Hey HN! Indie dev from Japan here.

I built PromptStash because I kept retyping the same prompts across ChatGPT, Claude, Gemini, and other AI tools. It started simple, but evolved into something more powerful.

*What it does:* - Save prompts and insert them with one click (or slash command "/") - Works on 19+ AI services including ChatGPT, Claude, Gemini, Perplexity, DeepSeek, Grok - Variable templates: `{{language:select:English,Japanese}}` for dropdowns, `{{topic}}` for text input - Context variables: `{{selectedText}}` auto-captures highlighted text, `{{pageUrl}}` grabs current URL - Prompt chains: string multiple prompts together for multi-step workflows (e.g., "gather requirements" → "design" → "implement")

*Example use case:* I have a chain for code review: first prompt asks for potential bugs, second asks for performance improvements, third asks for refactoring suggestions. Click "next" after each AI response.

All data stays local in your browser. No account needed.

$5 one-time (free tier: 3 prompts). I'm trying to build sustainable software without ads or subscriptions.

Feedback welcome – especially on the prompt chain UX. What workflows would you automate?
