Full platform

Everything you need to manage AI prompts

From creation to deployment — organize, version, test, scan, share, and integrate your prompt library with one platform.

Create and Compose

Build prompts with the AI-assisted COMPOSE wizard, import from files, or start from a blank editor. Three creation modes — Blank, Guided, and AI Consultation — meet you where you are.

  • COMPOSE wizard with AI-assisted prompt building
  • Import prompts from JSON, Markdown, or plain text
  • 8 distinct prompt types for different use cases
  • Markdown editor with live preview
  • Remix and fork public prompts from the community

Organize and Discover

Collections group related prompts together. Tags let you slice across collections. A command palette gets you anywhere in two keystrokes. Bulk operations handle the tedious work.

  • Collections for hierarchical organization
  • Tags for cross-cutting categorization
  • Full-text search across titles and content
  • Favorites for quick access
  • Bulk tag, move, and delete operations
  • Command palette for keyboard-driven navigation

Templates and Variables

Turn any prompt into a reusable template by adding variables with double-brace syntax. Define types, defaults, and constraints. Render with validated inputs from the web UI, MCP, or API.

  • Variable types: text, number, select, multiline, boolean
  • Schema validation with defaults and constraints
  • Template rendering with type checking
  • Export rendered output for use in any AI tool

Conversations New

Chat with AI models using your prompts as system instructions. Import conversations from Claude and ChatGPT. Link chats to prompts for a complete feedback loop between authoring and usage.

  • Multi-turn conversations with streaming responses
  • Import from Claude, ChatGPT, JSON, or Markdown
  • Link conversations to prompts as system instructions
  • Track token usage and cost per message
  • Full MCP support for chat via AI assistants

Multi-Model Testing

Test any prompt against 300+ AI models through OpenRouter. Stream responses in real time, compare results, and track token usage. Bring your own API key — Promptmark never touches your AI spend.

  • 300+ models from OpenAI, Anthropic, Google, Meta, and more
  • Side-by-side response comparison
  • Streaming results with real-time output
  • Token count and cost tracking per request
  • BYOK — your API key, your billing

Version Control and Backups

Every edit creates an automatic snapshot. View the full history of any prompt, compare versions with a diff view, and restore any previous state. Schedule remote backups to GitHub, S3, or Dropbox.

  • Automatic snapshots on every save
  • Side-by-side diff comparison between versions
  • One-click restore to any previous version
  • Scheduled remote backups (GitHub, S3, Dropbox)
  • Full export and import for portability

Private and Secure by Default

Your data lives in its own isolated SQLite database — not a shared table in a multi-tenant system. Safety scanning checks for PII, injection, secrets, and moderation issues before you publish.

  • Per-user database isolation
  • 4-layer safety scanning: PII, injection, secrets, moderation
  • Private by default — you choose what to share
  • AES-GCM encryption for sensitive credentials

Share and Collaborate

Publish prompts to your public profile. Share via direct links, QR codes, or oEmbed. Others can remix your work while preserving attribution.

  • Public profiles at promptmark.ai/u/yourname
  • Share links with automatic OG image previews
  • QR code generation for offline sharing
  • oEmbed support for embedding in blogs and docs
  • Remix and fork with full attribution

MCP and API Integration

Promptmark is MCP-native. Connect any MCP-compatible AI client and manage your entire prompt library through conversation. 38 MCP tools with OAuth 2.0 authentication.

  • 38 MCP tools for full prompt library management
  • Works with Claude Desktop, Cursor, Windsurf, VS Code, Zed
  • OAuth 2.0 with device flow support
  • REST API with JWT authentication
