Your prompt library, finally organized

Keep your best prompts ready in one click with variables and packs.

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.

Pick a context, then copy a prompt with variables filled in automatically.

Built for reusable prompts

Keep your best prompts close and keep them flexible when the details change.

Template variables

Turn static prompts into templates with placeholders like {{tone}}, {{audience}}, and {{constraints}}.

Generate a {{format}} plan for {{project}} with {{constraints}}.

Import / export prompts

Move prompts between machines (or share a prompt pack). Keep your library portable and backed up.

Export a full collection
Import a shared pack
Keep formats consistent

Variable imports

Load variable sets for a project, client, or campaign — then reuse the same templates instantly.

{ "client": "Acme", "tone": "direct", "length": "brief" }

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.
