Horse

Closing tabs kills what you meant to finish.

Those tabs aren’t clutter. Each one is something you cared enough to begin and still mean to finish. Made for people with ADHD, Horse replaces tabs with Trails®, keeping every page connected to the page that led you there. Wander as far as the work takes you. When life pulls you away, the route home is still on the screen.

When tabs fail

The pages survived. The task disappeared.

At the end of an ordinary afternoon, the browser can look impressively alive: the form, three train times, an unanswered message, the article that changed the question and, somehow, a cat refusing to acknowledge the vet. Every page is still there. What has vanished is the difference between the page you needed, the page that explained it, and the detour you enjoyed on the way.

Restoring the window only restores the evidence. A row of tabs cannot tell you what began the search, which link changed your mind, or what you still meant to do. The computer saw one page open another. Ordinary tabs simply hide that relationship. Horse keeps it.

Tab Hell, reconstructed: six windows, forty-seven tabs, one missing task, and the cat video that somehow survived everything.

Meet Trails

Follow anything. Find your way back.

Those relationships are the whole idea behind Trails®. Open a link and it appears beneath the page that led you there. Open another and the branch grows. A research session stops looking like twenty unrelated rectangles and begins to look like what it was: a question with a beginning, a few decisions, several excellent detours, and a way back.

Pascal has ADHD. He did not arrive at this by studying how other people lose work; he kept losing his own. Horse became the browser he needed, one that gives the machine the burden of remembering the route. Your brain isn’t broken. Your browser is. Browsers are code, and code can be changed. Magnificent news! Once the route is visible, an interruption changes character.

Park the whole Trail

Fold a Trail away. Open it tomorrow and the same pages are waiting. A tidy desk you did not have to tidy!

Compare without losing

Keep every flight, product, paper, or recipe together. Each contender stays beneath the page that introduced it.

I have not clicked 'back' in a long time with Horse.

Come back

Get pulled away. Come back. It’s all still there.

The doorbell rings. A call runs long. It is suddenly midnight and the sensible thing is to close the laptop. In a tabbed browser, each of those moments can turn live work into a reconstruction: which form, which source, which branch, why was this page open? Horse keeps the subject assembled while life gets on with being life.

Daniel Jaeger, a BACP-registered psychotherapist with ADHD, describes this as an accommodation, not a treatment. The machine carries part of the executive-function work that ordinary browsers hand back to you. When you return, the pages are still in working order instead of becoming a small archaeological site. The relief is not only that the pages survived. Your attention was allowed to go somewhere else.

Tuesday, ready to resume: two projects, one parked rabbit hole, today’s errands, and a reply waiting in its own window.

Quit and return

Quit, restart, or update Horse. Open it again and your Trails return. The task doesn’t pay for the software’s little adventure.

Name the work

Add a name, an emoji, and a Trailhead. “🐇 Tea research” beats twelve identical favicons.

Horse Browser is my quiet, safe internet where I am free to explore something new.

One day, many missions

Your attention can move. Your work stays put.

That permission matters because a real day rarely contains one clean task. An urgent message arrives in the middle of research. The research creates a question about the trip. The trip reminds you to book the appointment. Somewhere in there, an Animal Crossing mystery acquires the full dignity of a national inquiry. This is not a failure of focus. It is Tuesday.

Each Trail gives one subject a place of its own. Answer what is urgent. Follow what is fascinating. Fold one project away, open another, and return without sweeping the others off the desk. Curiosity no longer has to fight completion for the last surviving tab. A full day may contain multitudes!And sometimes one of those multitudes needs a second screen.

Research deeply

Curiosity can branch. Excellent! Go deep, then climb back through the same pages.

Compare your options

Every candidate stays beneath the page that introduced it, ready to compare.

Keep projects ready

Fold one project, open another, then return without rebuilding the tab pile.

Finish life’s errands

Book the appointment. Answer a friend. Investigate an Animal Crossing mystery. Tuesday deserves more than one row of tabs.
I booked a hotel with 0 cognitive load despite having 15 tabs open. I've been talking about it to everyone.

Every window

Two windows.
One set of Trails®.

Some work wants more room. A source belongs beside the draft. A booking belongs beside the research that inspired it. Horse lets each window show a different page without splitting the project into competing versions of itself. The same Trails® run through both, so a branch opened or folded in one window is already understood by the other.

That sounds like a small piece of plumbing. In practice, it turns two monitors from neighbouring islands into one desk. Look left to read, right to write, and anywhere to choose the next page. The browser handles the arrangement; your attention gets the room. The second monitor has waited years for this promotion. Today, it fulfils its destiny! Eventually, though, the work must leave the screen.

Matcha research in one window, the trip it inspired in the other.

One shared sidebar

Open another window. The same Trails®, including every new page, are already there.

A page per window

Show a different page in each window, from the same set of Trails®.

Read here. Write there.

Keep sources on one screen and your draft on the other.

Fold once, everywhere

Collapse or expand a branch in either window. The other follows.

Markdown export

Take your Trails®
with you.

Eventually, browsing turns into something else: a report, a plan, a handoff, or a record of what you learned. Drag out a Trailhead and Horse writes the whole branch as plain Markdown. Page titles remain linked. Folders keep their nesting. Notes stay beside the pages they belong to.

What began as a living piece of browsing can become a brief, an archive, or the outline of the thing you are ready to make. Software is easier to trust when the door remains visible. Keep the work in Horse because it helps. Take it elsewhere because you choose. The stable door is open, deliberately! Once the work is safely yours, the next question is how little the browser can interrupt you while you use it.

Drag out a Trailhead. Its full branch lands as Markdown.

Every page comes too

Every page, folder, and note keeps its place in the outline.

Links stay links

Titles and URLs remain clickable Markdown links.

Notes ride along

Even the tasting revelation from two in the morning stays where you put it.

Plain text. Yours.

Put it in Obsidian, Google Docs, email, or a napkin if your pen is sufficiently advanced.

Keyboard

Run Trails from the keyboard.

After a while, the sidebar stops feeling like a map you consult and begins to feel like a place you know. That is when the keyboard matters. Select another Trail, fold a branch, step to its parent, move it, or open a fresh subtrail without dropping the thought you were carrying.

You do not need to memorize a wall of shortcuts. Learn the one that removes today’s interruption. A day later, another earns its place. Eventually the browser responds at the speed of the thought, which is the closest a computer comes to good manners. The interface asks for less of you; the thought gets more of you. Yes, computer!

Move, fold, and open Trails without leaving the keyboard.

Rider reviews

Riders report back.

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.

Try Horse

Come back tomorrow. Know exactly where you were.

Bring Horse one real task, not a ceremonial test. Research the thing. Follow the useful link and the surprising one. Let the Trail grow as far as the work requires, then close the laptop when the day intervenes. Tomorrow, open Horse and see whether the task makes sense before you have had coffee.

If the route back is already there, the browser has begun carrying its share. You get to spend your memory on the work itself. Imagine that!
