TikTok video ideas that sell, ranked by what buyers say in the comments
Paste a store or app URL and Postspace extracts your product, audience, brand voice and conversion goal without a lengthy onboarding questionnaire.
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.
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.
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.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
