Everything in one conversation that never starts over.

"Hey Bai, how's the restaurant p"

One mind · Two tempos

It answers when you talk. It thinks when you don't.

Agent reactive

Gets it done, right when you need it.

  • You never repeat context: it connects what you just said to everything you already gave it — this note, this thread, this person.
  • No re-explaining who you are. One continuous conversation, with natural pauses between days.
  • If you talk to it, it answers. Fast and faithful: nothing invented, nothing lost, nothing extra.

Brain proactive

Anticipates what's next and keeps you moving.

  • It thinks when nobody's looking: a commitment about to slip, a connection you can't see, a pattern that repeats.
  • Proactivity isn't scheduled messaging — it's what Bai finds.
  • A few messages a day. An ignored one isn't repeated tomorrow, and "not now" is respected. If it finds nothing worth saying, it stays quiet.

One mind, two tempos. Both speeds read and write the same memory — there are no separate worlds to sync.

One brain · Two windows

Talk to it on WhatsApp. Open Space when you want to think.

WhatsApp is enough — talk, forward, ask, recall. Space is the same brain on a bigger canvas: same memory, more room to think.

A WhatsApp / self-sufficient · save, ask, get answers
B Space / same brain · cleaner view, more room to think

"Hey Bai, I have the Atlas meeting with Sarah tomorrow — give me a rundown of what's pending and what I owe her."
Bai noticed
Last time you discussed Atlas, Sarah flagged two blockers . One's been open 9 days — want to unblock it before tomorrow's call?
Notes & tags

You talk. The structure happens on the other side.

You never have to think about organizing — only about doing. No folders to maintain, no templates, no blank page asking you for a method.

You say
"Just talked to María from Innotech, she wants the enterprise plan for March"
What stays
Note #47

María (Innotech) wants the enterprise plan for March.

Client:Innotech Contact:María Priority:High
Follow-up in March

Everything is a note

"What I say lands, and nothing gets lost."

An idea, a task, a receipt, a photo, a voice note. It all comes in where you already talk, and stays as text you can search. The original is kept.

Tags by scope

"Everything about María exists without me filing anything."

Bai tags by scope, not in folders: client, project, contact, priority, status. You don't maintain them — but you can correct them whenever you want.

Search by meaning

"I find it however I remember it."

You don't need the exact words. Ask the way you remember it and Bai brings it back, dated and sourced. If it isn't sure, it says so — it never invents.

Saved views

"I can save a way of looking at my things."

A way of looking, saved with a name: list or board, by tags and statuses. Each front of your life gets one living place to come back to.

Strengths · Shadow loops

You think differently. BAI keeps up.

Your strengths got you here. Your patterns keep you back.

YOUR STRENGTHS ✦ Visionary "I give shape to everything"
YOUR SHADOW LOOPS ✧ Perfection loop "It's never ready"
I've rewritten this intro 6 times. Still not right.
Y
B
Version 2 and version 5 are your strongest — they match the tone you set last week. You're editing in circles now.
One more pass, I think I can nail it.
Y
B
You said that 2 versions ago. This isn't improving it — you're avoiding finishing it. Version 5 is ready. Want me to send it? ✓
YOUR STRENGTHS ✦ Analyst "I understand the problem"
YOUR SHADOW LOOPS ✧ Overthinking loop "I can't stop analyzing"
I found 3 more articles about the best CRM for small teams. I'm saving them.
Y
B
That's 47 articles in 2 weeks. You've narrowed it to HubSpot and Pipedrive 4 times, then restarted the search. Same loop again.
I just want to be sure.
Y
B
Being sure isn't possible. Being informed is — and you already are. Pick one, and test it for 14 days. If it's wrong, you'll know fast. Want me to set up the trial? 🎯
YOUR STRENGTHS ✦ Protector "I take care of everyone"
YOUR SHADOW LOOPS ✧ Overcommitment loop "Everyone's fine... except me"
Can you add to my Saturday: help mom with groceries and drive Leo to practice.
Y
B
That makes 6 commitments this Saturday. You also have your own doctor's appointment — the one you've already moved 3 times.
I'll move it again, mom needs me.
Y
B
You've put yourself last every weekend this month. Your appointment was urgent 3 weeks ago — it's more urgent now. You need to keep this one. 💛
YOUR STRENGTHS ✦ Leader "I've got this"
YOUR SHADOW LOOPS ✧ Procrastination loop "I'll do it tomorrow"
I reorganized my desk, cleaned my inbox, and updated my phone. Productive day.
Y
B
None of those was on your priority list. The investor email is still in drafts — day 3. Want to send it now while you're on a roll?
I'll polish it a bit more tonight.
Y
B
You said that yesterday. The draft is solid — I checked it against your notes. Sometimes "polish" is just another word for "postpone." Send? ✉️

Our principles

BAI is a tool. A powerful tool.

BAI exists to help you make the most of your potential — your ideas, your talents, your ability to make and act on decisions. It stores, analyzes, and communicates information in ways that feel natural, even empathetic. But it's not a person. It doesn't pretend to be one, even when the conversation feels like it could be. BAI won't replace your judgment, your intuition, or the people around you. It's designed to make you sharper, more organized, and more present — so you can show up better for the things and people that actually matter.

BAI is powered by the world's most advanced AI models — including technology from Google and Anthropic. It can make mistakes. But unlike most tools, when you correct it, the correction stays: you won't have to repeat it tomorrow.

Built to serve human intelligence. Not to replace it.

— Luis & Nadia, Founders
