A YouTube channel generates three kinds of writing: the script, the title and description, and the repurposed posts afterwards. Lex suits the script because it keeps a long document readable, and Rytr is the cheap workhorse for the forty titles you throw away. Copy.ai's Workflows turn one episode brief into a description and social variants in a single run, though that feature sits behind its paid plans. If you want to narrow the field further, run a side-by-side comparison between your top picks or browse the full creator software directory for options outside this category. Every listing is scored using the same review methodology.

Writesonic is an AI writing platform that combines long-form article generation, a conversational AI assistant (Chatsonic), brand voice training, and built-in SEO tools, all aimed at content marketers who need to publish more without hiring more writers. Plans start at $20/month with a limited free tier.
Lex, because a 12-minute script is a long-form document and most marketing writers choke on that length. Pro is $18/mo for unlimited AI writes and autocomplete. The free plan caps generations, which you will hit partway through a second script.
It can produce volume, which is the actual value. You want thirty candidates and your own judgement about which two are worth testing. Rytr's Unlimited plan at $7.50/mo has no generation cap, so that kind of churn costs nothing extra. Feed it the specific claim from your video rather than the topic.
Start from the transcript, not a blank page, and have the tool restructure rather than invent. Koala is the stronger option if the blog version needs to rank, since it reads the current search results before drafting. Its word-credit tiers start at $25/mo ($20/mo annually).
