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.

One-click ChatGPT replies for Twitter and X posts
Select any tweet, open Replizen and get a written reply in a single click instead of starting from a blank box.
Choose from more than 500 style, tone and length combinations to match the voice you want to project.
Replies are tailored to the specific post you have selected, so the response stays on topic.
Generate the reply, then tweak the wording before posting so it still sounds like you.
