Claude

Anthropic's AI assistant, used by writers as a sounding board

A chat assistant from Anthropic, in a browser, on phones and through an API. Writers who use it describe the same pattern: hand over a rough list, ask what is missing, ask for the opposite case, then rewrite the answer in your own voice. Free tier, paid plans above it. Like every model of this kind it states false things with complete confidence.

    Author · Seth's Blog, published daily

    Uses AI every day for more than an hour, and says Claude is the one he actually talks to, partly because it warns him when it might be making something up. The method he describes is narrow: hand it three bullet points, ask for four more, then rewrite them himself.
