It will make my life and notes a lot easier especially during times with family illnesses or hospitalizations etc. So glad Finn did this. I tried earlier today and it worked!
Happy to help. You might want to research newsletters with an adjacent audience. There are quite a few focused on investing and market analysis, financial news, etc.
Perhaps engaging with those creators' posts with your aviation industry perspective might bring more attention to your newsletter?
I am new in Substack. I don’t have enough data to better understand my readers. Furthermore, am a niche product. My readers are sophisticated. My idea is to start from LinkedIn where I have a substantial base. I don’t know how to bridge.
Have you analyzed your LinkedIn audience data? You have over 8.8K followers there; perhaps you could extract some profiles and use Claude AI to summarize and segment your readers?
I have used the Playwright MCP tool ( It is a Microsoft Chrome extension) with the Claude desktop app to create some sample datasets. You could start by sampling 100 top contacts who have engaged on LinkedIn and see if that makes sense.
Once you have a good understanding of your audience and their problems, you can start offering content and solutions on Substack.
I started on Substack in the summer of 2024 (came from writing on Medium for 18 months) and analyzed my audience and content using these methods:
Hey Brinley, if your computer is closed or asleep, it won't be posting notes.
What usually happens is that when you open your laptop, the scheduled Notes will get posted as soon as the Chrome background process is running and alarms trigger.
However, I've talked to hundreds of users, and there are always exceptions: some posts may fail because the network connection is unavailable or the web session with Substack is terminated.
In the Substack Pro Studio product, I have improved error recovery: you can drag failed posts back to the scheduled column in the Kanban view, and they will be sent in the next available timeslot.
It seems to me that we have to leave the Substack Notes page open and leave the PC on, but also turn off any screen savers or power saving functions, because if the pc goes into sleep mode or something like that, and is asleep when the posting time comes around, the note will not be posted. Is this correct? Thanks in advance.
Substack's Terms of Service (https://substack.com/tos) do not permit sharing your account password; therefore, Notes Scheduler must use YOUR browser and YOUR credentials, running on YOUR computer.
This is why you need to leave your browser running and prevent your computer from going to sleep.
Hey Finn, loving the app so far. Quick question: the notes don't seem to post when my laptop is 'sleeping'. Is there something I am missing to have the note post even when I am away?
Hi Juliano, the Notes Scheduler depends on the Chrome browser running and your computer staying on to work correctly. This is stated in the product description, User Guide and documentation.
Substack terms and conditions prevent any system that would require you to disclose your credentials, so no external servers or services cannot be used for sending Notes. Therefore it must be your computer, and your browser to handle the posting in the background.
If you shutdown the browser or close your computer, Scheduler won't work. In the Gumroad product page there are instructions how to disable sleep mode on MacOS and Windows computers.
I did implement an integration with Google Sheets, but the configuration is a bit complicated, so only a small subset of users have adopted this method, see
Hey, you can download the latest version from the Gumroad email than the original—no need to repurchase it. Send me a DM if you want me to resend the Gumroad receipt email.
I have downloaded the extension and set up my first scheduled post. It shows as Scheduled but has not posted. Any thoughts? I posted at 9:15am for a 9:20AM delivery.
Hi Finn, I’ve bought the Notes Scheduler. 🙏🏻 what do you suggest users do if they have two substacks? I’m guessing we can’t toggle between submitted urls?
Hey Danusia, you can run another instance of the Notes Scheduler on Brave browser and configure that one for the other Substack newsletter. Brave browser is using Chrome engine and is compatible with the Notes Scheduler.
Finn, I've just purchased and installed the app and am already liking it. Is the hourly time I choose for a scheduled post my own time or some other time?
Changing your computer timezone settings is possible, like if you travel with a laptop to another country. Browser timezone can also be changed for testing, but that requires using Developer tools.
Can you add images to it?
Saving so I can get back to it after the holidays and back at my desk. Can't wait to try as I've been missing a scheduler, exactly as you described.
I hope you like it - as much as Kathleen, who left this awesome feedback: https://substack.com/@finntropy/note/c-79464409
Denise it is a life saver and game changer for sure 💯
Hey Finn thankyou for this insight. I'm sure this will be of much use to many
Thank you, Maurice! I hope people find this is a helpful tool.
Well Finn, Just shown this piece to a writer friend as an example of how the community comes together on Substack. Nice one Bro !!
That's precisely why I love this community. People are helping each other, and each of us is bringing something unique to the Substack community.
It will make my life and notes a lot easier especially during times with family illnesses or hospitalizations etc. So glad Finn did this. I tried earlier today and it worked!
Yes, this was something I wanted to look into for 2025 Overall Scheduling. That Finn has beaten me too it is a big bonus !!
A huge bonus!
Thanks. Do you have the same for LinkedIn? And how to leverage your LinkedIn readers to Substack?
I don't have anything for LinkedIn. My focus is 100% on Substack and Gumroad.
I have another, much improved product called Substack Pro Studio - see the User Guide https://finntropy.substack.com/p/substack-pro-studio-user-guide
There are plenty of other solutions for scheduling LinkedIn posts, such as Taplio and Buffer.
Thank you. Really valuable advice. I’ll try a few ideas. I’ll connect in case I need specific help. Thank you again.

1) https://finntropy.substack.com/p/how-to-learn-who-your-audience-is
2) https://finntropy.substack.com/p/the-investors-playbook-for-writers
I applied these lessons, and in 10 months, grew to 739 subscribers and $8K revenue while working 4 hours per week on my Substack, see this post:
3) https://finntropy.substack.com/p/how-i-turned-my-substack-posts-into
So, with your 8.8K LinkedIn followers, could you do something similar, perhaps?
This one tool has been the turning point of my success on Substack.
There is NO WAY I could post multiple times a day without this.
Thank you!
What happens if my browser tab is open to the notes page but my computer is closed/asleep?
Hey Brinley, if your computer is closed or asleep, it won't be posting notes.
What usually happens is that when you open your laptop, the scheduled Notes will get posted as soon as the Chrome background process is running and alarms trigger.
However, I've talked to hundreds of users, and there are always exceptions: some posts may fail because the network connection is unavailable or the web session with Substack is terminated.

Thank goodness thank you!
Hi Finn! Can you add images or videos to it? Can it be synced on other devices?
Image attachments work, but videos not.
Thank you for the fast reply! Can the tool be synced on another computer as well?
I did implement an integration with Google Sheets, but the configuration is a bit complicated, so only a small subset of users have adopted this method, see
https://finntropy.substack.com/p/substack-scheduled-notes-with-google
Does this also support image attachments?
No, Google Sheets integration doesn't support image attachments—just text for now.
Hiya! My 1.3.1 version isn't working. Do I need to rebuy the extension every time there's an update? Thanks!
Hey, you can download the latest version from the Gumroad email than the original—no need to repurchase it. Send me a DM if you want me to resend the Gumroad receipt email.
Hi Finn: PLEASE HELP! I bought this extension back in January (I think). I used it a couple of times, and it worked great.
However, I fell behind, and I'm ready to use it again, but I can't find the extension!
My email is pamela@pamelahilliardowens.com.
Could you help OR give me a 100% discount code so that I can use it again?
Please let me know.
Thanks so much!
Hey Pamela, I just resent the Gumroad receipt email that has the download link. Let me know if you can't find it.
Found it and re-installed it! I also saved the link and the instructions in my Apple Notes in case this happens again.
Thanks so much for the excellent Notes Scheduler App! It works like a charm.
Thanks Pamela!
I just bought this product, and I'm scheduling a bunch of notes. This is fun :)
Thanks Rodney, I love this kind of feedback.
Btw does it work if my laptop is off or asleep?
No, you need to keep your laptop running, and Chrome browser open.
Got it.
Hey Finn,
I have downloaded the extension and set up my first scheduled post. It shows as Scheduled but has not posted. Any thoughts? I posted at 9:15am for a 9:20AM delivery.
Hey Tommy, I will send you a DM so that we can troubleshoot the issue.
Hi Finn, I’ve bought the Notes Scheduler. 🙏🏻 what do you suggest users do if they have two substacks? I’m guessing we can’t toggle between submitted urls?
Help on this much appreciated!
Hey Danusia, you can run another instance of the Notes Scheduler on Brave browser and configure that one for the other Substack newsletter. Brave browser is using Chrome engine and is compatible with the Notes Scheduler.
Finn, I've just purchased and installed the app and am already liking it. Is the hourly time I choose for a scheduled post my own time or some other time?
It is on your own time by default.
Changing your computer timezone settings is possible, like if you travel with a laptop to another country. Browser timezone can also be changed for testing, but that requires using Developer tools.
Thanks, Finn.
