Lately, I’ve been thinking about the apps I use every day.
- Mail.
- Notes.
- Reminders.
- Tasks.
- Calendar.
- Project management.
- Invoices.
- Password manager.
- Chat.
Most of these tools are either owned by big tech companies, locked inside ecosystems, or separated across multiple apps that don’t really understand each other.
And honestly, I don’t like depending too much on Google, Microsoft, Notion, or any single platform for my day-to-day work.
So I’ve been thinking about building my own.
Not another productivity app.
More like a personal operating system running on the web, where daily tools are connected and AI can understand the context across them.
The idea
I want to start with something simple:
- Notes
- Tasks
- Reminders
- AI assistant
The first version would be for myself.
A place where I can write notes, turn them into tasks, create reminders, connect ideas to projects, and let AI help me organize everything.
Later, it could grow into:
- project management
- invoice generator
- calendar
- password manager
- chat
- maybe more daily tools
The main idea is that these tools should not live separately.
For example:
- A note can become a task.
- A task can become a reminder.
- A project can generate an invoice.
- AI can summarize related notes, tasks, and calendar items.
- Chat can become a command center for the whole system.
Instead of jumping between 10 apps, the system could understand the work as one connected flow.
Why I want to build this
For me, this is not only about productivity.
It is also about:
- privacy
- data ownership
- avoiding vendor lock-in
- reducing dependency on big tech apps
- keeping important work in a system I control
- creating tools that match my own workflow
Most apps are powerful, but they are built for everyone.
I want to build something that starts with my workflow first.
If it becomes useful for other developers, freelancers, or small startup teams, then it could be shared later.
Open source, closed source, or open-core?
This is one area I am still thinking about.
Fully open source sounds good because the community can trust it, contribute to it, and run it themselves.
Closed source gives more control if it becomes a serious product.
But right now, I feel open-core may be the best direction.
The core productivity system could be open source.
Then advanced hosted features, AI integrations, team features, cloud sync, or business tools could become paid features later.
That feels like a fair balance between community and sustainability.
Build in public?
I am also thinking about building this in public.
Not as a perfect product launch.
More like sharing:
- architecture decisions
- database design
- UI decisions
- AI feature experiments
- privacy and security challenges
- what works and what fails
- how the system evolves from personal use to something others may use
I think this could be interesting because building a connected personal productivity system is not just a coding problem.
It includes product thinking, security, AI context design, data ownership, sync, UX, and long-term maintainability.
Some questions for the community
I would love to hear thoughts from other developers and builders.
Would you use something like this?
Should this kind of project be open source, closed source, or open-core?
Should I build one app first, like notes + tasks + reminders, or design it as one connected ecosystem from the beginning?
Which module would you start with?
Would a build-in-public journey for this be interesting to follow?
What risks should I think about early?
And most importantly:
How would you handle privacy, sync, AI, and security for something like this?
I am still in the idea stage, but I feel this could become an interesting long-term project.
Maybe it becomes just my personal tool.
Maybe it becomes an open-source project.
Maybe it becomes an AI-first web OS for developers, freelancers, and small teams.
Either way, I think it is worth exploring.
