LiveAgent vs Plain: at a glance
What is LiveAgent?
LiveAgent's 5.70 branch adds Mistral and Gemini, live call transcription and message translation.
LiveAgent's 5.70 branch arrived with a large feature batch: Mistral AI as an EU-hosted provider, Gemini and OpenAI for ticket summaries and translation, live call transcription with speaker attribution, and on-demand translation of inbound messages. It also adds a Deskpro migration plugin and plan limits on event, time and SLA rules. The releases since are fix-only, mostly around chat widget errors and API gaps.
What is Plain?
Plain built an autonomous support agent, and has now built the controls to trust it.
Plain's changelog is dated entries with no titles, and nearly all of it concerns two AI surfaces: Ari, the customer-facing responder, and Sidekick, the internal agent. Sidekick spent July gaining reach — its own full-page home, reusable workspace skills, and connection to arbitrary MCP servers. The newest release turns to Ari and adds what was missing around it: a way to test it before customers see it, provenance behind each answer, configurable tone, and explicit escalation rules.

◆ Current state
LiveAgent's 5.70 branch arrived with a large feature batch: Mistral AI as an EU-hosted provider, Gemini and OpenAI for ticket summaries and translation, live call transcription with speaker attribution, and on-demand translation of inbound messages. It also adds a Deskpro migration plugin and plan limits on event, time and SLA rules. The releases since are fix-only, mostly around chat widget errors and API gaps.
◆ Where it's heading
The AI layer is turning multi-provider: OpenAI, Anthropic, Gemini and Mistral now sit side by side, with retired OpenAI models migrated automatically. Voice and translation are where that layer is being applied first. The paired 5.69 and 5.70 releases on the same day show two branches being maintained in parallel.
◆ Prediction
Expect message translation to move past its 'Stage 1' on-demand scope, likely toward outbound or automatic translation. Further 5.69/5.70 fix pairs are likely in the meantime.
Plain
8.8SUPPORT
Plain built an autonomous support agent, and has now built the controls to trust it.
◆ Current state
Plain's changelog is dated entries with no titles, and nearly all of it concerns two AI surfaces: Ari, the customer-facing responder, and Sidekick, the internal agent. Sidekick spent July gaining reach — its own full-page home, reusable workspace skills, and connection to arbitrary MCP servers. The newest release turns to Ari and adds what was missing around it: a way to test it before customers see it, provenance behind each answer, configurable tone, and explicit escalation rules.
◆ Where it's heading
The sequence reads as capability first, then governance. Plain rebuilt Ari into an agentic first responder, opened Sidekick to any MCP server, and let teams write skills the whole workspace shares — all of which widen what the agents can do and reach. The current release closes the loop the other way, making that autonomy inspectable and bounded before it is switched on. That is the order support-AI vendors have to complete in: teams will not put an agent in front of customers on capability claims alone.
◆ Prediction
With testing and provenance in place, the next step is likely measurement — resolution and escalation rates per skill, or per-answer quality review feeding back into the skills teams write. The entries are short summaries linking off-site, so per-release depth is limited.
