What is PromptLib
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:
- Keep a reusable style, lighting, and camera vocabulary instead of rewriting it every generation.
- Templates with fill-in variables let you swap the subject while the look stays locked.
- Version history shows how a prompt evolved, so you can go back to the revision that worked.
- Workflows chain ordered steps for repeatable sequences — concept, prompt, variation, upscale brief.
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.

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.
