Code is written on a glass editor floating in dark space, carried away as particles of light, computed, and returned as finished work. Scroll to follow the whole run.
Daily exercises cover calculation, judgement, memory, attention, visuospatial skills and reasoning. Includes IQ-style puzzles (number sequences, shape matrices, analogies and logic) and delayed image recognition after an intervening exercise.
A limited-beta Web / PWA app for PCs and smartphones, hosted on Cloudflare Pages. Light and dark themes, optional BGM, locally saved history, and on-device display and sound settings.

Mymews
人が確認したRSS / Atomを集め、ローカルAIで朝刊を作る個人用ニュースリーダー。
A personal local news reader that turns approved RSS / Atom feeds into a morning edition with optional local AI.
Only sources and feeds whose usage terms have been reviewed by a person are eligible for collection. Articles are stored in SQLite and can be browsed with category and attribute filters. AI starts disabled; when a configured local GGUF model is enabled, it can classify, summarize, score, and build a small morning edition.
Source Policy history is retained and current permissions are checked across collection, storage, AI, and display. It does not use external AI, fetch images, or automatically retrieve full article bodies, and its web UI runs locally on 127.0.0.1.

ローカルで動く行動・記憶管理エージェント。
A local agent that keeps track of actions and memory.
A local LLM interprets plain-language input, then tools handle todos, schedules, memos, conversation logs and activity logs. An event bus and controller keep input separate from processing, and reading is kept apart from writing.

暗号化した保管庫を正本にするローカルメモアプリ。
A local note app whose source of truth is an encrypted vault.
Notes are held in an encrypted vault, with import from Markdown, TXT, JSON and ZIP and export back to Markdown. The search index can be rebuilt from the vault, and it includes encrypted backup plus a read-only integrity check. It is not an Obsidian-compatible vault.
Microphone audio is transcribed by a local Whisper model, then either left on the clipboard or pasted into the foreground app after an explicit confirmation. Neither the audio nor the text leaves the machine.

voice_logger
話した内容をその場で文字にして書き溜める記録ツール。
A logger that turns what you say into text as you speak and keeps appending it.
It picks out just the stretches where you are actually speaking, runs them through local speech recognition, and appends them line by line to a JSONL file for the day. That JSONL is the only stored format: there are no intermediate files and no conversion layers.
Daily records of temperature, blood pressure, pulse, weight, body fat, meals and activity, with charts. Everything lives in a single SQLite file, and the default configuration binds to localhost for same-machine use only.

公開一時停止（2026年10月23日～・安全確認／修正中）
Temporarily unavailable (since October 23, 2026; security review and fixes in progress)
No server or Docker setup: open the published URL and add it to your home screen. Records stay on the device, with backup and CSV export. It is currently published as a beta.
It processes at most one queued prompt per run, and handles generation, analysis and adoption from a desktop UI. By design it never deletes, moves or overwrites audio that has already been generated.
Edit notes by hand in a piano roll and save or load standard .mid files. Patterns are generated deterministically from a scale and rhythm specification, with text input via a local LLM as an optional extra. All timing is handled in ticks.

自分のPC1台の内部だけを見る、ローカル完結の監査ツール。
A self-contained audit tool that looks only inside my own PC.
It watches only the traffic this machine itself sends, plus the processes, firewall settings and backup state on this same machine. It does not look at other networks or anyone else's devices. What it records stays in a local SQLite file and is reviewed through a read-only timeline. It detects and records only: nothing is blocked or repaired automatically, and every judgement is left to a person. It needs no internet connection and no administrator rights, and it never touches the kernel or drivers.

「体験を英語で話す装置」を目指した試作。
A prototype aimed at being a device for talking about your own experience in English.
A speaking-practice prototype designed to avoid feeling like a study app, prioritising natural phrasing and a one-minute length. There is no scoring or testing. It is still a single-HTML prototype.

USB_checker
USB機器の構成変化と打鍵の異常を見るWindows向けの検知ツール。
A Windows detector for USB configuration changes and typing anomalies.
It compares the interface layout of connected USB devices against an approved baseline and reports changes, and separately looks at keystroke timing statistics for signs of automated typing. It only detects and records: nothing is blocked. Approvals are always made explicitly by the user, never automatically, not even the first time. It needs no administrator rights, makes no network connections, and has no third-party dependencies. Key input is never interpreted and is not retained beyond the moment a key is held.

Favorites_Launcher
登録したYouTubeのリンクを整理して、選んだ1件を既定ブラウザで開くランチャー。
A launcher that organises saved YouTube links and opens one in the default browser.
It imports bookmark HTML from a browser, folder tree and all, then merges duplicates by video ID. A single video can belong to several lists, with search, sorting, and an ordered or shuffled queue. It does not play anything itself: it opens the chosen video as an ordinary YouTube page in the default browser. Embedded playback and API integration were deliberately left out of scope.

MeishiCraft
日本の名刺をレイアウトして、PNG・PDF・印刷まで出せるWindows向けのデスクトップアプリ。
A Windows desktop app for laying out Japanese business cards and exporting them to PNG, PDF, or print.
It handles the standard 91x55mm card in either orientation, with a front and a back. You can place text, images, QR codes, shapes, and lines, then move, resize, and reorder them, with undo and redo. Text that overflows its box is flagged. Positions are kept in millimetres, and the same drawing rules are used on screen, in PNG, in PDF, and when printing, so the output matches what you designed. A card is saved as a single file you can reopen and keep editing. PNG exports at 96, 150, or 300 DPI, and PDF exports at true size, either as one card or ten to an A4 sheet.

QRCodeMaker
入力した内容を、読み取り可能なQRコード画像にするWindows向けアプリ。
A Windows app that turns what you type into a scannable QR code image.
It covers web addresses, email, phone numbers, SMS, plain text, Wi-Fi credentials, and contact cards, saving each as a PNG that a phone camera can read. Load a CSV of contacts and it will produce a PDF with one person per page, or one PNG file per person, in a single run. It never connects to the internet, so nothing you type is sent anywhere: everything happens on your own computer.
No server and no installation: copy one HTML file into the Files app on an iPhone and tap it to open. It reads the bookmark HTML, JSON, and CSV that the Windows version exports, working out the format from the file itself, then lets you browse, search, edit titles and links, and create and assign lists. Edits can be written back in a format the Windows version reads. Data being edited lives only in memory while the page is open, with no browser storage used, so the file you export is the record. The display follows the light or dark setting of the device.

Shomei_photo_maker
手元の写真を、規格どおりの寸法の証明写真に整えるWindows向けアプリ。
A Windows app that turns a photo you already have into an ID photo at the required size.
Load a JPEG or PNG, then choose a spec: Japanese passport 35x45mm, resume 30x40mm, or a custom size given in millimetres. The frame stays fixed at the centre of the screen and the photo is what moves, scales and rotates into place, with undo and redo. Export at 300 or 600 dpi as JPEG, PNG or PDF, including sheet layouts on L-size or A4 paper with margins, spacing, counts and cut lines. There is no image analysis such as face detection or background removal, and it makes no network connections. Exported images carry their resolution, and the EXIF and GPS data of the original is not passed through. It does not judge whether a photo meets a given standard, so checking the requirements of wherever you submit it is left to you.

LocalFrame
Windows上でローカル動作する動画編集ソフトの試作。
A prototype video editor that runs locally on Windows.
Video and audio tracks are edited on a single 1920x1080 / 30fps / 48kHz sequence. Clips are dragged in from a media pool, moved and trimmed, joined with cross dissolves, animated with keyframes for position, scale, rotation, opacity and volume, and adjusted with basic brightness, contrast, saturation and gamma, all with undo. Preview and export hand a fixed render plan to an external FFmpeg. Projects are saved as .lframe files. FFmpeg and ffprobe have to be installed separately. It is still a prototype, and parts of it have not yet been verified in use.
It analyses new mail subjects, sender display names and domains, and body text when needed, recording reasons for suspected brand impersonation in a local audit log. Automatic moves are off by default; when enabled, HIGH and MEDIUM results can be moved to designated existing folders. It does not delete messages, rewrite their bodies, or create folders. The minimum Thunderbird version declared in the manifest is 154.0.
It compares source and destination folders, classifying files as new, changed, identical, or destination only, so you can select new and changed files to copy. The source is read only, and destination-only files are not deleted. SHA-256 and other checks detect changes since comparison, and copied contents are verified. It is built with Python and PySide6.
