Steps
Once connected (see setup above), use the Dupe Finder tool:
- Describe the beauty or skincare product you want a dupe for — brand, product type, key ingredients, and what you use it for.
- Ask Claude to use `dupe-finder` with `find_dupe` to search for alternatives.
- Ask Claude to explain which alternatives match on the ingredients or properties that matter most.
- Ask whether any of the alternatives are genuinely equivalent or just superficially similar.
Example Prompt
Try this with Claude using the Dupe Finder tool
Use dupe-finder to find cheaper alternatives to The Ordinary's Buffet peptide serum (£15). I want something with similar peptide complex concentration for anti-aging. Find alternatives under £10 and tell me which ones are genuinely ingredient-equivalent versus ones that just sound similar.
Tips
- Specify the key active ingredients you care about so the dupe search focuses on formulation match, not just product category.
- Ask Claude to flag dupes that match the marketing language but differ significantly in active ingredient concentration.
- Check whether the texture and application method matter for your use case — a dupe with different consistency may not work the same way.
