You've got a backlog. A dozen old blog posts, a folder of threads that did well, a stack of Substack Notes nobody outside your subscriber list ever saw. Contentdrips promises to turn all of it into carousels in a few clicks, and it mostly does. Then you check your credit balance three weeks into the month and realize the meter is running faster than you expected, and half of what came out the other end doesn't sound like something you wrote.
That's usually the moment people start comparing Contentdrips against other options. Not because it's a bad tool. Because a credit-metered AI rewriter is one specific choice among several, and it's worth knowing what you're actually choosing between.
What Contentdrips Actually Does
Contentdrips is an AI carousel and content platform built for LinkedIn and Instagram. You feed it a topic, a block of text, a blog URL, a YouTube link, or a CSV file, and its AI writes and designs a carousel or post from it, then can publish it directly to your accounts. It runs on a credit system rather than flat feature tiers: every AI action costs a set number of credits, and different actions cost different amounts.
The credit costs aren't uniform, which matters more than it sounds like at first. Generating a carousel through the AI Carousel Maker costs 10 credits. Turning a blog post into a carousel or post costs 15 credits, the same for a YouTube video. The AI Design Agent, which builds a fully custom graphic from a plain English prompt, costs 25 credits per design. Contentdrips' own review of that feature confirms the 25-credit price directly, and a separate LinkedIn tool comparison lists the same figure independently.
Where the Credit Model Gets Expensive
The free plan gives you 50 AI credits, one time, not a monthly allowance. That's roughly three to five carousel generations before you're out, depending on which feature you use, and once they're gone you need a paid plan to keep going. It functions closer to a trial than an ongoing free tier, which is worth knowing before you build a workflow around it and then find the well runs dry two weeks in.
Starter costs $15 a month ($12 a month billed annually) and includes 500 AI credits a month, publishing to LinkedIn, and the Blog-to-Carousel and YouTube-to-Carousel features. Pro runs $26 a month ($20.83 annually) with 1,200 credits a month, unlimited brands, and unlimited team members. (Figures pulled directly from Contentdrips' pricing page and its credit cost breakdown for the AI Design Agent.)
Here's what that actually buys a solo writer, worked out in real numbers instead of abstract credit counts. Say you repurpose one blog post into a carousel and turn two older tweets into carousels each week. That's 15 credits for the blog post plus 10 credits each for the two tweets, 35 credits a week, close to 150 a month at four and a third weeks. Starter's 500 credits cover that with more than three times the room you'd actually use. The free plan's 50 one-time credits, at that same weekly pace, would run out inside two weeks, well before most people finish evaluating whether the tool fits their workflow at all.
Notes2Pic: For Repurposing Writing You Already Wrote
Notes2Pic takes a different approach to the same job. Its thread splitter is deterministic, not AI-generated: paste in a thread, a newsletter section, or a Substack Note, and it carries your own sentences onto each slide without rewriting them. If your thread is numbered (1/, 1., Tweet 1, or similar), it respects your numbering as the actual slide boundaries, one number per slide, rather than re-chopping your text by character count. If it isn't numbered, it falls back to natural paragraph breaks instead of splitting mid-sentence.
The honest tradeoff is input method. Notes2Pic doesn't fetch a blog URL or a YouTube link and generate new content from it. You paste text you already wrote, which fits the writer who's repurposing their own backlog, not someone who wants an AI to summarize a video they didn't write themselves. If your repurposing pipeline depends on turning raw video or long articles into carousels without writing anything yourself first, this isn't that tool. If your pipeline is "I already wrote this well once, now I need it as slides," it's built for exactly that.
There's no credit meter to track. The free tier gives 5 monthly credits for carousel exports plus a separate, permanent pool of 3 credits a month for turning a longer essay into a numbered thread, with a watermark on free carousel exports. Paid removes the watermark and the caps for $5 a month, or a $10 lifetime deal for the first 20 buyers (rising to $17 afterward). For the mechanics of how the splitter handles your existing writing, see how a Twitter thread becomes an Instagram carousel.
PostNitro: Wider Input Types, Still an AI Rewriter
PostNitro accepts a topic, pasted text, a general URL, or a Twitter thread link, and its AI writes new slide copy from whatever you give it, the same core approach as Contentdrips. Its free plan allows 5 downloads a month and 5 AI-generated slides per carousel, watermarked, with no scheduling. Removing the watermark requires Starter at $15 a month, but scheduling only unlocks on the $25-a-month Creator plan. (Figures from PostNitro's plans page.)
Compared to Contentdrips, PostNitro trades the credit meter for flat monthly caps on slides and downloads instead, which is easier to predict but less flexible if your repurposing volume varies week to week. Neither structure is objectively better. A credit system rewards someone whose output is lumpy, heavy some weeks and light others, since unused credits still carry into the same billing cycle. A flat slide cap rewards someone with steady, predictable output who wants to know their bill in advance without doing arithmetic on credit costs first.
BrandBird: Article URL Input, Carousels as a Newer Feature
BrandBird started as a screenshot and mockup tool and has since added an AI-assisted carousel generator that accepts a topic, pasted long-form text, or an article URL, turning it into up to 20 editable slides. The free plan lets you build and export carousels with a watermark, unlimited exports, at no cost. Removing the watermark and unlocking the AI generation step requires Pro at $15 a month. (Figures from BrandBird's pricing page.)
Because the slides are editable after generation, you can push BrandBird's output back closer to your original wording by hand, something the fully automated pipelines don't make as easy. This matters more than it sounds like if you write in a specific voice. An AI rewrite that gets the structure right but flattens your phrasing into generic LinkedIn-speak is a real cost, even when the layout looks polished. BrandBird's editable step gives you a way to claw that voice back without starting over in a separate design tool.
Comparing What Each Tool Can Actually Take as Input
The bigger practical question when repurposing content isn't just price. It's whether the tool can read the format you're starting from, and whether what comes out still sounds like you.
| Tool | Blog/article URL | YouTube URL | Thread or tweet | Keeps your original wording | Starting paid price |
|---|---|---|---|---|---|
| Contentdrips | Yes | Yes | Yes, dedicated feature | No, AI rewrites | $15/month |
| PostNitro | Generic URL only | No | Yes | No, AI rewrites | $15/month |
| BrandBird | Yes | No | No, paste as text | No, AI rewrites (editable after) | $15/month |
| Notes2Pic | No, paste only | No | Yes | Yes, deterministic | $5/month or $10 lifetime |
Contentdrips covers the widest range of source formats of the four. That's a real advantage if your repurposing pipeline includes video and blog content alongside things you've already drafted as text.
Which One Fits Your Repurposing Workflow
If your backlog includes blog posts and YouTube videos you want turned into carousels automatically, and you're comfortable tracking a credit balance, Contentdrips' Starter plan at $15 a month covers a solo writer's typical weekly volume with room to spare.
If most of what you're repurposing is writing you already produced somewhere else, a thread, a newsletter section, a Substack Note, and the point is getting your own words onto slides without an AI touching them, Notes2Pic is the more direct fit and the cheaper entry point.
If you want AI-written carousels plus native scheduling in one tool and don't mind paying for the tier that includes both, PostNitro's Creator plan at $25 a month gets you there.
If you're already inside BrandBird for other design work, its $15-a-month Pro plan adds carousels without a second subscription, with the option to hand-edit the AI's output back toward your own phrasing. None of these four is the wrong choice in general. They're built around different assumptions about where your content starts, whether that's a raw video, a topic you haven't written yet, or a thread you already finished, and the right one is whichever assumption matches how you actually work.
FAQ
Does Contentdrips have a real free plan?
Not in the ongoing sense. It gives you 50 AI credits one time, not a monthly renewal, which covers a handful of carousels before you need a paid plan.
Can any of these turn a YouTube video into a carousel?
Contentdrips does, through its YouTube-to-Carousel feature, at 15 credits per generation. Notes2Pic and BrandBird don't fetch video content directly; PostNitro's URL input isn't documented as YouTube-specific.
Which tool is cheapest if I only repurpose occasionally?
Notes2Pic's free tier has no time limit on its monthly credit reset, and PostNitro's free plan works similarly with slide and download caps. Contentdrips' 50 one-time credits are better suited to testing the tool than to ongoing occasional use.
Do I need a paid plan to remove the watermark on any of these?
Yes, across all four. Contentdrips, PostNitro, and BrandBird all require a paid tier for watermark-free exports, and Notes2Pic's watermark comes off starting at $5 a month or the $10 lifetime deal.
Start With What You've Already Written
If most of your repurposing material already exists as your own writing, a thread, a Substack Note, a newsletter you sent last month, the fastest test is pasting it directly into a splitter that won't rewrite it. For the newsletter side of that workflow specifically, see how to turn a newsletter into a thread and repurposing Substack content across platforms. If you're coming from Substack Notes specifically, turning Substack Notes into Instagram posts and how other writers repurpose Substack to Instagram cover that path in more depth.
