  • Unified credit pool — move credits between modalities
  • Commercial license on everything you generate

Agents that don't just chat — they ship.

Hand a task to an autonomous agent: research a market, refactor a repo, draft and schedule a campaign. Agents route themselves to the right model per step and report back with receipts.

  • Task delegation with per-step model routing
  • Full audit trail: which model did what, for how much
  • Webhooks and API — plug agents into your stack

People who cancelled five subscriptions

★★★★★

"I was paying for ChatGPT, Claude, Midjourney and two more. Sandbox replaced all of them on day one, and the side-by-side comparison actually changed how I write."

★★★★★

"We benchmark every model against each other before shipping prompts to production. That used to mean five accounts and a spreadsheet. Now it's one workspace and one invoice."

★★★★★

"The agents are the real deal. I delegated a competitor teardown and got a sourced report back in 20 minutes — with a receipt for every model call."

FAQ

Straight answers

Yes. Just download and install — no card, no email, no account to create on the website. You land straight in your workspace with full Pro-level access and 300 trial credits for 3 days. If you want to keep going after that, a payment link appears inside the app; nothing is charged before then, and nothing is lost if you don't.
Right now Sandbox is a Windows 10/11 app only — that's where we've focused engineering effort to get the experience right. A macOS build is actively in development; join the waitlist on the pricing page and we'll email you the day it ships. There's no timeline for Linux yet.
Windows 10 (64-bit, 21H2+) or Windows 11, a dual-core 2.0 GHz+ processor, 4 GB RAM, 500 MB free disk space and a broadband connection. The app itself is lightweight — all model inference happens in the cloud, so it runs fine on modest hardware.
20+ frontier and open models: GPT-5, o3, Claude Opus & Sonnet, Gemini 2.5 Pro, Llama 4, Grok, DeepSeek, Mistral, plus image (Midjourney, DALL·E, Imagen, Stable Diffusion), voice (ElevenLabs), video (Runway) and music generation. New models ship within days of public release.
We buy enterprise inference capacity directly from OpenAI, Anthropic, Google, Meta, xAI and others, and host open models on our own GPU fleet. Your prompts go to the official APIs or our own clusters — the same compute you'd rent yourself, pre-paid in one subscription.
Zero-retention API agreements with every provider: your prompts are never used to train models. EU customers can pin their workspace to our Frankfurt region (Ultra plan). SOC 2 Type II audited; GDPR DPA signed at checkout.
Ultra includes 3 seats with shared prompts, shared agents and a consolidated bill. Larger teams use Custom plans: SSO/SAML, unlimited seats, per-member spend limits, audit logs and VPC deployment.
You can buy top-up credits anytime ($10 = 400 credits), or set a soft cap so heavy jobs pause instead of charging. Unused Pro credits roll over up to one month. You'll never get a surprise invoice.
Any time, in one click, no exit interview. Your conversations and generations stay exportable for 90 days — everything you made is yours, licensed for commercial use.
