You write a solid Substack post every week. You know it could live on X, LinkedIn, and Instagram too, reaching people who never opened the email. So you go looking for a tool to handle that, and the search results throw a dozen options at you that all claim to do the same thing. Some of them want to connect your social accounts and post on your behalf. Some just hand you formatted content and leave publishing to you. Those are two genuinely different products wearing the same "repurposing tool" label, and picking the wrong one means either doing more manual work than you expected or handing more control to a tool than you meant to.
What "Repurposing" Actually Means for a Substack Writer
"Repurpose my newsletter" isn't one job. It's usually one of three:
- Turning a post into a thread, X or LinkedIn, text only, following the shape of your own numbered thread structure if you already write that way
- Turning a post into a visual carousel or quote card for Instagram or LinkedIn, often pulling out a single strong line as a standalone quote graphic
- Getting whatever you've made scheduled and posted across several accounts without doing it by hand each time
Most tools are strong at one of these and weak or absent on the other two. Knowing which job you actually need solved narrows the list fast, before you ever compare a single price tag.
The Real Decision: How Much Control Do You Want to Give Up?
The bigger split in this category isn't features, it's whether a tool touches your accounts at all. One group connects to X, LinkedIn, Instagram, and whatever else you use, then posts on a schedule without you clicking publish. The other group generates the content and stops there, leaving the actual posting to you.
Full automation saves real time once it's set up, and if you're already comfortable handing a tool your login credentials or API access, that time savings is legitimate. It also means a bug, a bad AI output, or an API change happens on your accounts without a human checking first. Manual export costs you a few minutes per post, and it means nothing goes out under your name that you haven't personally looked at first.
Neither approach is wrong. They're built for different comfort levels and different volumes of content. A writer posting once a week has time to review everything by hand regardless of which tool they use. A writer or small team publishing daily across five accounts feels the manual tax much faster, and automation starts looking less like a convenience and more like a requirement. Here's where four real tools actually sit on that line, based on what each one's own site currently says.
| Tool | Free tier | Paid starts at | Connects your accounts? | Publishes automatically? |
|---|---|---|---|---|
| Notes2Pic | 5 credits/month (3 as carousels), watermarked | $5/mo or $10 lifetime (first 20 buyers) | No | No, you export and post it yourself |
| Typefully | Yes, 1 social set, 15 posts/month | Roughly $8 to $16/month depending on billing | Yes, X, LinkedIn, Threads, Bluesky | Yes, on the schedule you set |
| WaveGen | Yes, 10 posts, 1 connected account | $29/month | Yes, LinkedIn, Instagram, Facebook, TikTok, YouTube, Pinterest | Yes, fully automated |
| Repurpose.io | No permanent free tier, 14-day trial | $35/month | Yes, TikTok, Instagram, YouTube, Facebook, LinkedIn, Pinterest | Yes, trigger-based automation |
Typefully's pricing has enough variation across billing cycles and plan tiers that we're giving a range rather than a single number here, socialrails' pricing breakdown puts it between $0 and $39 a month depending on tier and whether you pay monthly or annually. Worth checking Typefully's own pricing page for your specific plan before committing.
Typefully: Best for Text Threads, Not Visuals
If the "repurposing" you need is turning a Substack post into an X or LinkedIn thread and getting it published on a schedule, Typefully is built for exactly that. It writes and drafts inside the tool, previews the thread the way it'll actually look, and posts across X, LinkedIn, Threads, and Bluesky once you connect those accounts. It does not make carousels, quote cards, or any visual output. If your Substack post is going to live on Instagram as an image, Typefully isn't the tool for that half of the job.
WaveGen: Full Automation, Visual and Text, Highest Price
WaveGen sits at the automated end of the spectrum with visuals included. Paste a newsletter or blog post and it generates captions, carousel slides, and quote cards, then publishes them directly to your connected LinkedIn, Instagram, Facebook, TikTok, YouTube, and Pinterest accounts on a schedule you set. That's the most hands-off option on this list, and the price reflects it: $29 a month for 30 generated posts and 5 accounts, up from a free tier of 10 posts and one connected account.
Repurpose.io: Video-First, Not Built for Text Newsletters
Repurpose.io is the odd fit on this list for a pure-text Substack writer, and it's worth naming that clearly rather than forcing it into the comparison. It's built to take video or audio you've already published (a YouTube video, a podcast episode) and redistribute it across platforms automatically. Its Content Marketer plan runs $35 a month for up to five connected accounts per platform, with no permanent free tier, only a 14-day trial. If your Substack has an attached podcast or video component, it's a reasonable pick for that half of your output. If you're purely a writer, it's solving a problem you don't have.
Where Notes2Pic Fits (and Where It Doesn't)
Notes2Pic sits at the opposite end of the automation spectrum from WaveGen and Repurpose.io, on purpose. It never asks for your social account credentials and never posts anything for you. You paste your Substack post or Note, it splits and formats the carousel or quote card, and you download it and post it yourself, on whichever account and at whatever time you choose. Beehiiv's own guide to repurposing newsletter content recommends pulling out three to five key ideas per post to turn into separate pieces, and that's exactly the shape Notes2Pic's carousel splitting is built around, one idea or one numbered point per slide. The same splitter works whether you're starting from a full Substack post or just a single strong tweet you want expanded into a carousel, so the input doesn't have to be a full newsletter every time.
What Notes2Pic doesn't do is scheduling or auto-posting to any platform, and it doesn't touch text threads the way Typefully does. If you specifically want a Substack Note turned into an Instagram post or a newsletter turned into a numbered thread with the visual side handled and the posting left to you, that's the exact gap it fills. If you want the whole pipeline automated end to end, WaveGen or Typefully (depending on format) will get you closer to that, at a higher price and with your accounts connected.
A Realistic Weekly Workflow, Not a Single Tool
Most solo writers who've actually settled into a repurposing routine aren't using one tool for everything, they're combining two. A common pattern looks like this: paste this week's Substack post into Notes2Pic to get a carousel or quote card export, paste the same post into a text scheduler like Typefully to get the thread version drafted, review both, then post the images yourself while letting the thread go out on its scheduled time.
That split works because the two halves carry different risk. A scheduled text post going out slightly wrong is easy to delete and repost. An image with your name and face on it going out without a final look is a bigger miss. Keeping the visual step manual and letting the text step automate is a reasonable line to draw, and it's roughly how most of the broader toolkit for turning Substack, X, and Threads content into Instagram ends up getting used in practice: one tool per job, not one tool trying to do both.
Do I Need to Connect My Substack Account to Any of These Tools?
No. Every tool compared here works by pasting text or a link, not by linking your Substack account directly. The account-connection question only applies to the destination platforms (X, LinkedIn, Instagram, and so on), not to Substack itself.
Is It Safe to Let a Tool Auto-Post to My Accounts?
It depends on how the tool connects. Tools that use a platform's official API, the way most established schedulers do, are operating within that platform's rules. Tools that rely on cookie-based or session-based login instead of an official API carry more risk of the account getting flagged, since that method sits closer to what the platform's terms of service are actually trying to prevent. Before connecting any account to any automation tool, it's worth checking which method it uses, and it's a fair question to ask directly in the tool's support chat if the answer isn't stated anywhere on their site.
There's a second, quieter risk worth naming: once a tool is connected and posting on a schedule, it's easy to stop checking what actually goes out. A generated caption that drifts from your voice, or a carousel slide that misreads a line from your original post, can sit live for hours before anyone notices if nothing requires your eyes on it before it publishes. That's not a reason to avoid automation, it's a reason to build in a review step even when the tool doesn't force one on you.
What's the Cheapest Way to Repurpose Substack Content?
For visual content, Notes2Pic's free tier covers 5 credits a month with a watermark, no paid plan required to start. For text threads, Typefully's free tier covers a single social set and 15 posts a month. Neither costs anything until your volume outgrows the free limits.
Bottom Line
Start with the job you actually need done, not the tool everyone's talking about this month. If you need a Substack post turned into an X or LinkedIn thread and posted on a schedule, Typefully fits. If you want every visual and text format generated and auto-published across six platforms and you're comfortable paying $29 to $35 a month for that, WaveGen or Repurpose.io (if video's involved) fit. If what you actually want is a clean carousel or quote card from your own writing, with nothing connected to your accounts and nothing posted without your say-so, that's Notes2Pic. Most solo Substack writers end up pairing a visual tool with a scheduler rather than finding one tool that does both jobs equally well, and that's a reasonable place to land rather than a compromise.
