Tervezo gives your whole team a role in shipping software. Product writes the spec, AI builds to it, engineers stay in control.
Write the spec, set the criteria, hand it to an agent. Tervezo handles the rest — implementation, tests, and a PR ready to review.
# User Authentication
As a new user, I want to create an account
with email and password so I can access
the platform securely.
## Context
- Users arrive at /sign-up from the homepage
- Form collects: full name, email, password
- Email must be verified before first login
- Existing emails should show an inline error ## Acceptance Criteria
- [ ] Email field validates format on blur
- [ ] Password requires minimum 8 characters
- [ ] Duplicate emails show inline error message
- [ ] Successful sign-up redirects to /verify-email
- [ ] Failed attempts display a visible error banner
- [ ] Form is accessible and keyboard navigable # Assign spec to Tervezo agent
Spec: User Authentication
Repository: acme-corp/web-app
Branch: feat/user-auth
→ Agent will read spec and acceptance criteria
→ Agent will analyze existing codebase structure
→ Agent will implement changes to meet all criteria
→ Agent will write tests and verify each criterion
→ Agent will open a PR when all checks pass [tervezo] Reading spec: User Authentication

Anyone on the team writes detailed specs using AI chat. Product, design, engineering — one shared source of truth.
Define what done looks like upfront. Agents read your criteria and verify their own work before opening a PR.
Hand off a spec to an agent and watch it implement, test, and ship — without you translating requirements into tasks.
See every change, steer agents mid-task, and give feedback at any step. AI does the work; you keep the keys.
Agents open pull requests, respond to review comments, and iterate — all without you writing a single line.
Chain analyze → implement → test into multi-step workflows. Define inputs and outputs. Reuse across every sprint.
Run dozens of agent tasks simultaneously on isolated remote sandboxes. Your backlog moves at machine speed.
Use Linear issues as context when writing specs, or assign issues directly to Tervezo and let it ship them.
A collaborative editor built for product teams. Write specs in plain language with AI assistance, define acceptance criteria, and hand off to an agent with one click.

Build multi-step blueprints — define each step, configure inputs and outputs, and execute on remote sandboxes with full parallelism. Reuse blueprints across teams and projects without rewriting logic.
Connect your Linear workspace and use issues as context when writing specs. Or skip the spec entirely — assign an issue directly to Tervezo and let it analyze, implement, test, and open a PR.
From spec to PR, without the bottleneck. Start building with Tervezo today — your whole team ships, not just your engineers.
