By creating an API key or subscribing, you agree to these terms. If you do not agree, do not use the service.
Budget AI is an OpenAI-compatible API gateway. It forwards your requests to third-party AI model providers and returns their responses, failing over between providers automatically. We do not train or host the underlying models.
Capacity is sourced from the free and low cost tiers that those providers publish. What you pay for is the delivery layer we put on top: pooled routing across several providers, real-time rate limit tracking, automatic failover, a single OpenAI-compatible endpoint, one key and one bill. Because the underlying capacity is not exclusively ours, availability of any individual provider can change without notice, which is why the service is offered without an uptime guarantee.
Each plan carries a published per-minute and per-day request limit and a maximum response size. Requests beyond your limit receive HTTP 429. Paid plans are sold in a limited number of seats; when a tier is full it cannot be purchased until a seat frees up.
You may not use the service to generate content that is illegal, to attempt to breach or overload the service or its upstream providers, or to circumvent rate limits — including by creating multiple accounts or keys to obtain additional free quota. Requests are screened against a content policy filter, and requests that match are refused with HTTP 403.
We may suspend or terminate a key that violates these terms. Where a paid subscription is terminated for a violation, no refund is due.
The service is provided on an "as is" and "as available" basis with no uptime guarantee and no service level agreement. It depends on third-party providers whose availability we do not control. Automatic failover reduces the impact of a single provider outage but cannot eliminate it.
To the maximum extent permitted by law, our total liability for any claim relating to the service is limited to the amount you paid in the three months preceding the claim. We are not liable for indirect or consequential loss, including lost profits or lost data.
Model output may be inaccurate. You are responsible for reviewing it before relying on it.
We may change these terms, pricing, or plan limits. Material changes will be reflected on this page with a new "last updated" date. Continued use after a change constitutes acceptance. A price change never applies to an existing subscription period you have already paid for.
Prompt and response content is forwarded to the upstream provider that serves your request and is not stored by us. We do not keep a database of your conversations, and we do not use your prompts to train anything.
Two qualifications you should understand:
If you use the browser chat at /chat, your conversation history is stored in your own browser (localStorage) and never sent to us for storage. Clearing your browser data deletes it permanently.
We set one cookie, a signed HttpOnly session cookie, after you log in with an email code. It is strictly necessary to keep you logged in. There is no advertising or analytics tracking on this site.
We do not sell personal data. Data is shared only with the processors required to run the service: the AI providers that serve your requests, Stripe for payment, and Resend for transactional email.
You can request a copy of the data we hold about you, or its deletion, by emailing us. Deleting your data revokes your API keys and cancels any active subscription. We respond within 30 days.
You can cancel at any time by emailing us. Cancellation stops future billing. Your plan stays active until the end of the period you have already paid for, after which your key reverts to the free tier and your seat is released to someone else.
Approved refunds are issued to the original payment method through Stripe, normally within 5–10 business days.
To cancel or request a refund, email the address below from the address on your subscription and say which you want. That is the whole process — there is no form to fill in.
Budget AI is operated as a sole trader. For support, billing, cancellation, refunds, or any privacy request:
