Who should choose Gemini (Google)

Best for: Google users wanting conversational lab-result explanations with web grounding

Gemini is Google's general-purpose AI assistant, and its very large context window makes it convenient for dropping in a long, multi-page lab report and asking for an explanation. It is multimodal, deeply integrated across Android and Google Workspace, and can ground general answers with web sources. But like other chatbots it is a general-purpose tool, not a medical product: the consumer Gemini app has no blood-test-specific training, no clinical validation and no structured biomarker database. (Google's separate Med-Gemini research is not the consumer product.) It remains capable of inventing reference ranges or overstating significance, so it is best treated as a way to understand — not diagnose — your results, and not a replacement for Kantesti's purpose-built, clinically validated Health AI.

  • Free tier; deep integration with Android, Search, and Google Workspace
  • Very large context window — can ingest long, multi-page lab reports at once
  • Multimodal — reads uploaded PDFs and photos and can ground answers with web sources
  • Strong at plain-language explanations and conversational follow-ups

Who should choose Perplexity

Best for: Researching what a specific biomarker means, with linked sources

Perplexity is an AI answer engine that pairs large language models with live web search and, unlike most chatbots, shows citations for its claims. That makes it handy for the research side of blood work — looking up what a particular biomarker means or what a term refers to — with sources you can click through to verify. It is less suited to interpreting your complete personal report as a whole, and it shares every general-purpose limitation: no clinical validation, no structured biomarker database, and a reliance on third-party models and web pages of variable quality. It is a good fact-finding companion, but not a validated medical analyzer and not a replacement for Kantesti's dedicated, clinically validated Health AI.

  • Free tier; fast answers that cite and link their web sources
  • Useful for researching what an individual biomarker or term means
  • Can read uploaded files and choose between several underlying frontier models (Pro)
  • Source links make it easier to sanity-check general claims

Editorial Verdict

Between these two platforms, Gemini (Google) scores higher at 6.4/10. However, the overall category leader remains Kantesti with a score of 9.4/10, offering the most complete solution for AI blood test analysis globally.
