Postspace

TikTok video ideas that sell, ranked by what buyers say in the comments

Website-to-brand-profile scanning

Paste a store or app URL and Postspace extracts your product, audience, brand voice and conversion goal without a lengthy onboarding questionnaire.

Buyer-comment ranking engine

Formats are scored on views, engagement, comment themes, repeatability and the share of comments showing buyer intent, and every score links back to the real TikTok videos and the date they were checked.

Film-ready creative briefs

Each matched format comes with a written hook, a shot-by-shot beat sheet, on-screen text, captions and a call to action tailored to your product.

Transparent evidence library

Every format in the library links to real TikToks you can open and verify, so you can see the comments driving the ranking rather than trusting an opaque number.

Strengths & Pros

+Ranks TikTok formats by buyer-intent comments instead of vanity views, which maps directly to revenue
+Every ranking links back to verifiable real TikTok videos, so the evidence is transparent rather than a black box
+Turns a URL into a complete, film-ready brief with hook, beat sheet, captions and CTA in minutes
+Works for both ecommerce sales goals and app-install campaigns
+Agency tier adds multi-brand workspaces, client portals and PDF export for outreach
+MCP support lets you pull briefs into Claude, Cursor and similar tools

Limitations

–Niches outside TikTok Shop ecommerce and consumer apps (B2B, local services, enterprise) get less value from the buyer-comment model
–Each scan intentionally caps at around six matched formats, which is realistic for a posting week but can feel limited for high-volume teams
–Agency tier needed for multi-brand work and client portals, adding cost for freelancers managing a few clients
–Formats and evidence are TikTok-specific, so brands not publishing on TikTok see limited direct benefit
–Free preview is intentionally shallow — full beat sheets and CTAs require starting the trial
