Hello, Signal

A new journal from the team at Orpheus — what it is, why we're starting it, and how it's built.

This is the first post on Signal — a small journal we're starting alongside Orpheus, the AI hearing platform we've been building for the last year.

Orpheus is the product. Signal is the journal. The two have different jobs.

The product is for our customers — engineers, researchers, and operations teams who need to turn spoken language into searchable, translatable text. The journal is for anyone who cares about AI and is tired of skimming twenty headlines a day looking for the few that matter.

What we're publishing

  • Weekly — three to five items from the past week, each with a one-paragraph "so what." Not press releases. Judgment.
  • Essays — longer pieces on building, working, and thinking with AI. What we learn from inside Orpheus, when it generalizes.
  • Field notes — practical tutorials. Cloudflare, Next.js, voice pipelines, model fine-tuning — the things we use every day.

Five languages from day one: English, 中文, Español, Français, العربية. We write in English or Chinese and translate the rest. It's an experiment in publishing globally without an editorial team.

How it's built

// Write a post → commit → push
git add content/posts/hello-signal/en.md
git commit -m "post: hello"
git push

Markdown files in a Git repo. Next.js renders them. Cloudflare serves them. No CMS, no admin login, no database for the writing itself. The publishing flow is git push.

It's intentionally simple so the writing can be the point.

What's next

  • Weekly issue zero — landing in your inbox if you subscribe below
  • An auto-translation pipeline so we can write one source and ship five
  • A /library of older essays once we have a few
