Closing tabs kills your tasks.

Replace tabs with Trails® and keep the task alive: see your whole thought path, collapse it to do something else, then come back later and pick up right where you left off.

Problem

Normal browsers are Tab Hell for ADHD brains.

You think forty-seven open tabs is your fault. It isn’t. Traditional tab bars hide why each page matters, then make working memory hold the lot. One interruption becomes archaeology. Three can bury the afternoon.

Tab hell, reconstructed. Six windows, forty-seven tabs, and a cat video you will never find again.

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.

Restored as a pile

Most browsers can reopen the windows. They return forty-seven tabs as forty-seven strangers and declare the rescue complete.

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.

Relief

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 his description of the accommodation, not a treatment claim. We call it relief.

A Tuesday in Horse: two projects, one parked rabbit hole, today’s errands, and the reply to Sarah in its own little window. The dentist still needs booking.

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.

Everyday

Keep every thread without holding them all.

Life yanks you around all day. The deadline, the dentist, the rabbit hole. Leave one, finish another, and come back without rebuilding the scene from browser debris.

Falling down rabbit holes

Your brain wants to branch. Let it. The rabbit hole stays drawn behind you when you come back up.

Researching anything serious

Papers, comparison shopping, or trip planning: see how you got from A to Z in the order you thought it.

Running multiple projects

Dashboards, docs, and client work each get their own Trail, ready to fold when you switch.

Whatever else is happening today

The dentist booked, the reply to Sarah sent. An Animal Crossing wiki spiral, the slow process of finding a chair that doesn’t fight you. Different Trails®. Nothing lost when you switch.
I booked a hotel with 0 cognitive load despite having 15 tabs open. I've been talking about it to everyone.

Sync

Two windows.
One set of Trails®.

Open a second window and your Trails® are already there. Both windows share the same sidebar, while each can show a different page.

Put your reading on the second monitor and keep working in the first, both drawing from the same map. Ordinary browsers give each window its own tab pile. Horse gives both windows the same map.

The same Trails® in both windows, Trailheads and all. One is reading about matcha, the other is booking the trip. The sidebar stays in sync; the active page does not.

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.

Grab the Trailhead, drag it out. Out comes a clean markdown outline of the whole subtree, links and tasting notes included, dropped straight into your editor.

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.

No cursor in sight. The selection walks the tree, a branch folds shut, and the key combination lights up bottom-right as it lands.

Proof

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.

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.

A safe home for my interests. No noise, no friction. Just me, my Trails, and my curiosity.

This is the first time I paid for a browser, and I do not regret a single dollar of it.
