Mentium · Features

What makes Mentium different from "another trivia app".

Three pillars: an AI that remembers how you play, an F2P-viable economy that respects your time, and real cultural anchoring across 8 languages.

A · AI with memory

Real personalization, not just randomness.

Mentium runs three layers of personalized AI. They work quietly, without intrusive popups, and you feel them after a few games.

Persistent rival

Pick one of 5 personalities (Taunter, Sage, Underdog, Friendly, Calculator). Their memory updates after every match — Classic, AI Category, AI Battle, Debate, Nexus, Detective, Traveler, Daily — and shows up in pre-game lines and post-game reactions.

  • Taunter Taunter
  • Sage Sage
  • Underdog Underdog
  • Friendly Friendly
  • Calculator Calculator

Daily coach

One motivational message per day, generated by Gemini, with adaptive tone: it picks up on days off, current streak, ignored streak, weak subtopics and recent topics. Ends with an optional CTA (Smart Review, Daily Challenge, Lightning, Nexus, a specific category) — or no CTA when the moment doesn't call for one.

Smart Review

Free adaptive review: 10 questions focused on the subtopics you miss most, kept in an internal buffer. Each correct answer drops the counter until the "You no longer fail at X" banner appears. Only surfaces with ≥3 weak subtopics — never as noise.

B · Economy

F2P-viable, no mandatory paywall, no pay-to-win.

Three resources, distinct roles. Purchases exist, but "Remove Ads" is reachable in 25–40 days of play, and the only non-consumable IAP (Rival Pack, €1.99) is purely cosmetic.

  • Coins

    Soft, infinite. Earned by playing, spent on premium modes and lifelines.

  • Mentis

    Premium. Earned via achievements, missions, chests, rewarded ads (1/day) or IAP. Never required.

  • Lives

    Cap 0–10. Regen 30 min/life up to 5. Above 5: ads, IAP, chests or won matches.

XP follows an exponential curve; daily streak multiplies XP from ×1.0 to ×2.0.

75 achievements (Bronze/Silver/Gold/Platinum) totalling 1,360 coins + 713 Mentis, plus 10 exclusive secret avatars.

5 chest tiers with difficulty-scaled drop tables; daily chest auto-roll with published probabilities.

C · 8 languages with cultural anchoring

The Turkish Daily Challenge isn't about generic Olympics.

Each locale has a calibrated LOCALE_FOCUS. Daily generation at 03:00 UTC produces a set of 10 questions anchored to the player's country (or region).
