PromptKeeper

Save, organize, and optimize AI prompts. Sync via Google Drive. Local AI with Gemini Nano. Side Panel for easy paste-to-page.

PromptKeeper is your private, local AI prompt engineering workspace—right in your browser. WHAT'S NEW IN v2.1.1 • Streaming + Cancel AI: On supported Chrome builds, AI output can stream into the editor progressively. While running, buttons switch to "Cancel" so you can abort long operations. • Model Download Progress: If Gemini Nano is warming up/downloading, PromptKeeper shows a "Downloading..." indicator when Chrome provides progress events. • Local Model Stats: A compact "Local Model Stats" line shows token usage/quota (when available) under the editor. • Markdown Support: Prompts now display as rich text (Bold, Lists, Headers). Click the text to edit instantly. • Keyboard Shortcuts: Use Cmd+B and Cmd+I to format your prompts faster. • Editor Tuning: Shared font-size controls for editor and preview, resizable right-hand panel, and improved side panel / full-editor flow. • Safety & Autosave: Stronger AI prompting (no invented personas, clearer placeholders) plus optional auto-save and auto-save-on-switch so you don’t lose changes. • Side Panel View: Browse, edit, and paste prompts directly into Claude, Gemini, Perplexity, ChatGPT and other tabs without leaving the page. • Full‑screen Prompt Management: A view for deep work, with live word count, AI tools, and Google Drive controls in the sidebar. • Workspaces & Projects: Group prompts by topic (Work, Creative, Coding, etc.), drag‑and‑drop between projects, and use right‑click context menus for smart deletion. • Google Drive Sync: Backup and restore your entire library (prompts + workspaces) to your Google Drive. • Version History: Every save creates a new revision; quickly time‑travel across the latest 50 changes per prompt. • Optional On‑device Gemini Nano: Refine prompts locally without API keys (where supported). BUILT-IN AI OPTIMIZATION (Gemini Nano, on-device) Leverage Chrome's on-device AI (when available) to refine your prompts without sending data anywhere. • Magic Enhance: Turn rough notes into structured prompts instantly. • Formalize, Clarify, Shorten: One-click refinement tools to adjust tone and clarity. • Zero API Keys: Uses Chrome's local Gemini Nano model; when the model is available, everything runs on-device. AI tools live in the full-page PromptKeeper editor so you can iterate deeply on prompts without cluttering your chat window. GOOGLE DRIVE SYNC Your prompts, everywhere. • Automatic backup to a dedicated file in your Google Drive. • Cross-device access: Sign in on any computer. • We never see your data—it stays in YOUR Drive. WORKSPACES & PROJECTS Organize like a pro. • Create named workspaces for Work, Creative, Coding, etc. • Drag-and-drop prompts between projects. • Right-click context menus for quick actions. The side panel gives you quick access to this library while you’re in Gmail, Docs, or any other tab—so you can paste polished prompts into AI tools with one click.
