We build software
like it's a craft.
TypeScript. Deno. Web standards. We're a small team in Ohio with strong opinions about how software should be made — and we hold ourselves to them. No unnecessary dependencies. No 500kb bundles. No features we can't explain.
Coming soon — early access open
Image generation
built around the result.
Miru is an AI image generator for people who care about what comes out the other end. Generate with Kiri — free, no catch — or go deeper with Tsuki, Yume, or Hana for more nuanced output. Credit-based billing, so you pay for what you use. A gallery to collect, organize, and share the work worth keeping.
Four generation models. One free tier.
No volume incentive to generate garbage.
Free to start
Generate with Kiri at no cost.
No trial period. No credit card to start. Kiri is the free model — capable, honest about its limits, and always available.
Credit-based billing
Pay for what you use.
Four models, each priced to reflect their capability. No subscriptions. No monthly minimums. Your credits don't expire.
A gallery worth keeping
Collect, organize, share.
Miru is built around the output, not the generation queue. A real gallery for work you want to keep — not just an activity feed.
How we build
Four things we believe — and build accordingly.
01 /
Keep it small.
We don't add features to feel productive. Every dependency is a decision. Every abstraction is a bet. We'd rather have ten things that work than a hundred things that mostly do.
02 /
Write code worth reading.
Clever is not a compliment here. We write for the developer who comes next — which is usually us, six months later, at 11pm. If a function needs a comment to make sense, the function needs rewriting.
03 /
Earn the user's trust.
No dark patterns. No manufactured urgency. No tracking we don't disclose. If you use a psyn product, we are not working against you — and we've written the code to match that promise.
04 /
Ship when it's ready.
We take our time. Not because we're slow — because we've seen what shipping fast without thinking costs in maintenance debt and user trust. We'd rather miss a deadline than ship something we'd have to apologize for.
About psyn.
psyn is a software company based in Ohio, started in March 2026. We build products we'd want to use ourselves — the kind where the details are right and the privacy policy is actually readable. Our stack is Deno, TypeScript, and web standards. We stay close to the platform, keep our dependencies lean, and treat the codebase as something worth taking care of.
We're small by design. We don't have a growth team. We don't run ads. We build things, ship them when they're ready, and let the work speak. If that sounds like how you think software should be made, you're in the right place.
Built in Ohio. Incorporated March 2026.
