A sleep log for bodies that don't run on a 24-hour clock.
Not every sleep log is built for rhythms that drift past a 24-hour day. Circadia is Dayah's answer: it takes the pattern you actually have, finds your real drift, and forecasts the next window instead of pretending you will fall asleep at eleven.

In the workshop.
Circadia leads, with Talons close behind; the rest splits into launchable apps, active prototypes, and substrates O+K is dogfooding before offering outward.

Utilities + substrates
Experiments.
Pre-MVP tools still finding their shape. Substrate work with live API or operator surfaces stays in the workshop above; Labs is for experiments that are not launchable yet.
From the journal.
Working notes on the tools and the science behind them.
Flexibility, taught live.
Small online flexibility classes with Dayah. Details are still firming up; the waitlist is open.

The two of us.
Jon builds the systems; Dayah builds the bodies. Also married.
Jon Meriwether
Owl@jon_vs_molochBuilder, writer, and systems tinkerer working on agentic tools, games, archives, and practical digital infrastructure.
Dayah Dover
Kestrel@spicystrippaFlexibility teacher, model, and builder of tools for bodies and rhythms that do not fit the default template.
Questions we get.
What is Owl + Kestrel?
A two-person workshop and estate shell. Jon builds software and infrastructure; Dayah teaches flexibility and built Circadia. O+K is also the first customer for family products like Nest, Chirp, Plumage, Pigment, and Quill; Quill's standalone source MVP combines social notes, longform publishing, and optional verified history.
How do I book a class with Dayah?
Bookings is the current place to join the waitlist. The schedule is still firming up, so this is not a live class calendar yet.
Are the apps free?
Pricing and access are product-specific. Circadia is in open alpha, Talons is free during its alpha, Conduit and Glideslope are alpha downloads, and several substrates are still dogfood or contract-first rather than packaged for public purchase.
How do I keep up with new things?
Join the updates list or follow the journal.
Why Owl + Kestrel?
It is the two of us: a nocturnal systems-builder and a sharp-eyed teacher. One small workshop, two sets of projects.
Updates when there is something to say.
New apps, posts, and class openings from Dayah. This preview signup only asks for an email address.
You're on the list - we'll write when there's something worth saying.
