The Fastest Way to Schedule, Analyze, and Grow Your Substack

Batch-schedule Notes that post even when your browser is closed. See the analytics Substack hides. Run your replies from one inbox. And now, drive it all from Claude or ChatGPT.

★★★★★ 5.0 from real Substack writers. 5-year access for about $1.17 a month.

Sound Familiar?

You start strong with Substack Notes, then forget to post for days. Momentum lost.

You think of the perfect Note at 6 AM... then can't remember it by lunch.

Substack lets you schedule one Note at a time. But scheduling 30 Notes across the month? That's 30 separate sessions. There has to be a better way.

You're targeting US readers but live in Europe. 3 AM posting alarms aren't sustainable.

You batch-write 10 Notes on Sunday. By Friday, you've posted 2. The rest sit in drafts, forgotten.

Your articles take hours to write. Promoting them with Notes shouldn't take more hours.

There's a Better Way

One Sunday session. Your entire week scheduled. SubflowAI schedules Notes on Substack's servers, so they publish even when your browser is closed. Batch 30 days in 5 minutes with AI that writes in your voice. Then see the analytics Substack hides, run your replies from one inbox, and drive it all from Claude or ChatGPT. It is your Substack growth OS.

No more daily posting pressure.

What People Are Saying

SubflowAI genuinely feels like the missing piece in my Substack workflow. Being able to plan and schedule Notes weeks ahead has taken away the daily pressure to post on time. The AI repurposing is surprisingly useful and helps turn one good idea into multiple engaging Notes without feeling repetitive.

Ashutosh Tripathi Chrome Web Store Review, 5 Stars

I just click a few buttons and the extension does it for me. It also schedules each note in a smart way to fill your week. I'm amazed by this, and I know there's nothing else like it out there.

Elena Calvillo Chrome Web Store Review, 5 Stars

I love Dheeraj Sharma's new Substack Notes scheduler. It's incredibly easy to use. I haven't saved much time scheduling notes until I tried his tool. The price is insanely attractive. I highly recommend it!

Elena AI Product Leader, Substack

I'm so glad I found this app! I've only been using it for a couple of weeks but I love being able to batch and schedule my Substack notes. And they're adding functionality all the time! I tried to use the app as much as I could during the free trial and I paid for a subscription as soon as my free trial ended.

Stephanie Thurrott Chrome Web Store Review, 5 Stars

Solid tool that does everything to help you understand your audience and grow on Substack!

Ido Singer Chrome Web Store Review, 5 Stars

One of the best tools to schedule your Substack Notes. We often have a lot to say but don't necessarily have the bandwidth to post at scheduled intervals. Subflow AI gives the platform, and now it also has advanced analytics to do a full audit of your Substack Notes. 10/10 recommend!

Cash & Cache Chrome Web Store Review, 5 Stars

I was using a program that costs $30 plus a month. Couldn't believe it when I started testing Subflow. For a buck or so a month it duplicated everything on the expensive program. Tested it for 3 days and couldn't hit the purchase button fast enough. Looking forward to a long and happy partnership! Great job.

RiversZen Fitness and Health Chrome Web Store Review, 5 Stars

Subflow AI has honestly made Substack Notes so much easier for me. The batch scheduling feature is a game changer. Now I can line up weeks of content in one go and stop worrying about posting manually every day. The new Notes analytics are also really solid and give useful insights on timing, growth, and what's actually performing. I was so impressed I bought the 5-year license right away. It feels ridiculously affordable for the value.

vinayak r Chrome Web Store Review, 5 Stars

I say a little prayer for Dheeraj every time I open my content calendar and see 30+ notes already scheduled for the week. Staying consistent on Substack with multiple daily notes without a scheduling tool would be unimaginable and just chaotic. If you're looking for the best scheduling and analytics tool for Substack, this is it.
