Meet Biblo.

Biblo is a personal AI fitness agent. You can use it through iMessage today, with a companion app planned to bring progress, plans, and connected-account controls into the same experience.

The current texting experience helps you track food with photos and plain-language messages, get calorie and macro estimates, and keep track of your day.

The basic service is currently free on iPhone.

Why we're building Biblo

Wanting help with your health and fitness should not mean managing a collection of tools that each need the same explanation.

A food log can tell you what you ate. A training plan can tell you what to do in the gym. But your day rarely follows either plan perfectly. Lunch changes, a meeting runs late, or you have less time to train than you expected.

We want a personal agent that can help in those moments, using the context you choose to share rather than making you begin from scratch every time.

What Biblo does today

Send a meal photo or describe what you ate. Biblo replies with estimated calories, protein, carbs, and fat. You can add details, correct a portion, and ask for your daily totals in the same iMessage conversation.

The personal agent we're building

The longer-term goal is help that connects understanding to action.

That could mean adjusting a workout plan when your week changes, helping you choose a meal that fits your preferences, or placing a food order you've approved.

A personal agent should be useful because it understands the task and the person, not because it has another chat box.

Messaging and a planned companion app

Text Biblo to log a meal or ask for help. The planned companion app will give you a place to review progress, manage plans, and control connected accounts and permissions.

The goal is one personal agent you can interact with in the way that fits the task. A quick message can handle a meal log; a visual view can make a longer plan easier to understand.

The current iMessage experience does not require a separate download. The companion app is planned, not available to download yet.

The team

Biblo is led by founder Manil Lakabi. Our team has worked on AI tools that create and use software, and we are now applying that experience to a personal agent for everyday life.

The company is backed by Y Combinator and participated in its Fall 2024 batch. Biblo is our current product and public brand.
