Hiver vs Plain: at a glance
What is Hiver?
Gmail-based support tooling wiring internal docs into its AI and unifying search across channels
Hiver's April releases center on grounding its AI in a company's own material. Confluence pages, Google Docs and Google Sheets can be added as knowledge sources, and Ask AI can query an uploaded Sheet directly — answering questions like top customers by revenue without manual analysis. Alongside that, Omnichannel Search spans email, chat and Slack with unified results and channel attribution, and automations gained a trigger for conversations moved into a shared inbox. Each release appears twice in the feed.
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
Hiver's April releases center on grounding its AI in a company's own material. Confluence pages, Google Docs and Google Sheets can be added as knowledge sources, and Ask AI can query an uploaded Sheet directly — answering questions like top customers by revenue without manual analysis. Alongside that, Omnichannel Search spans email, chat and Slack with unified results and channel attribution, and automations gained a trigger for conversations moved into a shared inbox. Each release appears twice in the feed.
◆ Where it's heading
The product is extending past the shared-inbox job into being the place a support agent finds any answer. Knowledge sources make the AI useful on internal SOPs rather than generic replies; omnichannel search makes prior context findable regardless of where the conversation happened. Both reduce the reasons an agent leaves Gmail, which is the whole premise Hiver sells on.
◆ Prediction
Expect more knowledge source connectors on the pattern set by Drive and Confluence, since the Sheets query capability shows the ingestion path already handles structured as well as prose content.
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.
