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. Coming from Arc or another sidebar browser? See how Horse compares.
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 and it branches. The page you came from stays right above it while your browsing turns into a literal map, drawn automatically as you go.
Tangents are how your brain finds good ideas, so take the interesting one! Collapse what you are not using and out of sight stops meaning gone.
Tab managers are excellent for organising tabs, and blockers are excellent for keeping a site closed. Trails® add a different job: they remember the path and keep the task ready for your return.
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 and expand it tomorrow with everything where you left it. A tidy desk you did not have to tidy, which is the finest category of desk.
Every option stays open
Compare flights, products, papers, or recipes with each option branching inside the same Trail. 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, described the mechanism in one sentence: “Horse Browser externalises executive functioning. That is why it works for ADHD brains.” We call it relief.
Survives every restart
After an update, crash, or force-quit, reopen Horse and the week of thinking is still there. No “Restore session?” roulette.
Switch contexts in one click
Fold the project you are not using and expand the one you need. Tomorrow, swap them again with one click.
Organize how you want
Name your Trails®, add emojis, file the dentist under Today, and park the tea spiral in 🐇 Rabbit Hole. Build the map that makes sense to you.
Quiet by default
Horse keeps its own interface still while your pages branch inside a calm, predictable sidebar. Make yourself a quiet corner of the internet, with considerably fewer things leaping out of bushes.
Horse Browser is my quiet, safe internet where I am free to explore something new.

Keep every thread without holding them all.
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 a Trailhead 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 Trailhead, 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.
