Pick by usage shape.
Work items, sessions, machines — not tokens.
Early access is approval-gated. After submitting a request, we review and follow up directly. Access is not instant.
HOW LIMITS WORK
Pay-as-you-go
Burst use, no subscription.
Pay-as-you-go: $300 initial credit, $50 recharge. No subscription commitment. Suitable for burst use — resolving a backlog, a team trial, or infrequent heavy use.
Team plan
How Team works.
- 5 machines share the same case list and memory.
- Each machine has its own local workspace. Cases are shared via export/import or a shared filesystem mount.
- Case export (JSON and markdown) is available on the Team plan. Import from another Zero instance is supported.
- Session limits are shared across the team — 400 sessions/week total across all machines.
FAQ
Common questions.
What counts as a session?+
One AI-assisted work run on a case. Starting a new planning pass, applying a fix, or running a regression test each constitutes one session.
Is access immediate after signing up?+
No. Access is approval-gated. We review each request and follow up directly. Approval typically takes 1–2 business days.
Can I change my plan?+
Yes. Contact us after approval and we can adjust your plan.
What happens when my session limit is reached?+
You can still view and manage cases. New sessions are queued until the next billing period or you upgrade.
Is there a free trial?+
Not at this time. Early-access pricing is intentionally low.
What is proof and why is it required?+
Proof is verified evidence (test logs, traces, diff files) that you attach to a case before it can be marked RESOLVED. It is enforced by the system — not optional.
How does Zero use AI?+
Zero uses AI to run planning, implementing, and verifying sessions on your Work items. The AI reads your code context, forms a hypothesis, proposes a plan, and executes code changes. You approve the plan before any code runs. AI usage is built into the subscription — no separate AI billing.
HOW ZERO COMPARES
| Capability | Issue tracker + AI chat | With Zero |
|---|---|---|
| Session tracking | None — no record of what was tried | Every session logged: hypothesis, diff, tests |
| Proof enforcement | Voluntary — up to the engineer | System-enforced — RESOLVED blocked until proof |
| Regression recall | Manual search or memory | Automatic: search resolved cases before you dig |
| Case structure | Unstructured comments and notes | Structured cases with state machine |
| Code stays local? | Depends on AI tool | Always — code never leaves your machine |
If you already have a process that logs sessions, enforces proof, and recalls past resolutions — Zero adds little. If you don’t, Zero gives you all three.
