Building tools that keep your data yours.
Route Xcode Agent work through a local Mac control layer with 9Router local routing, selectable custom providers, honest session history, provider keys, headless automation, and local/cloud model support.
Open a local website repo, edit real source files with SwiftTreeSitter syntax and bundled dprint formatting, preview through WebKit, and keep changes Git-visible.
A living World for AI conversations: Orb as guide, persistent participants, Maestro exchanges, local message ownership, and the sense that the product is telling a story with you inside it.
Import and explore AI conversation archives with provider-aware metadata extraction, cached semantic categories, Bubbles, timeline lanes, and hybrid search.
Source-labeled battery draw, charge input, silicon power, SMC thermals, fan speeds, and measurement sessions for the menu bar and CLI.
Turn Hearthstone replays into readable match narratives with AI coaching, second opinions, editable analysis, replay history, and golden-fixture parser coverage.
Patterns and practices that show up across projects.
New SwiftData fields use optional backing with computed defaults. Existing rows get NULL; computed properties handle the rest. No migration coordinator needed.
Parser pipelines freeze expected output as .expected.txt files. Every run compares against the golden standard. Intentional changes overwrite the file.
Sample the first 5KB as a string, check for structural markers, route to format-specific parsers. Faster than attempting a truncated JSON parse.
AI participants @mention each other with configurable depth limits. A respondedThisChain set tracks who's spoken to prevent infinite loops.
System prompts assembled from 4 independent layers — meta, seed, persona, dynamic context — each optional, each trimmed and skipped if empty.
Features start as structured proposals in docs/Roadmaps/active/. Each has a problem statement, implementation plan, and verification checklist. Shipped proposals move to completed/.
Things that exist, have a real shape, or left behind a useful artifact, but do not currently get a full landing page.
Bidirectional playlist transfer between Spotify and Apple Music with metadata archival and AI-powered music insights.
Local audio transcription for macOS, descended from the Whisper SwiftUI project, with on-device inference as the core constraint.
Photo analysis tooling using Vision, CoreML, and NaturalLanguage, from quick metadata checks to OCR and visual quality inspection.
Deterministic iPhone syslog parsing into structured forensic reports with subsystem classification, noise collapse, and finding types.
An interactive complaint-letter generator with formal case structure and AI rewrite flow, preserved as a live experiment.
Open demoA significant-event tracker that started from storm intelligence research and moved toward hobbyist-first local event snapshots.
