Built an AI Shareable Task and Event Manager | OSS | Self-Host it

Heyooo

Pretty excited to share my open-source project: ⚡ DerPlanner - The Shareable Task Event Planner.

Live Demo : derplanner.space

At its core, it’s a full-stack app where you manage tasks and events just by having a conversation.

Instead of clicking around, you just type:

• "Create a task to finish the report by Friday, make it high priority."
• "Schedule a meeting with the team tomorrow at 2 PM about the launch."
• "Research the latest trends in generative AI for 2025."

The AI agent figures it out, creates the task or event, and even uses deep research models (like OpenAI's o3/o4) to give you citation-backed answers.

But here's the real magic: Automation 🤖

The biggest problem with most planners is that your data is "stuck." When I complete a task, I almost always have to do something else.

• Check off "Follow up with lead X" → Now I have to go to my CRM and update it.
• An event "Product Launch" starts → Now I have to go send the marketing email.

I built DerPlanner with Webhooks for exactly this. When a task is completed or an event starts, it can fire off an HTTP request to any service you want.

This is where it gets fun for devs. You can hook it up to n8n, Zapier, or your own custom endpoint.

For example, I built a workflow to automate my marketing. When a task is completed, it triggers an n8n workflow that can send an email, update a CRM, and send an SMS, all automatically.

This is a fantastic project — thanks for sharing it! The concept of a conversational task/event manager (you type “Schedule a meeting with the team tomorrow at 2 PM …” and it handles everything) really hits a sweet spot between simplicity and power. The addition of webhooks so tasks/events can trigger automation workflows (CRM updates, emails, SMS, etc) is especially compelling — it turns the planner into an automation hub, not just a list of things to do.

A few questions/suggestions:

• What AI model are you relying on for the “conversation → task/event” parsing? How accurate is it with more complex or ambiguous commands?
• Is the system designed for collaboration (multiple users sharing/assigning, permissions, etc)? That could make it very useful for small teams.
• For the self-hosted OSS angle: what are the required dependencies, and how easy is it to deploy and maintain (updates, backups, scaling)?
• One feature idea: allow recurring/open-ended tasks (“Research generative-AI trends each Monday”) and smart reminders based on progress/completion rate.

Overall, love the direction — especially for dev-savvy users who want more control (and privacy) than off-the-shelf SaaS planners. Looking forward to seeing how the project evolves!
