Daily Idea - Twitter, With Memory
Leaked Group Chat
Twitter, But You Can Remember
The One Liner
Your Twitter feed, with memory.
The 140 character tweet (or X) version
You read great tweets every day and forget them. This Chrome extension remembers what you read and lets you search it later by idea, not keywords.
The Longer Story Version
The Problem
Twitter/X has quietly become where thinking happens.
You read something sharp. It reframes a problem. It unlocks a new way of seeing something you’re building. You pause. You nod. You move on.
And it’s gone.
Bookmarks require effort, so you don’t use them.
Likes don’t mean “I want this later.”
Screenshots pile up and never get searched.
Threads disappear into the feed forever.
You remember the idea, not the wording.
You remember the insight, not the author.
For founders, writers, researchers, and internet-native thinkers, Twitter isn’t entertainment. It’s a thinking surface. And right now, it has no memory.
The Solution
A Chrome extension that quietly remembers the tweets you actually read and lets you find them later by meaning, not exact words.
As you scroll, it pays attention to what you pause on.
Those tweets are saved automatically, without you doing anything.
Behind the scenes, each tweet is turned into a simple “meaning snapshot,” so later you can search the way humans remember things.
You can type:
“that tweet about pricing psychology”
“a thread on why marketplaces break”
“an insight about AI replacing managers”
And it finds the tweet, even if you don’t remember who wrote it or how it was phrased.
You can sort by time, topic, or how long you lingered on it.
If you want, you can export ideas into Notion, Obsidian, or your notes app.
This isn’t bookmarking.
It’s giving your feed a memory.
How We’d Build It
Phase 1: Prove the Moment
This is technically possible today, with smart limits.
A Chrome extension, Twitter/X only
Detect tweets already rendered as you scroll
Only save tweets you pause on, not everything
Convert tweet text into meaning-based representations so idea search works
Local-first storage, no accounts, no uploads
Built fast with vibe-coding tools like Cursor, Replit, or Windsurf
The goal isn’t completeness.
It’s the first moment where you search a half-remembered idea and it shows up.
Phase 2: Make It Feel Safe
The hard part isn’t AI. It’s trust.
Background processing so performance stays invisible
Clear limits on storage or rolling history by default
Plain-English explanations of what’s captured and where it lives
Opt-in syncing only, never assumed
If this feels creepy, it fails.
If it feels obvious, it wins.
Phase 3: Scale the Brain
Once the habit forms, expansion is natural.
Why It Needs to Exist
People increasingly use Twitter/X to think in public.
AI finally makes “search by idea” practical.
Valuable insights are lost every day to scrolling.
The cost of forgetting compounds quietly.
Browser extensions can change behavior without platform permission.
This idea sounds magical.
But it’s really just good engineering and restraint.
Which is exactly why it should exist.

Leaked Group Chat: “Does This Actually Work?”
Builder:
Ok, hear me out. A Chrome extension that remembers the things you scroll past and lets you search them later by idea. This is obviously doable. The browser already sees everything. You don’t need platform APIs. You’re just adding memory to behavior people already have.
Skeptic:
Doable isn’t the same as durable. Platforms change their DOMs all the time. One tweak and your extension breaks. You’re building on sand. Best case, it works for a while. Worst case, you’re in permanent whack-a-mole mode.
Power User:
I don’t care. I’d pay instantly. I read ten smart things a day and lose all of them. I don’t bookmark. I don’t like things. I just move on and hope my brain keeps it. It doesn’t.
Privacy Brain:
That’s the part that scares me. “Remembers everything you read” sounds great until it doesn’t. If this uploads data by default, it’s dead on arrival. This only works if it’s local-first, no accounts, no surprises. Trust isn’t a feature here. It is the product.
Builder:
Agreed. Local storage. Opt-in sync later. Only save what you actually pause on. No dark patterns. You can do this without being creepy.
Cynic:
If it’s so obvious, why doesn’t Twitter already do it?
Builder:
Because platforms optimize for engagement, not memory. Forgetting keeps you scrolling. Memory makes you reflective. That’s not great for ads.
Skeptic:
Still feels niche. How big is “people who want a searchable brain”?
Power User:
Big enough. Founders. Writers. Researchers. Anyone who thinks online instead of consuming. This isn’t a mass-market feature. It’s a sharp tool for people who feel the pain every day.
Privacy Brain:
And if you get the trust wrong once, you’re done.
Builder:
True. But if you get it right, it becomes invisible infrastructure. The kind people don’t talk about until it’s gone.
Cynic:
So it’s not bookmarking.
Builder:
No. It’s admitting that scrolling is thinking now and giving that thinking a memory.
Silence.
Someone types:
“Wait… why doesn’t this already exist?”
That’s the tell.
The One You Missed
There’s a startup idea you would’ve built if you’d seen it six months earlier.
That’s the frustrating part of building: it’s rarely about skill. It’s about timing.
NTE Pro is where timing lives.
A searchable database of 6,500+ real startup ideas, surfaced from patterns most founders don’t notice until it’s too late.
No motivation quotes.
No trend-chasing.
No “just start” advice.
Just ideas that make you stop and think:
“I should’ve seen this earlier.”
NTE Pro is $99/year.
Five minutes in and you’ll know if you missed one.
Why Recent Funding Matter (and Why We Built WhoFiled)
Most startup ideas don’t come from trends.
They come from pressure.
You can see that pressure in recent fundraises, the public disclosures companies make when they raise money. Not press releases. Actual fundraises that show where capital is responding to real problems.
That’s why we built WhoFiled.
Look at the recent filings we’ve been digging into:
Oxide Computer raising $184M to rethink owned compute.
Ventiva taking on fanless cooling as chips get hotter.
Freeform Future betting big on autonomous metal factories.
NMI doubling down on embedded payments infrastructure.
DeepTrust and InfiniteWatch responding to deepfakes and AI agent risk.
None of these are “idea trends.” They’re reactions to systems under stress.
WhoFiled makes these fundraises easy to explore, how much was raised, how it was structured, and why that matters when you’re generating ideas or building your business.
This is how we use WhoFiled inside NTE: not to predict the future, but to study what people are already paying to fix.
Right now, WhoFiled is free for a limited time, with a ton of features to be unlocked (if you sign up)
If you want better ideas, stop guessing.
Follow the pressure.
