I've been super annoyed with having to open bloated markdown apps or editors just to look at a README, or proof one before I push it, so I created the markdown app I always wanted.
Meet Peekdown, a tiny markdown previewer who's always there for you but never gets in your way.

Adding MCP to brevinotes.com. Tweeted from inside a car was once too. Life is amazing.
working on graphics and claude added this text. can't tell if this is cutting-edge or he wants me to look stupid
Just submitted a new build of Brevi which now includes the iPhone duo. Curious to see how long, or fast this takes to review.
Claude updated a Markdown document while I was reading it. peekdown.app has a file watcher and picked up the changes, allowing me to scroll through the diff to see exactly what changed.
Claude was testing checklists in my notes app in the background and I was posting something on X. Right as I was about to hit the Post button the text updated with "eggs" and "oat milk" and I was like wtf am I haunted?
"Claude, new rule: make sure the app you're testing is in the front before sending keypresses." 🙄
I'm terrible at marketing, but trying to get better. This one reply sent the app to #1. Keep pushing, you never know which one will pop off.

Has anybody at @X tried logging in with Safari or iPhone using the Passwords app and 2FA?
No. The answer is no. What a horrible experience.
I just had a flashback to the very first website I deployed.
It was 1996, and back then we called it "uploading."
I was a freelance print designer doing one-sheets, compact discs, and logo designs for record labels when I got a call from a television production company who liked my style. They wanted me to do their show graphics... and build websites. I had zero experience with either but thought this sounded like fun. And hey, a steady paycheck is a steady paycheck!
I bought a book on how to build websites and was immediately confused BY HTML
Not a good start.
Fortunately there was a WYSIWYG program Adobe had just released called Pagemill that was supposed to let you create sites without writing code. So I snagged a copy before I got fired and WAS IMMEDIATELY CONFUSED BY THAT TOO.
Fortunately they had an 800 number.
I designed the site in Photoshop. Sliced (that's what we called it back then) up the images and brought it all into Pagemill. I barely remember what that was like, but I managed to finally complete the site and was desperate to get it uploaded to the server.
The server. My god was that terrifying. What in the hell is a web server? I'm supposed to be the "web master" and I don't even know what a web server is, let alone how to get this site on it so that somebody else can see it.
I was ready. It was Friday night. All by myself in a little office in Boca Raton. I remember glass walls.
I opened MacTCP and connected to the Internet.
The 56k modem fired up and made those beautiful, screeching modem noises that you in the old guard will remember so well. The beeping. The whining. Those tones that said "your life is about to change."
I then called Walid at the hosting company and asked him what to do. This man was so patient and kind. He wrote the contact form for me in Perl. He always took my frantic, desperate calls and assured me everything would be fine. Even on this Friday night.
"Open Fetch. Create a new connection with the information I sent you, then select your website files and click PUT" he said, as I dried off my palms. "It'll upload."
We hung up. I was on my own.
I selected all the files. Drew in a breath, paused, then clicked the button. I was vibrating.
It was so slow. Those heavily compressed JPGS. The 128 color GIFS. How long does it take to upload a .html file? I DON'T KNOW! Did I even do any of this right?
The Fetch mascot 'Newbie' ran in place. I paced back and forth... This was taking forever.
The alert alerted. Or barked, actually. All files were finally uploaded. Was that it? Was it that simple? I opened Netscape Navigator and typed in the URL.
And there it was. Just as I had designed it. Just as I had seen it on my Mac. But it was live on the internet. It was different. It was like hearing your band's song on the radio for the first time. It was real.
I jumped out of my chair and whooped.
That night changed me forever. Alone. On a Friday night in a little office in Boca Raton with glass walls and the smell of an Olive Garden salad in the distance. Jumping up and down because I accomplished something that I now take for granted.
Actually, no. I'm still terrified.
