AI agents that turn specs into production code
Tervezo gives your whole team a role in shipping software. Product writes the spec, AI builds to it, engineers stay in control.
Spec to shipped, end to end
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

Tervezo closes the gap between what product wants and what engineering ships — by giving everyone a structured role in the process.
Collaborative Spec Writing
Anyone on the team writes detailed specs using AI chat. Product, design, engineering — one shared source of truth.
Acceptance Criteria Built In
Define what done looks like upfront. Agents read your criteria and verify their own work before opening a PR.
AI Agents That Build to Spec
Hand off a spec to an agent and watch it implement, test, and ship — without you translating requirements into tasks.
Engineers Stay in Control
See every change, steer agents mid-task, and give feedback at any step. AI does the work; you keep the keys.
Automated PRs and Reviews
Agents open pull requests, respond to review comments, and iterate — all without you writing a single line.
Reusable Blueprints
Chain analyze → implement → test into multi-step workflows. Define inputs and outputs. Reuse across every sprint.
Unlimited Parallel Execution
Run dozens of agent tasks simultaneously on isolated remote sandboxes. Your backlog moves at machine speed.
Native Linear Integration
Use Linear issues as context when writing specs, or assign issues directly to Tervezo and let it ship them.
Anyone can write a spec. AI does the rest.
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.

Set the workflow once. Run it a hundred times.
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.
Assign an issue to Tervezo. Ship it.
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.
Your backlog isn't a people problem. It's a workflow problem.
From spec to PR, without the bottleneck. Start building with Tervezo today — your whole team ships, not just your engineers.
