Trust model
Tikgu shows the evidence behind every recommendation.
The app is designed to state uncertainty instead of hiding it. Sources, freshness, and confidence are part of the product experience.
Grounded, not guessed
The recommendation pipeline requires product sources, price sources, purchase links, images, and review evidence.
Purchase links must be real
Marketplace search pages and merchant pages are allowed only when they are explicit purchase paths.
Weak evidence is rejected
Candidates without a source, price, image, or purchasable URL do not make the final top three.
Location is optional
Precise location is used only for nearby stores. Denial falls back to broad regions or online-only results.
Gemini only means no silent AI fallback.
The architecture uses Gemini for reasoning and grounded analysis. If Gemini credentials are missing, Tikgu shows setup status instead of pretending live data was checked.
