What is Atter AI?
Atter AI is an artificial intelligence transcription application that converts speech into text in real time and automatically organizes spoken content into structured meeting notes. Combining a next-generation speech recognition engine with a large language model layer, Atter AI not only transcribes audio verbatim but also produces summaries, extracts action items, identifies key decisions, and visualizes discussions as mind maps.
Unlike traditional voice-to-text tools that stop at raw transcription, Atter AI is designed to deliver outcomes, not just text. After every recording, users receive a verbatim transcript with speaker labels, an AI-generated summary, a list of action items with owners, key decisions, an auto-generated mind map, and a conversational AI assistant that can answer questions about the recording.
Atter AI is available on iOS, Android, and Apple Watch, with file import, online link transcription, and export to Word and PDF. It supports speech recognition in 90+ languages and includes real-time bilingual translation for multilingual meetings.
Why use an AI transcription app?
Manual note-taking during meetings, lectures, and interviews forces people to split attention between listening and writing. Studies suggest that handwritten notes capture less than 30% of what is actually said. An AI transcription app like Atter AI solves this in three concrete ways.
It captures everything, verbatim.
Atter uses LLM-based transcription, which corrects context errors that traditional ASR can only guess at. Benchmarked against OpenAI Whisper large-v3 on FLEURS, Atter led in all 9 languages tested (96.5% vs 95.2% average accuracy); on English LibriSpeech test-clean it reached 98.7%. Real-world accuracy varies with audio quality, accents, and overlapping speakers. Read the Atter vs Whisper benchmark →
It frees your attention.
Without the burden of writing, participants can focus on listening, asking better questions, and contributing to the discussion — the parts of a meeting that actually create value.
It turns recordings into knowledge.
Every Atter AI recording becomes searchable text that can be queried directly. Ask “What did the client actually want?” or “What deadlines did we agree on?” — and get answers in seconds.
Key features
Everything Atter AI does after you press record.
Real-time transcription in 90+ languages
Atter AI transcribes speech as it happens, with automatic language detection and mixed-language recognition within a single recording. Supported languages include English, Mandarin, Cantonese, Japanese, Korean, Spanish, French, German, Arabic, Hindi, Vietnamese, and Thai.
Speaker labels and timestamps
Atter AI distinguishes between multiple speakers, color-codes them throughout the transcript, and timestamps every segment. Tap any sentence to jump to that point in the audio.
AI summaries, action items, and decisions
Atter AI reads the full transcript and produces a structured summary with key points, action items (with owners and deadlines), and highlighted decisions — so users know exactly what to do next.
Mind map generation
Atter AI automatically visualizes complex discussions as mind maps, making it easy to understand the structure of a long conversation at a glance.
Ask-your-recording AI chat
Every Atter AI recording becomes part of a searchable knowledge base. Ask natural-language questions like “What did we agree on regarding the Q3 launch?” and get answers pulled directly from the transcript.
Real-time bilingual translation
During multilingual meetings, Atter AI translates speech in real time in both directions, helping international teams communicate without missing key context.
Core transcription use cases
Atter AI works across work, study, research, and content creation — wherever spoken conversations need to become structured, searchable text.
Business meetings and 1:1s
Atter AI joins meetings on Zoom, Google Meet, and Microsoft Teams as an automated bot, records the conversation, and delivers transcripts and summaries minutes after the meeting ends. Calendar sync with Google and Microsoft accounts means the bot can join scheduled calls automatically, so no one needs to remember to press record.
Client interviews and sales calls
Sales and account teams use Atter AI to capture every detail of customer conversations. After the call, users can query Atter directly with questions like “What objections did the prospect raise?” or “What did we commit to deliver?” — without scrubbing through audio.
Lectures and academic study
Students record lectures and seminars with Atter AI, get verbatim transcripts, and generate study-ready summaries and mind maps for exam preparation. Speaker labels make group discussions easy to review later.
User research and qualitative interviews
Researchers conducting user interviews receive speaker-separated transcripts ready for coding and analysis. Atter AI dramatically reduces the manual work of writing up sessions, freeing researchers to focus on insight generation.
Journalism and content creation
Journalists, podcasters, and YouTubers use Atter AI to transcribe interviews and long-form audio, then repurpose the content into articles, scripts, and social posts. Online link transcription makes it easy to pull text from existing media.
Voice memos and personal notes
Atter AI turns spoken thoughts into organized, searchable text — with filler words like “um” and “you know” automatically filtered out. Apple Watch support enables hands-free recording on the go.
Video transcription and online links
Atter AI transcribes audio from imported video files and from links on platforms such as YouTube, TikTok, Bilibili, X, and Instagram — without requiring users to download the file first.
Multilingual and cross-border meetings
With real-time bilingual translation in 90+ languages, Atter AI helps international teams run multilingual meetings where participants speak different native languages, with transcripts and summaries delivered in any supported language.
Who is Atter AI for?
Knowledge workers and managers
Professionals who attend back-to-back meetings and need a reliable record of decisions, commitments, and follow-ups without manually taking notes.

International teams working across languages and time zones who benefit from real-time bilingual translation and multilingual transcripts.
Multilingual transcription in 90+ languages
Atter AI supports speech recognition in over 90 languages, with automatic language detection and mixed-language recognition within a single recording.
Atter AI supports speech recognition in over 90 languages and dialects, including English, Mandarin Chinese, Cantonese, Taiwanese, Japanese, Korean, Spanish, French, German, Italian, Portuguese, Russian, Arabic, Hindi, Vietnamese, Thai, Indonesian, and Malay.
