How to choose
Match autonomy needs first: real-time editors like Tiptap and OpenMarkdown suit iterative work while one-shot generators like MagicQuill or 18 Words fit quick drafts. Check integrations—call-joining tools and local markdown editors reduce context switching but may lack enterprise connectors. Pricing models range from free open-source to $1k/mo; test whether upvotes and community activity predict long-term maintenance. Avoid over-relying on single-format agents when your workflow spans text, slides, audio, and video.
