Connect Claude + your repo
Connect this Mac. Your subscription. No model we ship.
The company for the Claude and Cursor you already pay for.
Bring Claude or Cursor. You already pay them. Hire employees here. They work in those tools, on your machine, on your subscription. SessionTwin is the office — not another model bill.
Your Claude / Cursor
Tokens stay with you
We sell the company
Real login UI · floating cards are labeled illustrations · D1 prove closed 2026-08-21 (one live loop; the night still open)
Uses the tools you already pay for — we ship no model of our own
- Claude Code
- Cursor
- GitHub
- Your machine
Cursor stays Blocked until LIVE-PROVEN. Codex and Gemini are ungoverned — not hireable.
Live product · sessiontwin.ai/login
One place for what needs you. Everything else runs.
Hire AI employees. They drive Claude on your repo. You only show up for the exceptions — approvals, conflicts, first-time calls. The Brief is evidence, not twenty terminals to audit.
One approval surface
Employees drive Claude
Empty means Not staffed
Company OS UI · labeled fiction until your workspace fills it
Connect this Mac. Evidence when verify lands.
Connect this Mac. Use the Claude subscription you already have. We record the chain — we never become the model vendor, and we never train on your answers.

Evidence, not chat
Ledger · live at sessiontwin.ai/web/ledger
Don’t take our word. Attack the log.
Every step is signed into a tamper-evident ledger. Try to edit, delete, or re-sign an entry. Your browser catches it — not our server. If we can’t prove it here, we don’t deserve the night.
Frozen before work
Agent can’t grade itself
You check the math
Three steps
From “I hope it worked” to a signed Brief
02
Freeze what “done” means
Write the checks first. Hire an employee onto Claude. Then leave the bar alone.
03
Open Needs You
A separate process signs the verdict. You only wake for what has no rule yet.
Built for people who got burned by a confident lie.
The worker never becomes the governor. If we can’t prove a claim, we say so.
Your machine
Code stays on your disk
Runs with your Claude subscription. Credentials stay local. We keep the evidence trail — not your keys.
Verifier
Homework the author can’t grade
The process that wrote the code has no tool that calls the verifier. Dirty workspaces can’t fake a pass.
Twin
It copies your judgment — not a model
Re-reads answers you already gave. Delete one and it unlearns. Nothing is trained on you.
Straight answers
What do I actually get?
A company: hire employees who work in the Claude or Cursor you already pay for. One Needs You. One Brief. Tokens stay on your subscription. We sell the office, not the model.
Is this another coding agent?
No. We ship none. SessionTwin sits above Claude, Cursor, and GitHub. The moment we favor a model we stop being the referee.
Can I really leave it overnight?
Not yet. The loop is LIVE-PROVEN — it closed once on production, 2026-08-21 — but a qualifying night has never run, and we won’t pretend it has. Once is not a night; the night is the remaining gate. You may still open Claude or Cursor yourself.
Can I use Cursor?
Cursor stays Blocked until LIVE-PROVEN. Hire Claude Code today. Codex and Gemini are ungoverned — not hireable.
Do you train on my work?
No. The Twin re-reads your past answers; it does not train a model. Delete an answer and it unlearns.
How do I start?

Not true yet: a qualifying unattended night. The loop closed live once on production (2026-08-21, n=1, about a minute) — once is not a night. The scheduler is live: pg_cron inside the production database ticks advance every 5 minutes. Missions run when a worker is on shift or when the founder runs one — the shift is founder-controlled. Paying users stay blocked on the founder — this page invents no customer count.
