Features
Three strengths that keep you moving
Shadowing
AI smoothly turns your favorite audio into lessons—with automatic phrase splitting, translations, and hints. Your recordings get precise, word-level scoring plus feedback on smooth transitions. Focus on weak spots to sharpen listening and fluency.
Topic Support
Generate custom vocabulary and speech guides from any theme. Practice with AI voice chat and speak naturally—even in your native language—for instant translation and corrections. Like talking with a friend, build the confidence to speak in your own words.
Spaced Review
Send sticky phrases from topic support or AI corrections into a review queue with spaced prompts. Repeat until five correct in a row to help them stick.
Plus
Beyond study—connect with the world
Live dialogue, menu decoding, specialist documents. What you want to know right now takes shape in an instant.
From live conversation to documents—a full-featured “translation room” in one place
Control separate mics for you and your partner to show the original and translation for each utterance. Everything is saved in a chat-style thread, so you can interact smoothly—even with someone you’ve just met.
OCR translation reads menus and signs through the camera. At a restaurant, long-press a translated dish and tap “Order” to show staff a clear, purpose-built message.
PDF import translates naturally across pages. Summaries, key terms, and AI chat about the document are all supported.
From chance encounters abroad to deep study with foreign sources—whenever you want to communicate or understand, Bolstly is there as your capable partner.
Trust & Platform
A foundation you can trust
Cross-Device Sync
Keeps your library in step across iPhone and iPad. Changes sync when you open the app, join a room, or tap refresh—so you pick up where you left off. Desktop support is on the roadmap.
Privacy First
Audio files are stored encrypted on your Google Drive and on your device. They are not stored on our servers.
Offline Ready
Text translation supports an offline dictionary, so you can use translation when your connection is unreliable or you're offline.
