Flixier is an AI video generation platform that operates directly within the editing timeline, allowing users to create video content without exporting or rebuilding elsewhere. The tool integrates AI generation capabilities seamlessly into the video editing workflow.

Key features include generating AI clips inside the editing timeline, extending shots from existing frames, connecting clips together, and exploring multiple AI models before committing to results. Users can generate from any frame, extend from the last frame, create AI transitions, and compare outputs from different AI models. The platform supports various AI video models including Kling 3.0, VEO 3.1, Sora2, Kling 2.6, and VEO 3.1 Fast, as well as AI image models like Flux 2 Pro, Nano Banana Pro, Stable Diffusion 3, GPT Image 1.5, and Imagine Art.

The platform works by allowing users to generate content directly within their editing timeline rather than treating AI generation as a separate process. This approach enables continuous building and refinement of videos without switching between different tools or applications.

Benefits include the ability to finish videos completely within one platform, eliminating the need to export and reimport content between different applications. Users can polish their videos by adding voiceovers, captions, enhancing and upscaling content, and color grading - all within the same timeline where AI generation occurs.

The tool appears targeted at video creators who need to produce finished video content efficiently. It serves users who want to leverage AI generation while maintaining control over the editing process and final output quality.
