Who each tool is for
Claude AI
Default
Best for: Consultants doing deep document analysis, contract review, and polished writing — especially when working across large file sets or connected to Microsoft 365 and Google Workspace.
Why pick it: A context window of up to 1M tokens (varies by model) handles entire RFPs, contracts, and research sets in one conversation. Native Microsoft 365 and Google Workspace connectors let it work where you already do, and the writing is consistently more natural and less formulaic.
Watch for: If you need to generate images, ChatGPT (DALL·E) and Gemini still have the edge — Claude doesn't produce photos or illustrations.
Writesonic
Strong Choice
Best for: Marketing consultants producing SEO-led content pipelines with AI-assisted drafting and optimization.
Why pick it: Combines writing with search-oriented optimization workflows in one product instead of separate drafting and SEO tools.
Watch for: If your process relies on deeply customized editorial workflows, standalone writing plus SEO tools may be more flexible.
