The Software I Built That No One Uses (and Why It Matters)

There’s a term I keep coming back to lately: personal software.

Not startups. Not side hustles. Not products meant to impress anyone.

Just tiny tools you build for yourself.

Honestly, I’ve learned more from building these small, selfish tools than from any job or college class. And it’s not even close.

When you build personal software, there’s:

• no deadline pressure

• no stakeholder expectations

• no “is this scalable?” anxiety

There’s only one question: does this make my life slightly better?

That freedom changes how you learn.

What I Mean by Personal Software

When the AI wave was still new and confusing, I built ToneWise, a super simple app to fix grammar and adjust tone in messages.

No big vision. No growth plan.

I just wanted to write messages without overthinking every word.

While building it, I accidentally learned:

• how to work with early AI APIs

• prompt design before it was a buzzword

• and how small UX choices affect trust

• and learnt how to use nextjs

No course taught me that.

Later, when I wanted to actually understand databases (not just write SQL and move on), I built Fastbase, a lightweight database viewer.

Again, not to compete with existing tools. Just to see data clearly, my way.

That project taught me more about:

• schemas

• relationships

• performance tradeoffs

than any “DB fundamentals” tutorial ever did.

Also on frontend side I learnt

• how electron works whats renders, ipc etc

• using tanstack queries + router

And when I realized my tweets weren’t improving no matter how much advice I consumed, I built TwitLab, a playground just for writing better tweets.

No audience. No analytics obsession.

Just reps.

That’s when writing finally started clicking.

Why Personal Software Works So Well

Because it’s driven by real friction, not abstract goals.

You’re not learning for:

• a certificate

• a promotion

• or a resume bullet

You’re learning because something annoys you right now.

And that kind of learning sticks.

You remember the mistakes. You remember the tradeoffs. You remember why you made a decision.

Formal education rarely gives you that.

The Best Part

Most of these tools will never be used by anyone else.

And that’s the point.

Personal software isn’t about validation. It’s about clarity.

It ....

• sharpens your thinking.

• exposes gaps you didn’t know you had.

• quietly compounds your skills.

If you’re a developer, writer, or builder and feel stuck:

Don’t start a startup. Don’t chase trends.

Build a tiny tool that fixes something annoying in your life.

That’s where the real learning happens.
