gryffins-brainlab · built by a kid, for his brain

23 subjects.
One brain lab.

Gryffin runs his own training arc — Math, ELA, History, Science, plus the stuff he actually cares about (DBZ, Pokémon, Minecraft) — with a fox named Kit answering questions, a Show-Your-Work pad for the hard ones, and a 4-game arcade for when the brain needs a break.

Arcade unlocks. Brain warmed up? Cash in some XP and go play.

Who it's for

One kid. His own training arc.

Not a homework app. A lab Gryffin opens on his own time, because the questions are about the stuff he actually wants to be good at.

Gryffin

Youngest Perina · Artist · Saiyan

Picks the subject. Answers the question. Shows his work when the problem needs it. Decides when to cash XP for arcade time and when to keep grinding.

"DBZ counts as a subject because I said so."

Lab lives at gryffins-brainlab.vercel.app. He named the subjects, picked DBZ as the universe, and decided XP was the only currency that mattered. We built it together one afternoon and haven't touched it since.

Kit

Fox · AI · Sparring partner

Reads the question out loud. Explains the wrong answer without making him feel small. Pulls a step-by-step breakdown when the math gets ugly — and switches into DBZ-lore mode the second the subject does.

Kit doesn't grade. Gryffin grades himself. Kit just keeps the pace going.

Six things that make it Gryffin's

Not a quiz app. A training arc.

Every one of these started as Gryffin asking for it out loud. He wanted boss fights, so we built boss fights. He wanted a Show Your Work pad because the math felt fake without one. The list is the chat log.

Voice — Ask Kit

Talk to the fox.

Tap Kit, ask the question out loud, hear the answer back. Pacing controlled by your mouth, not a textbox.

Ask Kit · text

Type it instead.

Same fox, same brain — just quieter. Drop a problem in, get a hint first. Ask for the full breakdown if you still need it.

Show Your Work

The scratch pad.

Hard problems get a write-it-out canvas. Kit reads your steps, calls out where the wheels came off, and lets you keep going.

Continuous quizzes

Never the same set twice.

Pick a subject and it just keeps generating. Get one right and the next one's harder. Get one wrong and Kit walks it back.

4-game arcade

Brain breaks, earned.

Cash XP from quizzes to play. Four games. None of them eat the whole afternoon — they reset you and send you back to the lab.

Saiyan subjects

DBZ + Pokémon are real subjects.

The lab respects what Gryffin's actually into. Dragon Ball lore quizzes count. Pokémon type-matchups count. School isn't the only brain workout.

By the numbers

The receipts.

Everything in the lab, counted up.

What a quiz looks like

One question. A hint. A fox.

Prompt, options, a Show-Your-Work button for the hard ones, and Ask Kit if the brain hits a wall. That's the whole screen.

brainlab Algebra Level 4 🔥 7-streak
Level 4 · AlgebraEarn 80 XP to level up

Question 8 of ∞ · Power Level 9,000+

If 3x + 7 = 22, what is x?

Show Your Work

3x + 7 = 22 → subtract 7 from both sides → 3x = 15 → divide by 3 → x = 5. Goku-approved.

The arcade

Earned brain breaks.

Four games. Stack XP from quizzes, cash it in, play a round, come back sharper.

Aim Drill

Quick-tap accuracy game. Reflex tune-up between sets.

Match Lab

Type-matchup puzzle, Pokémon-coded. Pattern recognition warmup.

Charge Up

Timing minigame. Hold to power, release on the beat. Pure focus.

Memory Saiyan

Card-flip memory grid. Longer sequences as you level. Brain dessert.

How the AI works

One question. One fox. Real explanations.

The same pipeline runs whether Gryffin asked by voice, typed it, or scribbled it on the work pad.

1 · Ask

Voice, text, or a scribble on the Show-Your-Work pad.

2 · The model

Subject context loads first (Algebra rules, DBZ canon — whatever the lane is). Then Kit answers in that voice.

3 · The breakdown

Hint first. Full step-by-step only when you ask. Pace stays Gryffin's.

The sibling site

And when the brain wants to fight.

Brain Lab's serious twin. Same kid, same fox, full DBZ mode.

Rollgame

The DBZ Arena

gryffins-rollgame.vercel.app

The other half of Gryffin's setup. DBZ-coded mini-games, coin economy with proper persistence, inventory, daily challenges, and a chat layer powered by the same fox. When Brain Lab's about reps, Rollgame's about points on the board.

Coins persist Inventory Daily challenges Kit chat Admin tools

What it doesn't do

The honest version.

What the lab doesn't try to be — Gryffin and I would rather name it than have someone find out later.

The lab doesn't replace school

It's reps and curiosity, not a curriculum. Teachers still pick the assignments. Brain Lab just makes the practice fun enough to do.

Voice needs a mic permission

First time you tap the fox to talk, the browser asks. Skip it and Ask Kit still works as text — just slower.

The arcade has a leash

XP doesn't unlock infinite play. The lab brings you back to a question after a round. By design.

Kit can be wrong

Fox is smart, not infallible. If the breakdown looks off, push back. Show Your Work pad is there exactly for that.

What ships next

The Gryffin punch list.

Each item is scoped, queued, and waiting on the prior one to clear.
