Your API keys,
on your device only.
OpenAI, Claude, Cursor — all your API keys stay encrypted and local. Your tools work as usual, your keys never leave.
Works with all major AI providers
Why dedicated API key management?
Password managers handle logins. ProphetKey handles API keys — the right tool for the right job.
Local Encrypted Storage
Each key is individually encrypted with XChaCha20 and stored locally. Even if the database file is stolen, all they get is garbled data.
Local Proxy Access
Your AI tools read keys directly from the local proxy. Keys never leave your machine, no more copy-pasting.
Key Health Audit
Automatically checks encryption strength, expiry risk, and unusual usage patterns. Proactive alerts, not reactive panic.
Shadow Keys + TOTP 2FA
Assign virtual keys to each tool, real keys never exposed. Sensitive operations need TOTP verification.
Leak Monitoring
Automatically scan public code repositories for leaked keys. Get notified the moment something suspicious is detected.
Time Window Control
Restrict proxy requests to configured hours. Outside the window, the proxy blocks traffic automatically.
Cost Manager
Track API usage costs across all your AI providers. Set budget alerts and see which tools consume the most credits.
Proxy Token Refresh
Regenerate the local proxy mapping so compromised virtual keys stop working. Your real provider API key stays unchanged.
Encrypted Cloud Sync
Sync encrypted key vaults across your devices. Data is encrypted before leaving your machine — we never hold the keys.
30 seconds to set up, zero learning curve
No code changes, no config changes, no restarts. Just works.
Store It
Put your OpenAI, Claude, Cursor API keys into the local vault. Done in 30 seconds.
Auto-Manage
The system generates virtual keys for each tool. Real keys stay locked in your machine.
Use Directly
Your tools work as usual, you won't notice a difference. But your keys are now secure.

FAQ
What is ProphetKey?
An API key manager for your AI tools. OpenAI, Claude, Cursor — store keys once, tools read from a local proxy. No more copy-pasting, keys never leave your machine.
What happens if my API keys leak?
GitGuardian's State of Secrets Sprawl 2026 report logged 28.6M+ secrets leaked on public GitHub in 2025 — a 34% jump year-over-year, with AI-service key leaks up 81%. 70% of secrets leaked in 2022 were still active two years later. Leaked keys get used to drain credits, send spam, and steal data. This is not a small risk.
How does ProphetKey keep my keys safe?
All keys are encrypted locally with XChaCha20-Poly1305 + Argon2id. Only encrypted blobs ever touch the cloud. Your plaintext keys never leave your device.
Which AI tools does ProphetKey support?
OpenAI, Claude, Cursor, Copilot, Midjourney, Stability AI — all major providers. More being added.
What can I do with the Free plan?
5 keys, local proxy, shadow keys. Enough for personal use.
Is ProphetKey's encryption technology safe?
XChaCha20-Poly1305 encryption + Argon2id key derivation + device fingerprint binding. Zero-trust architecture — even a database breach can't decrypt your keys.
What's the difference between Sentinel, Guardian, and Prophet?
Sentinel is for power users — 20 keys + health audit + TOTP 2FA + time window control. Guardian adds leak monitoring, cost manager, and cloud sync. Prophet is for heavy use — unlimited keys + dedicated support.
How do I migrate from 1Password or Bitwarden?
Import directly from .env, JSON, 1Password, and Bitwarden CSV exports. The import wizard auto-detects your file format.
Does ProphetKey support macOS and Linux?
Phase 1 supports Windows 10+. macOS and Linux are on the roadmap, expected Q4 2026.
Does the Free plan expire?
No. Free plan is permanent, 5-key quota is never reclaimed.
