What they are
ChatGPT
ChatGPT is a large language model chatbot from OpenAI that generates text, answers questions, drafts content, and reasons through complex problems in a back-and-forth conversation. Online creators use it for scripting videos, writing captions, brainstorming ideas, and repurposing content across formats. The free tier runs GPT-5.5 instant and is genuinely useful for most writing tasks, while the Plus plan unlocks GPT-4o with faster responses and image understanding. Output quality varies by prompt skill, so results often need editing before publishing.
Wordtune
Wordtune, from AI21 Labs, is an AI rewriting tool that offers multiple alternatives per sentence with tone control, surfacing sharper, more formal, or more casual versions instantly. It is favoured by ESL writers and professionals who want to sound more natural. It deliberately skips grammar checking and chat, so it covers less ground than all-in-one rivals.
