InBrackets [AI]

// AI assistance, right where you type.

When I was 15, I was having coffee with my father in his backyard. His dog was running around, as usual. I said,

"Can you imagine? This dog has never seen anything beyond these four fences."

My father took a slow drag from his cigarette and replied:
"She thinks that's how the world is."

I'm building InBrackets [AI] because I believe it shouldn't be that way. Have you noticed how often you switch tabs just to ask ChatGPT something, copy the content, and paste it back?

// Let's rethink all of it

Why switch tabs? Why even reach for the mouse or press extra buttons? Wherever you're about to type something — that's exactly where AI should live. Write your thoughts, surround your prompt in square brackets, and watch the answer replace the question.

// How it works

Most AI tools work like this: you're writing, you get stuck, you open a new tab, type a prompt, wait, copy, paste, close the tab, and continue. That's six interruptions for one thought.

InBrackets works differently.

You're writing. You need AI. Instead of stopping — you type [what you need] right there, and keep going. When you close the bracket, it executes.

plaintext · you type this
Hi Johnny, I'm in Kraków right now, but I can't really go for a walk because today [describe the weather in Kraków today]

The result replaces the placeholder, exactly where it belongs.

result.diff 1 insertion, 1 deletion
...I can't really go for a walk because today [describe the weather in Kraków today]
+ ...I can't really go for a walk because it's partly cloudy, around 11°C.

You can put anything in the brackets:

examples
[translate 'Buenos días, ¿cómo estás?' to English]
[rewrite 'hey can u send that file asap' more formally]
[subject line for an email about postponing a meeting to next week]
[one sentence: why writing clear commit messages saves time]
[three bullet points: pros of async communication in remote teams]
💡 The final text looks like you wrote it yourself. Because in a way, you did.

// Who it's for

If you write on the web — this is for you.
But more specifically:

The one replying to emails all day
Gmail · reply
Hi Marcus, thanks for reaching out. [politely decline a collaboration proposal, suggest reconnecting next quarter]
The developer writing commit messages and docs
terminal · git commit
[conventional commit: fixed auth token expiry not being handled in the refresh flow]
The one posting on LinkedIn, Twitter, Telegram
Twitter · compose
[two punchy sentences: just shipped a side project after 3 weeks of evenings, honest and without hype]
The one who already uses ChatGPT for everything
You know the flow: write → Cmd+Tab → paste context → prompt → wait → copy → Cmd+Tab back → paste → continue. InBrackets doesn't change what you ask. It removes the round trip.
