## Featured tools

- [Audio to Text Transcriber (AI)](https://elysiatools.com/ai/en/tools/audio-to-text-transcriber.md): Transcribe speech from audio (wav/mp3/m4a/flac/ogg/webm/aac) to text, SRT, VTT or JSON using the grok-stt AI model. Up to 10 minutes.
- [NSFW Image Content Detector](https://elysiatools.com/ai/en/tools/nsfw-image-detector.md): AI content-moderation classifier using NSFWJS to flag uploaded images as safe or potentially inappropriate. Built for moderation and compliance review of your own files — it analyzes uploads only and is not an image search or discovery tool. Supports JPEG/PNG/WEBP/GIF.

- [Retro Game Texture Review and Asset Handoff](https://elysiatools.com/ai/en/hubs/retro-game-texture-review-and-asset-handoff.md): Prepare one authorized image as a low-resolution limited-color texture, compare applied candidates and deliver a reviewed PNG, palette, parameters and asset evidence for engine testing.
- [Screenshot-Based Procedure Guide Review and Handoff](https://elysiatools.com/ai/en/hubs/screenshot-based-procedure-guide-review-and-handoff.md): Turn one authorized procedure into a tested screenshot guide, verify image-to-step matching and privacy, and deliver reviewed HTML, print-to-PDF output and an editable project.
- [Responsive Page Change Review and Evidence Handoff](https://elysiatools.com/ai/en/hubs/responsive-page-change-review-and-evidence-handoff.md): Compare a page before and after a redesign at matched viewports, investigate layout and color changes, and deliver screenshots, reviewed findings and reproducible release evidence.
- [HTTP Cache Policy Change Review and Evidence Handoff](https://elysiatools.com/ai/en/hubs/http-cache-policy-change-review-and-evidence-handoff.md): Define cache test cases, compare real response headers before and after a change, review TTL budgets and deliver redacted evidence with approval and rollback conditions.
