Beautiful output.No lock-in.
Two AI tools — one for design, one for conversation. Pick any model, control costs, own everything you create.
No credit card · No subscription · Export always
First proof
Studio: design that doesn't look AI-made.
Generate prototypes, decks, and landing pages you can actually export. Every generation goes through quality gates — no generic layouts, no recycled aesthetics.
Second proof
Chat: conversations that work for you.
Persistent projects. Focus areas that change how the AI thinks. Research, plan, review — with any model, no lock-in.
Here's my review:
The Otinaru principle
Every tool we build follows the same rules.
AI tools generate fast — but most trap your output, model choice, and workflow. Otinaru is different by design.
Your model choice
Switch anytime, no lock-in
Your cost control
Prepaid credits, no subscription
You own the output
Export everything on every plan
Full transparency
Token usage visible, no hidden fees
Studio
studio.otinaru.com
Generate prototypes, decks, and landing pages with quality gates. Clean HTML/CSS/JS output — always exportable.
Chat
chat.otinaru.com
Persistent projects, focus-aware conversations, multi-model compare. No subscription, no lock-in.
Studio ↔ Chat — shared context
Link a Chat project to your Studio design. Chat reads your file structure and design system; Studio knows your conversation objective and background. Same account — no copy-pasting between tools.
No Lock-In
Choose your model. Change your mind.
Not every task needs the most expensive model. Pick the right one for the job, switch freely, and never get locked into a single provider.
