THE DISPATCH · No. 01
Summer 2026

A loud quarter at the studio.

A short note on what we built between June and August. A rebuild that paid for itself, a media product shipping every week, and a capability we can drop into your product.

We are an AI product studio. We design, build, and ship AI products and the engineering underneath them, in production, fast. Here is the last three months in one page.

The quarter in brief

116things built and documented, June to August
  • A consumer AI music-video app we build for a client shipped weekly: templates, trending, character replacement, and more.
  • A full engine rebuild from Java to Python, with the bill and the bugs cut at once.
  • A cloud migration and new pipeline APIs behind the scenes.
  • Field notes published openly, from prompt caching to migrating without regret.

Case study · Client engine rebuild

A rewrite that paid for itself.

A client of ours generates AI music videos at volume. The engine that served them was written in Java and had grown brittle. Reverts were frequent, the mobile apps broke in ways nobody caught until users did, and the cloud bill climbed with every view.

We rebuilt the registry from Java to Python, contract-first, and verified it against the real mobile clients before a line shipped. The result was not just cleaner code. It was a service that costs a fraction to run and stopped breaking.

Reverts after cutover, against 28 in the service it replaced
~50%
Less code, for a larger API surface than before
~$0
Media egress, down from a projected $45k to $180k a month

The egress win came from moving an immutable, write-once media set onto zero-egress storage. On the old stack that same traffic was billed at cloud egress rates, a cost that doubles as vendor lock-in. Both mobile apps verified green before launch, because we tested against the actual client decoders instead of trusting a green status code.

Capability · Generative video

Generative video, shipping every week.

For a client, we build a consumer app that turns a song into a video you star in. This quarter it grew from a demo into a product with a weekly rhythm. We treat still-image design and motion as separate decisions: lock identity and story on approved references first, then let the video model perform the shot. It keeps quality high while the pace stays fast.

// shipped this quarter
  • Campaign templates so a new video starts from a proven recipe, not a blank canvas.
  • Character replacement that puts the right person in the scene, consistently across shots.
  • Trending and leaderboards that turn creation into something social.
  • Golden frames and treatments that set the look before a single second renders.

The lesson we keep proving: approve the still before you pay for the motion. It is the difference between a product that ships weekly and one that stalls in revisions.

Capability · Live collaboration

Co-browsing, built into your product.

Sometimes two people need to be on the same screen at the same time. A support agent guiding a customer. A team reviewing a design together. A seller walking a prospect through a flow. We have built the engineering for this and can add it to your product.

It runs peer to peer, so cursors, edits, and presence move in real time without a heavy media server. Small rooms need almost no infrastructure. When you outgrow that, the same design graduates to a forwarding server without a rewrite.

// what it unlocks
  • Guided support. See what the customer sees and point at it, instead of reading steps aloud.
  • Collaborative editing. Many people in one document or canvas, with live cursors and safe concurrent edits.
  • Live onboarding and demos. Walk a new user or a prospect through the real product, together.

We ship it with the parts that usually get skipped: presence, reconnect handling, and concurrency that does not throw away someone's work when two people touch the same thing. If live collaboration is on your roadmap, this is weeks of work we have already done.

From our notebook

What we wrote down.

We publish the useful parts of how we work. A few pieces from this quarter, open to read:

We ship our own tools, too.

We build for clients, and we run our own products alongside that work. Three you can use today, free to try:
