The short answer. Both tools find outlier videos, posts that beat their creator's usual views, and both write scripts from them. Pick Sandcastles if you're a short-form creator who wants Kane Kallaway's scripting frameworks, a big library of curated outlier examples and a deep Claude plugin. Pick Vamos if you're a brand, agency or marketer who wants the research done for you every week, across your own posts, your competitors and your niche, and turned into next week's content in your brand's voice.

What Sandcastles does well

We'd rather tell you than have you find out later.

• Outliers measured the right way. Sandcastles scores each video against that channel's median views over the 90 days before it was posted, so a small creator's breakout shows up next to a big creator's.

• One feed for TikTok, Instagram and YouTube Shorts, from the channels you pick, plus a search across its whole database.

• Short-form craft. Every analysed video is broken into hook, hook formula, format, visual layout and transcript. Its 100+ curated Collections of formats, editing styles and visual hooks are free to browse on every plan.

• A serious Claude plugin. 16 slash commands in Claude, and the same connector in ChatGPT and Grok, with clear setup docs.

• A founder who teaches the method. Kane Kallaway's frameworks are built into the scripts, and his audience knows them.

• Cheap to try. A $5 Starter plan for new accounts.

What Vamos does differently

Vamos is your AI social media strategist. It does the doomscrolling, so you can do the creating.

• It starts with you. Add your own handle and Vamos reads your posts against your usual, then your competitors, then the niche. It tells you what worked on your account and what didn't.

• It watches the video and reads the comments. Shots, pacing, on-screen text, what's said and the music, plus up to 100 comments a post: the questions and objections your audience uses, turned into video ideas.

• It writes in your voice. My Brand holds your offer, your audience and samples of your writing. Vamos builds a voice report you can open and edit, and the next draft follows it.

• It runs again every week. Make any job a Routine and it reruns on your schedule, with results in your inbox and up to three addresses, a client's included. The Weekly brief is free on every plan.

• It reads Meta ads too. Search the Meta Ad Library by keyword, advertiser or what the ad shows, and see which ads a brand has run longest and which creators it pays.

• It's free to start. 100 credits, no card. The trial is 7 days on Pro or Business.

Side by side

Credits aren't comparable. Sandcastles charges a credit for each video it analyses or script it writes. Vamos charges per reply, by how much it reads and writes.

Which one should you pick?

Pick Sandcastles if:

• You make short-form videos yourself and want to learn hooks and storytelling from a founder who teaches them.

• You want a big library of curated outlier examples to browse.

• You mostly work inside Claude and want a deep plugin there.

Pick Vamos if:

• You run social for a brand, an ecommerce store, an app or several clients, and want next week's content planned and written, not just researched.

• Your audience's comments and your competitors' Meta ads matter to what you make next.

• You want the research to come back every week without asking again.

• You'd like to try it free before you pay.

Can you use both?

Yes. Both connect to Claude and ChatGPT, so you can call each from the same chat. Most people pick one, since both find outliers and write scripts.

FAQ

Is Vamos a Sandcastles alternative?
Yes. Both find outlier videos on TikTok, Instagram and YouTube and write scripts from them. Vamos adds your own posts, comments, Meta ads and a weekly rerun, and writes from your brand's voice report.

Does Vamos copy what competitors post?
No. Competitor posts are the research, not the template. Vamos works out why something landed, the angle, the hook, how the video is built, what people said in the comments, then applies your brand, your offer, your audience and your voice to make something that's yours. What carries over is the lesson, not the post.

Does either tool publish or edit videos?
No. Both research and write. Filming, editing and posting stay with you or the tools you already use.

Do I have to connect my social accounts?
No. You add public handles: yours, your competitors', anyone you want to follow. No login, no permissions screen.
