Using the Letta Telegram Bot

Connect your Letta agents to Telegram for conversations anywhere

The Letta Telegram Bot (@letta_ai_bot) lets you chat with your Letta agents directly through Telegram, bringing persistent memory and intelligent conversations to your favorite messaging app.

Communications with Letta agents using the Telegram bot will modify the agent’s state everywhere that Letta agents are available — for example, you will see the Telegram messages appear in Letta’s ADE.

New Features:

  • Memory Management - View and inspect your agent’s memory blocks with /blocks and /block
  • Agent Templates - Quick-start with preconfigured agents using /template
  • Reasoning Control - Toggle agent thought visibility with /reasoning enable/disable
  • Proactive Notifications - Allow agents to send you messages with /telegram-notify
  • Enhanced Navigation - Comprehensive help system and quick reference commands

Getting Started

Step 1: Find the Bot

Open Telegram and search for @letta_ai_bot or visit t.me/letta_ai_bot directly.

Step 2: Start Your First Conversation

Send /start to the bot. You’ll receive an interactive welcome with buttons to guide you through setup.

Step 3: Connect Your Letta Account

You’ll need a Letta API key to use the bot:

  1. Get Your API Key:

    • Go to app.letta.com
    • Sign in or create a free account
    • Navigate to Settings → API Keys
    • Create a new API key and copy it

  2. Login to the Bot:

    /login sk-your-api-key-here

    The bot will immediately delete your message for security and confirm successful authentication.

Step 4: Select an Agent

View your available agents:

/agents

Select an agent to chat with:

/agent agent-id-here

Step 5: Start Chatting

Once you’ve selected an agent, just send any message to start your conversation.

  1. Verify your API key at app.letta.com
  2. Make sure you’re copying the entire key
  3. Try generating a new API key
  4. Use /logout first if you’re having issues

Agent Not Working

If your agent isn’t responding properly:

  1. Check that an agent is selected with /agent
  2. Verify the agent exists with /agents
  3. Try switching to another agent and back
  4. Visit the ADE with /ade to check agent status

Message Errors

Practical Examples and Edge Cases

Setting Up Multiple Agents for Different Purposes

Scenario: You want different agents for work and personal use.

# First, create shortcuts for easy switching
/shortcut work agent-abc123
/shortcut personal agent-xyz789
# During work hours
/switch work
"Can you review the quarterly report I mentioned yesterday?"
# After work
/switch personal
"What ingredients did we decide on for the dinner party?"

Handling Authentication Issues

Edge Case: Your API key expires or becomes invalid.

You: Hello, are you there?
Bot: Authentication error
Your stored credentials appear to be invalid.
Please try /logout then /login <new_api_key>
# Solution:
/logout
/login sk-new-api-key-here

Managing Tools for Specific Tasks

Scenario: You need web search for a research project.

# Check current tools interactively
/tool
# Select "attach new tools" button
# Navigate to web_search and select it
# Or use direct command:
/tool attach web_search
You: What are the latest developments in quantum computing?
Agent: Let me search for recent information... [uses web_search tool]

Working with Large Agent Lists

Edge Case: You have many agents and can’t remember IDs.

# Use shortcuts for frequently used agents
/shortcut main agent-abc123def456
# Search projects if agents are organized by project
/projects research
/project project-research-001
/agents
# Use descriptive shortcut names
/shortcut research-quantum agent-qnt789
/shortcut research-climate agent-clm456

Recovering from Errors

Scenario: Bot stops responding mid-conversation.

# First, check your status
/status
# If authenticated, check agent selection
/agent
# If no agent selected, reselect
/agents
/agent agent-abc123
# If issues persist, refresh credentials
/logout
/login sk-your-api-key

Switching Context Quickly

Scenario: Multiple ongoing projects with different agents.

# Morning standup prep
/switch work
"Summarize yesterday's progress on the API integration"
# Client meeting
/switch client-project
"What were the three main concerns from our last meeting?"
# Personal reminder
/switch personal
"What time did I say I'd pick up the kids?"

Tool Conflicts and Resolution

Edge Case: Multiple tools with similar names.

/tool attach search
Bot: (ambiguous tool name)
multiple tools match 'search':
• web_search - search the internet
• doc_search - search documents
• code_search - search codebases
try being more specific
# Solution:
/tool attach web_search

Memory Continuity Across Sessions

Example: Continuing a complex discussion.

# Monday
You: Let's plan the product launch for next month
Agent: I'll help you plan the launch. Let's start with...
# Wednesday
You: Where did we leave off with the launch plan?
Agent: On Monday, we outlined the timeline and identified three key milestones...

Handling Network Issues

Edge Case: Slow or interrupted connections.

You: [Sends message]
[No response for 30 seconds]
# Bot will show typing indicator if processing
# If timeout occurs:
Bot: (please wait)
that took longer than expected. the query might be complex - try breaking it into smaller parts

Project and Agent Coordination

Scenario: Organizing agents across multiple projects.

# View all projects
/projects
# Switch to development project
/project project-dev-123
# See dev-specific agents
/agents
# Create shortcuts for cross-project access
/shortcut dev-backend agent-backend-456
/shortcut dev-frontend agent-frontend-789
