Editor's Verdict

Official Review
Mirage by Decart is not a marginal improvement on existing AI video tools — it is a different category of product entirely. The ability to transform any live video stream into any visual world in real time at broadcast-usable frame rates is genuinely new, and the practical applications for streamers, creators, and advertisers are immediate. The resolution ceiling is the only real reason to wait, and that roadmap is already public.

Pros

What we like

  • MirageLSD is the first AI video system to achieve genuinely infinite video generation without quality degradation — previous autoregressive models accumulated errors leading to rapid visual collapse, while Mirage's History Augmentation technique makes it stable across unlimited output length, which is a fundamental technical advance over all prior video AI tools
  • Under 40ms latency per frame at 20fps makes Mirage viable for live broadcast and interactive streaming applications that are completely impractical with any other current AI video model — the gap between Mirage and the next fastest alternatives exceeds 16x in response latency according to Decart's benchmarks
  • The text-prompt interface requires no technical skill to operate — users type a style description and the model applies it continuously to any video input in real time, making professional-grade AI video transformation accessible to creators without GPU hardware or video production experience

Cons

Limitations

  • Current output resolution of 768×432 is sufficient for social media and live streaming but falls short of Full HD broadcast or cinematic production standards — teams requiring 1080p or 4K output will need to wait for the roadmap updates Decart has indicated are in development
  • The model uses a limited window of recent frames for context, which can reduce long-term scene coherence for extended sessions — consistent character identity, precise object tracking, and long-term scene layout stability are listed as open challenges in Decart's own technical documentation

Not reachable, so nothing here can be bought or used. The address we listed, mirage.decart.ai, does not exist in DNS as of 7 September 2026. We resolved it three times through our own DNS and once through Cloudflare's public resolver, because one failed lookup is a network problem rather than a finding. This address also looks constructed rather than recorded: it follows the shape product-name-dot-vendor-domain, which is not where this vendor publishes. We did not establish where the current home is, and are not going to replace one guessed URL with another. Everything below this line is a record of what we had recorded, not a description of something you can go and use — and it is delisted from our free tools page for that reason.

What is Mirage by Decart?

Quick Summary

Mirage is the world's first real-time video-to-video AI model, built by Israeli AI startup Decart, that transforms any live video stream — from a webcam feed, gameplay, screen recording, or uploaded clip — into a completely new visual style using a text prompt, at under 40 milliseconds of latency per frame with zero interruption to the stream. It is designed for content creators, live streamers, game studios, filmmakers, and developers who want to apply dynamic AI-generated visual styles to video in real time rather than waiting hours for a post-production render. Mirage is available as a web platform and a mobile app, and is free to try with no hardware installation required.

Mirage is built on Decart's proprietary Live Stream Diffusion (LSD) model — an autoregressive video generation architecture that constructs each output frame individually, conditioned on a window of recent frames and a user-provided text style prompt, rather than generating fixed short clips in batch. This frame-by-frame approach is what enables true real-time transformation: as each frame is generated it is immediately fed back into the next calculation, allowing the model to respond continuously to a live input stream. The underlying MirageLSD model solves two major problems that have constrained earlier AI video tools — slow rendering speed and error accumulation during long sequences. Decart addresses error accumulation through two training techniques: Diffusion Forcing, which adds noise to individual frames teaching the model to clean up artifacts without depending on earlier frames; and History Augmentation, which fine-tunes the model on corrupted input history so it learns to anticipate and correct for drift. The result is a system that generates video infinitely without quality collapse — a first in the AI video category. Mirage currently runs at 20 frames per second at 768×432 resolution with end-to-end latency around 100 milliseconds per frame, making it viable for live streaming, video conferencing, and interactive applications. Shortcut Distillation further reduces diffusion steps from several seconds per clip to under 40 milliseconds per frame by training smaller student models to match the trajectory of larger teacher models. See related. The platform includes preset style themes — including Comic Book, K-POP, Egyptian Pyramids, and Steampunk — as well as support for custom text prompts. Users can upload a video, record directly in the app, or pipe in a live stream and apply transformations that preserve the original motion and structure while replacing the visual world entirely. Mirage is used by live streamers applying branded visual layers or alternate world skins to gameplay in real time, by content creators on TikTok and YouTube generating viral styled video without post-production pipelines, by game studios building dynamic visual overlays and alternate scene aesthetics for interactive experiences, and by advertising teams generating multiple stylized versions of a single video asset on the fly during a live broadcast. Decart, founded in 2023 by Dean Leitersdorf and Moshe Shalev — alumni of Israel's elite military intelligence Unit 8200 — also announced a strategic research partnership with the Technion–Israel Institute of Technology alongside the Mirage launch. The MirageLSD API is available on Crusoe Cloud for enterprise developers, enabling conversion of a one-minute source video into a fully stylized output in one minute. Decart puts this at up to 10x faster than alternative video AI services; the comparison is the vendor's and we have not reproduced it. Compared to stream diffusion tools and other live AI video approaches, MirageLSD produces more temporally stable output at faster response times, with previous auto-regressive models running more than 16x slower in response latency Compare alternatives.
Read the full overview
Mirage represents a genuine category breakthrough — the shift from AI video as a rendering queue to AI video as a live, responsive medium. The current practical constraints are resolution (768×432 at launch, with Full HD and 4K on the roadmap), a limited window of past frames that can reduce long-term scene coherence for very extended sessions, and the fact that high-fidelity output benefits from sufficient cloud GPU infrastructure. See related. For consumer apps, live streaming, and short-form social content, the current output quality is sufficient for TikTok-grade production. Teams building production broadcast or cinematic workflows will want to monitor the platform's roadmap for Full HD support and the upcoming facial consistency, voice control, and precise object control features Compare alternatives.
