About PromptOT
Prompts are the new source code
PromptOT treats prompts as first-class infrastructure. Compose them from typed blocks, version them safely, and deliver them to your applications through a clean API.
The Problem
Prompts deserve better than this
Teams are shipping AI features but managing prompts like config files from 2005. Hardcoded strings, no versioning, no collaboration. It doesn't scale.
Scattered across codebases
Prompts live as hardcoded strings in application code, duplicated across services with no single source of truth.
No versioning or rollback
Changing a prompt means redeploying your app. No history, no diffs, no way to roll back when something breaks.
No collaboration
Product managers, domain experts, and engineers can't collaborate on prompts without touching code.
Our Vision
Prompt infrastructure for AI-native teams
We're building the platform that lets teams compose prompts from typed blocks, version them safely, and deliver them via API — so your prompts evolve as fast as your product.
Structured composition
Build prompts from typed blocks — role, context, instructions, guardrails, output format. Each block has a clear purpose.
Version control built in
Every change creates a new version. Compare diffs, roll back instantly, and publish only when ready.
API-first delivery
Fetch compiled prompts via a single API call. Variable interpolation happens server-side. Your app stays clean.
How We Think About It
Prompts as structured documents
Instead of treating prompts as opaque strings, PromptOT models them as structured documents composed of typed blocks — each with a clear purpose, independently editable, and automatically compiled with variable interpolation.
The Team
Built by developers, for developers
We're a small team obsessed with developer experience. We've spent years building dev tools and saw firsthand how painful prompt management becomes at scale. PromptOT is the tool we wished existed.
