# About Kevin Liu

I am an infra-product engineer at [General Translation](https://generaltranslation.com) based in San Francisco.

I am 19, and I've been coding and designing since I was 12. I am currently attending [Princeton University](https://www.princeton.edu).

I design interfaces that feel alive, from first principles, with a spirit of their own. I follow friction toward what is missing, and treat environments as part of the product. I build strange observations into useful worlds through type, skills, and protocols.

This site shows 26 of the projects as collectible cards. Every number on a card has a receipt from the project's repository.

# Battle

Kevin Liu's card battle is a free browser game in which three of his project cards play three more. The engine is deterministic: the same teams and seed always play the same battle.

- Teams: 3 cards whose inks add up to 7 or less.
- Disciplines form a ring: Infra, Agent, Data, Game, Shader, Type, Interface. An attack is 1.5x against the next discipline on the ring and 0.67x against the previous one; every other pairing is 1x. Dual disciplines multiply.
- Two modes share one engine. Mat plays the battle on a card mat with a cutscene for every move. Arena plays it on a painted floor, with eight original trainer figures.
- The battle holds 18 cards today: [Turboslide](https://www.kevinliu.studio/cards/turboslide), [Glyphfield](https://www.kevinliu.studio/cards/glyphfield), [Jarhead](https://www.kevinliu.studio/cards/jarhead), [Katagami](https://www.kevinliu.studio/cards/katagami), [Claude of Tanks](https://www.kevinliu.studio/cards/claude-of-tanks), [Mailroom](https://www.kevinliu.studio/cards/mailroom), [Local Search](https://www.kevinliu.studio/cards/local-search), [Agent Pets](https://www.kevinliu.studio/cards/agent-pets), [Loop](https://www.kevinliu.studio/cards/loop), [Agent Machines](https://www.kevinliu.studio/cards/agent-machines), [Prototemplate](https://www.kevinliu.studio/cards/prototemplate), [bday.land](https://www.kevinliu.studio/cards/bday-land), [Princeton Powerlifting](https://www.kevinliu.studio/cards/powerlifting), [Elo](https://www.kevinliu.studio/cards/elo), [CoTFly](https://www.kevinliu.studio/cards/cotfly), [Relay](https://www.kevinliu.studio/cards/relay), [Princeton TD](https://www.kevinliu.studio/cards/princeton-td), [Kevin Wiki](https://www.kevinliu.studio/cards/kevin-wiki).

# Turboslide

Turboslide is a browser slides editor where people and AI agents edit one deck.

Card 1 of 26 in Kevin Liu's collection. 2026. Agent and Interface.

- Live: https://www.turboslide.com
- Source: https://github.com/Kevin-Liu-01/Turboslide
- Battle: https://www.kevinliu.studio/battle#team=turboslide,katagami,mailroom
- Inks: 4
- Health 337, attack 112, defence 129, speed 129

## The numbers

- **1,232 commits**. Receipt: `git rev-list --count 3e22c8f54`
- **5 GitHub stars**. Receipt: `gh api repos/Kevin-Liu-01/Turboslide --jq .stargazers_count (2026-10-30)`
- **768 check files**. Receipt: `gh api repos/Kevin-Liu-01/Turboslide/git/trees/3e22c8f54?recursive=1 | grep -cE <glob>`
- **33.3 commits per active day**. Receipt: `1232 commits over 37 distinct commit dates, 2026-09-10 to 2026-10-22`

## Trait

**Preloaded**. Turboslide loads each page before you click, so its first move after entering goes first. Receipt: `Turboslide@3e22c8f54:apps/studio/src/router.tsx:84; README.md:69 (168 ms from click to a settled studio)`

## Moves

- Live Pointers hits for 30 twice, 95% of the time. People and AI agents edit one deck at once, each with a named pointer; changes appear within a second. Receipt: `Turboslide@3e22c8f54:AGENTS.md:104-107; README.md:40; apps/studio/src/components/site/pages-copy.ts:254,704; apps/studio/home-deck/recorded-chips/chips.json:2`
- Perfect Export hits for 60. PowerPoint pages export as screenshots, checked against the screen before saving, so the file matches the editor. Receipt: `Turboslide@3e22c8f54:README.md:66; packages/theme/brand/facts.json:45-48`
- Two Tone hits for 50. Pictures print in two colors through an 8 by 8 dot pattern, and the editor and the export match pixel for pixel. Receipt: `Turboslide@3e22c8f54:README.md:65; docs/native.md:3-4, 16-22`
- Revision Check raises a 50% barrier. Every edit names the deck version it read. An edit made on an old version is refused, so nobody overwrites newer work. Receipt: `Turboslide@3e22c8f54:packages/agent/src/generate/manifest.ts:80; README.md:117; AGENTS.md:68-78, 100-103`

Card 2 of 26 in Kevin Liu's collection. 2026. Type and Shader.

- Live: https://www.glyphfield.com/studio
- Source: https://github.com/Kevin-Liu-01/Glyphfield
- Battle: https://www.kevinliu.studio/battle#team=glyphfield,katagami,mailroom
- Inks: 4
- Health 323, attack 126, defence 127, speed 120

## The numbers

- **409 commits**. Receipt: `git rev-list --count 0fb6cbd71`
- **19 GitHub stars**. Receipt: `gh api repos/Kevin-Liu-01/Glyphfield --jq .stargazers_count (2026-10-30)`
- **301 check files**. Receipt: `gh api repos/Kevin-Liu-01/Glyphfield/git/trees/0fb6cbd71?recursive=1 | grep -cE <glob>`
- **9.3 commits per active day**. Receipt: `409 commits over 44 distinct commit dates, 2026-07-22 to 2026-10-28`

## Trait

**Deterministic**. The same request always returns the same graphic, so its moves never miss. Receipt: `Glyphfield@0fb6cbd71:README.md:93`

## Moves

- Material Lab hits for 70, 95% of the time. Design Lab sets a brand’s logo over any of 197 live shaders, animated textures from the graphics card. Receipt: `Glyphfield@0fb6cbd71:README.md:41, 55-57; src/app/page.tsx:203-206`
- Motion Study hits for 55 and raises its Pace. The Animation tool turns the brand’s text, logo and images into timed scenes, exported as GIF or MP4. Receipt: `Glyphfield@0fb6cbd71:README.md:39`
- Source View raises a 40% barrier. Every tool opens its state as editable code, and an edit there updates the same visual controls. Receipt: `Glyphfield@0fb6cbd71:README.md:51`
- Agent API hits for 45 and goes first. AI agents make templates and backgrounds with one web request and get a vector graphic back, no browser needed. Receipt: `Glyphfield@0fb6cbd71:README.md:93`

# Jarhead

Jarhead is a voice assistant that clicks, types and reads the screen on your Mac.

Card 3 of 26 in Kevin Liu's collection. 2026. Agent and Interface.

- Live: https://jarhead.kevinliu.studio/
- Source: https://github.com/Kevin-Liu-01/Jarhead
- Battle: https://www.kevinliu.studio/battle#team=jarhead,katagami,mailroom
- Inks: 4
- Health 332, attack 128, defence 124, speed 127

## The numbers

- **708 commits**. Receipt: `git rev-list --count 50d54e83c`
- **30 GitHub stars**. Receipt: `gh api repos/Kevin-Liu-01/Jarhead --jq .stargazers_count (2026-10-30)`
- **226 check files**. Receipt: `gh api repos/Kevin-Liu-01/Jarhead/git/trees/50d54e83c?recursive=1 | grep -cE <glob>`
- **26.22 commits per active day**. Receipt: `708 commits over 27 distinct commit dates, 2026-08-10 to 2026-10-23`

## Trait

**Relaunch**. Jarhead relaunches after a crash, so the first hit that would end it leaves 1 Health. Receipt: `Jarhead@50d54e83c:README.md:86; README.md:396; apps/mac/Sources/Jarhead/Daemon/DaemonProcess.swift:245`

## Moves

- Wake Word raises a 40% barrier. Asleep, it listens on the Mac only for its name. Touch ID or a password must pass before it takes a command. Receipt: `Jarhead@50d54e83c:README.md:67, 406`
- Reflex hits for 35 and goes first. Clear commands such as “scroll” or “click Save” skip the AI model and run in about 8 ms. Receipt: `Jarhead@50d54e83c:README.md:71; README.md:365`
- Threads hits for 18, 1 to 4 times, 95% of the time. Up to three extra Jarheads split a request, each working at once with its own AI model. Receipt: `Jarhead@50d54e83c:README.md:72; README.md:392`
- Computer Use hits for 55. It takes a screenshot, finds a button by its label and clicks it, using 71 tools for the Mac. Receipt: `Jarhead@50d54e83c:README.md:70; README.md:397`

# Katagami

Katagami is a free font family in five styles for interfaces, long reading and code.

Card 4 of 26 in Kevin Liu's collection. 2026. Type and Interface.

- Live: https://katagami.kevinliu.studio/
- Source: https://github.com/Kevin-Liu-01/Katagami
- Battle: https://www.kevinliu.studio/battle#team=katagami,turboslide,mailroom
- Inks: 2
- Health 309, attack 103, defence 107, speed 113

## The numbers

- **116 commits**. Receipt: `git rev-list --count 3f3a0ea50`
- **1 GitHub star**. Receipt: `gh api repos/Kevin-Liu-01/Katagami --jq .stargazers_count (2026-10-30)`
- **5 check files**. Receipt: `gh api repos/Kevin-Liu-01/Katagami/git/trees/3f3a0ea50?recursive=1 | grep -cE <glob>`
- **6.82 commits per active day**. Receipt: `116 commits over 17 distinct commit dates, 2026-10-07 to 2026-10-29`

## Trait

**Variable**. Its weights run 100 to 900, so you set Weight Axis: heavier hits harder, misses more. Receipt: `Katagami@3f3a0ea:README.md:36`

## Moves

- Bezier Points hits for 120, 95% of the time. The site draws the word Katagami as outlines; drag any curve point and the letter reshapes. Receipt: `Katagami@3f3a0ea:README.md:20, 25`
- Weight Axis hits for 135 at wght 600. Each Katagami style is a variable font: one file holding every weight, plus a matching Italic. Receipt: `Katagami@3f3a0ea:README.md:23, 36-40, 51`
- Shared Skeleton restores 60 health. Sans, Round, Text, Serif and Mono are built on one shared skeleton, so the site’s slider morphs a word through all five. Receipt: `Katagami@3f3a0ea:README.md:9, 25`
- Confusables Apart hits for 100. Katagami Mono, the coding style, gives 0, O, 1, l and I clearly different shapes, so code reads without mix-ups. Receipt: `Katagami@3f3a0ea:README.md:40, 57`

- **192.75 commits per active day**. Receipt: `18504 commits over 96 distinct commit dates, 2026-07-27 to 2026-10-30`

## Trait

**Seeded**. The game's simulation is seeded, so this card's damage varies only on a critical hit. Receipt: `claude-of-tanks@ccb2041c4:AGENTS.md:122-124; docs/HOW-IT-WORKS.md:5; src/sim/damage.ts:10,14-15`

## Moves

- Sabot Round hits for 80, 95% of the time and cuts through 50% of a barrier. Fires an armor-piercing dart, one of five shell types, checked against the armor plate and angle it hits. Receipt: `claude-of-tanks@ccb2041c4:docs/HOW-IT-WORKS.md:257-262; README.md:155-157`
- Killcam hits for 65 and finishes a target under 35% health. An X-ray replay shows why a tank died: the shell’s path through its armor and the parts it wrecked. Receipt: `claude-of-tanks@ccb2041c4:docs/FEATURES.md:426-427; docs/HOW-IT-WORKS.md:344-345`
- One Spec raises its Proof. Each tank is one record of armor, gun, crew and look, so the garage, bots and battle always agree. Receipt: `claude-of-tanks@ccb2041c4:docs/HOW-IT-WORKS.md:176-181`
- 14 v 14 hits for 25, 2 to 3 times, 90% of the time. Battles run 7 against 7 and one switch makes them 14 against 14, with bots or with friends in multiplayer rooms. Receipt: `claude-of-tanks@ccb2041c4:src/sim/matchRuleset.ts:942-947; docs/GAME-MODES.md:418-423; docs/MULTIPLAYER-V2.md:788-789`

- **4.69 commits per active day**. Receipt: `61 commits over 13 distinct commit dates, 2026-09-25 to 2026-10-24`

## Trait

**Per-Rule Cap**. Trash rules past their cap refuse to run, so no hit takes over half its Health. Receipt: `mailroom@bc389e255:src/lib/engine/run.ts:125-126; src/lib/policy/schema.ts:69; README.md:58`

## Moves

- Rules hits for 65 and goes first. Rules you can read in one screen become Gmail filters, so new mail is labeled the moment it lands, at no cost. Receipt: `mailroom@bc389e255:README.md:9-10, 23, 26`
- Five Questions hits for 21 five times, 95% of the time. An AI model answers five questions about each email the rules miss, like “needs action”, as probabilities. Receipt: `mailroom@bc389e255:src/lib/ai/triage.ts:43-67; README.md:9-12`
- Ask In Plain Words hits for 105, 95% of the time. Ask in plain words, like “who hasn’t replied to me”, and get an editable Gmail search with ranked results. Receipt: `mailroom@bc389e255:README.md:24; src/lib/search/compile.ts; src/lib/search/rerank.ts`
- Undo restores 50 health. Every run previews first and writes a receipt, and Undo puts labels, filters and policy back, whole or per message. Receipt: `mailroom@bc389e255:README.md:56; README.md:46; src/app/api/runs/[id]/undo/route.ts`

- Stable JSON hits for 57. Results arrive as JSON in one fixed shape, and failures carry an error code agents can act on. Receipt: `Local-Search@7047959:README.md:99-100`
- Fast Search hits for 55 and raises its Pace. Its July 2026 benchmark measured a 148.7 ms median search, mixing fresh searches with answers from saved results. Receipt: `Local-Search@7047959:README.md:104-108; benchmarks/hosted-search-2026-07-21.md`
- Compact Results restores 45 health. Each result is short, a median 53.4 tokens (the word pieces AI models read), so agents can take in more results. Receipt: `Local-Search@7047959:README.md:112-114`

- Health 270, attack 103, defence 119, speed 95

## The numbers

- **4 commits**. Receipt: `git rev-list --count a3f9fdd85`
- **1 GitHub star**. Receipt: `gh api repos/Kevin-Liu-01/Agent-Pets --jq .stargazers_count (2026-10-30)`

- **1 commit per active day**. Receipt: `4 commits over 4 distinct commit dates, 2026-07-20 to 2026-10-08`

## Trait

**Three Repeats**. Pets play every action three times, so moves that hit more than once hit three times. Receipt: `Agent-Pets@a3f9fdd85:site/codex-pet-runtime.mjs:8,50-52`

## Moves

- Sixteen Looks hits for 100 and goes first. An idle pet looks toward your pointer, using 16 drawn poses, one per direction. Receipt: `Agent-Pets@a3f9fdd85:site/codex-pet-runtime.mjs:70-78; site/pet-gaze.mjs:1; README.md:102-111`

- **9 commits per active day**. Receipt: `18 commits over 2 distinct commit dates, 2026-09-12 to 2026-10-16`

## Trait

**Driving Gain**. Firing neurons scale its throttle, so after two turns in play, its Pace rises to 1.5 times. Receipt: `CoTFly@72f5c8fab:src/fly/controller.ts:88-90; docs/FLY-OF-TANKS.md:23`

## Moves

- Inks: 1
- Health 281, attack 103, defence 105, speed 105

## The numbers

- **4 commits per active day**. Receipt: `24 commits over 6 distinct commit dates, 2026-06-14 to 2026-07-27`

## Trait

**Fresh Sandbox**. Each run gets a fresh sandbox, deleted after, so its conditions clear every turn. Receipt: `Sandbox-Arena@0dae422af:lib/arena/orchestrator.ts:37-38, 49-51, 78-80; components/arena/TrialStudio.tsx:266`

## Moves

- Side By Side hits for 40 twice, 95% of the time. Two sandboxes start the same task at once and stream their logs side by side, so you watch the race live. Receipt: `Sandbox-Arena@0dae422af:lib/arena/orchestrator.ts:91-93, 121-128; README.md:7-10`
- Verified Finish hits for 80 and finishes a target under 35% health. Every task ends by checking its output against a known answer, so a fast but broken run scores zero. Receipt: `Sandbox-Arena@0dae422af:lib/arena/scoring.ts:100-101, 117-121; lib/arena/workloads.ts:30, 57, 99, 137, 169, 206, 247, 272, 306 (verifies); app/methodology/page.tsx:88-89`
- Slowest Runs hits for 95, 90% of the time. Rankings can sort providers by the time that 1 run in 20 exceeds, because averages hide rare long stalls. Receipt: `Sandbox-Arena@0dae422af:components/benchmarks/BenchmarkExplorer.tsx:13, 40-44, 93-94; app/benchmarks/page.tsx:45-47; README.md:26-28`
- Session Keys raises a 40% barrier. Your own account keys run one real trial, are read once, expire in ten minutes and never reach logs or the sandbox. Receipt: `Sandbox-Arena@0dae422af:lib/arena/credentials.ts:5-6, 63-70; lib/arena/security.ts:113-120; README.md:36-38`

Receipt: `sevenfold-research-app@d4725a5:api/routes/chatbot_router.py:150-191, 286-328; webapp/src/viewers/ChatViewer.tsx:15-16, 23-64, 66-100, 240-282`
- Saved Workbench restores 50 health. Search, chat, sources and drafts are views of one project, and each keeps its results when you switch views or reload. Receipt: `sevenfold-research-app@d4725a5:webapp/src/hooks/usePersistentState.ts:7-31; webapp/src/context/WorkbenchContext.tsx:56-80, 172; webapp/src/viewers/SearchViewer.tsx:181-182; webapp/src/hooks/clearUserPersistentState.ts:3-9`

## The numbers

- **56 commits**. Receipt: `git rev-list --count d32d1a830 -- src/app/atlas src/app/press public/atlas public/press public/shots/atlas scripts/check/capture-atlas.mjs scripts/build/press-assets.py`
- **6 GitHub stars**. Receipt: `gh api repos/Kevin-Liu-01/Prototemplate --jq .stargazers_count (2026-11-01)`

- **0 check files**. Receipt: `git ls-tree -r --name-only d32d1a830 -- src/app/atlas public/atlas public/shots/atlas scripts/check/capture-atlas.mjs scripts/build/press-assets.py | grep -cE <glob> = 0 of 206 files (Prototemplate's own proof glob; 42 repository-wide)`

## Trait

**Two-Page Spread**. A spread turns two pages, so its moves that hit more than once land at least twice. Receipt: `Prototemplate@d32d1a830:src/app/atlas/(magazine)/_atlas/riffle/flip.ts:16-17 (from the breakpoint width two pages show at once), 74-88 (build(): two pages a leaf on a spread, one page and a blank back on a phone)`

## Moves

- Fluid Cover hits for 90, 95% of the time. Every issue’s cover is a live fluid simulation in its own three colors, stirred by your pointer. Receipt: `Prototemplate@d32d1a830:src/app/atlas/(magazine)/_atlas/gpu/fluid.ts:1-6 (one WebGPU device, a solver per cover, paused off screen); gpu/fluid-wgsl.ts:1-7 (Glyphfield's fluid material in WGSL, printed in three of the cover's inks through an 8x8 Bayer screen); gpu/covers.ts:34-67 (four covers, each with its own colors and seed); ui/Cover.tsx:29-32 (a pointer stirs it while it plays), 115-119 (pauses off screen)`
- Magazine Pages hits for 28, 1 to 4 times, 95% of the time. Each story is laid out as magazine pages of two text columns, and a click turns each page over at the spine. Receipt: `Prototemplate@d32d1a830:src/app/atlas/(magazine)/_atlas/riffle/paginate.ts:1-18 (two text columns a page on a Swiss grid, measured in a hidden page of the same size), 23-30 (MIN_REST: at least 8 words carry on, so no column opens on a lone word); riffle/flip.ts:1-9 (each leaf one rigid sheet, turned on the compositor), 74-88 (two pages a leaf on a spread, one on a phone); riffle/pages.ts:1-15`
- Translated Titles hits for 75. Pick one of nine languages on the globe’s dial, and every story title resets in that language. Receipt: `Prototemplate@d32d1a830:src/app/atlas/(magazine)/_atlas/stories.ts:152-224 (each story's title in nine languages); ui/LanguageRing.tsx:32-44 (the codes round the globe's dial); Landing.tsx:84-99, 221-227 (a pick sets the titles' language and moves the dateline to one of its cities); styles/front-page.css:48-50, 305 (Chinese, Japanese and Korean stand upright); live https://atlas.generaltranslation.com/ja/atlas, 2026-11-01 (front-row-ja.png)`
- Dot Globe sharpens its next hit. A globe printed in dots turns to the chosen language’s city and pins its coordinates, then stops drawing until it turns again. Receipt: `Prototemplate@d32d1a830:src/app/atlas/(magazine)/_atlas/globe.ts:1-7 (an orthographic Earth in 1-bit dots through a 4x4 Bayer screen; it draws once per camera and animates only while it turns); ui/Globe.tsx:27-28 (the pin and its coordinates); ui/Locator.tsx:16-19 (the coordinates flip like a split-flap board)`
