Grow your prompts — version history, result notes & chains for Claude, ChatGPT & Gemini. Your prompts never leave your device. Most prompt managers stop at "save and recall." PromptLab is built to grow your prompts. • One-click save & insert — drop a saved prompt straight into the AI site's input field • Works with Claude, ChatGPT & Gemini — installs with access to claude.ai only; enable ChatGPT / Gemini per site in settings (Chrome asks for your confirmation, revoke anytime) • Variable templating — write {name} and fill in values on insert (same name replaced everywhere) • Version history — every edit is kept as v1, v2…; roll back anytime without losing anything • Result notes — rate 👍/🤔 with a quick note to track which prompts actually work; see the good-rate • Prompt chains — bundle a fixed flow (e.g. "design → implementation brief") and run it one step at a time • Search, sort & backup — search title/body, sort by good-rate, export/import as JSON A lab notebook for prompts, not a bookshelf. Designed as a daily tool: minimal clicks, high information density. FREE & PRO The free plan includes 10 prompts, 2 history versions per prompt, and 1 chain — result notes are unlimited. PromptLab Pro removes all limits: $5/month or $50/year (license key, no account needed). If you downgrade, nothing is deleted — existing data stays readable and exportable. PRIVACY • Your prompts never leave your device (chrome.storage.local). The only thing ever sent is your Pro license key string, for verification — and only if you activate Pro. Free plan = zero network traffic. • Installs with claude.ai access only. ChatGPT / Gemini are per-site opt-in. It does not request <all_urls> (read data on all sites). • It calls no LLM and runs no analytics. • Payments are processed by Stripe; we never see your card details.
