About

PROMPTMATE — YOUR INTELLIGENT PROMPT VAULT

Stop losing your best AI prompts to the void.

PromptMate is a Chrome side-panel extension that saves, organizes, ranks, and dynamically assembles your prompts — surfacing exactly the right one for whatever you're doing right now. No more copy-pasting from Notion. No more hunting through chat history. Your prompts work with you, not against you.

Built for power users who live inside ChatGPT, Claude, Gemini, and Perplexity. Zero API keys required. Zero cloud sync. Your prompts stay local, private, and instant.

⚡ CORE FEATURES

▸ VAULT — Save Any Prompt in One Click
Highlight text in any AI chat window, right-click, and select "Save to PromptMate." That's it. Your prompt is stored, auto-categorized, and ready to deploy — across any session, any tab, any model.

Each saved prompt is automatically:
• Tagged by AI platform (ChatGPT, Claude, Gemini, Perplexity)
• Categorized by use-case (coding, writing, research, marketing, product, business, and more)
• Scored for quality using a multi-signal heuristic (role definition, output format, constraints, structure, examples, chain-of-thought)
• Tiered: Standard or Elite — your best prompts rise to the top

▸ ORACLE — AI That Reads the Room
Open the Oracle tab and PromptMate analyzes the content of your current page using BM25 — the same statistical ranking algorithm powering Elasticsearch — to surface the vault prompts most relevant to what you're working on right now.

No API calls. No internet connection. Pure offline intelligence.

Oracle surfaces:
• "Best Match for This Page" — the single highest-relevance prompt from your vault
• "Mix for This Page" — 4–8 ranked prompt chips you tap to blend into a compound prompt

▸ BUILDER — Compose Prompts Like a Maestro
Select multiple vault prompts and PromptMate intelligently blends them into one cohesive mega-prompt:
• First role/persona wins
• Bodies are numbered and structured
• Format signals are unioned and de-duplicated
• Specifics tail the blend

The result: a compound prompt capturing the intent of multiple prompts — without the redundancy.

▸ DEEP RESEARCH — Stay in Flow, Go Deep
One-click Deep Research launches a structured research prompt directly into your current AI chat window. No new tab. No lost context. Maximum momentum.
