Hello! I'm Athen, your universal AI agent. I can execute shell commands, read and write files, manage tasks, and more.
Type a message below to get started.

Universal AI Agent
Arc Timeline
Settings
LLM Providers
Configure the AI models Athen uses. Changes take effect after restarting the app.
Memory & Embeddings
Configure how Athen processes and remembers information.
Auto-detects the best available provider for generating embeddings.
Agent Profiles
Specialists that handle different kinds of work. Built-ins ship with Athen and can be cloned to customize. Your own profiles can be edited or deleted freely.
Identity
Who Athen is across every agent — personality, rules, knowledge about you, team. Each entry can be scoped to specific profiles so the coder doesn't pay tokens for personality content it never uses. Long identity blocks crowd out task context on smaller models.
0 tokens (~0%)
Pick a category to see its entries.
Tools (MCP)
Toggle which Model Context Protocol servers Athen can use. Enabled tools become available to the agent on the next turn — no restart needed.
MCP Servers
Connect tools from Slack, Notion, GitHub, and more by adding a Model Context Protocol server. Each one runs as a sandboxed subprocess on your machine. Where do MCP servers come from?
No MCP servers yet. Click + Add Server below to wire up npx, uvx, or any local stdio MCP binary.
Shell Toolbox
Persistent Python and Node packages the agent installed for itself under ~/.athen/toolbox. PYTHONPATH and PATH are auto-injected into every shell command, so anything listed here is importable/runnable without further configuration. The agent asks for permission before installing.
My Contact Info
Athen uses this to recognize when a message is from you (auto-trust) and to skip approval when sending to your own address. Athen's own credentials (IMAP, SMTP, Telegram bot) cannot overlap with these.
Email Monitor
Connect your email to let Athen monitor and act on incoming messages.
Most providers need an app-specific password, not your regular login password.
Same app password works for both IMAP and SMTP on most providers.
What recipients see. Plain "alex@example.com" or "Alex <alex@example.com>" both work.
Comma-separated list of IMAP folders.
Only process emails newer than this.
Advanced (server settings)
Incoming (IMAP)
Outgoing (SMTP)
587 for STARTTLS (default), 465 for implicit TLS.
Usually the same as your email address.
Leave unchecked for STARTTLS on port 587.
Telegram Bot
Create a bot via @BotFather on Telegram, then paste the token here.
Only process messages from these chats. Leave empty to accept all.
Web Search
Athen uses Brave first, falls back to Tavily, and only drops to keyless DuckDuckGo when both are exhausted. Either or both keys are optional — leave them blank to rely on the DDG fallback.
2,000 free queries/month. Sign up at api.search.brave.com.
~1,000 free queries/month, answer-ready snippets. Sign up at tavily.com.
Cloud APIs
Register cloud HTTP endpoints (Hunter, Brave Search, Open-Meteo, …) the agent can call via the generic http_request tool. Pick a preset, paste your key, and click Save — the credential goes straight into the encrypted vault, never into config.toml. Bespoke tools (web_fetch, email_send, calendar) take precedence when one already exists for a given API.
No endpoints registered yet.
Attachments
Controls how Athen handles attachments arriving via email, Telegram, or the chat composer. Defaults are safe for most users — tighten the trust gates if you receive a lot of mail from strangers.
Anything not in a checked category is dropped on arrival. Executables and archives are blocked by being absent.
Combined cap across all attachments on a single email/Telegram message.
Below this, the file is skipped entirely — no metadata, no bytes.
Below this, bytes are saved but not pushed to the agent's first turn — agent has to opt in by tool call.
Original bytes are purged after this many days. Extracted text sidecars stay forever (small, useful for arc continuity).
Notifications
Configure how Athen contacts you for important events and approvals.
Order in which channels are tried. First channel is preferred.
Wait this long before trying the next channel when no response.

Security
Standard risk evaluation. The agent asks for approval on risky actions.
