Alchemys vs Shai

Alchemys Storyboard is a web workspace for planning cinematic shots, generating still images and video clips, and maintaining continuity across a sequence. It can turn a project brief into a numbered shot list that users can add to a board or use to replace its current list. Shot prompts can describe camera movement, lighting, and action, with a cinematic prompting guide for refinement. A shot’s final frame can become the next shot’s opening frame, one connection at a time or across the board. Users can work in a list view or a node-based Canvas, and bring in reference images from uploads, Studio files, or connected Google Drive. Finished clips can be assembled into a film or downloaded separately. Settings include five aspect ratios and 480p, 720p, or 1080p resolution; shot duration is adjustable and defaults to five seconds. Sign-in is required, and Storyboard shares credits, model catalogue, and file library with Studio. New users receive 1,000 free credits; AI usage consumes credits based on model and workload.

Shai is an online pre-production tool for film and advertising creatives, from script breakdown and storyboards to AI video generation. Upload a script or creative document to generate a storyboard with AI-made images and production details. Shai can also extract a shot table with timing, cast, locations and other details. Users can upload their own images, edit generated outputs, and adjust the breakdown and planning. A storyboard can become a video animatic where users experiment with actions and camera movements; AI video is for premium users. Shai says it connects with different video-generation models. The free access plan covers the first nine storyboard scenes and includes 200 Shai credits for creating and editing images, with no credit card required. Shot lists can be downloaded as PDF or Excel files. Shai says uploaded material, including storylines, characters and dialogue, is not used to train its models or generate similar narrative content, and its terms say users own content created with the service. The web tool requires no local download, but the terms do not guarantee uninterrupted access.
