Recreates the GM merchant area of Silver Knight Town with the original Lineage 3.80C client assets: the mage can walk around, buy scrolls from Pandora, and double-click enchant scrolls to enchant weapons and armor. Success rates, safe levels, blessed +1 to +3, cursed -1, nothing happens above +9, failure evaporation and system messages all follow Enchant.java from the L1J-TW 3.80c server source and the client string table. Runs fully offline as a single package.
A catalog of scores for practicing an instrument: every piece has three parallel layers (staff notation, guitar tab and movable-do numbered notation), with slow-down and section-loop playback, plus Guitar Pro files. The scores themselves are locked (mostly transcribed from other people's arrangements, for personal practice only).
Breaks drawing into four atomic skills (stroke, perspective, shape, and light and shade) and turns them into gamified deliberate practice, with instant geometric scoring on your computer, auto-adjusting difficulty, and a daily trial that targets your weak spots. Five minutes a day to build an artist's hand and eye.
Play it a song. While recording, chords and pitches appear on screen (marked as provisional); after you stop, it re-analyzes the whole waveform and overwrites them with a more accurate final version, and shows exactly where the two versions differ. Transpose freely, paste lyrics into measures, print or save as PDF; for YouTube, generate an analysis file with the local CLI and drop it in. Everything runs in the browser: audio is never uploaded and there are no external dependencies.
Upload a reference image, write an action or plot description, and choose the target duration; the AI automatically breaks it into multiple coherent scenes, generates them one by one, and stitches them seamlessly into a complete short film (with sound).
Learn the seven network layers (OSI model) through play: an overview map where you tap layers to explore, a packet-journey animation showing layer-by-layer encapsulation Data→Segment→Packet→Frame→Bits, and three levels (ordering / matching protocols / scenario judgment) to earn stars. Playable on mobile; progress is saved in the browser.
A Traditional Chinese rebuild inspired by canivibecodeit: 32 well-known paid SaaS products, each judged on whether AI can build a usable personal version in one go (🟢 doable / 🟡 partial / 🔴 has a moat), with a copyable one-shot build prompt, what you would lose by leaving, why people still pay, and moat tags. Live search, categories, MRR ticker and a CRT-green look. Data seeded from canivibecodeit (MIT).
Uses the browser microphone to identify chords, key and scale degrees in real time, and reports your instrument's reference pitch (A4 in Hz and how many cents off). Built-in tuner: pluck a string to see the note name, which string it is, and how many cents it is from the nearest semitone. Supports manually locking the key, movable-do / fixed-do modes (the key menu collapses in fixed-do; the two are mutually exclusive), capo shape conversion (-2 to 11 frets; negative = whole instrument tuned down a half or whole step) and Chinese/English switching. All audio is analyzed locally in the browser: nothing is uploaded or recorded, and there is no backend. Signal processing reuses the same algorithm as the Even G2 glasses version of Chord Ear.
An exhaustive side-by-side of English grammar: the twelve tenses, four ways to express the future, five conditional types, the passive voice, and common-error comparisons. Example sentences are regenerated daily by an on-premise 35B model; the glasses version and the web version read the same read-only API.
Trains your design taste, not color-blindness testing: first see the difference between good and bad through paired comparisons, then learn how lightness, proportion, saturation and the warmth of grays shape a palette's feel, and finally pick your own colors in scenario challenges (finance / children / luxury) and get concrete feedback. 60+ forced choices across the site; only after you choose is your intuition translated into numbers.
Trains an AI with reinforcement learning (PPO) to play QWOP, the hardest running game ever. No rules were programmed: through trial and error plus rewards it learned balance and gait on its own (training average: 157 m). Three modes: play it yourself with Q/W/O/P, watch the AI perform, or race human vs. AI. Realistic runner and athletics track; the same Box2D physics engine is used for training and deployment (train == deploy), and the model runs inference live in the browser.
Cross-platform shell command knowledge base covering Bash, PowerShell, and CMD with searchable, categorized comparisons.
A series of chaptered flashcard study games: bones, muscles, organs, constellations, the solar system, elements and parts. Every card includes Chinese and English names with pronunciation.

A date-indexed catalog of research reports (a directory-style entry point). Reports are laid out independently by agents and published through the CMS zip entry; a database field assigns them to this hub and controls publishing and unpublishing. Includes a system architecture tab.
One book a day: core ideas, quotes in Chinese and English, and a full English translation. A button reads the English aloud in the author's voice with sentence-by-sentence highlighting, and tapping a word looks up its meaning and saves it to your review book.
A handwritten diary that writes back. Write any time; once the ink is absorbed, Tom slowly appears word by word (in Kaiti font) on the line below yours. On-premise AI; supports fullscreen.
Collects English words from book review for Anki-style spaced repetition (SM-2 scheduling, a daily due queue and flashcard grading; a spelling mode has you retype the word before flipping the card to reinforce memory). Also stores English definitions, synonyms and antonyms; tap a word in an example sentence for an instant lookup. For reviewing in the car, one tap turns your words into a short English passage read aloud sentence by sentence in bilingual Chinese-English, continuously and loopable (works on iPad/iPhone too). Playback prefers speech synthesized in order in your own voice, with audio saved in the phone's IndexedDB for zero-network offline replay; articles are kept for 15 days counted from the last read time (reading renews them), all read in Howard's voice.
Enter a description, have AI generate an image suited to be an icon, and convert it at high quality into a complete favicon package (multi-size .ico, PNGs, apple-touch icon, manifest and HTML snippet); supports a letter-mark mode and live tab preview. Runs entirely on-premise.

A ChatGPT-style chat tool wrapping the DGX Spark LLM, with streaming replies, collapsible reasoning, image input (vision), and a code Canvas with live preview and editing.
Generate a video from one image plus a description in Chinese, or take the last frame of the previous clip and extend it (MiniMax H3 on DGX Spark): Chinese prompts work directly without translation, 864×480 / 5 seconds takes about 80 seconds, with a native 32 kHz audio track; an asynchronous queue with live progress, true cancellation, and automatic polling resume after a refresh.
Record one Chinese and one English clip to create your voice; the AI then reads your script in your timbre (Chinese answers sound like you too), sentence by sentence with highlighting that shows where it is, and pausing and resuming does not recompute. Voiceprints are stored only in your browser by default; you can choose to store them on the server after giving explicit consent.
