Name the source and target
The language/framework pair anchors the whole prompt so the AI knows exactly what it's converting to, not just 'modernise this'.

How it works
List your actual conventions
Naming, error handling, and structural rules you enter are assembled into explicit instructions instead of relying on the AI's default style.
Get an assembled, scored prompt
Fidelity level, test handling, and code size all shape the generated wording, and completeness is scored so you know if it's specific enough before you paste it.

Frequently asked questions
Does this tool convert my code itself?
No — it builds the prompt you paste into an AI coding tool alongside your actual source code. The conversion happens in that tool, not here.
Why does listing conventions matter so much?
Without explicit rules, an AI coding tool defaults to its own idea of 'idiomatic' target-language style, which often doesn't match your project's existing conventions — the generated prompt makes your rules non-negotiable instructions instead.
What does 'behavioral fidelity' control?
It tells the AI how strictly to preserve exact behavior versus producing a natural rewrite. High fidelity is safer for business logic; lower fidelity is fine for boilerplate or throwaway scripts.
Should I convert a whole file at once?
For anything over a few hundred lines, the generated prompt recommends chunking by module and reviewing each piece — large one-shot conversions are harder to verify and more likely to silently drop edge cases.
Will this port my tests too?
Only if you ask it to. You can choose code-only, porting existing tests, or having new tests written for code that doesn't have any yet.
How We Compare
| Feature | MVPHub | GitHub Copilot | Cursor |
|---|---|---|---|
| Assembles explicit convention rules into the prompt | Included | Not included | Not included |
| Scores prompt completeness before you use it | Included | Not included | Not included |
| Tool-agnostic prompt you can paste anywhere | Included | Not included | Not included |
| Free, no account required | Included | Not included | Not included |
GitHub Copilot and Cursor can both convert code inline when asked, but neither structures the request for you — you're writing the instructions from scratch each time. MVPHub builds and scores that instruction set first, so whichever tool you paste it into gets a consistent, convention-aware brief.
