Which Should You Choose?
For Daily Learning: FreeTalk Dictionary
If you read English content online (news, social media, articles), FreeTalk Dictionary gives you the most consistent learning. You encounter new words naturally and learn them in context.
Why it's better than others:
- You're already browsing daily—might as well learn
- Context makes vocabulary stick better than flashcards
- Simple definitions help you think in English
- No interruption to your reading flow
For Writing: Grammarly
If you write emails, essays, or social media posts in English, Grammarly catches mistakes and teaches you correct patterns.
For Video Learning: Language Reactor
If you learn best through movies and shows, Language Reactor makes Netflix and YouTube into study tools.
Can You Use Multiple?
Yes! The best setup:
- FreeTalk Dictionary (daily vocabulary building)
- Grammarly (when writing)
- Language Reactor (weekend movie learning)
These don't overlap—each handles a different skill.
Why FreeTalk Dictionary is Essential
Even if you use other tools, FreeTalk Dictionary should be your foundation because:
Reading is everywhere: You read more than you watch videos or write. Every webpage is a learning opportunity.
Context beats flashcards: Learning words from real content you're interested in beats memorizing lists.
It's passive: You don't need to "start a lesson." Just browse normally and learn naturally.
