DoneDone vs Plain
Side-by-side trajectory, velocity, and editorial themes.
DoneDone keeps polishing its Kanban boards and shared-inbox workflows.
DoneDone is a task-tracking and shared-inbox tool, and its recent releases concentrate on board and mailbox usability: collapsible Kanban columns, new sort options, a Mailbox Kanban view, active-assignee filtering, and quieter activity feeds with actions hidden by default. Each is a focused, incremental UX improvement.
The direction is workflow refinement rather than expansion — reducing noise, giving users more control over how boards and inboxes are organized, and bringing Kanban patterns to the shared mailbox. It's the steady polish of an established tool tightening its day-to-day experience.
Expect continued board and mailbox UX refinement — more view, sort, and filtering controls — rather than a new capability area.
Plain turns Sidekick from a drafting assistant into an agent that acts
Plain is a customer-support platform building an agentic layer — 'Sidekick' — into the core thread workflow. Recent releases moved Sidekick from suggesting to acting: it can take actions across connected tools, start working proactively the moment a thread matches a workflow, and it now answers in Slack. The surrounding plumbing (scheduled workflows, thread fields via the chat widget, machine-user API links to Linear) is all in service of more automation.
The arc points to autonomous, workflow-driven support: AI that investigates, summarizes, drafts, and executes before a human opens the thread. Each release widens either Sidekick's reach (Slack, connected tools) or the triggers that set it off (workflow conditions, schedules), steadily shifting the human role from doing the work to reviewing it.
Expect deeper Sidekick autonomy — more action types and likely approval or guardrail controls — plus more workflow triggers that launch automation without a human in the loop.
