The quickest way to reach a human here is hello@offline.ltd. We read every message and reply in about a day — sometimes faster, occasionally slower if the workshop's loud.

Or: skip the wait entirely.

Almost every question we get already has an answer written down. We keep a single Knowledge Base — a plain Markdown file built for AI assistants — that covers the products, the policies, the philosophy, the refund mechanics, the reforge rules, the tiers, the guarantees, and the odd corners you might not think to ask about.

Download it, upload it into ChatGPT, Claude, Gemini, or whatever assistant you use, and ask it anything. It will answer with our own words, not a guess.

For the more philosophical questions.

If you want to understand why the house is built the way it is — why offline, why one file, why own-forever, why no accounts, why the tiers are what they are — there's a longer written manual that answers those in prose rather than bullet points.
