AI chat that
actually
remembers.
Projects with persistent context. Smart routing that picks the right model for each question. 200+ models, no subscription, export everything. Free to start.

Eight skills
Not just chat.
Structured thinking.
Each skill changes how the AI approaches your question — different system prompts, different priorities, different output formats.
Ask
Direct answers. No unnecessary preamble.
Plan
Step-by-step plans with timelines and dependencies.
Interview
The AI asks you questions to extract requirements.
Review
Critical feedback on copy, code, strategy, or proposals.
Brainstorm
Divergent ideas without premature filtering.
Summarize
Key points from long content. No filler.
Decision
Structured comparison of options with trade-offs.
Research
Web search, source tracking, evidence-based answers.
Persistent context
Every conversation
knows where you left off.
Projects hold sessions together. Background, objective, industry, and tone persist across every conversation. Two memory layers — user memory (global) and project memory (scoped) — so the AI recalls what matters without you repeating it.
What kind of marketing copy?
What's your brand?
Who's your audience?
What's the tone?
Every conversation starts from scratch.
Based on your project context:
B2B SaaS, technical audience, direct tone —
here are three options for the hero section,
each leading with the outcome your users care about.
Context + memory = no repetition.
Smart routing
The right model for
every question.
Otinaru reads context and intent, then routes to the best model automatically — vision models for images, research models for web search, fast models for quick answers, powerful models for complex reasoning. You can also pick manually or compare side by side.
Auto-routing
Detects images, code, research tasks, and complex reasoning — picks the best model without you thinking about it.
Compare mode
Run two models in parallel on the same prompt. See both answers side by side, pick the best.
