Horse

Closing tabs kills what you meant to finish.

Those tabs aren’t clutter. They are promises to your future self: finish the form, answer Sarah, read the brilliant thing. Made for people with ADHD, Horse replaces tabs with Trails®, keeping every page connected to the page that led you there. Follow the fascinating thing. Get interrupted. Come back tomorrow. The whole route is still on the screen, waiting to carry you forward.

When tabs fail

The pages survived. The task disappeared.

By late afternoon, the browser is humming with unfinished life: 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 survived. What disappeared was the task connecting them.

Restoring the window restores the evidence, not the idea. A row of favicons cannot tell you where the search began, which link changed your mind, or what still needs doing. Your browser saw every page lead to the next and then threw away the map. Horse keeps the map. Ha! The task lives!

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.

Horse turns that map into Trails®. Open a link and the new page appears beneath the page that led you there. Open another and the branch grows. The browser draws the route while you do the interesting part: asking, comparing, wandering, deciding.

Pascal has ADHD. He did not discover this problem in a strategy meeting; he kept losing his own work. So he built a browser that gives the remembering to the machine. Your brain isn’t broken. Your browser is. Browsers are code, and code can be changed. Magnificent news!

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.

Come back

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

The doorbell rings. A call runs long. Suddenly it is midnight and the laptop must close. Ordinary browsers turn that moment into tomorrow’s excavation: which form, which source, which branch, why was this page open? Horse keeps the task assembled while life gets on with being life.

Daniel Jaeger, a BACP-registered psychotherapist with ADHD, describes this as an accommodation, not a treatment. Horse moves part of the remembering out of your head and onto the screen. When you return, the pages still make sense together. The victory is not merely that the pages survived. You were allowed to go live your life.

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.

A real day rarely contains one obedient task. A message lands in the middle of research. The research raises a question about the trip. The trip reminds you to book the dentist. Somewhere in there, an Animal Crossing mystery acquires the dignity of a national inquiry. This is not a failure of focus. It is Tuesday.

Give each mission a Trail. Answer what is urgent. Follow what is fascinating. Fold one project away and open another without sweeping the first off the desk. Curiosity and completion no longer have to duel over the last surviving tab. A full day may contain multitudes!

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 room to spread its wings. Put the source beside the draft, or the booking beside the research that inspired it. Each window can show a different page while both share the same Trails®. Open a branch on the left and it is already waiting on the right.

Two monitors stop behaving like neighbouring islands and become one magnificent desk. Look left to read, right to write, and anywhere to choose the next page. The second monitor has waited years for this promotion. Today, it fulfils its destiny!

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.

Browsing eventually becomes something else: a report, a plan, a handoff, the beginning of the thing itself. Drag out a Trailhead and Horse writes the whole branch as plain Markdown. Links stay linked. Folders keep their shape. Notes remain beside the pages they explain.

Keep the work in Horse because Horse is useful. Take it elsewhere because the work is yours. The stable door is open, deliberately! Once the work is safely yours, let the keyboard make Horse disappear beneath your hands.

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.

Soon the sidebar stops feeling like a map you consult and becomes a place you know. Select another Trail, fold a branch, step to its parent, move it, or open a new subtrail without dropping the thought already in flight.

Learn one shortcut when it earns its keep, then another. Eventually the browser responds at the speed of the thought. The interface asks for less of you; the idea 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.
