Daily Idea - Shared Browsing Layer
Screen Share Is Dead (Or Is It?)
Multiplayer Internet for Teams Finally
The One Liner
Turn any website into a shared workspace
The 140 character tweet (or X) version
Browse any website together in real time. Multiple cursors, live chat, AI notes, shared decisions, and instant outputs. The internet finally becomes collaborative
The Longer Story Version
The Problem
The internet is where work happens.
But collaboration happens everywhere else.
You open Zoom. Share your screen. And immediately:
“Can you scroll?”
“Wait go back.”
“Where are you clicking?”
Half the team is passive.
Nobody is actually interacting.
And when the call ends?
No memory.
No structure.
No real output.
We turned documents into multiplayer (Google Docs).
But browsing — where most work actually happens — is still single player.
That gap is massive.
The Solution
Turn the browser into a shared, multiplayer environment.
Everyone joins the same live session.
Multiple cursors navigating at once
Scroll independently or sync views
Highlight, comment, react directly on the page
Voice and chat layered into the experience
But the real unlock:
AI is sitting in the session with you.
It watches what the team is doing and:
Summarizes what you’re looking at
Captures decisions and key takeaways
Flags friction, insights, and questions
Outputs clean notes, tasks, and summaries instantly
It’s not screen sharing.
It’s collaborative thinking, directly on the internet.
How We’d Build It
Phase 1: Prove the wedge (User Research Teams)
Goal: replace 1 painful workflow (user testing sessions)
Phase 2: Product + Growth Teams
Goal: become default for product reviews + audits
Phase 3: Multiplayer Internet Layer
Full browser (Chromium fork or Arc-style layer)
Permissions, roles, persistent workspaces
API + integrations (Slack, Figma, CRM tools)
Agent layer: “run research for me, then review together”
Goal: browsing becomes collaborative by default
Why It Needs to Exist
We’ve already made everything else multiplayer.
Docs → multiplayer
Design → multiplayer
Code → multiplayer
But the internet itself?
Still single player.
And that’s insane.
Because most work today is:
Research
Reviewing competitors
Watching users
Exploring products
This idea doesn’t create a new behavior.
It upgrades an existing one.
From:
meetings about the internet
To:
working directly on it together
If this works…
Screen share disappears.
And the browser becomes the most important collaboration tool in the stack.

Here’s the uncomfortable question:
Do people actually want this… or do they just hate meetings?
Because those are not the same thing.
On one hand, this feels inevitable. Every major tool has gone multiplayer. Docs, design, code. Browsing is just the last holdout. And once you see multiple cursors on a website, it’s hard to unsee. It feels obvious in hindsight.
But here’s the pushback.
Most teams don’t optimize for better tools. They optimize for “good enough.” Zoom works. Loom works. Notes kind of work. The pain is real, but it’s not screaming loud enough for most teams to switch behavior.
And behavior is the whole game here.
This isn’t a feature. It’s a workflow shift.
The real wedge isn’t “multiplayer browsing.” It’s one specific use case where the pain is unbearable — like user research or live product reviews.
Win there, and it spreads.
Miss that, and this becomes another “cool demo” product that everyone tries once and never adopts.
The upside is massive.
But only if it replaces something, not just adds to the stack.
Most people don’t struggle with execution.
They struggle with what to execute on. That’s the real bottleneck.
NTE Pro gives you 6,500+ startup ideas, but more importantly, it gives you angles you wouldn’t think of on your own. Ideas with wedges, timing, and actual business potential baked in. You don’t need to be “creative.”
You need to recognize what’s already working and move early. Scroll it like a menu. Steal one. Twist it. Launch it. This isn’t inspiration porn. It’s a starting point.
If you’ve ever said “I wish I thought of that,” this is where that stops. NTE Pro turns that into “I’m building that.”
Something important just happened. You just didn’t see it yet.
A company quietly raised. A product just launched. A team started building something that might matter in six months.
By the time it hits TechCrunch, it’s already too late. WhoFiled surfaces these signals as they happen—not what’s trending, but what’s emerging. You can follow a company, a market, or just a curiosity, and it connects the dots for you in plain language.
It’s not noise. It’s timing. Founders use it to spot competitors early. Investors use it to find deals before they’re obvious. Everyone else uses it to stop being late.
