You hold the helm.

Ship 10x faster.
Break nothing.

You design. The AI agents crew executes.
Nothing merges without your signal.

The problem

Your AI agents are fast.
But fast without guardrails is dangerous.

Parallel AI agents multiply your output. They also multiply your risk. Without orchestration, speed becomes your most expensive liability.

AI ships bugs at scale

Your agents generate 500 lines in 10 minutes. But Agent 2's auth refactor broke Agent 1's API contract. Nobody caught it until production. The faster AI codes, the faster bugs compound.

Tmonier validates cross-agent changes before anything merges.

You became the integration layer

5 agents, 5 worktrees, 5 diffs to review. You're the only one who sees the full picture — and you're doing it manually, across tabs, with no tooling. AI was supposed to save you time. Instead, you're a full-time code reviewer for robots.

Tmonier gives you one dashboard, structured checkpoints, and conflict detection.

Nobody owns the architecture anymore

Each agent optimizes locally. None of them know your service boundaries, your naming conventions, or what was decided last sprint. The codebase drifts — not in one session, but across dozens. Death by a thousand AI commits.

Tmonier enforces architectural memory across every agent, every session.

How it works

From spec to merge in three steps

01

You define the spec

Describe what you want built. Tmonier drafts a technical spec — tradeoffs, boundaries, contracts — and decomposes it into parallel tasks. You review and approve the plan before any code is written.

02

N agents build in parallel

Each agent works in an isolated worktree on its slice of the feature. Tmonier monitors all of them: progress, conflicts, drift. You see everything from one dashboard. Any agent can raise a question — only you answer.

03

You review everything in one place

All changes validated against each other. Architectural consistency checked. Conflicts surfaced. You review one unified diff, not five. Approve once, merge once. Done.
