Migration guide
Move from Substack to JustJot.ai
in five steps
Import your entire post archive from a Substack CSV export, bring your subscriber list along, and start publishing with a grounded AI co-writer and per-section paywalls — no content left behind.
How the migration works
- 1
Export your Substack archive
In Substack go to Settings → Exports → and request your data. You'll receive a ZIP that includes a posts.csv file — every published post, title, publish date, and body in one file.
- 2
Import with one click
Open JustJot.ai and paste your posts.csv into the Import tool. Every post lands as a draft node with its original title and body — ready to review, edit, or publish straight away. Up to 200 posts in a single import.
- 3
Export your Substack subscribers
From Substack Settings → Subscribers you can export a CSV of your subscriber list. Bring that into any email tool or use JustJot.ai's built-in newsletter (subscriber list is yours and exportable at any time).
- 4
Set up your paid tiers
Recreate your free / paid subscriber structure using JustJot.ai's publisher tiers. You can gate individual sections of a post instead of the whole post — a richer paywall than Substack's all-or-nothing gate.
- 5
Write your first post with AI
Draft with a grounded AI co-writer that cites sources from your own imported archive instead of hallucinating. Research, outline, write, and schedule — all in the same workspace you just migrated into.
What you gain by switching
Everything Substack does well, plus what it leaves out.
A grounded AI that cites your own archive
Substack ships no writing AI. Here, draft with an AI that searches your imported posts and attached sources before writing — answers cite the exact passage, so you build on your own work instead of starting from scratch every time.
Per-section paywalls, not all-or-nothing
Substack paywalls an entire post. JustJot.ai lets you give a free preview and cut to an upgrade at exactly the section where the premium content starts — a more flexible monetization model that typically converts better.
A feed, not just an inbox
Posts reach subscribers by email AND appear in a ranked social feed (For You + Following). Readers can follow you, quote-post your work, and discover you through the feed — distribution channels Substack only partially covers with Notes.
Your subscriber list is always portable
Download your subscriber list as a CSV anytime — including tier, join date, and segment tags. No lock-in, no permission needed. The list is yours whether you stay or leave.
AI deep research built in
Plan an issue by kicking off a multi-pass research run that produces a cited report node in your workspace — then draft from it with the AI co-writer. From research to publish in one tab.
Guest posts and co-author invites
Invite another creator to write a guest post directly in your publication space. They draft, you approve, and it publishes under your banner — a collaboration workflow Substack doesn't offer.
Common migration questions
Will I lose my post formatting?
The import reads Substack's HTML-body column and converts it to JustJot.ai's block format. Headings, paragraphs, and links transfer correctly. Images that were hosted on Substack remain linked to their Substack CDN URLs in the imported draft — you can re-upload them or leave the external links.
Do I have to redirect my old Substack URLs?
Your Substack publication stays live until you're ready to shut it down — the two run in parallel. There's no rush. Once you're happy with the new setup, you can archive or delete the old publication at your own pace.
Can I bring all 200 posts at once?
Yes. The import accepts up to 200 posts per batch. If you have more, run a second import for the older posts — each batch adds to your drafts without overwriting earlier ones.
What happens to my paid Substack subscribers?
Substack keeps its own billing. Your subscribers need to re-subscribe on JustJot.ai to be billed here — a re-subscribe email campaign to your exported list is the standard approach. You own the list, so you can reach them directly.
Is Ghost import supported too?
Yes. The same import tool accepts a Ghost JSON export (the full content export from Ghost Admin → Labs). Ghost posts land as drafts exactly like Substack posts.
What if I want to go back?
Substack's platform keeps running independently — migrating to JustJot.ai doesn't touch your Substack publication. You can run both simultaneously and switch gradually.
