Which AI?
Quiz site that tells you which AI to use and which plan to get





Overview
A small quiz site that tells you which AI to use and which plan to get. It asks five questions: what you mainly use AI for (studying, coding, professional work, or everyday help), the task that matters most, your monthly budget, whether open source matters (open weights, or running it on your own device), and how you need to access it (a simple app, technical access like API keys and coding tools, or confidential for client or company data). A bonus question asks how much you'll use it when that changes the plan, and picking "run it on my device" asks about your device and RAM instead.
The result names one AI: Gemini, Claude, ChatGPT, or DeepSeek, or Qwen to run locally. It explains why it fits, names the exact plan to get within your budget, suggests an alternative to test, and lists sourced pros and cons.
Features
- One straight answer: a pick for your task, not a benchmark chart or a ranking.
- The plan, not just the model. It picks the cheapest option that works and sizes it to how much you'll use it, like Google AI Plus for studying or OpenCode Go for coding on $10 a month.
- Never over budget. If nothing fits, it says "No match" instead of recommending something you can't afford.
- Prices, plans, and claims come from a dated research snapshot (Sept 28, 2026), and the site tells you to double-check before you buy.
- Local option: Qwen comes with a hardware check (device and RAM), a model size, and a setup path through Ollama or LM Studio.
- Shareable results: answers live in the URL, so a result can be sent to a friend.
- Public feedback board with ratings and notes from people after they got their match.
- No sponsorships and no paid picks.
Highlights
- The recommendation engine is one pure TypeScript function, tested across every answer combination with Node's built-in test runner.
- Feedback runs on Convex: a live board query and a submit mutation with validation and rate limits.
- A Next.js Server Action hashes the visitor's IP for a one-note-per-hour limit and passes a server-only secret to Convex.
- Notes with swearing or slurs are refused in English (obscenity package) and Filipino (sourced word lists).
- Each production deploy on Vercel also deploys the Convex functions.
- Notebook-doodle look in CSS Modules and plain CSS: ruled paper, hand-drawn shapes, and keyframe animations.
