FEATURES
Everything you need to automate your Notes
Schedule Notes to the Minute
Pick exact dates and times for each Note. PubQ fires them off right on schedule -- whether you're asleep, at lunch, or offline entirely.
Bank-Grade Cookie Encryption
Your Substack session cookie is encrypted with AES-256-GCM before it ever leaves your browser. PubQ never sees your password.
Undetectable Publishing
Every request to Substack is TLS-impersonated to match a real Chrome 120+ browser session. Substack sees normal browsing, not automation.
Automatic Retry on Failure
If a Note fails to publish, PubQ retries up to 3 times with exponential backoff. You get notified only if it still fails.
Cookie Expiry Alerts
PubQ monitors your session freshness and emails you before your cookie expires, so you can re-capture it in one click.
Lightweight HTMX Dashboard
No bloated JavaScript framework. The dashboard loads instantly, updates in real-time with HTMX, and works on any device.
HOW IT WORKS
Three steps. Five minutes. Done.
Install the Chrome Extension
Add the PubQ extension from the Chrome Web Store. It takes 10 seconds and requires zero configuration.
Add to Chrome →Capture Your Substack Session
Log into Substack normally. The extension detects your session cookie, encrypts it with AES-256-GCM, and securely sends it to PubQ.
Write, Schedule, Publish
Open the PubQ dashboard, write your Notes (up to 280 characters each), pick your posting times, and hit schedule. PubQ handles the rest.
A dashboard that gets out of your way
No clutter. No learning curve. Just your Notes and a schedule.

Frequently asked questions
Is this against Substack's terms of service?
PubQ uses your own authenticated session to publish Notes on your behalf -- the same way you would manually. It does not scrape, spam, or access other users' accounts. That said, use of automation tools is at your own discretion. We recommend reviewing Substack's current terms.
How does the Chrome Extension work?
The extension detects your Substack session cookie when you log in, encrypts it locally using AES-256-GCM, and sends only the encrypted cookie to PubQ's server. PubQ never sees your Substack password. The extension does not read your browsing history, modify pages, or track you in any way.
What happens when my cookie expires?
Substack session cookies typically last several hours. PubQ monitors your cookie's freshness and sends you an email alert before it expires. To refresh, just visit Substack while the extension is installed -- it re-captures automatically.
Can Substack detect that I'm using PubQ?
PubQ uses curl_cffi to generate HTTP requests with TLS fingerprints identical to Chrome 120+. From Substack's perspective, every Note PubQ publishes looks like it was posted from your normal browser session.
What's the character limit for Notes?
Substack Notes have a 280-character limit, same as the native interface. The PubQ editor shows a live character count so you never go over.
Is PubQ free?
PubQ is free during the beta period. We plan to introduce a Pro tier with additional features like analytics and multi-account support. Early waitlist members will get a discount on all paid plans.
