Getting Started

Welcome to Lenno! This guide will walk you through creating your first AI agent in just a few minutes.

1. Sign Up

Head to the Lenno homepage and enter your email address to receive a magic link. Click the link in your inbox and you will be signed in immediately – no passwords to remember.

Once signed in, you will be asked to create or join an organization. Organizations are how teams share agents, billing, and settings.

2. Create Your First Agent

From the Agents page, click New Agent and fill in the basics:

  • Name – Give your agent a memorable identity (e.g., “Support Bot”, “Research Assistant”)
  • Personality – Describe how your agent should behave, its tone, expertise, and style. This is the single most important field – it shapes every response your agent generates.
  • Plan – Choose a plan tier (Starter, Builder, Pro, or Max) based on the compute resources and features you need.

Click Create and your agent is live.

3. Set Up an AI Provider

Lenno uses a Bring Your Own Key (BYOK) model. You connect your own API keys from AI providers like Anthropic, OpenAI, or Mistral. This means you keep full control over costs and usage.

To add a provider:

  1. Go to your agent’s Provider tab
  2. Select a provider (e.g., Anthropic Claude)
  3. Enter your API key
  4. Choose a model (e.g., claude-sonnet-4-20250514)
  5. Click Save

See the detailed Provider Setup Guides for step-by-step instructions per provider.

4. Connect a Channel

Channels are how users talk to your agent. The simplest to set up is Telegram:

  1. Open Telegram and message @BotFather
  2. Send /newbot and follow the prompts to create a bot
  3. Copy the bot token BotFather gives you
  4. In Lenno, go to your agent’s Channels tab
  5. Click Add Channel and select Telegram
  6. Paste the token and save

Your agent is now live on Telegram. Send it a message and watch it respond!

See Channel Setup Guides for Slack, Discord, email, and more.

5. Your First Conversation

Send a message to your agent through the channel you connected. The agent will:

  1. Receive the message through the channel
  2. Process it using your configured AI provider
  3. Apply any guardrails you have set
  4. Send a response back through the same channel

You can also chat with your agent directly in the Lenno web interface using the Chat tab.

  • Skills – Give your agent specialized abilities
  • Schedules – Set up recurring tasks with cron expressions
