Frequently asked questions.
What Letco is, how it verifies AI-generated software, and how it fits your team.
What is Letco?
+
Letco is an autonomous, quality-driven AI software development platform that builds production-ready software end-to-end while humans stay in control at every step. Unlike AI tools that stop at generating code, Letco independently verifies that what it built actually works and keeps it aligned with the original specification.
How does Letco make sure AI-generated code actually works?
+
Letco runs a closed four-stage pipeline — Analyze, Implement, Execute, Control — with an automated repair loop. An adversarial “definition of done” auditor, separate from the code's author, checks every result against the documented requirements, and unresolved findings automatically spawn linked follow-ups, so verification happens without human triage at merge.
Which AI models does Letco support?
+
Letco is multi-model: it orchestrates Claude, Gemini and Codex, and you can swap models per task. It is built on AI subscription CLIs rather than pay-per-token APIs, which gives flat, predictable cost and lets you bring your own subscriptions (BYOD).
Who is Letco for?
+
Letco is a platform for the whole software team, not just developers. Product owners, product managers, analysts, developers and testers all work from one living project documentation across the complete software development lifecycle (SDLC).
How does Letco stop code from drifting from the spec?
+
Letco pins the project specification as a read-only source of truth that is deterministically injected into every step of the orchestration. Because the spec is enforced rather than merely referenced, the build stays aligned with the original intent instead of drifting over time.
Is Letco secure and enterprise-ready?
+
Yes. Letco uses AES-256-GCM encryption, a six-layer authentication stack (JWT, OIDC, NATS), a zero-knowledge architecture where keys never leave the user's control, strict per-session isolation, and a full immutable audit trail.
How is Letco different from AI coding assistants or IDE copilots?
+
AI coding assistants are developer tools bolted onto an IDE that stop once code is generated. Letco is a full-team web platform that starts from a structured process, orchestrates the entire SDLC and independently verifies the result — solving “we can trust it works,” not just “the code got written.”
How does Letco's cost model work?
+
Letco is built on AI subscription plans instead of pay-per-token APIs, so cost stays flat regardless of how many tokens are generated. Customers can bring their own model subscriptions or buy through Letco, with fully transparent, per-session cost tracking.
