Sora Is Gone — Here Is What You Can Use Instead

On March 24, 2026, OpenAI officially discontinued Sora, its AI video generation platform. Whether you were on the free tier or paying for ChatGPT Plus to access Sora, the service is no longer available. Your existing Sora projects are inaccessible, and no timeline for a replacement has been announced by OpenAI.

This left a massive gap in the AI video space. Millions of creators, marketers, educators, and hobbyists who relied on Sora for quick AI video generation suddenly needed an alternative. ZSky AI has seen over 3,000 daily signups since the shutdown, largely from former Sora users looking for a free option that actually works.

What ZSky AI Offers for Free

1080p Resolution

Every video generated on ZSky AI renders at full 1080p resolution. This is not a downscaled preview or a watermarked draft. The free tier delivers the same resolution as paid tiers. Your videos are ready for social media, presentations, or creative projects without any upscaling needed.

Audio Generation

Unlike most AI video tools that generate silent clips, ZSky AI creates synchronized audio with your video. Background music, ambient sound, and effects are generated to match the visual content. This was one of Sora's most requested features, and ZSky AI includes it on the free tier.

30-Second Clips

Free-tier users can generate videos up to 30 seconds long. This is longer than what most competitors offer on their free plans, and it is enough for social media content, short ads, concept videos, and creative experimentation.

Unlimited Free Tier

When you sign up, you get unlimited video and image generation on the ad-supported free tier. There is no credit card required, no trial period, and no expiration. You can keep creating indefinitely.

Other Alternatives Worth Knowing About

ZSky AI is not the only option available after Sora's shutdown, but it offers the most generous free tier. Here is how the landscape looks in April 2026:

Kling AI

Kling produces high-quality video but requires a paid plan for anything beyond a limited trial. Resolution and duration are restricted on free access, and audio generation is not included.

Seedance

Seedance offers strong motion quality and has gained traction since Sora's shutdown. However, free access is limited and clips are shorter than what ZSky AI offers.

Runway Gen-3

Runway is a professional-grade tool used in film production. It does not have a free tier. Plans start at $12 per month with limited generation credits. It is an excellent tool for professionals, but not a free Sora replacement.

For users who specifically need a free AI video generator with no credit card and 1080p videos with synced audio (free-tier output includes a small ZSky wordmark), ZSky AI's free tier is unmatched in the current market.
