How can we help?

spelvi is in final testing and launches on iOS & Android in 2026. Join the launch list on the home page and we'll email you the moment it's live — no spam in between.

At launch spelvi ships with full dictionaries for eleven languages, each with translations, pronunciation, real example sentences and idioms, and synonyms for most of them. Grammar lessons are CEFR-graded from A1 to C2. More languages are on the roadmap.

Yes — spelvi has a free plan, and an optional Pro subscription.

Free:

• dictionary search in all eleven languages;
• the Words and Grammar courses from A1 to B2, and every study technique;
• grammar drills, including pronunciation scoring;
• books, streaming audiobooks and the news reader;
• AI helpers (explanations, word in context, stories): 5 a day;
• one AI conversation a day;
• up to 20 new saved words a day;
• the natural Spelvi voice for single words;
• progress tracking and free cloud backup.

Pro adds:

• levels C1 and C2;
• the speaking and AI-conversation steps of the courses;
• unlimited AI helpers, AI conversations and saved words;
• the natural Spelvi voice for sentences, exercises and audiobooks;
• offline use: downloadable dictionaries, audiobooks and word pictures.

You'll never lose access to words you've already saved.

Tap any word — in a lesson, a book, or the news reader — and the same rich entry appears: definition, pronunciation, part of speech, examples and a one-tap Save. No copy-paste, no switching apps. Saved words sync to every device on your account.

Speak a word or sentence and spelvi compares your audio against native models within a second or two, returning a score out of 100 plus the exact sounds to focus on. Your recording is used only to produce the score and is not stored — not on our servers, and not on your device after it has been sent.

Three things: explaining a word in the exact sentence you found it, turning your saved words into a short story for review, and unpacking why a grammar answer was wrong. It's a tutor for the moment you're stuck, not a chatbot to wander in.

Books are public-domain titles with matching audiobooks, so you can read and listen together. The news reader pulls level-appropriate articles you can tap through word by word. Everything supports one-tap lookup.

Yes. Your saved words, streaks and lesson history back up to the cloud for free and follow your account across iOS and Android. Sign in on a new device and everything is there.

Yes. For a copy of your synced data, email us from your account's address and we'll send it to you as a file. Delete your account and all synced data directly in the app from Settings → Delete account — or, without the app, request deletion by email. We don't sell your data — see our Privacy Policy for the details.

Pro is billed through the App Store or Google Play, so you manage and cancel it from your store subscriptions. Cancelling keeps Pro active until the end of the period, then returns you to the free plan with all saved words intact.
