You know you should post on LinkedIn — it just eats your week. Cassian does the reading, writing, scheduling, and reporting in one chat. About 5 minutes a day.

It sounds like you
Cassian learns from your real posts — not a generic template. Every draft comes back in your voice, your rhythm, your takes.
Your account is safe
Connects through the official LinkedIn login — Cassian never sees or stores your password. Voice notes transcribe on-device, and nothing publishes without your OK.
Notarized by Apple
Cassian is signed with an Apple Developer ID and notarized by Apple, which scans every release for malware before you double-click it.
It opens like an App Store app.
No “unidentified developer” warning. No right-click-to-open ritual. Cassian is signed with an Apple Developer ID and sent to Apple for notarization before every release — so macOS already knows who built it and that it’s clean.

In plain English, in one thread. This is the real card Cassian hands you in the app.
You already have three options. Cassian is the fourth.
LinkedIn is where B2B attention moved. The people winning there post every day — Cassian is how you keep up without it taking over your week.

I grew to 74,721 followers by posting on LinkedIn relentlessly — the reading, writing, scheduling, and learning, every single day. Cassian is the system I built to make that repeatable. I use it daily. Now it's yours.

No slides, no script — just me messaging Cassian and a post going live.
People stopped dreading LinkedIn.
I went from posting once a month to three times a week — and it actually sounds like me. First inbound lead came in nine days.
The reporting is the part I didn't know I needed. It tells me why a post worked and reuses the pattern. My reach doubled.
I send a voice note on my commute and there's a scheduled post by the time I'm at my desk. Five minutes, done.
The questions everyone has.
Will the posts actually sound like me?
Yes. Cassian reads your existing LinkedIn posts to learn your voice, hooks, and rhythm before it writes a word. You review and edit every draft — nothing goes out that doesn't sound like you.
Is this against LinkedIn's rules?
No. Cassian connects through LinkedIn's official login and posting API — the same sanctioned path other tools use. It never asks for your password or automates anything LinkedIn doesn't allow.
Is it safe to install an app from your website?
Cassian is signed with an Apple Developer ID and notarized by Apple, which scans every release for malware and staples the result into the app. Your Mac checks that before it opens, so Cassian launches without an “unidentified developer” warning — and Apple can revoke the signature if it were ever misused. Cassian also never asks for your LinkedIn password.
Does it post without me?
Only if you tell it to. You approve each draft; scheduling and auto-publish are opt-in per post. You're always in control of what goes live and when.
Do I have to be at my computer?
No. Message Cassian from the Mac app or Telegram — send a voice note or a screenshot on the go, and it drafts, schedules, and reports back in the chat.
Is it only for macOS?
The app is on macOS today, with Telegram live now and web coming soon. Your account, drafts, and memory follow you across all of them.
Stop managing content.
