WHY USERS LOVE PROMPT STASH

10x Faster AI Workflows
Type :: to instantly search and insert any saved prompt. No more switching tabs or digging through notes apps. One keystroke, done.

Smart Templates with Variables
Add {{variables}} to make any prompt reusable. Example: "Review this {{language}} code for {{issue}}" adapts to any language or concern. Chain modifiers like {{text | trim | uppercase}} for formatting, URL encoding, and JSON escaping.

Your Data Stays Private
Everything stored locally in Firefox by default. No accounts, no servers, no data collection. Optional Google Drive sync uses your own private appDataFolder. You control your data.

WHAT MAKES PROMPT STASH DIFFERENT

Most prompt tools require creating an account, subscribing to a plan, or trusting a third-party cloud with your data. Prompt Stash requires none of that. Your prompts live locally in your browser by default, and if you want to sync across devices, it uses your own Google Drive — not our servers.

That sync works across Firefox, Chrome, Edge, and Brave, so your prompt library follows you regardless of which browser you use. No other prompt manager offers true cross-browser sync without requiring an account on their platform.

Prompt Stash also works directly inside your AI chats. Save a prompt, add variables and modifiers, and reuse it without ever leaving the page. Template modifiers let you transform values with pipe syntax: {{variable | modifier}}. Available modifiers include uppercase, lowercase, trim, percent-encode, and json-stringify. Chain multiple modifiers for complex transformations.

Dynamic placeholders like {{UUID}}, {{TIME}}, and {{clipboard}} insert live values automatically. Visual badges show placeholder and variable counts so you always know what a template expects.

POWER USER TIPS

• Click "+ Create New Prompt" in the search overlay to save on the fly
• Right-click any text on any webpage to save it as a template
• Use descriptive variable names like {{programming_language}} instead of {{lang}}
• Tag your prompts for instant filtering and organization
• Export regularly to back up your growing prompt library
