A data-driven research and scriptwriting platform for short-form video creators. Build a Watchlist of channels in your niche, deep-analyze their best-performing videos (1 credit each) to extract transcript, hook, storytelling format, visual layout, and outlier score, then turn those patterns into ideas and scripts. MCP is built in: connect https://mcp.sandcastles.ai/ to Claude Desktop or Google Antigravity, and ask it to bulk-analyze top outliers or research winning hooks and formats directly from the chat. Automations (Pro+) let rules auto-analyze videos by outlier score, views, and engagement. Pricing: a one-time $5/month Starter plan exists for new accounts only, but it is severely limited—10 credits/month, 1 workspace, no MCP, no Automations, no Reports, no new-channel tracking. Full plans: Pro $49/mo (or $39/mo annual, 100 credits, 3 workspaces, MCP), Visionary $99/mo (or $79/mo annual, 250 credits, 5 workspaces), Titan $499/mo (or $399/mo annual, 1,500 credits, 20 workspaces, API access). Note: Starter is a one-time offer and its limitations are easy to miss—full plans start at $49/mo. ScamAdviser shows a trust score of 0 but concludes the site is legit (score likely stale—not scanned in 30+ days); WHOIS is hidden and traffic is low. Not a publishing tool—research and scriptwriting only. Not to be confused with the open-source sandcastle-ai workflow engine on PyPI.

A short-form video intelligence platform with two distinct sides. The developer-facing side (dev.virlo.ai) is a pay-per-request data API and MCP server covering TikTok, YouTube Shorts, and Instagram Reels: Content Research Agents that collect videos by niche with 79 AI labels (topic, hook, format, tone, brand safety, AI use), creator/sound/hashtag lookups, tracking with daily AI reports, trends/digests, and an MCP server (https://dev.virlo.ai/api/mcp/mcp) for Claude Code and Cursor. Billing is prepaid (1 credit = $0.01, errors free); Trends Digest costs $0.25, creator lookup $0.50, agent run $0.50, raw video data $0.01. The consumer-facing side is an AI content creation tool (script/video/audio/image generation via Veo 3, Runway, Sora 2, ElevenLabs), sold via subscription tiers—but the intro subscription is data-only, and content-creation credits require an additional purchase or a higher tier (a point of complaint on Trustpilot). G2: 4.9/5 (6 reviews, all small businesses, Apr–Jun 2026); Trustpilot: mixed (two 1-star reviews about subscription not including creation credits, one 5-star review). Note: the two product lines have different pricing and access models—verify which one you\'re evaluating.

A read-only MCP server and web dashboard for demand research across Reddit, X, Hacker News, and Product Hunt. Connect it to Claude Code, Cursor, or Claude Desktop, and your agent can search discussions, find threads where people ask for a tool or complain about a product, read full comment trees, and discover subreddits with fit scores and self-promotion rules—every result carries a permalink. Agents can save post/reply drafts in your voice, but nothing posts from the terminal; every draft waits for your approval in the web app, with the same cooldowns and checks before publishing. Pricing: Free (10 requests/day, no card), Starter $9/mo (100 requests/day, 3,000/month), Pro $19/mo (unlimited requests, unlimited watches). One tool call = one request regardless of how many results it returns. Note: read-only by design—no posting, voting, replying, or DMs; dependent on Reddit/X/HN/Product Hunt APIs (availability may change); limited independent user reviews (one positive comment on StartupBase, no Trustpilot/G2 ratings as of listing).

An AI social media research platform for marketers and agencies. It reads public posts and comments across Reddit, TikTok, YouTube, Instagram, Facebook, X, and LinkedIn, tags each post across 10+ dimensions (topic, emotion, hook, intent, tone, CTA, narrative), transcribes videos and reads on-screen text/logos, then groups posts into patterns (pain points, objections, hooks) linked to the underlying posts for auditability. Pattern-matching accuracy is vendor-stated at 86–95% depending on pattern type and sample size. Offers always-on listening agents (Slack/webhook digests), on-demand research with cited reports, audience profiling (age, occupation, interests, OCEAN personality—AI-estimated, Pro+), and MCP/REST API access for Claude, ChatGPT, and Cursor. Pricing: Starter $98/mo (2,000 credits, 1 seat, no API), Pro $178/mo (5,000 credits, 3 seats, API + audience research), Business $450/mo (20,000 credits, 5 seats), Enterprise custom. Annual billing gets 2 months free; free trial available. Note: very small team (3 employees, ~8K monthly visits per Crustdata); only 2 G2 reviews (both 5-star, Jan 2026); audience demographics are AI estimates, not survey data; YouTube commenters are not profiled.

A Chrome extension for Etsy sellers that reads the public search results you\'re already viewing and turns them into market signals—competition density, price distribution, recurring visual styles and palettes, thumbnail formulas, and changes over time (Niche Radar/Visual Snaps). List & Thumb Lab generates a market-tuned listing blueprint with recommended changes, a ready-to-paste title, missing tags, and an optional improved product image. Does not connect to your Etsy account; reads only public search results. Note: it is observational market analysis, not a prediction of sales or business outcomes. Explorer €25/mo (50 credits); Operator €45/mo (150 credits); 14-day trial by application (10 credits); top-ups available.

A synthetic customer journey simulator. AI-generated shoppers (personas) walk through your funnel step by step, showing exactly where each one drops off. You can then chat with that synthetic shopper to ask why they left, what would change their mind, or how they\'d react to a new price, creative, or packaging—helping you decide which research questions are worth fielding for real. The beta personas are built from public shopper reviews (US-skewed), cover one fashion journey, and run 20 simulations per persona. Try it in the browser, no signup. Note: synthetic personas, not real customers; replies are generated. It supplements real customer research, does not replace it. Pricing not publicly listed.

A competitive intelligence and planning platform for ChatGPT Ads. Add your website to see which advertisers run ads around your market, what their creatives look like, who they target, and the buyer prompts that trigger them. The Library holds hundreds of thousands of captured ChatGPT ads with associated prompts. ContextHint identifies angles rivals leave open, turns them into ad groups with Context Hints and creative drafts, and (on Pro) tracks your buyer prompts twice a week to show whose ad appears—yours, a rival\'s, or none. Works via dashboard or a plugin inside Claude/ChatGPT. Methodology page explicitly separates observed ad records from inferred audience/intent, and does not expose competitors\' private targeting, budgets, or conversion data. Paid subscription (Research / Pro tiers); pricing not publicly displayed in supplied content.

A Safari extension for Mac-based YouTube creators that adds research and publishing tools inside YouTube and YouTube Studio—no CreatorHat login, no API key. Features include a channel-relative outlier finder (compares a video\'s views per day to the channel\'s recent normal), keyword research based on YouTube\'s own suggestions plus current competition and views-per-day of ranking videos (no invented search-volume numbers), rank checks, channel audits, and upload assist: while YouTube processes an upload, CreatorHat transcribes the video on-device via Apple Intelligence and drafts title choices and a description beside the Studio fields. Local transcripts and saved research stay on the Mac; no account system and no server. $29.99/year on the Mac App Store, no monthly plan, no separate AI bill. Note: does not guarantee more views—research signals still require editorial judgment.

An iOS App Store market research and ASO tool. Look up any iPhone app to see its chart history, ratings, and modeled monthly download and revenue estimates—each with a confidence level—then dig into the App Store searches it ranks for. Compare your app with up to five competitors via keyword gap, find niches few strong apps own, track markets and categories, and get alerts when rivals climb or drop. Data comes from App Store chart positions, ratings, prices, and search results, checked several times a day. Free to start, no card or signup to browse; Pro unlocks every app, keyword, CSV exports, and API.

An AI-powered YouTube research and competitor intelligence platform. Seed any public channel and OutlierKit scans related channels to surface “outlier” videos—content that significantly beats each channel’s normal views—helping creators spot proven topics before they saturate. Core tools include outlier research, keyword research, script/hook analysis, and single-channel analysis. Pro and Max add Competitor Studio (niche-wide maps with audience psychographics, sponsor and monetization signals) plus MCP/API access for running research inside Claude or other AI clients. Built for creators, agencies, and brands that treat YouTube as a real growth channel.
