Lands on Telegram at 07:30, in time for my ride to work. About $0.10 an episode.Thu, 01 Oct 2026 00:00:00 GMThttps://arthurpfz.com/#telegram-capture-botshttps://arthurpfz.com/#telegram-capture-botsTwo Telegram bots for getting things out of my head and inbox: send a tweet, article or YouTube link and get a clean markdown note in my vault; or record a voice memo and get it transcribed and filed. Same surface, two jobs.Sat, 05 Sep 2026 00:00:00 GMThttps://arthurpfz.com/archive/the-coach-that-watches-the-datahttps://arthurpfz.com/archive/the-coach-that-watches-the-dataAn AI triathlon coach that grades every workout against your fitness, writes next week's plan on its own, and lives entirely on infrastructure I control. The architecture, the components, and the three patterns that hold it together.Tue, 14 Jul 2026 00:00:00 GMThttps://arthurpfz.com/#brain-digesthttps://arthurpfz.com/#brain-digestEvery Monday at 08:00, one recently updated page from my vault comes back to me as a ~150-word Telegram dispatch: one tension, gap or surprising fact, not a summary. A digest fails if it could have been written a month ago. One n8n workflow.Thu, 14 May 2026 00:00:00 GMThttps://arthurpfz.com/archive/stop-typing-second-brainhttps://arthurpfz.com/archive/stop-typing-second-brainA personal LLM-friendly wiki: Obsidian on the read side, Claude on the write side, QMD for full-text search, Syncthing mirroring Mac ↔ VPS with no cloud middleman. Hermes, XBookmarks and Voice Notes all write into it. The architecture, the schema, and the three patterns that hold it together.Mon, 27 Apr 2026 00:00:00 GMThttps://arthurpfz.com/#voice-noteshttps://arthurpfz.com/#voice-notesTelegram voice memo → Whisper transcription → Claude categorisation (idea / todo / other) → markdown file written into my Obsidian vault, with an undo button. Whole pipeline is one n8n workflow.Thu, 23 Apr 2026 00:00:00 GMThttps://arthurpfz.com/#hermeshttps://arthurpfz.com/#hermesVPS-side agent with two personalities: 'vault-aware' answers questions over my knowledge base in read-only mode, 'vault-writer' drafts new pages into a sandboxed inbox folder. Talks to me on Telegram. Runs on Grok via OpenRouter.Sun, 19 Apr 2026 00:00:00 GMThttps://arthurpfz.com/#relayhttps://arthurpfz.com/#relayWebhook-based command runner so a phone-side Claude (or just me, on a train) can restart a container, tail logs, redeploy, or run an arbitrary script on the box. Auth + audit trail + a small allow-list of operations. n8n is the dispatcher.Wed, 15 Apr 2026 00:00:00 GMThttps://github.com/Arthurpfz/text-polisherhttps://github.com/Arthurpfz/text-polisherSystem-wide hotkey: select text in any app, hit a key, get a polished rewrite pasted in place. V2 added language + tone toggles in the tray icon. V3 added push-to-talk dictation via local Whisper. The amount of mid-typing context-switching this killed is embarrassing.Fri, 13 Mar 2026 00:00:00 GMThttps://arthurpfz.com/book-summarieshttps://arthurpfz.com/book-summaries13 book summaries on product, behavioral science, and strategy. Notes I took to flatten my forgetting curve.Sun, 08 Nov 2020 00:00:00 GMT
