## About Bombo

Bombo is a pronunciation trainer for iPhone and Android aimed at clear, natural American English. You say a word out loud and it scores each sound. Green marks the sounds you got right and red marks the ones to fix. You can tap any sound to hear a native speaker say it, and you get specific tips, such as where to put your tongue for "th".

The course has 24 levels and 133 short lessons. It starts with sounds like "th" and "r" and moves on to word stress, rhythm, linking and intonation. Daily practice brings back the words you struggled with on a spaced schedule, and a tricky sound stays on your list until you clear it twice. A chameleon mascot changes color as you level up.

All speech analysis runs on the phone, so recordings are never uploaded or used for training, and lessons work offline. You don't need an account. One lesson or practice session is free every day. Bombo Premium unlocks unlimited lessons on weekly, monthly or yearly plans, and the yearly plan includes a 3-day free trial.

## About VoiceBrief

VoiceBrief converts PDFs into audio that reads the original text aloud. It highlights the source text as it plays, so you can listen and keep your place in the document. If a section gets dense, you can switch to a "professor" mode that explains it in a lecture style. Besides PDFs, it takes photos, handwritten notes via OCR, and URLs.

The same document also feeds voice or text chat with an AI tutor that uses the PDF as context, AI summaries, flashcards, and quizzes at easy, medium or hard difficulty with spaced repetition. You can start playing the first section before the full MP3 is done. Your listening position syncs across devices, and you can download MP3s to listen offline. Files are private to your account unless you create a share link.

It's mainly for students, and also for professionals and researchers who get through reports and papers on their commute. The free tier gives you one saved PDF and 3 preview minutes a month, in the app only. Pro costs $9.99/month and adds unlimited PDFs, teach mode, voice chat, quizzes, flashcards and MP3 downloads.
