AI Detective
Analyzes text and estimates how likely it was written by AI, a human, or a mix of both—breaking the result into AI / Human / Edited / Unknown percentages with a confidence score and supporting signals. Also validates citations against real databases. Paste, upload, or batch-process documents using your own Anthropic API key. No account required.
Juggler
A drag-and-drop to-do list that nests tasks inside tasks, so a single project can hold its own sub-tasks, deadlines, and notes. Color-code, set reminders, and reorder anything instantly—all stored privately on your device, never on a server.
WinScribe
A transcription tool modeled on classic tape transcription machines. Play and control audio or video while typing your transcript—all in one window. Hands never leave the keyboard. Output is standard RTF, ready for any word processor.
WinScribe II
The browser-based successor to WinScribe. Load an audio file, play it back with transcription-friendly controls—loop, back-space, variable speed—and type your transcript alongside it, all in a retro cassette-deck interface. Nothing is uploaded or stored; your audio and transcript stay on your device.
PC Sweeper
PC Sweeper sits in your Windows tray and cleans up after you. It clears the clipboard automatically so copied passwords and private data don't linger, empties the Recycle Bin on your schedule, and strips formatting from copied text with one hotkey. Free, portable, no admin rights, no tracking.
Notorious
A single-file, Mac-styled notes app that runs entirely in your browser. Folders, rich text, checklists, tags, and note-to-note links — all the everyday core of Apple Notes, without an iCloud account or platform lock-in. Everything saves automatically, right on your device.
