Grammarly
Grammarly is the most widely adopted AI writing assistant, with over 40 million daily users, offering real-time grammar, spelling, clarity, and tone suggestions across browsers, Word, Google Docs, email, and more. It polishes writing without copy-pasting. Its paraphrasing and generation features are secondary to its core grammar and clarity strengths.
Swell AI
Swell AI ingests podcast episodes, YouTube videos, or audio files and generates transcripts, show notes, blog posts, social clips, and newsletters from a single upload. It targets podcasters and video creators who want to repurpose content without hiring a writer. The output quality is solid for first drafts but typically needs editing before publishing.
