About

We built the assistant we wanted.
It lives in your favorite inbox.

PlsFixAI is a one-person studio making AI workers that reply to emails and fix attached files. No new app. No new login. You forward, it replies.

Why email

Chat apps wanted to replace email. Email won. It's still where the actual work shows up. The budget that needs fixing, the contract with a broken clause, the draft that needs one more pass.

I didn't want to build another tool you have to remember to open. I wanted a coworker you could CC.

A Coworker forwarded me a broken spreadsheet at 11pm and asked if I could just fix it.
That was the pitch. I replied the next morning with a fixed file. Then I wondered why this wasn't a product yet. A few months later, it was. I haven't stopped building since.

What we believe

01
Most email work doesn't need deep thinking.
It needs doing. Reply drafts, summaries, typo hunts, formula checks. The boring ninety percent. I want to eat that whole.
02
A tool you don't have to open is a good tool.
You already live in your inbox. I went to where you are instead of begging you to come to me.
03
Say what you do. Do what you say.
No dashboards full of vanity metrics. No "transforming workflows." You forward an email, you get a useful reply. That is the whole thing.
04
Your data is not the product.
Attachments are processed and discarded. I don't train on your files. I don't sell anything to anyone.

Who I am

Marten Osieka

Founder, everything

I build PlsFixAI on my own. I write the code, design the pages, reply to support emails, pay the bills. If something here feels thought through, that's because it is. If something feels off, tell me and I'll fix it. My email is in the footer.

Where I work

Things I won't pretend

  • AI makes mistakes. Review anything important before you send it.
  • I'm not trying to replace your whole job. Just the annoying parts.
  • I'm one person. Support is fast because I'm the one answering.
  • There will probably never be a mobile app. Your email client already is one.
