Sandcastles is built around short-form video analysis and scripts, with substantial competitor tracking and its own MCP. Eden is for creators whose ideas move between videos, newsletters, and written posts, with research and publishing in the same workspace.
Search six platforms together. Study a LinkedIn argument, a Substack essay, or an X post alongside the videos in your niche. Different formats reveal different ways into the same topic.
Follow the unusual result. Eden scores posts against the creator's typical performance. Filter by audience size, topic, and multiplier to find ideas worth a closer look.
Study the source before adapting it. Ask Eden to examine a hook or break a video into possible post ideas. Pick the angle that connects with your own experience.
Write beyond the script. Develop that angle into a newsletter, an outline, or a short post. Keep your research board beside the draft as you work.
Both help you develop ideas. Sandcastles already analyzes videos and writes scripts. Eden's distinction is the range of source material and the work you can build from it.
Build a list worth revisiting. Group creators you want to study. Browse their work, compare what broke out, and save useful examples to your boards.
Choose the tracking capacity you need. Sandcastles Pro lists 150 competitors per workspace. Eden Starter tracks five creators and Pro tracks 25. For a large video watchlist, that difference matters.
Both can supply Claude with research. Sandcastles has an official MCP on Pro and above. Eden's MCP also works with your saved knowledge and publishing tools, subject to your plan.
Write for each audience. Develop the idea into a newsletter, a thread, or a short video. Each platform has its own tab for adjusting your copy and media.
Give it a place in your week. Eden schedules to X, LinkedIn, Threads, Instagram, TikTok, Facebook, YouTube Shorts, and Substack. Scheduling starts on Starter.
Keep your production tools. Record and edit videos in the tools you already use. Eden's YouTube publishing is for Shorts; you can still research and write long-form scripts here.
A private workspace per client. Agency Lite is $299 a month with 3 seats and 5 client workspaces, up to 10. Titan is $499 with 20. Past 10 clients, Agency has 25 workspaces and 10 seats for $999.
Build your process once. Share your Custom AIs and skills from the agency workspace, and they show up in every client.
One pool of credits for everyone. Agency Lite includes 4,500 credits a month for your team and every client, and Agency 15,000. See what each client used, and cap any one of them.
Both let clients in. Titan gives guests access to workspaces. Eden invites clients free to just the boards you pick.

Your main output is short-form video. You want detailed video breakdowns, script frameworks, and a large watchlist of competing channels.
