Saga vs Screenplay Assistant

Saga is a web platform for developing stories and turning ideas into videos. Its workflow spans plotting, character development, scriptwriting, storyboarding, and publishing. Writers can arrange ideas in mind maps and outlines, explore suggestions for themes, subplots, and characters, then organize scenes, shot types, and locations in a drag-and-drop storyboard. For screen stories, Saga offers customizable templates with 40 beats for films and 25 for TV. The maker lists OpenAI GPT-4o, Google Imagen 4 and Veo, Black Forest Labs FLUX, and Luma among the models powering storyboards and AI previz animations. Users can upload.txt,.fdx, or.fountain scripts; projects export as PDF and scripts as.txt or.fountain. The FAQ says users own their created content and Saga does not use it to retrain AI models. The free plan includes plot development, character archetypes, and act structure. Premium is $19.99 a month and includes full scriptwriting, an AI chatbot, storyboarding, video generation, and 40 Saga credits per month.

Screenplay Assistant turns plain prose or dictated scenes into screenplay pages in a browser, arranging material into scene headings, action, character cues, dialogue, parentheticals, and transitions. Its writing modes range from formatting that preserves the writer’s words to line editing and adding action and imagery without introducing events, characters, or conversations. Story Map supports planning, Story Lab offers craft guidance, Muse acts as a first reader, and Atticus answers in-app questions. Users can import plain text, PDF, Word, and Final Draft files and export to PDF, Final Draft, Word, or plain text. Other tools include character portraits, design sheets, storyboards, graphic novel pages, scene video, Table Read, and production reports. Writing is not capped on any plan, though project and media allowances vary. It runs on Android, iOS, macOS, web, and Windows. Spark is free forever and includes one project. Writer costs $7 a month, or $5 a month billed yearly ($60 a year).
