We build Bai: a personal agent and an operative memory that lives in your WhatsApp and makes sure nothing important slips away.
Bai is a personal agent and an operative memory. It works alongside you day to day from WhatsApp and makes sure nothing important gets away from you. It's reactive and proactive — it answers when you talk to it, and it gets ahead of things when it matters — so you stay in control of your world and focus on what actually counts.
You tell Bai something once — an idea, the project you're working on, a receipt, a deadline — and it lands. Bai turns it into a note, connects it by scope to the rest of your world, and brings it back however you remember it. There's nothing to file and no system to maintain: you speak naturally, and the structure happens on the other side.
Before intelligence, memory. Reasoning is what the models already do well, and it improves on its own. What we fix is the distance between a person and their own information.
Capable people with too much on their minds and too little time to organize it. Things slip through the cracks. The day ends without knowing if anything really moved. Ideas scatter across notes, chats, and email.
And every AI assistant starts from zero: today it doesn't know what you discussed yesterday, so you re-explain who you are, every time. Productivity apps don't help either — they need you to already be organized just to start organizing.
Entrepreneurs, freelancers, and independent professionals — people juggling several projects or clients at once, with no team and no assistant behind them, for whom WhatsApp is already the main channel.
They're not broken and they don't need fixing. They don't need to learn to be organized, and they don't need another app to teach them productivity. What they lack is a place where all of it can land. Bai doesn't add capacity — it clears the path.
Three products on one shared memory. Bai Life is the one we sell to individuals; the other two carry the same engine into working contexts.
Our first product, and the one this site is about. A personal agent and an operative memory that lives in your WhatsApp: you tell it something once, it files it, and it brings it back however you remember it. $9/month, 9 days free.
The same memory, shared by a team. Everyone talks to it from the channel they already use, and the context stays with the team instead of scattering across private chats.
The front desk: it answers, qualifies, and routes the people who write to a business, and hands over to a human with the whole thread already in context.
If it needs a manual, it's poorly designed. No setup, no templates, no empty page asking you to be organized before you can start.
Your data is yours. Encrypted in transit and at rest. We don't sell information. Period.
Bai is a powerful tool built to serve human intelligence, not to replace it. It doesn't pretend to be human and never fosters dependency.
