Effortless Workflow
How does it work in 3 steps?
Drop Your Rules or Repo
Drag your .cursorrules, CLAUDE.md, or whole project folder directly into the RAM studio.
AST Transpile & Sanitize
Our deterministic engine rewrites the exact syntax for your target IDE and automatically redacts leaked API tokens in memory.

The Cost of Inaction
Why you can no longer do this manually
- ✕45 minutes wasted manually reformatting YAML frontmatter and Markdown syntax.
- ✕Your AI ignores instructions because Claude Code silently drops Cursor-specific tags.
- ✕Catastrophic secret leak risk: active OPENAI_API_KEY committed to public GitHub repos.
- ✕Team desynchronization: every developer codes with divergent, outdated local instructions.
- 2 seconds flat: a 1-click drag-and-drop or single instantaneous terminal command.
- 98.5% verified AST fidelity: your coding agents strictly adhere to 100% of directives.
- Automatic in-RAM secret sanitization: leaked credentials masked with zero server traces.
- Universal 4-in-1 pack generated: Cursor, Claude, Windsurf & OpenAI aligned for $1.99.
Engineered For Reliability
The 4 pillars that set PromptShift apart
1. Radical Simplicity (Zero Learning Curve)
No need to be a compiler engineer. Drop your config and get instant, deterministic results in browser RAM or via CLI.
2. Complete Universality (All AI IDEs Supported)
Never get locked into a single AI environment again. Code in Cursor in the morning, run Claude Code in your terminal, and share with your team in Windsurf.
3. Sovereign Privacy (Zero Server Retention)
Your source code and prompts are never stored on any persistent database. All AST parsing executes ephemerally in RAM and purges instantly.
4. Transparent Micro-Pricing ($1.99 Single Pass)
No sneaky $39/mo subscriptions. Buy an impulsive $1.99 Single Pass strictly when you need to export a multi-rule repository.
Honest Pricing
Simple, predictable USD rates
