Logic64 AI assistant software architectLogic64 AI Software ArchitectStay Aligned

Logic64 is the AI software architect for spec-driven development.
It locks the architecture first: stack, service blueprints, API contracts, data models. Everything lands in one workspace your AI coding assistant can't drift from.

A live look at the Studio mid-flight. Logic64 designs the architecture, locks the decisions, and writes the constitution before you touch a file.

AI can write the code. It shouldn't invent the architecture.

Logic64 turns project requirements into a reviewed architecture — then derives the shared instructions every coding agent follows.

Requirements

Capture what the system must do.

Product intent
User flows
Key constraints

System Design

Review the architecture before implementation.

Connected decisions
Reviewable structure
Approval first

Agent Instructions

Derive the working context for every agent.

Shared across tools
Derived from architecture
Keeps agents aligned

Without Logic64

Architecture by assumption

Agents fill in the blanks
Decisions drift across sessions
The system changes without a shared plan

With Logic64

Architecture by design

Requirements shape the architecture
Decisions stay connected
Every agent builds from the same source

The difference isn't who writes the files. It's what makes those files trustworthy.

Your stack, decided.
Not assembled.

Describe what you're building. Logic64 reads scale, constraints, and surface — then locks the exact technologies that fit.

No guesswork

No over-engineering

Locked before code

Production-grade workspaces. No configuration required.

Every stack. Every scale. Zero configuration.

Agencies & Startups

Schema locked. Auth defined. Billing scoped — before line one. Spec-driven from the first commit.
