PrismPoster Creator Tools

ClaudeCommunityby PrismPoster

PrismPoster Creator Tools gives Claude the exact numbers behind video and social media work, so answers about sizes, safe areas and timing come from a sourced dataset instead of memory. What you can ask: - "What size is an Instagram Reel, and where does the caption area start?" Frame size, aspect ratio and safe-area insets for 19 placements across Instagram, TikTok, YouTube, Facebook, LinkedIn and X. Each comes with the official page the figures were taken from. - "Will my logo at these coordinates be covered by the YouTube Shorts buttons?" Checks any caption, logo or button against a placement's safe area and says by how many pixels it intrudes on each side. - "My footage is 1920×1080. How do I fit it to a 9:16 Story?" Works out the aspect ratio plus a centre-crop or letterbox plan. - "What bitrate keeps a 45-second clip under 25 MB?" Calculates file size from bitrate, or the highest bitrate that fits a size cap. - "Convert these subtitles to WebVTT." Converts subtitle text between SRT and WebVTT. - "I tapped these beats. What's the tempo, and how long are 8 bars?" Estimates BPM from taps, with delay times for every note value and bar lengths. Every tool is read-only and needs no account or sign-in. It works on the numbers you give it and does not upload, store or change anything. Where a platform publishes no fixed safe area (TikTok), the tools say so and give the reason instead of a guess. The calculations are open source (MIT) at github.com/PrismPoster/creator-tools, and the placement dataset is published with a DOI. The same tools are free on prismposter.com/tools.
