Will one member see another member’s conversation?

No. Sessions are isolated per channel and chat ID, and personal memory is partitioned per chatter.

What stops people from abusing tools?

Guests never get host access. Set FASTCLAW_SANDBOX_ENFORCE=1 so every exec and file call runs inside a Docker or E2B sandbox — recommended when a bot faces the public.

Does LINE need anything special?

LINE delivers messages by webhook, so FastClaw needs a public HTTPS address, and you must provide the channel secret so every event is signature-checked.

Use case · Communities

AI chatbot for Telegram, Discord and LINE communities

Run an AI agent for your community on Telegram, Discord or LINE. Every member gets their own session, and untrusted chatters stay inside a sandbox.

Answers in groups and DMs

The bot replies when mentioned in group chats and holds private conversations in DMs, each with its own history.

Safe with strangers

Only the paired owner gets host access. Every other member is a guest whose commands run in the sandbox — or are refused without one.

One personality everywhere

Write the bot’s voice once in SOUL.md. The same agent can serve your Telegram group and Discord server at the same time.

Images and files

Members can send images and files; the agent can reply with images and file links where the platform supports them.

Any model behind it

Pick a fast, inexpensive model for busy groups, or route through OpenRouter to try several without changing the bot.

A bot that is more than a FAQ macro

A FastClaw agent can search the web, read pages, run code and remember context, so it can actually help members instead of pasting canned answers. Connect it to Telegram, Discord or LINE from the agent's channels page.

Open to everyone, locked down by default

Public bots meet untrusted input. FastClaw separates the bot's owner from everyone else: after you claim the bot with /pair <code>, every other member is a guest. Turn on the sandbox enforcement and all tool calls run in an isolated container instead of on your server.

Shape its character

The agent's tone, rules and boundaries live in plain Markdown files — SOUL.md and IDENTITY.md — that you edit in the dashboard. Learn more about how agents are built, or try the free SOUL.md generator under tools.
