REX AI Tool Directory - 10+ Essential Developer Tools
Updated from the tool.rexai.top homepage (2026-02-07). All 8 tools listed below are free, ad-free, and work directly in your browser with no app download required.
Video & Social Downloaders
These three tools solve the same frustration: you find a video worth saving, but the platform either hides the download button or slaps a watermark on it. Rex cuts the process down to paste-link-and-download.
YouTube Download: Video and audio extraction, fast and stable. Paste a link to grab 4K/8K HDR video or audio-only tracks. Supports Shorts and playlists, auto-merges audio, zero ads.

Image Tools
- 16-Grid Image Splitter: Split images into 4x4 grids manually, or use AI to generate sticker packs (with daily fortune support). Tired of the standard 9-grid? Try 16, and let AI add text overlays for meme-ready results.
