Our storyBuilt by a teacher who got tired of boring review games.
Hours spent writing questions for every lesson. Then the “game” was a quiz with a countdown timer glued on. Our students deserved real games — with characters, worlds, and stakes that make them forget they’re learning. So we built a tool that handles the questions and the game.
Around the world
Made for one classroom. Now in classrooms around the world.

Including United States, South Korea, Vietnam, Indonesia, Mexico, Spain and 36 more.
“Tembii has made my class warmup activities go from ‘meh’ to something the students are super excited about. You can generate question sets on any topic you can think of in literally about 2 minutes. Absolutely worth it.”

32 themed worlds
Real games. Not quiz wrappers.
Each world reshapes your questions into a different kind of play — competition, exploration, discovery, chance, and now puzzles you solve as a class. Use whichever fits the moment.

How it works
STEP 02
Tembii brews questions
AI reads your material and drafts vocabulary, grammar, and comprehension questions matched to your students' level.
STEP 03
You approve every one
Edit, swap, or reject. Nothing reaches your students until you give it the green check.
STEP 04
Pick a world and play
32 themed worlds. No student logins or accounts — run it from your laptop, tablet, or projector, and your class plays together on your screen.

Not just any AI
AI that writes questions like a teacher would.
Most AI quiz tools spit out basic multiple choice and call it a day. Tembii generates real assessments — graded, categorized, and aligned to how you actually teach.
CEFR-aligned for ESL & language learners
Every question is mapped to CEFR (A1–C2) — the internationally recognized standard for language proficiency — so you always know exactly where your students stand.
7 question types
Multiple choice, true/false, matching, fill-in-the-blank, ordering, open-ended, and picture choice.
Difficulty grading
Every question is tagged beginner, intermediate, or advanced — matched to your students.
Category tagging
Vocabulary, grammar, comprehension, cultural awareness — organized automatically.
The approval gate
Nothing reaches your students without you.
Tembii drafts. You decide. Edit any question, swap an answer, reject what doesn’t fit. The AI never bypasses you — it’s the only way we ship to a classroom.
- Every question shows up in your review queue first.
- Edit phrasing, change answers, or regenerate any item.
- Reject sensitive topics with one tap — Tembii won't reuse them.
- Save approved sets to reuse across classes and semesters.

Questions & answers
Is Tembii free?
Yes. The free plan includes 5 game worlds, 3 AI question sets a month, unlimited manual question-set creation, and full control to edit and approve every question. Premium includes all 32 worlds and up to 300 AI generations a month for $9/month, or $7/month billed annually ($84/year).
What ages does Tembii work for?
We design for ages 6 through 16. Games are tuned for 1-on-1 tutoring and projector classroom play.
What subjects can I use it for?
Any subject. Paste your lesson material — ESL, math, science, history, and more — and the AI builds questions from it. Games and questions are presented in English.
Can I edit the AI-generated questions?
Yes. Every question is yours to approve, edit, or reject before it reaches a student. Nothing auto-publishes.
Do my students need accounts or logins?
No. Tembii is teacher-driven — you run the game and students play along on the shared screen. Only teachers sign in, and students never enter any personal information.
Is my lesson data shared with anyone?
No. Your lesson text is sent to our AI provider only for question generation and is not used to train their models. We do not sell or share your content.
Do I need a webcam or special hardware?
No. Tembii runs in any modern browser on any laptop or tablet. Share your screen for classroom mode.
How does the free Premium trial work?
You get 14 days of Premium with no card needed. On day 14 it ends unless you add a card to keep it. Any question banks you saved stay yours either way.
How do I cancel?
From your account settings, any time. Your access continues until the end of the current billing period.
Your next lesson could be a barn dance.
Paste a lesson, approve the questions, and play before the bell.
