Your personal AI fitness agent.

Biblo is a personal AI fitness agent. Today, you can use it through iMessage to send food photos or describe meals, get calorie and macro estimates, and keep the conversation going as your day changes.

We're building a personal fitness agent that can connect that everyday context to coaching, planning, and actions you authorize.

Free to use · Available on iPhone through iMessage

What is an AI fitness agent?

At Biblo, we use “AI fitness agent” to describe a personal assistant that can help you understand what you've done, decide what to do next, and eventually carry out approved tasks.

Those are different jobs. Estimating the macros in a meal is tracking. Helping you decide how a meal fits your goals is coaching. Placing an order you have approved is taking action.

Our ambition is to connect those jobs without making you manage a separate tool for each one.

What you can do with Biblo today

Log food with a photo or a message

Send a picture of a meal, or type a description. Biblo replies with estimated calories and macros, including protein, carbs, and fat.

Add the details a photo misses

Tell Biblo about the portion you ate or an ingredient it could not see. “I only ate half” and “There was dressing on the side” are details you can add in the conversation.

Keep track of the day

Ask for a summary of what you have logged or your daily calorie and macro totals. You do not have to turn each question into a new workflow.

See the step-by-step food-tracking guide.

From tracking to useful action

Our vision goes beyond describing a meal after you've eaten it.

We want Biblo to help with questions like what to eat when your plans change, how to fit training into your week, or which meal matches your preferences. With your permission, an agent could then help carry out a decision, such as ordering the meal you selected.

The point is not to make decisions behind your back. It's to make the next step easier, with you in control of what gets done.

Why iMessage?

Food and fitness happen throughout the day. A meal photo, a changed portion, or a question about your total is naturally a message.

The current Biblo experience works in iMessage on iPhone. You can send a meal or ask a quick question without a separate download.

A companion app alongside messaging

A companion app is planned for the parts of fitness that benefit from a visual view: reviewing progress, managing plans, and controlling connected accounts and permissions.

Messaging and the app are intended to work together as parts of the same Biblo experience. Texting makes quick interactions easy; the planned app gives you another way to see and manage what Biblo is helping with. The app is not available yet.

Try the current experience

You do not need to understand AI agents to use Biblo. Send a photo of your next meal or tell it what you ate.
