Your notes are a
graveyard
of good ideas.

You wrote things down. You just can't tell — three days later — what was urgent, what was decided, what you still need to do. Four tiny symbols fix that.

Meeting notes · Monday · Q3 planning
📋 Normal notes (Thursday, trying to remember)

Product launch is planned for Q3. There are some concerns about the onboarding flow, still being revised by design. We need to align with marketing on the campaign timeline. It's not clear whether we'll hit the feature freeze deadline. Team suggested a soft launch might reduce risk.

⏱ You spent 4 minutes re-reading to find the actual problem.

The Problem

You've definitely been here before.

It's not a memory problem. It's a structure problem. Everything looks the same, so your brain has to read every word every time.

📝
After a meeting
You took notes. Three days later you open them and they're a wall of sentences. Which ones were actions? Which were risks? Which did you already resolve?
"Was this a decision or just someone's opinion?"
📚
While studying
You highlighted everything because everything felt important. Before the exam you open your notes and everything is equally yellow. Nothing stands out.
"I took 12 pages of notes and still can't find the key point."
🧠
Making a decision
You wrote out all the pros and cons. Then your spouse adds reasons. Then your colleague adds more. Now it's a 200-word paragraph and the decision is no clearer.
"I wrote it all out and still don't know what to do."
The Solution

Four symbols.
That's it.

You don't need all twelve CLN operators on day one. Start with these four. They cover 90% of everything you write.

These work in any app you already use — Notion, Google Docs, Word, Slack, your phone's Notes app, even paper.

!
! — Warning / Risk
This line is a problem, a risk, or something that could go wrong. It should catch your eye the moment you open the file.
! Milk expires tomorrow
! Budget approval still missing
.
. — Task / Action item
Something that needs to be done. Think of it as a bullet point, but one that specifically means "someone needs to do this."
. Book the dentist
. Send the Q3 report to Sarah
→
→ — Result / Conclusion
What happened, what was decided, or what the outcome is. This is the "therefore" of a situation.
→ Went with Option B
→ Launch moved to November
?
? — Open question
Something you still don't know. A question that's unresolved. When you scan your notes later, these are the gaps you need to fill.
? What's the refund policy?
? Who owns the onboarding docs?
Also new in v2.8

Now you can emphasise
inside any line.

The symbols tell you what type a line is. The new inline formatting lets you highlight what matters most within that line. Works exactly like in Markdown or any chat app.

**bold**
Make words stand out
Wrap anything in double stars to make it bold. Great for names, amounts, deadlines — anything your eye should land on first.
! call Sarah before Friday 5pm
. pay €240 invoice
~~strike~~
Cross things out
Put double tildes around anything that's been replaced, cancelled, or is no longer true — without deleting the history.
→ launch Oct 28 → Nov 5
= budget: €800 €950
==highlight==
Highlight the critical bit
Double equals marks a highlight — like a yellow marker on paper. For the one thing in a line that someone must not miss.
! contract needs signature by EOD
~ key tradeoff — speed vs. quality

One rule: these only work inside a line, not at the start. The symbol at the start always tells you the type. The formatting inside tells you what's important within it.

Real Life Examples

Works wherever you take notes.

Pick a situation you recognize. See the before and after.

Before Hard to scan

Q3 planning call. Jake mentioned the API is unstable and might affect the release. We discussed moving launch to Nov 5th instead of Oct 28. Sarah needs to update the roadmap doc. Still waiting on legal to review the new TOS. Budget for extra QA hasn't been approved yet.

Re-reading takes 2+ minutes to extract the actual to-dos.

After CLN Instant clarity
=Q3 Planning Call
!API unstable — may affect release
~Launch date debated: Oct 28 vs Nov 5
→Moving to Nov 5
.Sarah updates roadmap doc
?Legal review of new TOS — still open
!Extra QA budget not approved

Open the file. Both ! lines jump out. You know the blockers in 3 seconds.

Mitosis is the process by which a cell divides into two daughter cells. The cell goes through prophase, metaphase, anaphase, and telophase. The nuclear envelope breaks down during prophase. Chromosomes align at the metaphase plate. Sister chromatids are separated during anaphase. Two new nuclei form in telophase. Different from meiosis.

Before the exam, you re-read it all. Again.

After CLN Reviewable in 30 sec
=Mitosis · cell division → 2 identical daughters
.Stages: Prophase → Meta → Ana → Telo
!Nuclear envelope breaks down in Prophase
*Chromosomes align at metaphase plate
*Sister chromatids separate in Anaphase
~Mitosis vs Meiosis · easy to confuse
?What triggers mitosis to start?

? shows you what to look up. ~ flags the comparison trap. Review in 30 seconds.

Before Hard to scan

Lisbon trip in April. Want to see Belém Tower and Jerónimos Monastery. Need to book flights by end of month for good prices. The apartment on Airbnb looks nice but has mixed reviews about noise. Check if we need a visa. Budget around €800. Might rent a car for the Sintra day trip but not sure if it's worth it.

You re-read before booking every single thing.

After CLN Action-ready
=Lisbon · April
!Book flights by end of month
?Visa required?
.Must-see: Belém Tower + Jerónimos
~Airbnb apt · good price, noisy reviews
+Sintra day trip · probably worth it
?Rent car for Sintra or bus?
=Budget · ~€800

Open this. The ! screams "book flights now." The two ?s show exactly what's unresolved.

Before Hard to scan

Should I take the new job? The salary is higher by €12k. But the commute is 45 minutes longer each way. The team seems good and the tech stack is interesting. My current role is comfortable but there's no real growth path. I'd have to learn a new domain. Wife thinks I should go for it. Not 100% sure about work-life balance there.

You re-read this five times and still feel stuck.

After CLN Structure = clarity
?New job — take it?
++€12k salary
+Interesting tech stack + good team
−+45 min commute each way
−New domain = ramp-up time
!Work-life balance unclear
~Current job: comfortable but no growth
*Wife: go for it
?Ask them about remote flexibility first

Now you can see the actual shape of the decision. The ! shows what to resolve before deciding.

Normal prompt Vague output

Hey, can you help me think through whether I should redesign my landing page? I'm not sure if the current one is working. Traffic is okay but conversions are low. I also want to add more features but not sure which ones. Budget is limited.

AI gives a generic 5-paragraph answer. You read it all and still don't know what to do first.

CLN prompt Structured answer
=Goal: improve landing page conversion
!Conversions low despite OK traffic
?Should I redesign now or add features first?
~Limited budget — can't do both
.Give me: prioritised list of 3 actions
→Format: one line per action, most urgent first

AI knows exactly what you need. You get a short, structured answer instead of an essay.

Who Uses CLN

You don't need to be
a developer.

CLN was built by developers, but it works for anyone who takes notes.

"I type ? before every concept I don't fully understand. Before the exam I search '?' in my notes and instantly have my review list."

✍️
The Writer
Content, research, ideas

"I have one long file of research notes. → lines are the conclusions I actually want to use. Everything else is just context I can skip on re-reads."

How to Begin

Start in 5 minutes.

You don't need a new app. Open whatever you write in right now.

01
Learn the first symbol today: !
Go through your last note or document. Find anything that's a risk, a problem, or something urgent. Put ! at the start of those lines. That's it. You just started.
! Client hasn't signed off on scope
02
Add tasks: . and outcomes: →
In your next meeting or study session, use . for anything that's a to-do, and → for anything that was decided or happened. After a week, these two habits alone will transform your notes.
. Follow up with legal by Friday
→ Decision: move to the cloud platform
03
Mark the gaps: ?
Whenever you write something down and realize you don't actually know the full picture, put ? on it. These become your research list. Search for ? in any file to instantly see every unresolved question.
? What's the maximum table size in this database?
04
When you're ready, go deeper
CLN has 12 operators total — comparisons, context, cross-references, status markers. Plus inline formatting: **bold**, ~~strikethrough~~, ==highlight==. The 10-minute interactive walkthrough teaches them all in order. You'll never use them all at once, but having them when you need them is powerful.
