02Everything Pro unlocks

What you actually get when you go Pro.

Unlimited VocabChat

Daily AI conversations that read your list, target weak words, and surface real-language patterns.

Custom AI scenarios

Describe any situation — salary negotiation, in-laws dinner, ER intake — and VocabChat plays it back.

Advanced list filters

Compose lists by CEFR, frequency, register, part of speech, and topic. Up to 50,000 words.

Unlimited lists & words

Library scales with your curiosity. No cap on lists, no cap on words per list.

All languages, all the time

Run every learning language in parallel — independent lists, mastery, and VocabChat history.

Folders & collections

Group lists by theme, level, course. Practice a whole folder as one session.

Advanced SRS controls

Tune intervals, ease factor, and review behavior. Power-user settings stay across re-subscriptions.

Richer practice variety

Pro generates 5 variations per word — definitions, examples, fill-in-the-blanks — so practice rarely feels repeated. Free pools 3.

Export to CSV / JSON

Take your vocabulary anywhere — Anki-ready, spreadsheet-friendly, backups included.

Resume past conversations

Pick a VocabChat session back up mid-stream, days later, with full context.

Streak freeze

Life happens — your streak survives. Pro gets 2 freezes per month, double the Free tier's safety net.

Priority support

Direct line to the team. Bug reports and feature requests routed first.

04Billing questions

Everything else you might ask.

  • What happens if I cancel?

    Your Pro access stays active until the end of the period you've already paid for. After that, you become a Free user — every list, word, and bit of progress stays exactly where it was. You can re-subscribe any time and resume immediately.

  • I'm in Brazil — how does payment work?

    BR pricing is shown in reais (R$) and processed locally. Card payments are supported today; PIX is on the roadmap for launch. Annual billing comes with a meaningful discount and avoids the friction of re-entering card details.

  • Can I switch between monthly and annual?

    Yes. Use Manage subscription (top of this page once you're Pro) to switch. Prorated up or down depending on direction.

  • Is there a free trial?

    Yes — every new account gets 7 days of Pro, no card needed. When it ends you keep everything you made and drop to Free; upgrade whenever you hit a real ceiling, not because a countdown ran out.

  • What if I downgrade and have 7 languages?

    Nothing is lost. Your data is archived intact — every list, every review history. Free is one active language at a time, so we'll ask you to pick which one to keep visible. Upgrade later and all 7 come back online instantly.

No card to start. Real value to stay.
