YouTube needed a pre-watch filter.
A local attention ROI layer that helps decide whether a video deserves deep focus, a scan, background listening, or a skip.
Research, systems, and tools for the open internet.
Independent projects at the intersection of infrastructure, information, and interface. Documented in public. Built for longevity.
Systems age. Interfaces calcify. Information decays.
YouTube is where I learn, relax, research, and follow curiosity. KoalaTube asks whether the next click is worth the attention before it becomes an hour. Some videos still need an exoskeleton while I watch. The whole day needs a second layer after I sleep: a searchable LLM Wiki record of what I watched, what each video said, and which notes deserve another pass in Obsidian. An apartment renovation had a similar shape: I needed one good scan to design from, not a monthly subscription for a tool I would use once. LoopCam came from the gym, where a single interruption can make me lose the rep count, the set count, and the rhythm of the workout.
A local attention ROI layer that helps decide whether a video deserves deep focus, a scan, background listening, or a skip.
A layer around videos that helps me understand, review, and keep the knowledge without breaking the watch flow.
Every midnight, yesterday's videos become a daily Markdown trail: titles, scripts, outlines, Jingdu notes, and explicit gaps.
Open the phone, scan the space, export the file, and walk away. No login. No ads. No recurring fee for a once-in-a-while job.
If the phone is already on a tripod, it should count the reps, keep the set visible, and record the screen when I want a record.
[ 06 Projects ]
The same small-tool discipline under different surfaces.
Local-first promises are part of the product surface.
Project pages separate public website analytics from the tools' local product data boundaries.
The tools stay useful without adding account walls, ad SDKs, or subscription scaffolding.
A watched video becomes notes. A room scan becomes a file. A workout keeps its count.
The index stays small on purpose: public projects, plain boundaries, and enough build record to show where each tool came from and what it is allowed to touch.
