Reelay
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

Reelay turns one of your own videos into platform-ready copy for six networks with Meta Muse Spark, checked against platform limits and saved only after your approval. Recording a video finishes only part of a creator's publishing work. The same ideas still need different titles, descriptions, captions and tags across YouTube, TikTok, Instagram, Bluesky, Threads and Facebook, each with its own limits and measurement rules. Doing that by hand takes time, while generic AI copy loses the creator's voice, invents claims, or gets cut off mid-sentence. Reelay is a local desktop workflow with optional, explicit cloud generation. Nothing is sent until the creator ticks a consent box that starts unticked every time, and a read-only Source Snapshot shows exactly what will be sent. Every field is checked against its platform limit. If one runs over, Muse Spark rewrites it instead of truncating it. The creator reviews the drafts and applies them to the ticket editor, and nothing is saved until they click Save Changes. Existing product: the Reelay desktop app. Built November 4, 2026: the Muse Spark Repurpose Engine, consent gate and review dialog.
