Questions
The short answers
- Do I need an account for Free?
- No. Download it, open a project, and go. Slip reads the Claude Code, Codex, or Grok sign-in you already have and never asks for one of its own.
- What does “3 agents at once” mean?
- Three cards with a running agent at the same time. Cards themselves are unlimited: keep every project, every brief, every conversation. Only the fourth simultaneous agent waits for a slot, or for Pro.
- How does Slip know I'm Pro?
- You sign in inside the app (Settings → Slip Account), with Apple or a code by email. Slip fetches a signed statement of your plan and checks the signature itself. That's all it ever sends or receives about you: no transcripts, no paths, no prompts.
- What's a founding member?
- Anyone who signs in during the beta, before the limit is turned on. Founding members get six months of Pro free and keep the badge.
- Who's the seller?
- Ctrl Alt Go, the company behind Slip. Payments are processed by Stripe: your card never touches our servers, and your receipt, invoices, and cancellation live in Stripe's billing portal.
