Claude
A writing and reasoning assistant with a long memory
Claude is an assistant built by Anthropic for work that runs long: a full script rather than a paragraph, a spreadsheet of sponsor replies rather than one email. The free plan covers web search, file creation and memory across conversations. Pro adds more usage, unlimited projects, research and the ability to connect Slack and Google Workspace. The context window is 200k tokens on every plan, which in practice means a long transcript or a stack of documents goes in whole rather than in pieces.
Our note
The reason to choose this over the other assistants is usually the context window: work that involves a long document or a full transcript fits without being chopped up first. If your work is short prompts and quick answers, the difference will not show up and the cheaper option wins.
Grammarly
The second pair of eyes on everything you write
Grammarly catches the mistakes that get noticed in a sponsor email or a video description, and it does it inside whatever box you are typing in rather than in a separate app. The free tier covers spelling, grammar and tone. Rewriting, plagiarism detection and the larger prompt allowance sit behind Pro.
