An open-source local media and course archive workspace with a guided CLI, browser interface, persistent queue, and no hosted processing backend.

Many download tools force users to choose between approachable interfaces and powerful controls, while cloud-based workflows create unnecessary privacy concerns.
The queue persists plans, progress, output files, audit events, and cancellation requests across CLI and daemon processes.
A durable local queue gives the browser and CLI one source of truth without adding a hosted service.The companion binds to 127.0.0.1, validates Origin, uses a secure local session, and restricts output-file access.
The local network boundary is part of the product’s privacy model, not merely a deployment detail.Validated DownloadPlan objects are serialised into jobs, and running work is reclaimed after a daemon crash.
The queue owns recovery so a terminal closing does not make a user restart the whole workflow.The public Vercel site is documentation only. The installed app starts a loopback service, while the CLI, browser interface, daemon, SQLite queue, yt-dlp, and FFmpeg remain on the user’s machine.
Network extractors are mocked or served by local fixtures, so required tests never contact media websites. The public release keeps YouTube and MIT OpenCourseWare paths conditional or evidence-labelled while protected-provider output, browser handoff, signing, and onboarding remain separate gates.
The next quality step is a moderated onboarding round with non-technical desktop users, focusing on installation, the local privacy boundary, and queue recovery language.
A relationship operating system that turns professional contacts into a queryable, visual, and bilingual workspace.
