What it is — a personal assistant that's a folder on your disk, not an app: a very thin harness wiring Claude Code to Telegram, cron, and a knowledge base. You text it; it keeps your whole life in Markdown you own. The bet — own the one layer that doesn't churn: your data. The model evolves, skills get superseded, the harness shrinks to glue — even which CLI you run it on swaps out — but your files and chat history stay put. Freedom isn't running the strongest model — it's that everything above your data is swappable. Why Claude Code — open weights can't carry the judgment; ChatGPT/Gemini are closed products, not runtimes you own. Claude Code is stable, strong, ships the runtime as something you keep, has the most reliable tool-calling (and improving), and a flat subscription makes the dozens of tool-calls behind every reply essentially free. The economics — one instance bills ≈ $970/week at list price. It runs on a $100/month subscription, and I run four. The model is the only cost — so it's the one knob you turn down: a cheaper tier, or point a cheaper API like DeepSeek at the same harness to push it lower still. …

I initially thought OpenClaw was just another toy, but after using it for a while, I realized how powerful it is. It reminds me of Tesla's FSD—something you don't trust at first, but once you try it, you'll never go back. …
