Build customer-facing AI agents for support, sales, and product guidance
Write instructions in plain language, choose a model, set guardrails, and connect the knowledge the agent is allowed to use.
Let agents look up orders, fetch invoices, create tickets, or trigger workflows, and reply with interactive components instead of plain text.
Publish one agent to a website chat bubble, help center, phone line, WhatsApp, email, and Slack without rebuilding it per channel.
Humans and agents work from the same conversation view, with context and history preserved when an issue escalates.

Free, signup-free AI replies for LinkedIn, Twitter/X and Instagram using your own OpenAI key.
Open the extension icon in the comment interface on LinkedIn, Twitter/X or Instagram and it drafts a reply for that specific thread.
Paste your own GPT API key in the extension settings — no account, no proxy server, and no data collection per the developer's disclosure.
Write instructions to match your brand voice or personal persona so generated comments sound like you rather than a default chatbot.
Runs as a lightweight Chrome extension (about 24 KB) directly in the sites you already use, so there is nothing heavy to install or manage.
