The builder behind every LetBe.ai product

Build AI workflows without API keys, servers, or surprise bills.

Design it visually, try it in a chat, publish it as a live endpoint. The models are built in and everything runs hosted. You bring the idea.

No API keys

The models are already here. No provider accounts, no keys to paste, no quota dashboards to babysit.

Nothing to host

Your workflow runs in our cloud from the first click. Publish it and call it from anywhere, or share it as a chat.

No surprise bills

A prepaid wallet you top up when you choose. Top-ups never expire, and nothing charges behind your back.

From idea to running in three steps

No setup day. No deploy day. Just the idea, assembled.

1

Assemble it

Drag ready blocks: models, prompts, decisions, loops, audio in, voice out, your documents.

2

Try it in chat

Talk to your workflow while you build it. Fix the weak step, not the whole thing.

3

Publish it

One click makes it a live endpoint you can call from your code, your site, or your tools.

Outgrown per-task pricing or a self-hosted server?

If your automation bill surprises you monthly, or your weekend goes to keeping a server alive, this is the calm version: one prepaid wallet, hosted execution, and workflows that keep running while you do something else.

Every product on the LetBe.ai homepage started as a workflow in this builder. Yours could be next.
