How to use Sayelle
A quick reference for what everything in the app does. If you're still deciding whether to download it, the homepage walkthrough is a better start. This page is for once you're using it.
Getting started
On first launch, Sayelle downloads the models it needs to run on your phone, about 4 GB in total, ideally over Wi-Fi. You don't have to sign in. Sayelle creates an anonymous account automatically so your progress can be saved. When the download finishes, pick a lesson or scenario from the roadmap to start your first conversation.
Lessons, Scenarios and Study
Lessons teach grammar through a story, one conversation at a time, on a roadmap you move along at your own pace. Scenarios put you in a real-world situation, like ordering food, shopping or getting around, with no script to follow. Study turns what you've practised into flashcards, vocabulary, listening, speaking and sentence-building exercises, so a chat you had becomes material you can revisit.
Speaking or typing
Every conversation has a text field and a microphone button. Use whichever you like, or switch partway through. Speech recognition and the tutor's spoken replies both run on your phone.
Practice energy and the free tier
Free accounts have a practice-energy allowance. Starting a new lesson or scenario, or generating a new study set, spends some energy. Resuming something already in progress costs less, and chat and your existing study sets are free. Energy recharges on its own over time, and the app shows how much you have and when it recharges next. The exact amounts can change, so check the app. Sayelle Plus removes the limit entirely (see below).
Streaks
Practising on consecutive days builds a streak, shown in the app. It's there to keep you motivated, not to lock you out. Missing a day doesn't take anything away.
Sayelle Plus
Plus gives you unlimited practice energy, unlocks every Plus lesson and scenario, and turns off ads. It's optional, and the free tier is a real, usable product on its own, not a limited demo. The price is shown in the app before you subscribe, and you can manage or cancel at any time. See Billing & Refunds.
Custom lessons and scenarios
Beyond the built-in roadmap, you can create your own lessons and scenarios around situations specific to you. This is a Plus feature. The free-tier allowance can change, so check what's available in the app instead of relying on a number here.
Search
If you know roughly what you want to practise, search across every lesson and scenario instead of scrolling the whole roadmap.
Your account and Cloud Sync
You start as a guest, and nothing is locked behind signing in. Signing in is optional, from Profile or the prompts in the app, and lets you recover your progress after a reinstall or use it on another phone. You can use Sign in with Apple (iPhone), Google (iPhone and Android), or a six-digit code sent to your email. Profile → Account Settings → Sign-in methods shows what's linked and lets you add or remove methods. Every method opens the same account, and you can't remove your last one.
If you already have an account and sign in on a device that has guest progress, Sayelle shows what each side has and asks before combining them. XP, Sparks, lessons, scenarios, study sets and chats are added together without double-counting, and the longer streak is kept. Practice energy isn't combined. If you choose not to combine, nothing changes. Merging works the same way between iPhone and Android, so you can move between them.
Signing out removes your learning data from that device and leaves it safe in your account, and signing back in restores it. Cloud Sync, also in Profile → Account Settings, controls whether your progress, chat history and resumable sessions are saved to Sayelle's backend or stay only on your device. With Cloud Sync off, the device holds the only copy, so signing out asks whether to keep or remove it. When you return to the app, it fetches progress you made on another device. The Privacy Policy has the exact details of what syncs and when.
