Plain vs INKY
A side-by-side editorial comparison of Plain and INKY — release velocity, themes, recent moves, and the top alternatives to consider.
Plain vs INKY: at a glance
What is Plain?
Sidekick got skills and MCP; now Plain is clearing the path to move your history in.
Plain's recent releases built Sidekick from an in-thread helper into an operator that uses workspace skills and connects to any MCP server, with workflows becoming the trigger layer for that agent work. The newest entry moves to the other end of the funnel: custom importers pull past conversations in from any tool, including in-house systems, with no built-in importer required.
What is INKY?
INKY is wiring an LLM into email security while binding itself tighter to Kaseya.
INKY ships a dashboard release every one to two weeks, moving from 1.8.5 to 1.9.5 since May. The functional center is the Triage workspace, which pulled detection review, message actions and account-takeover enforcement into one place and made ATO configurable without a SIEM. July added Smart Insights, an LLM second opinion on inbound mail, plus automatic Autotask ticketing. Running alongside the security work, email-signature management has grown from a single page in June into a tabbed editor with per-field styling.
Plain vs INKY: editorial side-by-side
Plain
7.5SUPPORT
Sidekick got skills and MCP; now Plain is clearing the path to move your history in.
◆ Current state
Plain's recent releases built Sidekick from an in-thread helper into an operator that uses workspace skills and connects to any MCP server, with workflows becoming the trigger layer for that agent work. The newest entry moves to the other end of the funnel: custom importers pull past conversations in from any tool, including in-house systems, with no built-in importer required.
◆ Where it's heading
Capability, then autonomy, then extensibility, and now onboarding. Removing the importer dependency means adoption stops being capped by Plain's connector roadmap, the same way the agent's ceiling stopped being its integration roadmap. The pattern across both is Plain declining to sit as the bottleneck between a customer's existing systems and its own product.
◆ Prediction
Expect the importer work to be followed by tooling that puts migrated history to use - Sidekick reading imported conversations for context is the obvious next step given the skills and MCP groundwork already shipped.
INKY
6.3SUPPORT
INKY is wiring an LLM into email security while binding itself tighter to Kaseya.
◆ Current state
INKY ships a dashboard release every one to two weeks, moving from 1.8.5 to 1.9.5 since May. The functional center is the Triage workspace, which pulled detection review, message actions and account-takeover enforcement into one place and made ATO configurable without a SIEM. July added Smart Insights, an LLM second opinion on inbound mail, plus automatic Autotask ticketing. Running alongside the security work, email-signature management has grown from a single page in June into a tabbed editor with per-field styling.
◆ Where it's heading
Two threads are pulling in the same direction. Detection is becoming AI-assisted and explainable, with Smart Insights returning a verdict, a trickiness rating and a written rationale rather than a score. And the managed-service channel is being deepened at every layer — Autotask billing, Autotask ticketing, Kaseya-provisioned entitlements, a third-party training platform slotted in as an option. INKY is optimizing for the provider reselling it across many tenants, not the employee reading the mail.
◆ Prediction
Smart Insights is gated to Pro with a per-team opt-out, which points to it being extended and monetized further rather than made universal. Mesh was added as a recognized upstream provider under an auto-detect setting, so additional relay providers are the obvious continuation of that work.
