Sellio

About Sellio

Sellio is a shared inbox for customer support that brings live chat, WhatsApp, Instagram, Telegram, and email into one place. It includes AI agents that can be trained on a team's own documentation to answer questions automatically. The tool also provides a customizable chat widget, a help center, and built-in analytics.

Review

Sellio launched this week, targeting small support teams of 2 to 20 people. The maker describes it as a straightforward alternative to larger suites, with a focus on predictable costs and quick setup. This review is based on the information available at launch.

Key Features

• Shared inbox with multiple channels. Website chat, WhatsApp, Instagram, Telegram, and email all feed into a single workspace. These channels are included from the first paid plan.
• Trainable AI agents. AI agents answer customer questions based on a team's uploaded knowledge base. Daily and monthly credit limits can be set to control usage and avoid unexpected charges.
• Customizable chat widget. A chat widget can be added to a website with one script tag. Human agents can take over conversations from the AI at any point.
• Built-in analytics and help center. The platform tracks support metrics and hosts a public-facing help center for customers.

Pricing and Value

Sellio uses per-workspace pricing, not per-agent pricing. A free plan is available with no credit card required. The first paid plan costs $45 per month for the entire workspace. AI agent usage runs on an included credit system with configurable daily and monthly limits - this is the mechanism the maker highlights to prevent surprise bills. For comparison, the maker notes that five agents on a competing suite's team plan would cost roughly $275 per month, with additional charges for each AI resolution.

Pros

• Single workspace price instead of per-seat charges keeps costs predictable for small teams.
• AI credit limits are set by the user, which gives direct control over spending.
• Multiple messaging channels are included in the first paid tier rather than sold as add-ons.
• Setup is described as adding a script tag and connecting channels - no implementation project needed.
• A free plan exists for teams that want to test the tool before committing.

Cons

• When the daily AI credit limit is reached, the handoff to human agents depends on someone monitoring the queue in real time. A mid-conversation customer might not see an immediate notification that a human will reply later.
• The tool is not well suited for teams that need a phone contact center or enterprise compliance requirements such as HIPAA, as the maker acknowledges these are outside its scope.
• As a product launched this week, it lacks a track record of handling sustained support volume over time, and community discussion about long-term reliability is still open.

Sellio fits small support teams that want multiple messaging channels in one inbox and need to cap AI costs with hard limits. It's less appropriate for organizations with complex compliance needs or those requiring immediate, guaranteed human fallback when AI credits run out. Teams considering it can start with the free plan to see how the inbox and AI agent behave with their own documentation.
