Questions about real prompting decisions
Every question is a choice you make when you write a prompt: which instruction to give, where a prompt goes wrong, what to change to fix it.
Features
Everything you need to practice prompting.
TokIQ is deliberately simple: one question at a time, an explanation for every answer, and progress you can see. Here is everything in the app.

“Why?” explanations
After you answer, tap Why? for a short explanation of the idea behind the question, followed by three follow-up questions on the same point.
Eight prompt engineering topics
Fundamentals, role & context, examples, reasoning, structured output, grounding, tools & agents, and safety.
Three levels
Beginner, intermediate and experienced levels, so the quiz stays useful whether you are new to AI or ship LLM features for a living.
Tuned to how you use AI
Tell TokIQ which tools you use (ChatGPT, Claude, Gemini, Copilot, Perplexity) and what for: work, study, writing, research or code.
Progress per topic
See your accuracy topic by topic, so you know exactly which skills are still weak.
Global ranking
Compare your XP with other players on a global leaderboard, shown under a nickname you choose or a masked label.
Evening reminder
An optional reminder in the evening, so a couple of questions a day becomes a habit.
One question at a time
No timer and no fixed round length. Answer one question or twenty, and set a daily goal of 3, 5, 10 or 20 if you want one.
40 languages
The interface, questions and explanations are available in 40 languages, from English and Spanish to Azerbaijani, Japanese and Arabic.
Light and dark mode
A calm, low-glare design that is easy to read for longer sessions.

QuizProgressProfile
Structured outputIntermediate
Your app parses the model’s JSON, but sometimes the reply starts with “Sure! Here is the JSON:”. What is the most robust fix?
AAdd “please” to the prompt
✓Use structured-output mode with a schema, then validate
CLower the temperature to 0
DStrip the first line of every reply
That’s right! +10 XP
Structured-output modes constrain the reply to valid JSON. Validation catches the rest.
Why?Next
Why?
Why string hacks break JSON parsing
A model that adds a friendly sentence before its JSON is doing what chat models are trained to do. Telling it “no preamble” helps, but only a schema-constrained mode makes the shape a guarantee.
{ "title": string,
"priority": "low" | "high" }
"priority": "low" | "high" }
Validate every reply. When it fails, retry once and include the validation error.
