Automate your Substack operations from Claude or ChatGPT

Scheduling, replies, and the analytics Substack hides, all driven by chat. Everything except the writing. Your Notes still publish when your browser is closed.

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

Run it by chat

Connect SubflowAI to Claude or ChatGPT and drive your whole publication by asking. This is the part no other Substack tool has.

Plan my week and fill my open slots. Turn my last article into 7 Notes in my voice and schedule them. Show my open rate and subscriber growth this month. Reply to everyone in my inbox. What were my best posts this quarter?

You approve everything

Nothing is scheduled, published, or replied to until you say so. The assistant proposes, you decide.

Your login never leaves your browser

Every request runs locally through your own authenticated Substack session. No password, no cookie, and none of your content on our servers.

Works with what you already use

Claude Desktop, Claude Code, Claude Cowork and ChatGPT, through SubflowAI Substack MCP. Want it running with Chrome closed? Supported.

Connect is included in Premium, or a one-time $30 add-on for any paid plan.

Sound Familiar?

Scheduling, chasing replies, digging for the numbers Substack hides. The busywork eats the hours you meant to spend writing.

Substack schedules one Note at a time. Thirty Notes across a month is thirty separate sessions.

You batch-write ten Notes on Sunday. By Friday you have posted two. The rest sit in drafts, forgotten.

There's a Better Way

Ask once, in plain English. Your assistant plans the week, writes the Notes in your voice, schedules them on Substack's own servers, and tells you what it did. Then it pulls the analytics Substack hides and works your reply inbox, all from the same conversation.

You approve. It does the rest.

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.

I am in love with this application and extension! Dheeraj did a great job putting together an easy to use, robust system for an incredibly affordable price!
