About

Open is a unified AI customer support platform built around Agent 5, a single AI engine shared across every channel and designed to automate and unify support. It brings AI Chat, AI Calls, AI Email, AI Social, Agentic Workflows, and helpdesk integrations into one system so customer conversations can be handled consistently across web chat, phone, email, Instagram, Messenger, WhatsApp, SMS, and existing support tools. Agent 5 goes beyond simple FAQs by handling complex requests, processing returns, updating accounts, coordinating multi-step workflows, routing issues, remembering conversation history, and handing off smoothly to human agents when needed. Web Chat can be embedded with one line of code, customized to match the brand, triggered proactively based on user behavior, and enriched with images, videos, files, links, buttons, forms, cards, and carousels.

About

Sellio is a cloud-based customer support platform for small teams managing conversations across websites and messaging channels. It combines an embeddable live-chat widget with a shared inbox for website chat, email, WhatsApp, Instagram, Facebook Messenger, Telegram, and SMS through Twilio; teams can also handle conversations from Slack and Discord. Staff can assign conversations, add internal notes, view customer histories, and coordinate replies. AI agents answer website-chat questions using a business's own content and can hand conversations to a person; AI replies are limited to website chat, while other channels are handled by people. Sellio also includes ticket management, routing rules, workflow automation, saved replies, customer profiles, feedback tools, and support analytics. It is designed for SaaS businesses, online shops, and other small teams that support customers. A free plan is available, while paid plans add seats, channels, automation, and AI allowances.
