Questions, answered
What counts as a request?
Credits are priced at one cent each at the standard rate, and plans and their top-ups give you more credits for your money. A request is each time Sessi or a colleague sends a prompt to your AI tool and gets a reply back. Today one credit covers two requests, the same on every plan. One job can take several requests. You can see what each one used.
Do I still need my own AI tools?
Yes. Plans pay for Sessi and her team, not the AI model. SESI works with Claude Code, Codex, Cursor, Copilot, Grok, Kimi Code, Ollama and more, so keep paying for the one you use.
Do credits reset or expire?
Plan credits arrive every month, and at the next month any left reset, on monthly and annual billing alike. Top-up credits don’t reset or expire while your account is open, except as our Terms provide. Bonus and reward credits don’t reset either, but we can withdraw them for abuse or other serious misconduct. Bonus credits that come with a plan, and extra credits it adds to packs, end if you cancel it within 30 days of a payment, and any you used come off the refund. Your plan’s credits are used first, then starter and reward credits, then your top-ups, oldest first, and your plan’s bonus and extra credits last. Our Terms of Service govern credits.
How do annual plans work?
You pay once a year for a better deal, and your credits still arrive every month. Any left at the end of a month reset.
What if I cancel?
Cancel any time on your Billing page. Within 30 days of a payment, your plan stops right away and we refund what you didn’t use: this month’s unused plan credits and, on an annual plan, the months still to come. The plan’s bonus credits end with it, along with the extra credits it added to your packs, and any of those you’ve used come off the refund. After 30 days there’s no refund: your plan just won’t renew, and you keep it until the time you paid for runs out. Your other top-up credits stay yours while your account is open. Refunds follow our Terms of Service.
Can I get a refund on a credit pack?
Yes, within 30 days of buying it, for that pack’s credits you haven’t used, not counting any extra credits your plan added. After that, packs aren’t refundable. Bonus and reward credits aren’t refundable. Refunds follow our Terms of Service.
How does auto top-up work?
Turn it on in Billing, pick a pack and set a monthly budget, or choose no limit. When your credits fall below 100, or a job needs more than you have, we charge your saved payment method for that pack and email a receipt. It can run many times a month, including while agents work unattended. It pauses at your budget, and for the day if a large amount is charged at once. Credits it buys are top-up credits, which don’t expire while your account is open; any extra credits your plan adds end if you cancel the plan within 30 days of a payment. Turn it off any time on your Billing page. Our Terms of Service apply.
What happens if I run out?
Work pauses until you add credits. Top up with a credit pack at any time, or turn on auto top-up to keep going. Builder and Pro get more credits in every pack.
What does SESI run on?
SESI runs on Apple silicon Macs and on 64-bit Windows.
