Score rationale: Long-form fiction and screenplay writing, not marketing copy. Free tier gives 1,000 AI credits/mo (no card) — enough to test Smart Writer but not a full manuscript. Plus at $15.83/mo annual unlocks full-length generation (10,000 credits/mo ≈ 200-300 pages). No zh/ja entry (probe: English-only site). Collaborative writing features are thinner than marketing tools — built for solo authors and co-writer pairs, not brand teams.
