Find the best creators in any niche with Claude (/channels-suggest)
Hey, it's Cindy 🌱 This tool searches a curated creator database by niche, platform, size and posting rhythm, and it understands taste-level asks.
btw the waitlist for AI System Club is now open! If you're keen on using AI to automate your content, video editing, job search, business or build AI agents, feel free to sign up (only if you want to hehe). Ps. the waitlist gets first dibs:)
Get the account-specific plugin. In Sandcastles, open Settings, then Connectors, then the MCP section and download the plugin ZIP. MCP access requires an eligible paid Sandcastles plan; check the current plan before buying.
Install in Claude Desktop. Open Customize, Plugins, Add, then Upload Plugin. Upload the ZIP. In the plugin page's Connectors area, choose Install, then Add for the prefilled Sandcastles connector.
Authorize your account. Open Customize, Connectors, find Sandcastles (Custom), choose Connect and complete the Sandcastles sign-in. Confirm the connected state before trying the workflow.
Populate a small watchlist. Use /channels-add with a few creator profile URLs and confirm the returned additions. Use /videos-watchlist to fetch a small sample. Ask Claude to list which examples need /analyze, show the proposed credit cost, and wait for your approval before running those analyses. Confirm that transcripts or analysis results exist before asking for topic, hook or format patterns.
Limit permissions and test. Review the connector's tools. Keep approval enabled for paid analysis or changes until you understand the action and credit cost. Ask Claude to list the available Sandcastles tools and read a small sample from your chosen creator or watchlist.
The official Sandcastles setup documents this installation route. Start with a small watchlist and a few analyzed examples. Ask Claude to identify missing inputs and the proposed credit-using analysis before expanding the sample; an empty dataset is not evidence that a niche has no winners.
These slash commands belong to the installed Sandcastles plugin, not native Claude. If a command is unavailable, describe the same request in plain language and ask Claude to use the connected tools. If sign-in fails, check browser pop-up permissions and organization connector restrictions. Do not paste account passwords or API keys into a prompt.
the workflow
Search like a casting director
🔎 the creator search prompt
/channels-suggest Find me the best 10 channels covering [your niche, e.g. social media marketing strategy]. Instagram only, 50 to 150K followers, posting at least 15 times a month. I'm not looking for trendy people, I want deep strategy or psychology you don't typically hear. Rank them and give me each profile link. State which filters you could verify; mark missing follower or posting-frequency data instead of inventing it.
🎯 The follow-up is where it gets scary good: pick your favorite result and ask for 20 more accounts similar to them, ranked by closeness of fit, with links. One good creator becomes a whole map of the niche.
what comes back
A ranked shortlist
Available creator suggestions ranked against your criteria, with missing fields labelled unverified, with profile links you can open and judge for yourself. The filters are the point: follower band keeps you in study-able territory (big enough to prove demand, small enough that tactics transfer), and the posting-frequency floor screens out dead accounts.
💡 Pro move: review the suggestions, then use /channels-add to add your chosen creators. Rerun /topic and /hooks-watchlist when you want an updated sample. This guide does not set up an automatic weekly schedule.
