Substack audit & analytics
See what actually grows your Substack
Likes are not subscribers. Audit any public Substack profile to see which Notes, posts and publishing habits actually bring people in — no password, and nothing is ever published for you.
01Audit any profile
A score out of 100, with the fixes that matter first.
02See what actually worked
Which Notes and posts brought subscribers, not just views.
03Then reach the right readers
Opportunities, campaigns and welcome messages — you decide what gets sent.
The problem
Publishing is not the hard part. The detour is.
Every post crosses five tools. Context is re-explained each time, and the writing loses momentum.

Angle
02Engage
Reply with context, not generic comments.
Reading an article or a Note, subshack responds to what it actually argues — and mentions your work only when it fits.
- Three angles: value, reference, question
- Notes and article replies in one panel
- Multiple Note angles from a single idea
03Reuse
Your archive becomes working context.
Sync your Substack posts, then let every draft and reply pull from them under rules you define.
- Archive sync, search and tags
- Editable prompt blocks and variables
- Separate behaviour for Notes and Articles

Which Notes brought subscribers, which just got seen, and who is worth replying to.
Why we built it
The writing stays yours.
We only remove the detour.
subshack suggests, structures and remembers. It never posts, never invents your opinion, and never speaks for you.
You write. It fetches.
Grow on Substack,
without the detour.

Questions,
answered.
- Does subshack publish anything for me?
- Never a Note, an article or a restack — and it never follows, likes or subscribes for you. It only sends the messages you set up: a campaign starts when you press Start sending, and welcome messages stay drafts unless you choose to send them automatically. Every sending feature has a daily limit and can be paused.
- Does it work inside Substack?
- Yes. It uses the Substack session you are already signed in with — no sign-up, no password — and adds a panel inside Substack, next to a full dashboard: Overview, Notes, Articles, Audience, Opportunities, Campaigns, Inbox and Automations.
- What does it show that Substack does not?
- Which Notes and posts brought new subscribers, not just likes; opens and clicks as counts of people next to the rate; and your best formats and posting hours, measured against your own baseline. Every figure comes from your own account.
- Is it free?
- Yes, to start. The free plan covers one publication with its recent Notes and articles, and every sending feature has a daily limit.
- Is it a Chrome extension?
- Yes — and a Firefox add-on. Subshack (sometimes misspelled “subhack”) installs from the Chrome Web Store or Firefox Add-ons, and only appears on the Substack pages where it helps.
