●  For product and engineering teams building with AI

AI made building software fast. REEZN makes it right.

REEZN is how teams keep quality in the loop when AI does the building: every feature starts as an AI-drafted blueprint your team reviews and approves, shaped by your standards, your guardrails, and the right sign-offs, before a line of code is written.

The blueprint

Software built from a one-line prompt gives you slop. Software built from a blueprint gives you quality.

Every blueprint answers seven questions your team would otherwise have to guess at, before anything gets built. It's the shared reference everyone, including your AI tools, works from, and it's why the result holds up.

01What we're building
The requirements, restated clearly and traced back to what was asked for.
02The moving parts
The key concepts involved: what they are, how they relate, what rules they follow.
03Why this way
The chosen direction and the alternatives that were considered, so decisions don't get re-litigated.
04How it fits
Where the new work lives and how it connects to what already exists.
05What happens when
How it behaves day to day, including what happens when things go wrong.
06Your team's standardsSet once, applied everywhere
Your organization's ways of working, applied automatically to every plan.
07Your guardrailsSet once, applied everywhere
The hard limits: privacy rules, usage caps, the things that must never be crossed.
A blueprint under review. Comments block approval until they're resolved.

Organizational memory

Plan #50 is written with everything plans #1–49 established.

Every approved blueprint, norm, and document adds a little more to your organization's own knowledge graph: the services, the concepts, the rules, the people. The AI consults it while drafting, pulling in just the entities that matter to the plan at hand, so context compounds instead of getting re-explained.

When a new plan is drafted, REEZN pulls in just the entities and rules that matter to it from your organization's graph.

Trust & control

Engineering rigor used to be a luxury. Not anymore.

Documented standards, enforced patterns, reviewed plans: practices that were once reserved for companies with time and headcount to spare. AI changes that. REEZN puts those practices within reach of every team, so AI makes your software better, not sloppier.

A living library of norms & patterns
Your technical norms, practices, and proven patterns: captured once, kept current by the team, and woven into every plan automatically. No more tribal knowledge.
Safety guards
Hard limits that every plan must respect: privacy boundaries, usage caps, things that are simply off the table, no matter what the AI suggests.
A complete history
Every plan, every revision, every approval: timestamped and attributable. The answer to 'why was it built this way?' is always one click away.
The right sign-offs
Product confirms the plan says what they meant. Reviewers confirm it's right to build. Everyone approves what they're best placed to judge.
Questions teams ask first
Does REEZN replace Cursor, Claude Code, or Copilot?
No. Your engineers keep the tools they already use. REEZN is the layer above them: where a feature gets defined, agreed, and verified. The approved blueprint can be handed to any coding agent, or REEZN's own agent can implement it and open the pull request.
Where does my code and data go?
You bring your own Anthropic, OpenAI, or Google API key, so prompts go to your provider under your key and nothing is retained for training. Repository access uses tokens you scope yourself, and your plans, norms, and decisions stay in your organization.
What does the free plan include?
The full planning workflow for a small team: AI-drafted analyses and blueprints, review gates, and versioned approvals, for up to 3 seats, 1 project, and 10 features a month. No card, no trial clock.
Doesn't AI just make things up?
It does, and REEZN puts that where it belongs. AI fills every gap in a requirement with a confident guess: fatal in merged code, useful in a draft a human reads. The blueprint states its assumptions in plain sight and flags what the ask never specified, so a reviewer confirms or corrects each guess in seconds instead of finding it in production.
How long until we see value?
Minutes. Describe a feature in plain language and you'll be reviewing a structured analysis shortly after, edge cases included. Most teams get it at the first blueprint: the questions nobody had written down are suddenly in front of the team.
