Steps
Once connected (see setup above), use the Dupe Finder tool:
- Describe the premium beauty product and what result you are trying to replicate.
- Ask ChatGPT to use `dupe-finder` with `find_dupe` to find alternatives.
- Have ChatGPT produce a comparison showing key ingredients, price, and similarity rating for each alternative.
- Ask for a buying recommendation with a justification explaining why the chosen dupe is the closest match.
Example Prompt
Try this with ChatGPT using the Dupe Finder tool
Use dupe-finder to find cheaper alternatives to Charlotte Tilbury Flawless Filter (£39). I want a similar glow-enhancing base with light coverage. Find options under £12 and return a comparison with product name, price, key ingredients or properties, and a note on how close the finish is to the original. Recommend the best one.
Tips
- Ask for a note on finish and texture alongside ingredients — in makeup, the sensory result often matters more than the formulation.
- Include the price-per-use if the comparison involves different product sizes.
- A single strong recommendation with justification is more useful than a long list with no guidance.
