Turn every word you hear into knowledge you can search, share & remember. Whisper records, transcribes, and organises spoken content in 143 + languages—so meetings, lectures, interviews, podcasts, and voice memos become instantly searchable text you can revisit anytime. Why transcribe? Think 3× faster. Most people speak 120–160 wpm but type only ~40 wpm. Recording first, then skimming the transcript later lets ideas flow without the bottleneck of a keyboard. Never miss a detail. Accurate speech-to-text captures numbers, names, and action items even when you’re distracted. Search beats memory. A transcript is a living archive: type “budget” or “chapter 3” and jump to the exact second it was said. Learn smarter. Reading + listening boosts retention by up to 40 % compared with listening alone, according to cognitive-science research. Accessibility for all. Hard-of-hearing users get real-time captions; multilingual teams get same-day translations. Key Features - Real-Time Transcription – watch words appear live as you talk. - 143 + Languages & Dialects – from English and Spanish to Swahili and Marathi. - Import Anything – upload audio/video files or simply paste a YouTube link. - High-Fidelity Recording – 48 kHz capture, automatic noise filtering. - Editable, Shareable Text – correct typos, add headings, export to DOCX, PDF or SRT captions. - AI Summaries & Highlights – get concise bullet-points of the key moments. - Universal Search – find any word across your entire library in milliseconds. - One-Tap Translation – translate complete transcripts into 30 + target languages. - Private & Secure – transcripts are end-to-end encrypted; nothing is used to train external models. - Cloud Sync + Offline Mode – work anywhere, even on airplane Wi-Fi or no-service campuses. Built for every moment Meetings & Calls – automatic speaker labels keep team discussions organised. Lectures & Study Sessions – bookmark key concepts, auto-generate flash-card quizzes. Journalist & Research Interviews – time-stamped notes ready the second the conversation ends. Podcast & Video Creators – lightning-fast subtitle files and blog-post drafts. Daily Voice Memos – capture ideas on the go and search them later by keyword. How it works Record live audio or import an existing file/link. Transcribe locally first for speed, then refine in the cloud for extra accuracy. Explore: skim the AI summary, tap search to jump to any phrase, or translate with one tap. Share a clean document, caption file, or highlighted snippet—no manual editing required. Your data, your control Delete any recording permanently with a swipe. Opt-in transcription only; no “always listening.” Compliant with GDPR & CCPA standards.

Verdict

The call

The clearest difference is in-app purchases: Sound at none against Whisper's 2. Whisper's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.8.3). On price and device support there is nothing between them.
