Scheduling that survives a closed laptop
Notes schedule directly on Substack's servers and publish on time whether or not Chrome is running. Batch 30 in one click, spread them across smart time slots, unschedule by range when plans change.
Automate your Substack operations from Claude or ChatGPT
Scheduling, replies, and the analytics Substack hides, all driven by chat. Everything except the writing.
★★★★★ 5.0 from real Substack writers. 5-year access for about $1.17 a month.
SubflowAI automates Substack growth from Claude and ChatGPT. It batch-schedules Notes on Substack's servers so they publish with Chrome closed, shows the analytics Substack hides, gathers replies in one inbox and writes Notes in your voice, from its Chrome extension or by chat.
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.
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.

- Done. Open SubflowAI next Sunday.
Result: 7+ Notes scheduled in 5 minutes. Zero stress for the whole week.
Why Writers Love SubflowAI
SubflowAI is the most economical and fastest way to schedule Substack Notes. Beta users consistently report it's transformed their content workflow.
The math is simple:
- Writers who post Notes consistently see 3-5x faster subscriber growth
- Missing just 5 Notes per week = 12-200 potential subscribers lost
- Over a year? That's 624-10,400 subscribers you didn't gain
SubflowAI makes consistency automatic.
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.
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.
Solid tool that does everything to help you understand your audience and grow on Substack!
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.
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!
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.
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!
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.
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!

FAQ
What do I need to run SubflowAI from Claude or ChatGPT?

Does the assistant post things without asking me?
No. Nothing is scheduled, published or replied to until you approve it. The assistant proposes and you decide.
Does Substack have native Notes scheduling?
Yes, Substack added basic one-at-a-time Notes scheduling in 2026. SubflowAI goes beyond: batch-schedule 30+ Notes in one click, AI repurposing in your Brand Voice, a visual calendar, and analytics.

No. SubflowAI v2.0 schedules Notes directly on Substack's servers. They publish even when Chrome is closed. Chrome alarm is kept as an automatic fallback for maximum reliability.
How is SubflowAI different from Substack's native scheduling?
Substack's native scheduling lets you schedule one Note at a time.

Can I use SubflowAI with Claude or ChatGPT?
Yes, with the Connect add-on. Drive SubflowAI from Claude (Desktop or Code) or ChatGPT through SubflowAI Substack MCP, our unofficial Substack connector. Ask your assistant to plan your week, draft and schedule Notes, repurpose an article, or pull your analytics, and SubflowAI runs it in your browser with your own Substack session (your login never leaves your device). Connect is a premium add-on for paid members. SubflowAI and SubflowAI Substack MCP are independent tools, not affiliated with or endorsed by Substack.
Is my Substack password stored?
No. SubflowAI uses your existing browser session. I never ask for or store your password.
How many notes can I schedule?
Unlimited. Schedule as many as you want across any time range.
Can I get a refund?
Yes. 14-day money-back guarantee. Email [email protected] for a full refund.
