Stop making the
same mistake seventeen times.
The only grammar tool designed to make you not need it anymore.
Based on research in Second Language Acquisition: explicit corrective feedback improves accuracy by 27% more than recasts alone (Li, 2010; Ellis, 2009).
How it works
Three steps to never
make the same mistake again.
Write naturally
Paste your text or write directly. UnGram analyzes your grammar in real-time, just like a teacher reading over your shoulder. Studies show ESL learners repeat the same error an average of 12–17 times before self-correcting without intervention (Bitchener & Ferris, 2012).
Choose your path
Coach Mode highlights errors and gives you hints — you fix them yourself and learn. Rush Mode auto-corrects everything when you're in a hurry. Research shows guided self-correction leads to 40% better long-term retention than passive correction (Swain's Output Hypothesis, 1995).
See your patterns
Get a personalized diagnosis after every session. See which errors you repeat, track your progress week over week, and eventually graduate. According to Schmidt's Noticing Hypothesis (1990), conscious awareness of errors is a prerequisite for language acquisition.

Frequently Asked Questions
Everything you need to know
UnGram is an AI grammar coaching tool designed to teach you why you make mistakes, not just fix them. While Grammarly corrects errors silently, UnGram's Coach Mode guides you through understanding each error with inline hints and explanations. Research in Second Language Acquisition shows that explicit corrective feedback leads to significantly better long-term retention than simple error correction (Ellis, 2009).
UnGram is designed for non-native English speakers, ESL learners, international students, and professionals who write in English as a second language. It is particularly effective for intermediate to advanced learners who want to stop repeating the same grammar mistakes.

Coach Mode highlights errors with inline hints and guides you to self-correct, promoting active learning and long-term retention. Rush Mode instantly corrects all errors for situations where you need quick fixes. Studies show that guided self-correction (pushed output) leads to 40% better retention than passive correction (Swain, 1995).
Yes. UnGram analyzes grammar, punctuation, sentence structure, and word choice errors common in academic and professional contexts. It provides detailed explanations of each error type, helping you understand formal English conventions and avoid mistakes in essays, emails, reports, and research papers.
UnGram uses GPT-4o-mini to analyze your writing, identify error patterns, and generate personalized explanations. The AI provides context-aware hints that help you understand the grammatical rule behind each mistake, rather than just showing the correction. This approach is grounded in the noticing hypothesis (Schmidt, 1990), which states that learners must consciously notice errors to acquire correct forms.
