About AI Tool Trivia

What is AI Tool Trivia?

AI Tool Trivia is a daily, browser-based quiz about the AI tools industry. Every day at midnight UTC, a new set of five questions is generated automatically from the Elofyn AI Tool Radar— a live tracker covering vendors, pricing, features, and categories for over 30 widely-used AI tools.

The questions test real industry knowledge: who makes which tool, what they charge for specific pricing tiers, which features are included in which plans, and how tools are categorised. There is no account, no install, and no ads. Your score is stored only in your browser's local storage.

Question types

Each session contains exactly five questions, one drawn from each of the following pools:

Maker (slot 1)vendor-id

Asks "Which company makes X?" The answer is the vendor name. Distractors are other vendors tracked in the Radar.

Pricing (slot 2)price-point

Asks "What is the monthly price of X's Y plan?" The answer is a formatted dollar amount. Distractors are real prices from other tools.

Features (slot 3)feature-spot

Asks "Which of these is a feature of X on the Y plan?" The correct answer is a real feature string. Distractors are features from other tools on the same-named tier.

Category (slot 4)category-id

Asks "What category does X fall into?" The six categories are: Coding & Development, LLM APIs, Image Generation, Video Generation, Productivity, and Agent Frameworks.

Maker reversal (slot 5)maker-reverse

Asks "Which AI tool is made by Y?" The answer is the tool name. Only vendors who make exactly one tracked tool appear here, preventing ambiguous answers.

Scoring

Each question has a 10-second countdown. Your score per question depends on whether you answered correctly and how much time was left on the clock:

perQuestionScore(correct, timeRemaining) =
  correct ? 100 + timeRemaining * 10 : 0

Examples:
  Correct with 10s left  →  200 pts (max)
  Correct with 5s left   →  150 pts
  Correct with 0s left   →  100 pts (minimum)
  Wrong or timeout        →    0 pts

Maximum score across five questions is 5 × 200 = 1 000. There is no partial credit and no penalty for guessing — it is always better to answer than to let the timer run out, since answering wrong with 8s left scores 0, while a correct guess scores at least 80 bonus points on top of the base 100.

Daily seed & fairness

Every player who opens the quiz on the same UTC calendar day receives exactly the same five questions in the same order, with the same answer options in the same positions. This is guaranteed by a deterministic question-selection algorithm.

The algorithm uses the djb2 hash function (Dan Bernstein, 1991) applied to the ISO date string YYYY-MM-DD. The hash output selects which question to draw from each of five typed pools (one pool per question type). A second djb2 pass picks three distractors without replacement from each pool's candidate list. A third pass shuffles the four options using a seeded Fisher-Yates shuffle.

Because the full computation runs on the server (Next.js React Server Component) and the results are sent as serialised props, there is no way to inspect tomorrow's questions from the browser — the server picks them fresh on each request using the current UTC date.

Data source

Questions are generated from radar.sqlite, the same database that powers the Elofyn AI Tool Radar. The Radar tracks pricing tiers, feature lists, and vendor metadata for over 30 major AI tools and is updated when vendors announce changes.

The pricing quiz pool filters to monthly plans with a published price between $1 and $999 (no custom-quote enterprise plans, no free tiers). The feature quiz pool filters to common tier names — Free, Pro, Teams, Enterprise, and so on — to avoid model-version–named tiers that would be confusing as quiz options. The maker-reversal pool excludes vendors with more than one tracked tool to prevent questions with genuinely multiple correct answers.

Sharing results

After completing the quiz you can copy a share card to your clipboard. The format uses three emoji to show per-question performance at a glance:

🟢Correct answer with 5 or more seconds remaining

🟡Correct answer with fewer than 5 seconds remaining

❌Wrong answer or timer expired

Privacy

AI Tool Trivia stores only one thing in your browser: the last 90 days of play records (date, score, and per-question correct/wrong flags) in localStorage. This is used solely to show your percentile relative to past sessions. No data is sent to any server. Clearing browser storage removes it entirely.
