Prompt manager for AI visual creators. Save, organize & instantly reuse image, video & chat prompts with variables & templates. PromptLib is a prompt manager for AI visual creators — a Chrome extension for saving, organizing, and reusing the prompts behind your images and videos, across the AI tools where you actually work.
When a prompt finally nails the lighting, the style, and the composition, that prompt is an asset. Instead of re-describing the same look from memory, digging back through old generations, or keeping prompt notes scattered across documents, PromptLib gives you a dedicated prompt library inside Chrome. Save prompts, templates, selected text, workflows, global variables, tags, and versions in one place, then bring them back the next time you need that exact result.
Built for the way visual work actually goes:
The library lives in Chrome rather than inside any one site, so it works alongside the browser-based AI tools you already use — your saved wording stays available wherever you type.
What PromptLib does:
Free, Premium, and Lifetime access:
The Free plan supports up to 10 active prompts/templates, 3 active local workflows, 3 active local Global Variables, one active device, local JSON export, and complimentary account backup for supported data when signed in.
Premium includes unlimited prompts/templates, workflows, and Global Variables; Quick Menu; clipboard and version history; import and restore; Premium Library access; realtime cross-device sync for supported prompts, templates, workflows, and Global Variables; and up to 3 active devices by default.
Lifetime access includes unlimited local prompts/templates, workflows, and Global Variables plus Quick Menu and local history on one active device. Realtime cross-device sync is a Premium subscription feature. Feature availability is also shown before upgrade or purchase.
Why install it:
PromptLib is built for AI visual creators — people generating images and video, art directing with AI, producing UGC and short-form content, or running any repeatable visual workflow across many websites. It keeps your best prompts close to where you type while giving you structure for longer-term prompt management. If you also work with text prompts for writing, research, or support workflows, the same library handles those too.
Install PromptLib if you want a cleaner, faster way to manage the prompts and reusable instructions you rely on every day.
