Cross-Platform Reaction GIF Organizer That Survives Slack, Discord, iMessage, and WhatsApp's Different File Limits

desktop app weekend hack •• multiple requests

Power users have a personal stash of 50 to 200 reaction GIFs (the perfect 'NOPE', the one with the cat) that they paste into Slack, Discord, iMessage, and WhatsApp daily. Each platform has different size caps, codec quirks, and integrations, so people maintain duplicate copies in 3 chat apps' favorites and lose them when they switch jobs. They want one cloud library, hotkey access from any chat app, and auto-resize per platform.

Don't try to be the next GIPHY. The moat is the user's own taste and 200-clip personal library. Ship the macOS hotkey + auto-transcode-per-paste first, then iOS keyboard, then sync. Charge $4/month, never run an ad. The 'team shared library' upsell writes itself for offices that have spent six years inside-joking on Slack.

Public GIF discovery is a solved space (GIPHY, Tenor). The unsolved problem is *personal* reaction-GIF lifecycle: the same handful of perfect clips, instantly reachable from any chat client on any device, auto-fit to that client's quirks.

GIPHY Public catalog only. No personal-collection, no cross-platform paste shortcut, and search returns generic results, not your specific 'team inside joke' GIF.

Slack/Discord built-in favorites Each platform's favorites are siloed. A GIF you saved in Slack is invisible to Discord, iMessage, or WhatsApp.

Raycast/Alfred clipboard tools Generic clipboard managers. No GIF-specific search by mood/reaction, no auto-transcoding to per-platform size limits, no native mobile.
