Plenar
Continuous project planning for the agentic age.
Work changes faster than plans can be updated. Plenar recomputes your plan, so you don’t have to. Assignments, timeline, and cost — computed from your constraints, and updated as scope or availability shift.
Why Plenar exists
Planning is a constraint satisfaction problem. Dependencies, skills, availability, priorities, deadlines — these interact combinatorially. A team of 5 people with 30 tasks and a handful of constraints already has millions of possible arrangements. Humans can’t explore that space. They pick a plausible-looking plan and stop.
When something changes — a new task, a revised estimate, a week of PTO — the plan should recompute. But in practice, nobody does. The schedule drifts, and by the time anyone notices, deadlines are already missed.
Plenar solves this. Every change triggers a recompute. You see exactly how the plan shifts, before you commit to it.
What makes Plenar different
Optimal assignments. Work assigned by skill, capacity, and priority to meet your deadline. Plenar respects dependencies, skills, availability, and priorities simultaneously — not sequentially. It finds the best arrangement given your constraints, not a rough approximation.
Change impact preview. Every change produces a diff showing exactly which tasks move, which goals slip, and which deadlines are still safe — before anything is saved. No surprises.
Agentic planning interface. Intent becomes structured work plans. Tell your agent what needs to get done — tasks, dependencies, skills, and estimates are structured automatically. A constraint solver optimizes assignments, timeline, and cost.
Execution intelligence. Signals from agents, Git, and CI/CD feed back into the schedule. Estimates calibrate over time. Plenar connects to Claude Code via MCP — manage your entire project plan from your coding environment.
Deadline feasibility. Know whether your goal ships before you commit to it. Plenar tells you the truth about when things will be done, given current constraints and capacity.
Get started
Pick the path that matches where you are:
-
First Schedule — Go from sign-up to a plan in 5 minutes. Best if you are new to Plenar. Or explore the sample project that comes with every new organization.
-
Connect Claude Code — Connect Plenar to Claude Code and manage your plan from the terminal. Best if you already have a project set up and want the agentic workflow.
-
How Scheduling Works — Understand how Plenar makes scheduling decisions and what “optimal” actually means. Best if you want to understand the computation.
