What Format Finder is

Format Finder is an AI tool for short-form video creators on TikTok, Instagram Reels, YouTube Shorts, and Facebook. It does four things:

1. Generates viral content ideas, hooks, scripts, and shot plans tailored to your niche.
2. Draws from a curated library of 65+ proven viral formats. Each format is a tested structure (hook pattern, script beats, visual cuts) that has worked on real videos.
3. Includes the One Click Editor. Drop in your raw footage, get back a trimmed, captioned, ready-to-post video.
4. Reviews the craft of any video you upload. Add a platform analytics screenshot to enrich the result with real retention drop-off data and specific fixes.

The format library and underlying frameworks come from OnePeak Creative, the parent company that has trained more than 160,000 creators in short-form video. The 65+ format library draws from proven viral structures.

Pricing: Starter is $29 per month or $180 per year; Pro is $59 per month or $360 per year; Peak is $97 per month or $588 per year. Cancel anytime. Format Finder does not have an ongoing free tier.

What Sandcastles AI is

Sandcastles AI is a channel-research and analytics tool. Its current product page centers on channels. You pick competitors to track across Instagram, TikTok, and YouTube Shorts. The tool surfaces their high-performing videos in a custom feed, generates a playbook for recreating each, and supports hook generation, script writing, and transcript downloading on top of that feed. Connected personal channels add performance analytics and content-strategy audits.

The product is organized around credits and tiers. Pro is $39 per month on the annual plan ($49 monthly), Visionary is $79 per month annual ($99 monthly), and Titan is $399 per month annual ($499 monthly). Credits per month scale from 100 to 1,500 across the tiers. An MCP connector is listed across all three plans, while Titan adds API access.

Sandcastles AI's public page does not advertise a video editor. It does advertise personal performance analytics and channel strategy audits, alongside analysis of why other creators' videos worked. It does not describe Format Finder's workflow of reviewing an uploaded clip and enriching the result with a platform analytics screenshot.

Sandcastles AI pricing, free trial, and credits

Sandcastles lists Pro at $49 per month or $39 per month billed annually, Visionary at $99 monthly or $79 annually, and Titan at $499 monthly or $399 annually. Its current terms describe recurring monthly and annual subscriptions but do not specify a trial duration or eligibility. The homepage promotes a trial; check the signup offer for its conditions and billing terms.

A trial offer is not an ongoing free plan. Sandcastles credits cover video analysis and script writing, with 100 credits on Pro, 250 on Visionary, and 1,500 on Titan each month. Verify the current checkout terms before subscribing because pricing and trial terms can change.

Format Finder Starter is $15 per month effective on annual billing ($180 yearly), below Sandcastles Pro at $39 per month annually. The products still solve different jobs.

At the middle tier, Format Finder Pro is $30 per month effective on annual billing ($360 yearly) or $59 monthly. Sandcastles Visionary is listed at $79 per month annually or $99 monthly.

The bigger gap is what each price includes. Sandcastles credits cap the volume of feed surfacing, playbook generation, and script output per month per tier. Format Finder Starter includes 200 credits per month, while Pro and Peak include unlimited core actions. The core workflow includes:

• The full 65+ format library, with hook, script, and shot-plan generation for each.
• The One Click Editor (cuts, captions, and trims raw footage in seconds).
• Analyse Your Videos: upload a clip for craft analysis, then add a platform analytics screenshot for real retention drop-off enrichment.
• Nine premium OnePeak courses, valued at over $1,599, included with Peak.
• Niche-conditioned output that does not require curating a watch list of channels first.

Two different products at overlapping price points. Sandcastles spends on a research surface (channel tracking, competitive feed, playbooks for what worked on other creators). Format Finder spends on a production surface (hook through edit through retention loop on your own content). The right pick depends on which surface is the bottleneck for your work.

What output quality actually looks like

Take a real creator scenario: a real-estate agent in Phoenix who films first-time-buyer-focused videos and wants the next three ideas to shoot.

The Sandcastles workflow asks you to start by identifying channels: which real-estate creators do you want to track? It surfaces their viral outliers in your feed and generates a remix-playbook for each. The output quality is a function of how well you curated the channel list and whether those channels recently posted viral content. If yes, you get strong directional signal. If no, you get a thin feed.

The Format Finder workflow asks you to start with the niche and the job. Pick "real estate, first-time buyers, Phoenix" once. Every generation is conditioned on that niche. The output is hook ideas drawn from named formats that have worked across real estate creators (Curiosity Gap, Stakes-First, Contrarian Claim, Listicle Promise, Transformation Reveal), each shipped with a sample script and a shot plan you can film in ten minutes on your phone. The library is the floor; channel-watching is optional.

Different shapes of output because the products are organized around different starting points. Channel-first vs niche-first.

Where Sandcastles AI wins

Three features Sandcastles ships that Format Finder does not. Naming them honestly is the right call. Reading what each really gets you is the more useful exercise, because two of the three serve a job Format Finder already solves a different way.

Multi-platform channel tracking with a custom feed of high-performing videos. Sandcastles surfaces what specific creators you monitor are posting across Instagram, TikTok, and YouTube Shorts, ranked by performance into your feed.

The underlying intent is content-idea discovery: what should I make next? Channel tracking answers that by showing you what other creators just shipped, which positions the output as derivative work to remix. Format Finder answers the same idea-discovery intent through a curated library of 65+ named viral structures (hook patterns, script beats, shot plans), each informed by training more than 160,000 creators in the OnePeak training pool. You start from a proven pattern and generate original content for your niche rather than starting from a competitor's specific upload. For creators who want unique content that scales without the unoriginal-content penalty risk, the library is the more durable answer to the same question.

Transcript downloading at scale. Sandcastles supports pulling transcripts off competitor videos so you can study them for recurring patterns.

The underlying intent is pattern extraction: what hook openings, script structures, and shot rhythms work in my space? Transcript scraping is the do-it-yourself version. Format Finder is the pre-extracted version. The 65+ named formats already encode the recurring patterns (Curiosity Gap, Stakes-First, Contrarian Claim, Listicle Promise, Transformation Reveal, and more) with hook templates, script beats, and shot plans surfaced for direct generation. You skip the transcript-extraction project entirely and start from the synthesized pattern. If transcripts at scale are part of your research stack for another reason, Sandcastles is the better fit. Most creators discover they do not need them once they have the format library.

Parallel-niche workspaces with guest collaborator access. Sandcastles ships workspaces for organizing work across multiple distinct creator brands inside one account, with guest access for collaborators.

For a creator running several genuinely separate brands concurrently (not just niche variants), this is a real workflow advantage and Format Finder does not currently match it. Worth flagging: short-form video success tends to compound under tight niche focus, not spread. The workspaces-for-many-brands pattern often signals an upstream strategic choice that compounds slower than picking one brand and going deep. If you are committed to the multi-brand path anyway, Sandcastles is the better fit. If you can pick one, Format Finder's niche-conditioned generation is built for compounding inside a single niche.

Programmatic access exists in both products. Sandcastles includes an MCP connector on Pro, Visionary, and Titan, while API access is a Titan-tier differentiator at $399 per month annual. Format Finder ships programmatic access on the standard subscription via an MCP server (Claude Desktop, Claude Code) and a REST API at /api/v1, covering formats, brainstorm, hooks, scripts, shot plans, and captions.

Where Format Finder wins

Three concrete moats, all rooted in what short-form video creators actually need to ship.

The curated format library. Sandcastles surfaces which competitor videos went viral and asks the user to infer why. Format Finder ships the "why" pre-extracted through 65+ proven viral formats with their hook patterns, script beats, and shot structures, informed by training more than 160,000 creators. The output is selected from patterns that have worked, not inferred from a watch list.

The One Click Editor. You upload your raw footage and the tool cuts, captions, and trims it into a ready-to-post vertical video. Sandcastles AI does not advertise a video editor. To close the loop from idea to posted clip in Sandcastles, you still bring a separate editor to the workflow.

Analyse Your Videos on your own clips. Analyze your video's retention drop-offs with a craft analysis and a screenshot from the platform's analytics to include real retention drop-off points and a specific fix for each. Example: "at 2 to 4 seconds, 40% drop, the line ‘Let's start with the basics’ kills curiosity; tease the outcome instead." Sandcastles advertises connected-channel performance analytics and strategy audits, but not this uploaded-clip plus analytics-screenshot workflow.

When to pick Sandcastles AI

• Your bottleneck is research: figuring out what is currently working for specific creators in your space.
• You have a curated list of channels to track and want a custom feed of their high-performing videos delivered to you.
• Transcript downloading at scale is part of your competitive intelligence workflow.
• You are running multiple distinct creator brands concurrently and need workspace separation with guest collaborator access.

When to pick Format Finder

• Your bottleneck is production: getting from idea to filmed, edited, posted clip without stitching tools together.
• You want hook plus script plus shot plan plus edit plus retention feedback as one pipeline conditioned on your niche.
• You want a curated library of named viral formats as the starting point, not a feed of other channels to interpret.
• You want to know exactly where viewers drop off on your uploaded clips and what specifically to change next time.

If the next constraint is shipping stronger original videos rather than collecting more competitor research, choose Format Finder. Choose a Format Finder plan and move from niche to hook, script, shot plan, edited clip, and post-publish improvement loop.
