AskSia is your AI tutor and AI study assistant. Upload lecture recordings, PDFs, slides, photos and class notes, and Sia turns them into notes, flashcards, practice tests and a study plan from your own courses. Trusted by 2M+ students at 2,000+ universities. RECORD, TRANSCRIBE AND TRANSLATE YOUR LECTURE LIVE Fast professor? Heavy accent? Tap record and read every word as it is spoken, whether the lecture is in English, Korean, Japanese, Cantonese, Mandarin or Spanish, translated into your language in real time. Recording continues when your phone is locked, a floating window keeps the transcript in view, and you can ask Sia questions mid-lecture. When the lecture ends you get a summary and an outline. Built for lectures and coursework, not meetings. 30+ languages supported. ASK SIA ANYTHING ABOUT YOUR FILES OR AUDIO Upload up to 20 files at once: PDFs, Word documents, PowerPoint decks, Excel sheets, textbook chapters, audio files, YouTube links or photos. Ask a question and get an answer with citations that point to the exact page. Long readings become summaries with key points in your professor’s terms. LECTURE IN, NOTES OUT Any recording or file can become structured notes, a study guide, flashcards or a quiz, with spaced repetition built in so the cards you miss come back until you know them. Use the flashcard maker and quiz maker on one slide deck or a whole semester. PRACTICE BEFORE IT COUNTS Build timed practice tests and mock exams from your own course material, not from random question banks, with every miss explained. Use them for midterms, finals, college entrance and grad school exams. Preparing for a standardized test? Upload your prep materials and Sia turns them into practice sets and flashcards too. SIA SHOWS THE STEPS, NOT JUST THE ANSWER Snap a photo of a problem in math, physics, chemistry, biology, statistics, coding or engineering, or type it or say it out loud. Your AI tutor works through it step by step and explains the reasoning, not just the result. Ask why, ask again, or ask in your own language. KNOW WHAT TO REVIEW BEFORE THE EXAM Sia tracks what you get wrong across notes, flashcards and practice tests and tells you what to review next, so before an exam you know exactly what needs work. BRING YOUR WHOLE SEMESTER IN ONE CLICK Install the AskSia Chrome extension, import your courses from Canvas, Blackboard, Moodle or Brightspace, and your readings, slides and deadlines sync to the app. Sia builds a study plan from your syllabus that you follow on your phone. ANY FORMAT, EVERY DEVICE Photo, text and voice input. iPhone, iPad, Mac, Windows, web and Chrome extension, with your library, notes and chat history synced everywhere. FREE TO START • 300 minutes of transcription a month • 100 PDF pages a month PREMIUM PLANS PLUS, SUPER and A+ remove the limits.

Verdict
The clearest difference is rating: Vocabulary Builder by Learning at 4.7 against AskSia's 4.1. Vocabulary Builder by Learning also leads on ratings volume (551 vs 62). AskSia's advantage is review sentiment (83% vs 68%). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Vocabulary Builder by Learning sells 11 in-app purchases, starting at $2.99 per 7 days and AskSia sells 7 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Vocabulary Builder by Learning holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Vocabulary Builder by Learning has 551 ratings behind it against 62, so its average is the more settled of the two. Written reviews complicate that: 68% of Vocabulary Builder by Learning's written reviews are positive against 83% of AskSia's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 15, 2026 and October 14, 2026 respectively.
