with your two-step verification code, and always below the account's daily limit.
Do I have to give my password to the assistant?
Never. It only asks for the two-step verification code when it needs your approval.
Which assistants work?
Claude, ChatGPT, Cora on WhatsApp and any MCP-compatible app, such as Claude Code and Cursor.
How much does it cost?
The Free plan includes 10 payments by the assistant per month, by card or Pix, and up to 2 connected bank accounts. Basic (R$ 24.90/month) includes 40 payments or charges and up to 4 bank accounts, and Pro (R$ 69.90/month), 80, with unlimited bank accounts, with charges and boletos through Asaas; beyond the quota, each operation costs R$ 0.49 on Basic and R$ 0.29 on Pro, paid from the overage credit (R$ 5.00 top-ups on your subscription card) once you authorize it. Through Cora, on WhatsApp, the same quotas apply. Charges have their own fees, from the operator (Asaas), shown in the dashboard.
Do I need a payment account to get started?
No. You create your Strixs account in seconds with WhatsApp or with e-mail and password. You activate the payment account at Asaas later, in the dashboard, when you want the assistant to pay and charge for you.
Is the app available in English?
Not yet: the Strixs dashboard is in Portuguese for now. Questions from outside Brazil are welcome on our Talk to us page.
