Running Whisper Large v3 Turbo on the phone through Spokenly fixes most of it in 3 to 4 seconds, with the audio never leaving the device. https://segar.me/blog/posts/doximity_precharting.html https://segar.me/blog/posts/doximity_precharting.html Fri, 28 Aug 2026 00:00:00 GMT Using an ambient AI scribe for chart review instead of patient encounters. I read the chart aloud in whatever order I find things and let a custom template impose the structure, which removes the expensive part of precharting. Includes the full template and the prompt rules that keep it from inventing findings. https://segar.me/blog/posts/anki_cards_claude_code.html https://segar.me/blog/posts/anki_cards_claude_code.html Sun, 23 Aug 2026 00:00:00 GMT A working method for generating Anki cards with AI that you can actually trust, covering the HTML rendering bug that eats numeric cutoffs without an error, why ChatGPT alone produces a deck that teaches you the question bank instead of the subject, and what happened when I graded my own AI-built deck against 50 real exam questions. https://segar.me/blog/posts/embedding_model_comparison.html https://segar.me/blog/posts/embedding_model_comparison.html Sun, 05 Jul 2026 00:00:00 GMT I compared five open embedding models to filter keyword lists down to a single niche. The top scorer wasn't the model I shipped, one wrong threshold made the best model look worthless, and the largest gains came from things the encoder never sees. https://segar.me/blog/posts/teaching-claude-my-slide-style.html https://segar.me/blog/posts/teaching-claude-my-slide-style.html Tue, 16 Jun 2026 00:00:00 GMT There's a recognizable look to AI-generated conference slides — the rounded teal cards, the icon-in-a-circle, the drop shadows. I took one of my own talks, had Claude reverse-engineer its design system into a reusable skill, and tested whether the skill could regenerate a deck in my style instead of the default one. https://segar.me/blog/posts/fine_tuning_academic_voice.html https://segar.me/blog/posts/fine_tuning_academic_voice.html Wed, 27 May 2026 00:00:00 GMT How I trained an 8B Llama on my own cardiology papers, from extracting prose out of Word docs, to a first attempt that failed because I trained on single sentences, to a working model that drafts abstracts, methods, and discussions in my style on a Mac. https://segar.me/blog/posts/reconstructing_a_mixbook_movie.html https://segar.me/blog/posts/reconstructing_a_mixbook_movie.html Sat, 23 May 2026 00:00:00 GMT How I traced Mixbook's animated Movie feature to its data API, found that the browser builds the video instead of storing it, and rebuilt a downloadable MP4 from the raw photos and music with crossfades, Ken Burns motion, and the original title text https://segar.me/blog/posts/app_localization_rtl.html https://segar.me/blog/posts/app_localization_rtl.html Fri, 22 May 2026 00:00:00 GMT Notes on adding multiple languages and right-to-left support to a Next.js app, covering logical CSS properties, locale formatting tags, LLM-assisted translation, and two hydration bugs to watch for https://segar.me/blog/posts/supabase_schema_workflow.html https://segar.me/blog/posts/supabase_schema_workflow.html Fri, 08 May 2026 00:00:00 GMT AI coding agents write a new migration file every time they change a table. Here's how a single pg_dump snapshot in the repo keeps Claude Code in sync with the current Supabase schema.
