How it works
We calculate a portability score
Each structural element is weighted by how tool-specific it tends to be, then deducted from a fully-portable baseline to produce a 0-100 score.
Get rework guidance
The recommended next steps match your score, from porting directly to budgeting for significant manual rework.

Frequently asked questions
Does this tool read or convert my actual prompt text?
No. This is a calculator — it scores portability purely from the structural elements you tell it your prompts use. It does not read, convert, or transform your actual prompt text.
Why are tool/function definitions the least portable?
Custom tool/function definitions are usually bound to a specific tool's API or configuration format, so they typically require the most manual rework to reproduce elsewhere. Tool-specific context files carry a similar penalty for the same reason.
Why do system instructions score as more portable?
Plain system instructions or persona text are usually just natural language, so they tend to carry over with only light editing between tools.
Does the number of prompts change the score?
No, the score reflects the structural elements you flagged, not the volume. The prompt count is shown alongside your result so you can gauge total rework effort, not to change the score itself.
Is this a guarantee my prompts will work unchanged?
No. It's a directional estimate to help you plan rework time. Always test ported prompts in the target tool before relying on them.
How We Compare
| Feature | MVPHub | Manual prompt audit | Tool-specific migration guides |
|---|---|---|---|
| Instant portability score from your inputs | Included | Not included | Not included |
| Flags which specific elements need rework | Included | Limited | Limited |
| Reads or transforms your actual prompt text | Not included | Limited | Not included |
| Tool-specific setup instructions | Not included | Not included | Included |
A manual prompt audit can catch details specific to your prompts but takes time to do thoroughly. Tool-specific migration guides explain how to set up a target tool but don't score your existing prompts' portability. MVPHub gives a fast, transparent estimate to help you plan rework before you start.
