Desk365 vs Plain: at a glance
What is Desk365?
Desk365 ships steady ITSM upgrades — asset management and import APIs lead.
Desk365 is a Microsoft Teams-native helpdesk and ticketing tool. Its feed interleaves genuine bi-monthly product-update posts with a larger stream of support how-tos and SEO content. The recent real release (Phase 2, June 2026) focuses on asset and software management, a 24-hour time format, and two new ticket-import API endpoints.
What is Plain?
Plain is rebuilding customer support around autonomous agents Ari and Sidekick
Plain has moved from a support inbox into an AI-native platform anchored by two agents: Ari, which drafts and sends grounded replies, and Sidekick, an assistant that now takes actions across connected tools. Recent releases center almost entirely on expanding what these agents can do and where they run, with inbox mechanics playing a supporting role.

Desk365
5.0SUPPORT
Desk365 ships steady ITSM upgrades — asset management and import APIs lead.
◆ Current state
Desk365 is a Microsoft Teams-native helpdesk and ticketing tool. Its feed interleaves genuine bi-monthly product-update posts with a larger stream of support how-tos and SEO content. The recent real release (Phase 2, June 2026) focuses on asset and software management, a 24-hour time format, and two new ticket-import API endpoints.
◆ Where it's heading
Desk365 is broadening from pure ticketing toward fuller IT service management — asset/inventory tracking, multilingual agent portal, permissions, and API surface for integration. The cadence is incremental and predictable, aimed at deepening the Teams-centric ITSM footprint rather than making category-shifting moves.
◆ Prediction
Expect the next bi-monthly update to continue along asset management, automation, and integration-API lines. The product signal is reliable but modest; nothing in the feed points to a directional pivot.
Plain
6.3SUPPORT
Plain is rebuilding customer support around autonomous agents Ari and Sidekick
◆ Current state
Plain has moved from a support inbox into an AI-native platform anchored by two agents: Ari, which drafts and sends grounded replies, and Sidekick, an assistant that now takes actions across connected tools. Recent releases center almost entirely on expanding what these agents can do and where they run, with inbox mechanics playing a supporting role.
◆ Where it's heading
The arc is consistent: Plain is pushing its agents from suggestion toward action, and from the Plain UI outward into Slack and third-party tools. Each release widens the agent's authority (drafting to acting) and its surface (composer to Slack to connected tools).
◆ Prediction
Expect Sidekick's action-taking to deepen with more tools and more autonomous workflows, and Ari's autonomous handling to keep expanding, consistent with the steady cadence of agent-capability releases in these entries.
