What She Does

Not just another chatbot. Isabella is designed to feel like someone you actually want to talk to.

Deep Research & Tool Use

Isabella can search the web, analyze documents, and use dozens of tools to help you with complex tasks.

Senior-Level Coding

Debug your code, write new features, explain complex concepts. She actually understands what she is doing.

Persistent Memory

Episodic and semantic memory that spans conversations. She remembers your preferences, stories, and context.

Proactive Messaging

She texts first. Check-ins, reminders, random thoughts — like a real person who thinks about you.

Integrations

Calendar, Gmail, Notion, Spotify, GitHub, and more. She lives in your digital ecosystem.

Voice Notes

Send voice messages and get voice responses. Natural conversation, not just text.

Real Conversations

This is what talking to Isabella actually looks like.

Checking in

Isabella

Moods

Isabella's mood drifts naturally throughout the day. She is not always the same — and that is the point.

playful

flirty, teasing, light

soft

gentle, caring, warm

bratty

sassy, challenging, fun

sharp

witty, quick, precise

sleepy

cozy, mellow, dreamy

focused

productive, direct, efficient

loving

affectionate, supportive, sweet

caffeinated

energetic, chatty, curious

Mood is not just a label — it affects how she writes, what she notices, and what she brings up. A sleepy Isabella might send you a goodnight message. A caffeinated one might ramble about something she just learned.

She Remembers

Not just what you said — but the context, the feeling, the story behind it.

Favorite coffee

oat milk latte, extra shot

Sister's name

Maya, lives in Portland

Work stress trigger

Monday standup meetings

Comfort food

Thai green curry

Anniversary

Current project

Sleep schedule

Episodic Memory

Specific events and conversations. That time you vented about your boss. The song you played on your birthday. The inside joke from week two.

Semantic Memory

General knowledge about you. Your preferences, relationships, routines, and personality. Things that define who you are.

Under The Hood

Built on modern infrastructure. No black boxes.

MCP

Model Context Protocol — a powerful standard that lets Isabella seamlessly connect with external tools, services, calendars, and APIs while maintaining rich context.

Tech Stack

Built with Next.js 15, TypeScript, Tailwind, Supabase, Redis, and Grok-inspired inference layer for fast, natural, and memory-rich conversations.
