Why switch
PromptVault vs Easy Folders
Easy Folders works on two AI platforms and gives zero folders on its free tier. PromptVault covers four platforms (ChatGPT, Claude, Gemini, and Perplexity) and ships five free folders before you decide to upgrade.

Common questions
- Will PromptVault touch my AI conversations?
- No. The extension is read-only on every supported AI site. It reads the conversation list to apply folder labels but never modifies, deletes, or re-orders conversations.
- How does the AI auto-categorisation work?
- Pro auto-categorisation runs the conversation title through on-device browser AI to suggest a folder. You confirm or override; nothing is written until you confirm.
- What if I uninstall — do I lose my folders?
- Folder definitions live in chrome.storage on your device. Export to JSON before uninstalling to keep a portable copy. Re-importing on a new machine restores your folder tree exactly.
- How does the Aegis Pro Pack unlock PromptVault?
- Sign in to aegisfirma.com from any installed Aegis extension popup. The cookie-auth flow detects your active Pro Pack and unlocks Pro features instantly — no license key to copy or paste.
- Where is my PromptVault data stored?
- PromptVault stores everything in chrome.storage on your device. Your subscription record lives in our payment provider's account; we do not aggregate browsing or activity data.
- Can I cancel PromptVault Pro anytime?
- Yes — billing stops at the end of the current period. Pro features remain active until the period ends, then drop back to the free tier.
- Why should I trust an extension I just heard of?
- Aegis extensions never change ownership and never sell user data. We publish security audit results and ship MV3-native code so Chrome itself enforces the permissions we claim.
