Sandcastles vs Octupie: Which Fits Instagram Creators? (2026)

Sandcastles and Octupie do the same core job. Each one finds the short-form videos that beat their account's usual numbers, explains why they worked, and helps you make your own version. The differences are in which platforms they cover, who picks the accounts to study, how the script gets written and what you pay.

Short version: if you publish mainly on Instagram, Octupie goes deeper on that one platform and costs less to start (the first breakdown and script are free). If you post the same videos to TikTok and YouTube Shorts, Sandcastles covers all three from one dashboard.

We make Octupie, so read this with that in mind. Prices were checked on both pricing pages on 11 October 2026.

At a glance

What is an outlier, and why do both tools use it?

An outlier is a post that did far better than its own account usually does. A reel with 400,000 views means little on an account that always gets 500,000. The same reel on an account that normally gets 20,000 is a signal: something in the hook, the topic or the format worked unusually well.

Both Sandcastles and Octupie are built on that idea, because raw view counts mostly tell you who is already big. Comparing a post with its own account's baseline tells you what worked, which is the part you can learn from. We go deeper on this, with examples from three niches, in Instagram outlier patterns by niche, and the manual version of the method is in how to track competitor Instagram accounts.

How does each tool find what's working?

Sandcastles starts from channels. You research the top accounts in your niche, it finds the top outliers, and you study why they broke out. It works across Instagram, TikTok and Shorts, which helps if you're comparing formats across platforms.

Octupie starts from you. During onboarding it learns your niche, then maps the top Instagram accounts in it without you building a list. It learns each account's normal performance and only shows posts that clearly beat it, so a small account's breakout shows up next to a big account's.

How does each tool write the script?

Sandcastles turns an outlier into a script built on the structure that made it work. Octupie builds a memory of you first: what you do, who you make content for, your positioning, your content pillars and how you write, taken from your Instagram, any other profiles you add and documents you upload. Every script starts from that memory, so the draft is written in your style from the first pass.

If most of your time with Sandcastles goes into rewriting drafts so they sound like you, that's the gap Octupie is built to close. If the drafts already work for you, it's a smaller reason to switch.

Pricing

Sandcastles (billed monthly / billed yearly):

• Pro: $49 / $39 a month, 100 credits a month
• Visionary: $99 / $79 a month, 250 credits a month
• Titan: $499 / $399 a month, 1,500 credits a month

Credits pay for analysing videos, writing scripts and running reports. Unused credits don't roll over.

Octupie (monthly / yearly):

• Free: one niche breakdown and one script in your style, no card
• Creator: $29 a month or $279 a year (INR 2,399 or INR 22,999). 15 tracked competitors, 50 video breakdowns and 30 scripts a month
• Pro: $49 a month or $469 a year (INR 3,999 or INR 37,999). 30 tracked competitors, 100 breakdowns a month, unlimited scripts under fair use

Both let you cancel anytime. Octupie offers a full refund within 14 days of any payment. See the pricing page for the current numbers.

How much does each script cost?

On Octupie's Creator plan, $29 a month buys 30 scripts, which works out to just under a dollar a script, plus 50 video breakdowns. On Pro, scripts are unlimited under fair use, so the cost per script falls the more you make.

Sandcastles works differently. Your monthly credits are shared between analysing videos, writing scripts and running reports, so the cost of a script depends on how many credits each action uses and how much research you do around it. If you mostly want scripts, check the credit cost per action on the Sandcastles site before comparing.

Either way, the number that matters more is how long you spend editing each draft before you'd film it. A cheap script you rewrite from scratch costs you an hour. Our guide to AI reel script tools that sound like you covers how to test that.

When is Sandcastles the better pick?

• You cross-post. If the same video goes to Reels, TikTok and Shorts, one tool that researches all three saves you a second subscription.
• You run several brands. Sandcastles' higher tiers include multiple workspaces and verified channels for personal analytics.
• You want an established product. Sandcastles says it is trusted by more than 100,000 creators and brands; Octupie is newer.

When is Octupie the better pick?

• Instagram is your main platform. Everything in Octupie, from the feed to the scripts, is tuned for Reels.
• You don't want to build a competitor list. The niche map is done for you.
• You want drafts in your style. Scripts start from a memory of how you write, not from a blank template.
• You want to try it first for free. No card, no trial clock to watch.
• You're in India. Octupie prices in INR for Indian creators.

How do I switch from Sandcastles to Octupie?

2. Sign up for Octupie and finish onboarding. Connect your Instagram and add any writing samples, so the memory of your style has something to learn from.
3. Use the free niche breakdown to check that the accounts Octupie mapped are the ones you'd study yourself.
4. Generate your free script and compare it with a recent Sandcastles script for the same kind of idea.
5. Only then pick a plan. If you cross-post heavily, you may keep both for a while.
