Why a New Browser Isn't the Answer

Every few years, someone tries to reinvent the browser: faster, cleaner, AI-native, better tab management. But most of us never switch.

Browser Lock-In
Chrome is sticky. Safari is default. Arc is niche.
Change is Hard
Changing browsers is like changing neighborhoods.
Enhancement > Migration
People want better experiences, not new places.

So the question becomes: What if the next leap isn't a browser? It's a layer on top of your existing one?

What Is an Agent in the Browser?

An agent is not a chatbot. Not an app. Not a search engine. It's a co-browsing assistant that thinks with you.

An agent is:

Lightweight Layer

Watches, learns, and assists silently

Present Inside Your Browser

Extension, overlay, sidebar, or ambient UI

Contextually Capable

Summarizing, bookmarking, surfacing, recommending

Personalized Intelligence

Adapts to your curiosity, habits, and workflow

Use Cases for a Browser Agent

Auto-Save Knowledge
Any highlight, link, or idea you liked - stored and contextualized automatically.
Suggest Related Sites
While reading, the agent recommends 3 more ideas nearby in your interest graph.
Curate on the Fly
Turn 5 open tabs into a shareable web playlist or collection instantly.
Ambient Summaries
TL;DR of pages without clicking anything - hover or background processing.
Cross-Site Memory
Remembers when you've seen similar content before, prevents duplicate discovery.
Smart Sharing
One-click creation of themed collections to share with others or revisit later.

Why Now?

1

AI Models Are Fast and Local

No need for heavy backends or servers. Processing can happen in-browser.

2

Users Are Burned Out on App Switching

Extensions are lighter and more native than standalone apps.

3

Browser is Untouched Real Estate

It's where curiosity happens, but no one owns the discovery layer yet.

4

LLMs Thrive on Context

And the browser is full of it - browsing history, current tabs, search patterns.

Why This Beats Building a Platform

Most startups want to build a new platform - their own space, their own UX. But users don't want more places. They want better experiences in the spaces they already use.

Agents let you:

Ride Existing Behavior

No habit change required

Own Ignored Moments

Tab switching, highlighting, idle time

Build Compounding Trust

Persistent, personalized learning

Think: Notion + ChatGPT + Pinterest + Readwise - as a passive, persistent presence in your browser.

This Is What Stacks Is Betting On

Stacks (stacks.im) is building exactly this: a browser-native agent that helps you discover, curate, and revisit the best of the web.

Not another app. A partner that sits alongside you - present, quiet, useful.

Browser Extension

Web Platform

Syncs across devices, shareable collections, social discovery layer.

The Future of Browsing

The future of browsing is not replacement. It's reinforcement.

You won't switch. You'll stack.
