Locus

66 mentions across 5 sources · 48% positive — mixed (weighted across 5 sources)

Hacker News, YouTube, Product Hunt, App Store, Lemmy

What users praise

What frustrates them

  • • Free tier's 3-document daily cap is tight for daily long-form readers
  • • Frequent model churn (3.5, 4o, Haiku, Flash) risks inconsistent answer quality

Praktika

65 mentions across 5 sources · 31% positive — critical (weighted across 5 sources)

Hacker News, YouTube, Product Hunt, App Store, Lemmy

What users praise

  • • Removes the social pressure of practising with a human — anxious learners talk more freely
  • • Live voice conversation on self-chosen topics feels closer to real speaking than flashcards
  • • In-dialogue corrections with one-line explanations keep the conversation moving
  • • Four named tutors and soft/balanced/strict feedback modes let you tune correction intensity

What frustrates them

  • • Billing complaints dominate: surprise annual charges after trial cancellation and refused refunds
  • • Beginner mode ignores the user's declared level and introduces unexplained vocabulary
  • • Level assessment is wildly inaccurate — a five-year Korean learner was placed at A1
  • • Tutor corrections can be wrong, including criticising words the user never said
