Free tools
In-browser checks for every creative deliverable.
The same enforcement engine we use inside GoBrief briefs, broken out as free standalone tools. Your file never leaves your browser. No sign-up, no email capture.
Agency + in-house
Brand-kit compliance checker
Upload a brand guide, then drop creative. See whether colors, logo, and typography match the approved kit before you send to a client or a printer.
OpenFestivals + print
Print program PDF checker
Verify a program book PDF against real print-ready specs: CMYK, bleed, 300 DPI, font embedding, spot-color warnings. Before your printer rejects it.
OpenEvents + touring
LED loop spec validator
Drop a video, see which festival main-stage + side-stage LED rigs it passes. Dimension, duration, and aspect-ratio checks in your browser.
OpenAgency + in-house
IAB display all-sizes check
Upload one creative, preview it across every IAB standard display size with safe-zone overlays. Rejects below-spec variants before you hand them to a media buyer.
OpenMusic + podcast
LUFS + true-peak audio checker
Drop an audio file, measure integrated LUFS and true-peak against Spotify (-14), Apple (-16), podcast (-16), and broadcast (-23) targets. No upload to a server.
OpenMusic + podcast
Album + podcast cover validator
Verify square cover art against Spotify, Apple Music, Amazon, and podcast-platform specs in one pass. Size, aspect, color space, format, and file size.
OpenMusic publicists
Press-kit completeness + spec check
Drop every file in a press kit at once. We classify each, check it against its target spec, and flag what's missing. One pass, in your browser.

Every check on this page runs automatically when a partner uploads to a GoBrief brief. They see spec requirements before upload, get AI-assisted fixes for failures, and nothing off-spec ever reaches your library.
