INKY vs Sleekplan
A side-by-side editorial comparison of INKY and Sleekplan — release velocity, themes, recent moves, and the top alternatives to consider.
INKY vs Sleekplan: at a glance
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.
What is Sleekplan?
Sleekplan rebuilt itself around an AI layer that triages feedback instead of filing it.
Sleekplan spent 2026 on a rebuild rather than incremental releases. Sleekplan 2.0 entered beta in June with a rewritten admin app and an AI layer over the feedback loop; the Impact Score was rebuilt the same day to be inspectable and configurable rather than an opaque number. The Chrome extension has now been rebuilt to match, letting a team member search the board, add votes and post on a customer's behalf from wherever the feedback lands.

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.
Sleekplan
2.5SUPPORT
Sleekplan rebuilt itself around an AI layer that triages feedback instead of filing it.
◆ Current state
Sleekplan spent 2026 on a rebuild rather than incremental releases. Sleekplan 2.0 entered beta in June with a rewritten admin app and an AI layer over the feedback loop; the Impact Score was rebuilt the same day to be inspectable and configurable rather than an opaque number. The Chrome extension has now been rebuilt to match, letting a team member search the board, add votes and post on a customer's behalf from wherever the feedback lands.
◆ Where it's heading
The pattern is capture-everywhere plus decide-automatically. Pulling feedback in from support inboxes, CRMs and call notes is one half; making prioritization explainable enough to run unattended is the other. Cadence is low and lumpy — a Linear integration in February, then nothing until the 2.0 beta — so the rebuild is consuming the roadmap.
◆ Prediction
The next release most likely moves 2.0 out of beta. The configurable Impact Score formula is the piece to watch, since it has to be trusted before the AI layer can prioritize without review.
