What is Thread?
Thread is turning its MSP helpdesk into a full Voice AI platform, now reaching outbound calls.
Thread is an AI helpdesk for MSPs built around a Triage Agent and Voice AI that answers and routes inbound calls into PSA tickets. Recent work pushes on three fronts: voice (transcription, custom farewells, speech controls), the Triage Agent (structured testable rules), and visibility (a six-dashboard analytics suite). The product sits tightly against partners' PSAs.
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.
Thread vs Plain: editorial side-by-side
Thread
6.3SUPPORT
Thread is turning its MSP helpdesk into a full Voice AI platform, now reaching outbound calls.
◆ Current state
Thread is an AI helpdesk for MSPs built around a Triage Agent and Voice AI that answers and routes inbound calls into PSA tickets. Recent work pushes on three fronts: voice (transcription, custom farewells, speech controls), the Triage Agent (structured testable rules), and visibility (a six-dashboard analytics suite). The product sits tightly against partners' PSAs.
◆ Where it's heading
Voice is becoming Thread's center of gravity. After building out inbound handling, custom agents, and transcript-to-PSA delivery, the latest releases add outbound calling and finer call controls - the product is becoming a full telephony layer for MSP service desks, not just an inbound attendant.
◆ Prediction
Expect deeper outbound workflows next - agent-initiated callbacks, dialer-style queues, and analytics that tie outbound call volume to the ROI dashboards Thread just shipped.
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.
