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.
