ChatGPT

ChatGPT is OpenAI's general-purpose AI assistant. It handles writing, brainstorming, research, summarization, image generation (through DALL-E), code interpretation, file analysis, voice conversations, and Custom GPTs that can be shared with teams.

For marketers, the most-used workflows are brainstorming meeting prep, summarizing long research documents, drafting first versions of content, doing quick competitive research, and analytical tasks like cleaning up messy spreadsheets or extracting structure from raw text.

Custom GPTs are an underrated feature. You can build a specialized version of ChatGPT trained on your brand voice, content style guide, or specific repetitive tasks, then save it as a workflow you reuse rather than re-explaining context every conversation.

Freemium model with a free tier that covers most marketing tasks, plus paid subscription tiers that unlock the smartest model, longer context windows, image generation, and team features.

Best as a general-purpose AI assistant for marketing teams handling diverse tasks. The default tool to have open. For long-form writing where brand voice consistency is the priority, Claude often produces output that needs less editing.
