One underrated advantage of unified platforms is the ability to iterate quickly between modalities. Suppose you generate an image but realize the background doesn't match the mood of your video, or you write a script that's too long for the visual pacing you have in mind. In separate tools, each change forces you to go back to the beginning. In an integrated environment, you can tweak the text prompt and regenerate the visual assets without leaving the same interface. ChatGPT no login (https://overchat.ai/chat/chatgpt-free) offers exactly this kind of fluid iteration, which has dramatically accelerated my prototyping process for client pitches.
