Best for

Moonbeam

Pick Moonbeam if you write long-form content (1k+ words) and want a guided outline-to-draft workflow with style controls rather than an open chat window.

Sudowrite

Pick Sudowrite if you're writing a novel, screenplay, or long-form fiction and want AI that respects your characters and voice.

Not for

Moonbeam

Skip it if you need an API, programmatic access, or a general-purpose assistant for code, short copy, or non-writing tasks.

Sudowrite

Skip it for any non-fiction work — the UX optimisation for fiction makes it slower for everything else.
