Ship better AI, faster
The block-based prompt management platform for AI teams. Build prompts from structured blocks — role, context, instructions, guardrails — version safely, and fetch them in your apps with a single API call.
The problem
Prompts are the new source code.
Why are they still treated like strings?
As AI becomes core to your product, prompts define behavior, quality, and user experience. But most teams still manage them as raw strings hardcoded in source files.
Hardcoded in your repo
Every prompt change requires a code commit, PR review, and production deploy. Your AI features move at the speed of your release cycle.
No versioning or rollback
A bad prompt edit breaks production and there's no way back. You're flying blind with no history, no diffing, and no safe way to iterate.
Siloed to engineers
Domain experts, product managers, and content teams can't contribute to prompts. Their knowledge stays locked in meetings and docs.
How it works
Three steps from scattered strings
to production-grade prompts
Compose
Build prompts from typed blocks — role, context, instructions, guardrails, output format. Drag, drop, and reorder. Each block has a clear role, and they compile into a single production-ready prompt.
Version
Publish versions when ready. Development API keys return the latest draft. Production keys return the published version. Roll back instantly if something goes wrong.
Deliver
Fetch compiled prompts via a single API call. Pass variables at runtime for dynamic interpolation. Environment-scoped keys ensure you always get the right version.
const prompt = await fetch(
"https://api.promptot.com/api/v1/prompts/support",
{ headers: { Authorization: apiKey },
body: JSON.stringify({
variables: { user_name: "Alex" }
})
}
);
// Returns compiled prompt with variables resolved
// "You are a friendly support agent. The user's name is Alex..."
Features
Everything you need to manage
prompts at scale
Built for teams shipping AI products. Not another text editor with a save button.
Block-based composition
Break prompts into reusable, typed sections instead of managing one fragile string. See your prompt's structure at a glance and rearrange it in seconds.
role · context · instructions · guardrails · output format
Version control
Every change creates a version. Publish when ready, roll back instantly. Draft and published states keep development and production separate.
diff · rollback · changelog · publish
API-first delivery
Fetch compiled prompts with a single API call. Environment-scoped keys: development returns drafts, production returns published versions.
REST API · SDK · environment keys
Team collaboration
Engineers set the structure, domain experts fill in the content. Role-based access with admin, editor, and viewer permissions per organization.
roles · invitations · project-level access
AI-powered rewriting
Improve, expand, simplify, or custom-rewrite any block using AI.
Webhook notifications
Keep downstream systems in sync when prompts change. Signed payloads with automatic retries.
Guardrail blocks
Safety constraints as a first-class citizen of your prompt architecture.
Variable interpolation
Define {{placeholders}} and resolve them at runtime via the API.
Who it's for
Built for anyone shipping AI
Whether you're building a single chatbot or orchestrating a fleet of agents, PromptOT gives your team control over the prompts that power your product.
AI Application Developers
Building chatbots, summarizers, content generators, or search? Decouple your prompts from code. Iterate on prompt quality without redeploying your app.
Ship prompt improvements in minutes instead of waiting for your next deploy
Agent Engineers
Designing autonomous agents with multi-step reasoning, tool use, and goal-oriented behavior? Structure your system prompts with typed blocks for reliability.
Define agent personas, guardrails, and output schemas as composable blocks
Agentic Workflow Builders
Orchestrating multi-agent systems with LangChain, CrewAI, or custom frameworks? Manage the prompts that power each step of your pipeline.
Version each agent's prompt independently, deploy workflow updates without code changes
ML / AI Engineers
Evaluating prompt quality, tracking cost, or optimizing token usage? Use PromptOT's versioning and playground to measure the impact of every prompt change.
Catch regressions before they reach users
Product Teams
Need to iterate on AI features without waiting on engineering? Edit prompts in a visual editor. Publish when ready. Let engineers set the guardrails.
Ship AI improvements on your schedule, not the release cycle
Domain Experts
Working in legal, healthcare, education, or finance? Your knowledge shapes AI behavior. Write prompt content in a structured editor without touching code.
Turn subject matter expertise into production prompts without engineering bottlenecks
Integration
One API call. Any language.
Fetch your compiled prompt with variables resolved. Works with every LLM provider — OpenAI, Anthropic, Cohere, or your own models.
curl -X GET \"https://api.promptot.com/api/v1/prompts/customer-support/compiled" \-H "Authorization: Bearer pk_live_abc123..." \-H "Content-Type: application/json" \-d '{"variables": {"user_name": "Alex","plan": "Pro","tone": "friendly"}}'
