AI-assisted gantt project planning that runs on your machine
Desktop project planner for Windows, macOS and Linux. Gantt with dependencies, resource utilisation, what-if scenarios, and an AI assistant that knows your plan. Runs on a local Ollama model by default. No account, no cloud, no subscription — €4.99 once.
Hey Product Hunt 👋 I'm Martin, a project manager who got fed up with keeping a Gantt in one tool, a capacity plan in Excel, and "what if we lose two people in March" in my head.
shadow-planner puts all of that in one desktop app:
Gantt chart with finish-to-start dependencies — drag a task and it previews every downstream shift before saving anything
Resource utilisation — weekly capacity vs. allocation per person, over-capacity highlighting, cost roll-up from daily rates
Scenarios — copy your baseline, test a re-org or a slipped deadline, compare, throw it away. Snapshots for the record.
An AI assistant that actually knows your plan — "who's over capacity next month?", "push the beta a week and show me what moves". Destructive changes wait for your approval.
Planning agent — paste a Markdown brief, get epics, tasks, dates and assignments as a draft you review Two things I care about most:
🔒 Your data stays yours. It's a local SQLite file — no account, no sync, no telemetry. The AI runs on a local Ollama model by default; Claude, OpenAI or OpenRouter are opt-in with your own key, called directly from your machine. 💸 No subscription. The free tier has every feature (capped at 1 scenario / 3 projects / 3 people). €4.99 once for unlimited — forever. I launched with a monthly plan, got told off, and switched; existing subscribers became lifetime for free.
