Your prompt library, finally organized

Your best prompts, ready in one click with variables built in.

PromptKit is a lightweight Chrome extension for saving prompts, turning them into reusable templates, and swapping details using variable sets. Import/export makes your library portable and shareable.

A simple workflow that scales

Start with a prompt. Convert it into a template. Save variable sets. Reuse the same prompt across different projects without rewriting.

1

Save a prompt

Capture your best instructions once.

2

Add variables

Swap details without changing the structure.

3

Import variable sets

Switch contexts fast: clients, products, campaigns.

Templates that stay consistent

When your prompt library grows, consistency matters. Variables let you keep the “shape” of prompts the same while updating the inputs.

Example

Create a {{asset_type}} for {{audience}}. Voice: {{tone}}. Goal: {{goal}}. Constraints: {{constraints}}.

No complicated setup, just clean templates and reusable inputs.

Import & export in seconds

Move your prompt library between machines, back it up, or share a set with a teammate. PromptKit exports clean JSON files so your prompts and contexts stay portable.

Export prompts to a single file (promptkit-prompts.json).

Export contexts separately (contexts.json) to reuse variable sets across projects.

Import anytime to restore, migrate, or share a “starter library.”

Tip: Prompts and contexts are exported as plain JSON so you can version them, share them, or keep a simple backup.

promptkit-prompts.json

export

[
      {
        "id": "id_k3x9p1m0l8v2k9q9m2",
        "name": "Launch Email",
        "body": "Write a {{tone}} launch email for {{product}}. Audience: {{audience}}. Keep it {{length}}. CTA: {{cta}}.",
        "category": "Marketing"
      },
      {
        "id": "id_f1a7d2n4p0z8r3t6b1",
        "name": "Bug Triage Summary",
        "body": "Summarize tickets for {{sprint}}. Include: {{themes}}, {{risk}}, {{next_steps}}."
      }
    ]

Your export is a simple array of prompts — easy to back up, move, and share.

Your prompts, not someone else’s library

Why PromptKit?
Because prompts are assets, not content to scroll past.

They deserve better than being buried in tools that weren’t designed for real, repeatable work.

PromptKit keeps your best prompts ready, nothing more, nothing less.

What PromptKit does well

Save & organize your own prompts in a clean, distraction-free interface
Reusable variables so one prompt works for many situations
One-click copy with variables applied automatically
Import & export prompts and variables
Simple categories, no complex systems to maintain
Fast, local-first UX designed for daily use

What PromptKit avoids on purpose

Thousands of generic prompts you’ll never use
Feeds, dashboards, or “AI news”
Cloud accounts or subscriptions
“All-in-one” tools that slow you down
A learning curve just to save text

Local-first by design, your prompts stay on your machine unless you export and share them.
