Onplana connects ChatGPT to your project portfolio. Describe the work in a sentence and it builds the project for you: epics, tasks, estimates, dependencies and scheduled dates, in a single step. Search across projects, tasks, sprints, risks, comments, and wiki with hybrid BM25 + vector search. Read project state, update tasks, log time, surface portfolio-level insights, and generate status reports, all gated by your org's plan and role permissions, with every operation audited. Built for teams migrating from Microsoft Project Online ahead of its September 2026 retirement.

Skills 2
- onplana-project-planner
Turn a goal or a brief into an executable Onplana plan over its MCP server: write a plan.md and attach it to the project, decompose it into tasks and subtasks, set start/due dates and dependencies, assign owners, add test cases as you go, and create tasks for the downstream surfaces a change ripples to. Use this whenever an agent (Claude Code, ChatGPT / Codex, or claude.ai) is connected to the Onplana MCP server and is asked to PLAN a project rather than just execute one. Hand the result to the onplana-autonomous-agent skill to run.
- onplana-autonomous-agent
Work autonomously on projects in Onplana over its MCP server: pick up the open tasks in a project, do the work, keep each task's status current, report progress as comments, file an Issue when something is wrong, and poll for human replies. Use this whenever an agent (Claude Code, ChatGPT / Codex, or claude.ai) is connected to the Onplana MCP server and is asked to run through a project's tasks on its own.
