Problem
Normal browsers are Tab Hell for ADHD brains.
You think forty-seven open tabs is your fault. It isn’t. Tabs assume strong working memory and linear thinking. ADHD and AuDHD brains have neither to spare. The cognitive tax compounds all day.
Forty-seven open tabs
Each one a thought you’re afraid to lose. The browser becomes the overwhelm you opened it to escape.
An invisible daily tax
Tabs hide. Your brain has to remember what’s behind each identical favicon. That’s working memory, one of the executive functions ADHD compromises most. We’re being asked to do all day what we’re structurally worst at.
Gone after every restart
One update, one crash, one “Restore session?” you clicked too slow. A week of thinking, gone before coffee.
The tab was the task
The form you never submitted. The reply Sarah is still waiting on. The dentist you keep not calling. They weren’t tabs. They were tasks, and they didn’t get done.
Fix
Out of the mess, onto Trails®.
Click a link. It branches. The page you came from is still there. Your browsing turns into a literal map of your thinking, drawn automatically while you browse.
Tangents aren’t failures of focus. They’re how your brain finds good ideas. Collapse what you’re not using. Out of sight stops meaning gone.
Tab managers and blockers tidy the symptom, then hand the remembering back to your brain. Trails® aren’t another coping tool. They do the remembering.
Your brain isn’t broken. Your browser is.
Rabbit holes are the point
Take the tangent. When you surface an hour later, the route back is still drawn.
Take a Trail with you
Drag any Trail out of the sidebar and it lands as markdown: every page, every branch, ready to paste into your notes.
Collapse, don’t close
Fold a Trail away. It doesn’t leave. Tomorrow, expand it. Everything where you left it. A tidy desk you didn’t have to tidy.
Every option stays open
Compare flights, products, papers, recipes. Each option is a branch in the same Trail, in the order you found them. Nothing closes until you say so.
I have not clicked 'back' in a long time with Horse.

Your browser should remember things so you don’t have to.
Every open tab is a thought you’re holding in your head. Put it on the screen instead. Pages stay where you left them, including after you close the laptop.
Daniel Jaeger, a BACP-registered psychotherapist with ADHD, told Pascal in one sentence: Horse Browser externalises executive functioning, that is why it works for ADHD brains. We call it relief.
Survives every restart
Updates, crashes, force-quits. Reopen Horse and the week of thinking is still there. No “Restore session?” roulette.
Switch contexts in one click
Fold the project you’re not on. Expand the one you are. Tomorrow, swap them again.
Organize how you want
Name your Trails®. Add emojis. File the dentist under Today and park the tea spiral in 🐇 Rabbit Hole. There’s no right way. That’s the point.
Quiet by default
Ad blocking on. No popups, no notifications, no autoplay. A quiet corner of the internet, because most of the rest is loud at you for money.
Horse Browser is my quiet, safe internet where I am free to explore something new.

Hold every thread at once. Drop none.
Life yanks you around all day. The deadline, the dentist, the rabbit hole. Each one is still going, however many you have open at once.

Whatever else is happening today
I booked a hotel with 0 cognitive load despite having 15 tabs open. I've been talking about it to everyone.

Two windows.
One set of Trails®.
Open a second window and your Trails® are already there. The sidebar is shared across every window. The page you’re looking at is yours alone.
Put your reading on the second monitor and keep working in the first, both drawing from the same map. A new window in any other browser is a blank slate. In Horse it’s another view of the same work.
One sidebar, every window
The tree of Trails® is the same wherever you open it. Add a page in one window and it is already in the other. There is only ever one map, no matter how many windows you point at it.
Each window holds its own page
The sidebar is shared. The page in front of you is not. One window can sit on the matcha article while the other books the flight, and neither one yanks the other around.
Made for a second screen
Park your reading on the second monitor and keep working on the first. Two screens, two pages, one set of Trails® feeding both. Your eyes move; the work stays put.
Collapse once, fold both
Collapse an area in one window and it folds shut in the other too, because there is nothing to keep in sync. It was the same branch the whole time.
Exit
Your Trails®
aren’t trapped.
Drag a Trail out of the window and it’s markdown. The whole branch, indented, links and notes intact. Drop it into a doc, an email, your notes app.
Nothing is locked in a proprietary format. Your map of a topic is plain text the moment you want it somewhere else.
The whole subtree, outlined
Not the one page you grabbed. The area, its children, their children, every nesting level, as a markdown outline that already looks like an outline.
Links stay links
Every page comes out as a real markdown link with its title and its URL. Paste it anywhere and the whole map is still clickable.
Your notes ride along
Folders, projects, the tasting notes you typed at two in the morning. Whatever you tucked inside the Trail comes out with it, right where you left it.
Drops into anything
It is plain text. Obsidian, a Google Doc, an email, the back of a napkin if you can find a way. No export button, no proprietary file, nothing to escape from.
Speed
Keys, not clicks.
Move through your Trails® without reaching for the mouse. Jump to the next tangent, collapse a whole branch, open the one you want. Your hands stay where they were.
Every shortcut shows in the corner as it is pressed, so you pick them up just by watching.

People who think in tangents keep writing us reviews.
I love the hierarchical tab feature. Soooo much better implemented than all the extensions for Firefox or Chrome.

Really happy with Horse Browser. After a couple of weeks it fully replaced Arc for me. I'm feeling more productive and organized with it.

Horse Browser has been my daily driver since the day I downloaded it.

I just look to the left and clearly see how I got here. It's lifted the mental load of organizing my research while I'm researching.
