Guitar Theory Studio
Stop memorizing shapes. See the theory.
What it does
Ten daily theory questions, a fretboard that draws any scale, progressions with smooth voice leading, guided practice - every tool free, no account. GTS Pro trains you on what you miss. And Ask's AI can't hallucinate: it opens tools, never draws notes.
Interactive guitar theory tools: fretboard explorer with CAGED shapes, chord progression builder with smooth voice leading, a free song-progression library, arpeggios, practice loops, and an Ask tab that opens the right tool from a plain-English question. Free in your browser, iOS, and Android.
Every shape you've memorized is one link in a longer chain: CAGED connects to scales, scales to intervals, intervals to chords, chords to progressions, progressions to arpeggios. Guitar Theory Studio draws the whole chain on a physically accurate neck — computed live by one theory engine, so change the key and everything moves together. "Show me D Dorian." "12-bar blues in E." "Set me up a beginner practice loop." Ask reads the question, opens the right tool, and configures it — the answer is the app itself, not a wall of text. Every note it shows is computed by the same theory engine, so it can't hallucinate a fret. Pick a key and the diatonic chords are laid out with Nashville numbers and…from guitartheorystudio.com

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
