Portal by LetBe.ai
Build an AI agent with no code
Pick ready blocks, tell the agent what it should do, teach it your documents, and talk to it while you build. When it answers the way you want, publish it. From that moment it runs hosted, and there is nothing for you to install or maintain.
Free to start. No card needed.
What is a no code AI agent?
An AI agent is software that takes a job and handles it in conversation: it reads the question, looks things up, decides what to say, and answers. A no code AI agent is one you build without writing any code.
In the LetBe.ai portal an agent is called a scenario. A scenario is a flow of blocks you arrange on a canvas. Each block does one job. One block holds the agent's instructions. One calls the AI model. One asks the user a question and waits for the answer. One searches the documents you uploaded so the agent answers from your content, not from guesses. One keeps the conversation safe and on topic. You connect the blocks, and the agent follows the path you drew. If you would rather describe the agent in a sentence and let the builder assemble the first version for you, it can do that too, and you refine from there.
A real agent, block by block
Here is the agent most businesses build first: one that answers customers from the company's own pages and documents. This is not an invented demo. The same pattern powers Chat by LetBe.ai, which answers real visitors on real business sites today.
- A User Input block receives the visitor's question and waits when the agent needs more detail.
- A document search block finds the passages of your uploaded pages and files that actually answer the question.
- A Prompt block holds the instructions: who the agent is, how it should sound, and what it must never do.
- An AI Model block writes the answer from those passages. You choose the model in the builder. There are no accounts to open and no keys to paste.
- A Guardrail block checks the reply so the agent stays polite and on topic.
You talk to the agent in a chat console the whole time you are building. When a step answers badly, you fix that block, not the whole thing. See how the builder works.
Nothing to install, nothing to host

The models are already here. No provider accounts, no keys to paste, no quota dashboards to babysit.
Nothing to host
Your agent runs in our cloud from the first click. Publish it and call it from your site, your code, or your tools, or share it as a chat.
No surprise bills
A prepaid wallet you top up when you choose. Nothing charges behind your back, and the pricing page has the detail.
How this compares to an ai workflow automation tool
Most workflow automation platforms connect your apps to each other, and the well known ones do that well. The portal is a different shape of tool. It is the AI side itself: an ai agent builder where the agent can pause in the middle of a run, ask the user something, and continue, and where the finished agent becomes a live address your website or software can call. You do not bring your own model accounts, rent a server, or keep anything alive. If your job is moving records between apps on a schedule, a workflow automation tool is the right pick. If your job is an agent that talks, decides, and answers from your own content, build it here. The documentation covers how published agents are called.
No code AI agent questions
What is a no code AI agent?
It is an AI helper you build by arranging ready made blocks instead of writing code. In the LetBe.ai portal you connect blocks for instructions, models, questions, and your own documents, and the result is an agent you can talk to and publish.
What should a no code ai agent platform include?
Four things: blocks you can understand at a glance, a way to test the agent while you build it, hosting so the agent runs without your own servers, and a way to connect the finished agent to your site or software. The portal includes all four, with the models built in.
Is this an ai agent builder or an ai workflow automation tool?
It is an ai agent builder first. Scenarios can branch, loop, and call outside services, so plenty of automation fits inside an agent. But the center of the product is an agent that converses and decides, not a pipe between two apps.
What does it cost to run an agent?
You start free, with no card. After that, a prepaid wallet pays for what your agent actually processes, and you top it up only when you choose. Current numbers live on the pricing page.
