Grammarly vs DeepL

DeepL edges out Grammarly by 0.4 points (8.4 vs 8.0) -- a A-tier vs A-tier split that's narrow but real. Not a blowout; both belong on a shortlist. The score gap shows up most clearly in the categories that matter for DeepL's strengths, so if those categories are your priority, the lead translates.

Pricing-wise, both tools have a free tier (Grammarly starts $0, DeepL starts $0), so you can test either without committing. Compare what each free tier actually unlocks -- usage caps, model access, and feature gates differ a lot more than the headline price suggests, especially as both vendors have tightened limits in 2026.

By use case: pick Grammarly when non-native english speakers, professionals who write lots of emails, and anyone who wants a passive grammar net running in the background. Pick DeepL when professional translators working with european languages, businesses localizing content, and anyone who needs translation quality a clear step above google translate. The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap. If you're squarely in DeepL's lane, the tier-list ranking and the use-case fit point the same direction; if you're in Grammarly's lane, the score gap matters less than the fit.

Bottom line: DeepL is the safer default for most readers, but Grammarly is competitive enough that the tie-breaker is your specific workload, not the spec sheet.
