What is Sellio?
AI customer support in one shared inbox
Sellio is AI customer support in one shared inbox, built for small support teams (2–20 people) at stores, hotels, SaaS companies, local teams, and agencies. Website chat, WhatsApp, Instagram, Telegram, and email all land in one inbox with shared assignment, notes, tickets, and analytics — and Slack, Discord, and Teams can mirror new conversations for your team.
An AI agent answers from your website, help articles, FAQs, and documents only, so replies match what you actually ship — at about $0.05 per AI conversation, with daily and monthly caps you set. A person can take over any thread at any time, or the agent hands off automatically when its confidence drops, a visitor asks for a person, or a keyword you set appears.
Setup is one 18 KB async script tag — live in minutes on plain HTML, Next.js, React, Vue, Nuxt, Svelte, Astro, WordPress, Shopify, Squarespace, or Wix. Website chat and the shared inbox are free forever with no credit card; paid plans (Mini $36/mo, Essentials $76/mo, Plus $236/mo billed yearly) add channels, seats, AI agents, and AI credits, each with a 7-day trial.

Common questions
Sellio FAQs
Is Sellio really free?
Yes. Website chat and the shared inbox are free with no trial clock and no credit card. You only upgrade for more seats, channels, AI agents, and AI credits.
What does the AI agent cost?
About $0.05 per AI conversation, charged only when the agent replies to a visitor. Paid plans include a monthly AI allowance, and you set daily answer and monthly token caps.
Do I need a developer to install it?
No. It's one script tag before the closing body tag, with guides for plain HTML, Next.js, React, Vue, Nuxt, Svelte, Astro, WordPress, Shopify, Squarespace, and Wix.
Which channels are supported?
Website chat, WhatsApp, Instagram, Telegram, and email land in the same inbox. Slack, Discord, and Microsoft Teams can mirror new conversations to a channel your team watches.
Can a person take over from the AI?
At any time. Take control in the inbox and the AI stops answering that thread; it also hands off automatically when confidence drops, a visitor asks for a person, or a keyword you set appears.
