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.
Free vs Pro — line by line.

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.
What's the Founder tier — and what's the catch?
A one-time payment that grants Pro for the lifetime of Vocabai. Capped at 150 spots globally — once it's gone, it's gone. It's how we're bootstrapping without VC pressure, and our way of saying thanks to the first true believers.
Is there a free trial?
There's no time-limited Pro trial, because the Free plan IS the trial — full access to Flashcards, Quiz, Matching, and a monthly taste of VocabChat. We'd rather you upgrade because you've hit a real ceiling than 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.
