rtcl turns articles into personalised vocabulary practice.
Save words in context, review with spaced repetition,
and actually understand what you’re reading.
Face the words you keep meeting in the wild head-on.
What you read is up to you. rtcls are grouped by source or topic for a clean news feed.
Open an rtcl in the reader. Click to define unfamiliar words without breaking flow.
Long-pressed words land in your vocab deck in the original context, ready for review.
Definitions are useful, but usage is everything. Learn meaning AND nuance with the sentence that taught you.
Tech? Politics? Culture? Pick what you’d read anyway and watch your vocabulary grow.
Save articles for later. Great for “skim now, deep-dive later” days.
Don’t just “save” words — keep them. Review sessions stay short and focused.
Free to try. Pay when it becomes part of your daily routine.
rtcl is designed for B1+ (intermediate and above) language learners. If you’re brand new, you’ll probably want a basics-first app first.
Nope. Skim, save a few useful words, and move on. The learning happens via repetition over time.
That’s the plan — but the web app is the core product. Same account, same vocab deck.
rtcl can only show what sources allow. You’ll always have a link to the original publisher.
