Which live transcription app follows the lecture you are sitting in?

If the talk is in a language you already read, the free apps are hard to beat. Google Live Transcribe is preinstalled on Pixel and select other Android phones, Apple Live Captions is a setting on iPhone 11 or later, and both describe what they do as transcription rather than translation. If the speaker's language is not yours the field narrows quickly: Google Translate's Transcribe mode covers eight languages, Apple's spoken translation covers twelve language entries in Phone and FaceTime, Microsoft retired its multi-device conversation feature in June 2026, and Notta caps live translation at two or four uses a month on every plan it sells. Koine Live Pro, USD 24.99 a month, is built for that narrower case: translation into your language while the speaker is still talking, in up to 70 languages, kept in a private history you can ask questions about afterwards.

What each one publishes.

Every figure below is what the vendor states on its own help pages, store listings and legal pages, checked on 17 September 2026.

What Google Live Transcribe Apple Live Captions & Translate Microsoft Translator Koine Live Pro
What it is A free Android accessibility app, Android 12 and up, which Google says is already installed on Pixel phones and select other Android phones. It captures speech and sound and shows them as text on screen. Two built-in features. Live Captions is an accessibility setting on iPhone 11 or later giving "a real-time transcription of spoken audio" in any app or the room around you. Live Translation is separate, in the Translate app, Messages, Phone and FaceTime. A free consumer app on iOS and Android: "Translate text, speech, and images in over 100 languages - for free." Microsoft retired the multi-device conversation feature in late June 2026; there is no retirement notice for the app itself. The personal side of the Koine app on iPhone and Android. You point your own phone at the lecture, meeting or talk you are attending and read it live, translated if you want.
Live translation, or transcription only Transcription, as Google describes it. The help page offers a primary and an optional secondary language for transcription, not translation, and the only translation published for the app turns American Sign Language into English text through the front camera. Spoken translation lives in Google's separate Translate app. Apple describes Live Captions as transcription only. Translated speech is the separate Live Translation feature, which Apple says lets you "hear and read the spoken and text translation in your preferred language" during a call, and which is "available for one-on-one calls". Yes, on one device. "Real-time speech translation" on both store listings. What remains after June 2026 is "Speak two languages into one microphone for one-on-one conversations" in a split-screen view. Yes. The translation arrives in your language as the speaker talks, about a second and a half behind. Up to 3 languages in a session, from 70.
Languages as published Over 80 languages and dialects on the Play listing, updated 17 August 2026. Google's Accessibility Help page publishes a different count for the same app, over 70; both pages are linked below. 18 language and region entries for Live Captions, which Apple says "isn't available in all languages, countries, or regions". Live Translation is narrower where it is spoken: 21 entries in the Translate app, 12 in Phone and FaceTime, 11 with AirPods. Counted from Microsoft's table, 48 of 136 rows carry speech and 135 carry text. The store listings say "Translate text in 100+ languages". 70 languages, 57 of them with translated voice. Up to 3 in one session.
Price and free tier Free. The Play listing shows no in-app purchases. A maximum session length is not advertised. No price is published for Live Captions; it is an accessibility setting on a supported device. The Translate app is listed as free. Live Translation needs an Apple Intelligence iPhone 15 Pro or later, and Apple's footnote says expanded access to server-model features "will be available for a fee in the future". Free, with no paid tier. The App Store listing shows the price as free with no in-app purchases row. USD 24.99 a month for 4 language-hours, plus hour packs that never expire. Transcribing without translating uses a third of an hour per hour, so the month covers about twelve hours of transcript or four hours translated into one language. No free tier; Koine Plus is included.
What is kept afterwards, and export History for up to three days, or 24 hours with history off, and not saved by default. Settings offers Export all stored transcription, plus select all and copy; no file format is named. You can search within a transcription. Very little, and only for calls. The 1 Minute setting keeps captions during the call and blocks copy, screenshot and screen recording; 1 Hour keeps them for an hour afterwards and allows those. No session library and no file export is published. In Translate, Favorites sync across your devices. —. Microsoft publishes nothing about saved sessions, transcripts, search or export. The only persistence described is pinned translations and a starred phrasebook. The transcript, your highlights, notes and photos, and the audio only if you switched recording on. A private history you can search across every session.
Questions or summaries over past sessions —. No summarising or question-answering feature appears in Google's material for this app. —. Apple publishes none for Live Captions or Translate. A recorded phone call can be summarised in Notes with Apple Intelligence, but Apple states call recording "isn't currently available in" the European Union among other regions. —. No summarising or question-answering is published for the consumer app. Yes, through Koine Plus, which Live Pro includes: questions, summaries, study cards and review audio, grounded in the transcript.
Where the audio is processed, and data location In the cloud, with an on-device gate. Google's research post describes the app as powered by Google Cloud, with an on-device speech detector deciding when to open the connection. The help page says audio and transcriptions are encrypted and temporarily stored in the app. A data location is not advertised. On the device. Apple: Live Captions are "generated on device"; on Mac, "Audio is processed on device"; Live Translation "runs entirely on device". In the Translate app on-device is a setting, and when both languages are not downloaded Apple stores transcripts of audio interactions for two years and may review a subset. In the cloud, and recorded. Microsoft's confidentiality page names the free consumer apps as the exception to its no-trace promise: voice clips and text translations are recorded for service improvement, employees and vendors "will be able to review your voice clips", and clips are kept up to two years. EU residency for the consumer app is not advertised. In the cloud. Live audio is relayed through servers in Amsterdam and accounts are stored in Stockholm. OpenAI's speech and translation runs outside the EU today, and EU processing for it is scheduled.
Offline On supported devices. Google says to be connected unless you use a downloaded offline language: multiple languages on Pixel and select devices on Android 12 and up, English only on Android 8 to 11. No offline language count is published. Yes for translation, with downloaded languages: "Download languages to translate entirely on your iPhone, even without an internet connection." On Mac, Live Captions downloads its language data on first use and needs a connection for that; for iPhone and iPad Apple publishes no network statement. Text and camera only. "Speech translation feature works only while online." Offline text packs and an always-offline phrasebook of over 200 phrases are published; no pack count is given. Needs a connection while it runs.
Sharing live Not advertised beyond one device. On a foldable, Dual Screen mode shows the transcript on the inner and outer screens so both people can read it. —. Apple describes no way to share a session with other people's devices, and states that Live Translation in Phone and FaceTime is "available for one-on-one calls". Retired. Joining a live translated conversation by code or QR belonged to the multi-device conversation feature Microsoft retired in June 2026, and the browser join page no longer serves a join interface. Microsoft's own marketing pages still advertise the feature. Share a session with up to 50 listeners, who join in the browser with no account.
Where it wins Free, no account, already on the phone and reachable from the accessibility button, Quick Settings or a two-finger swipe. Over 80 languages and dialects. Built with Gallaudet University, with external microphone support, custom words for names and terms, and sign language to text. No price, no account, and the processing stays on the device. It captions any app or the room around you, translation works offline with downloaded languages, and it is built into Messages, Phone and FaceTime with nothing to install. Free with no paid tier at all. Counted from the same table, 135 of 136 rows carry text, 39 carry image translation and 69 text-to-speech. Offline text packs and an always-offline phrasebook. Translation while the speaker is still talking, in 70 languages. A private history with questions and summaries. Recording off by default. A podcast episode link works the same way as a room. EU hosting for the relay and the account.

Two more worth knowing

Notta is a cloud notetaker with genuine live translation on web and mobile, and the thing to check is the counter rather than the price. Its help centre states that monolingual real-time translation is "Available on all plans" with a "Usage Limit: 2 free uses per month", and bilingual transcription and translation with four; the pricing page repeats those caps for Free, Pro, Business and Enterprise alike, and lifting them needs a paid plan plus a paid add-on. In US dollars on 17 September 2026 the plans are Free at USD 0, with 120 transcription minutes a month, three minutes per conversation and no export; Pro at USD 8.17 a month billed annually; Business at USD 16.67. Notta advertises "98%+ Accuracy Guaranteed" on its homepage while its own help centre publishes 90% or higher for formal meetings and around 50% to 80% for casual ones. Data sits in Amazon Web Services in Tokyo, with no EU residency option published, and the mobile app cannot transcribe offline at all. Otter, the other notetaker people ask about here, has its own page: Koine Live Pro vs Otter.

Plaud is the hardware answer: a small recorder, a card or a pin, at USD 159 for the Note and USD 189 for the Note Pro, with a subscription that starts free at 300 transcription minutes a month and runs to USD 17.99 a month for Pro and USD 29.99 for Unlimited. It transcribes 112 or more languages, one per recording, on its own microphone and its own storage. For the room you are sitting in it is the wrong shape, and Plaud says so itself: "No, Plaud does not support real-time transcription", and "No - Plaud doesn't currently support translation between languages." Nothing is readable while the talk is happening. What it does well is everything after, and its data handling is documented in detail: EU and EEA accounts sit in Amazon Web Services in Frankfurt, with ISO 27001, ISO 27701 and SOC 2 Type II published. Both checked 17 September 2026.

When one of these is the better choice

For most people in most rooms the free option is the right one, and it is already on the phone. If the lecture is in a language you read, Google Live Transcribe or Apple Live Captions puts the words on screen for nothing, with no account and no subscription. Live Transcribe in particular carries what an accessibility team builds and a notetaking app does not: external microphone support, custom words for names and terms, a vibration when your name is spoken, labels for non-speech sounds, and sign language to text.

If you need translation rather than transcription, try Google Translate's Transcribe mode before paying for anything. Google describes it as translating one person speaking at length in near real time, and its Play listing itemises it at eight languages, named in Google's launch post as English, French, German, Hindi, Portuguese, Russian, Spanish and Thai, in any combination. Google publishes 73 for its bilingual live translate mode, so eight is narrow. But if your lecture is in one of the eight it costs nothing, and Google is straight about the conditions: a quiet room, one person speaking at a time.

Privacy is the second reason to choose a free one, and Apple's material is explicit about it: Live Captions are "generated on device", Live Translation "runs entirely on device", and with languages downloaded the Translate app works with no connection at all. If your requirement is that the audio never leaves the phone, Apple's material says something Koine's cannot, because Koine translates on its servers. The counterpart, in Apple's own words: when both languages are not downloaded the work moves to Apple's servers and transcripts are kept for two years, a subset reviewed.

When Koine Live Pro is

Koine Live Pro exists for the case the free apps do not cover: the speaker's language is not yours, the talk runs for an hour, and you want to follow it now rather than read a translation tonight. The translation arrives in your language while the sentence is still being finished, about a second and a half behind, in up to 70 languages and up to three at a time. You can leave it in the original to practise and switch when you lose the thread.

What happens afterwards is the other half. Every session lands in a private history with your highlights, notes and photos, and Koine Plus, which Live Pro includes, answers questions about what was said, writes summaries and makes study cards from it. None of the four products in the table publishes anything like that; Notta and Plaud do.

Two smaller things follow. Recording is a separate switch, off by default, so a session can keep the words and no audio, which matters in a classroom or a church. The relay and the account live in the EU, in Amsterdam and Stockholm, with OpenAI's speech and translation the one part still running outside the EU today and EU processing scheduled.

What the table cannot show

We rate nobody's accuracy here, our own included. Google, Apple and Microsoft publish no accuracy figure for these products at all. The only test worth anything is ten minutes of your own lecturer, in your own room, from the seat you actually sit in.

All of this is machine transcription and machine translation, and all of it is wrong sometimes. Apple states that Live Captions "shouldn't be relied upon in high-risk or emergency situations" and that Live Translation "uses generative models, and outputs may be inaccurate". Koine's own note says the same in plainer words: a tool for following and remembering, not professional interpreting or transcription, and not to be relied on where the consequences are medical, legal or contractual.

Two practical things no table holds. Apple notes that "Live Captions uses additional battery", and anything that listens for ninety minutes will drain a phone, so a charger belongs in the bag; a clip-on microphone helps in a large hall, whichever app you use. And the consent is yours, not the app's. Tell the room you are transcribing before you start.

Questions

Common questions.

Does Google Live Transcribe translate a lecture into my language?

Not as Google describes it. The help page offers a primary and an optional secondary language for transcription, and the only translation Google publishes for the app turns American Sign Language into English text through the front camera. Spoken translation lives in Google's separate Translate app, whose Transcribe mode covers eight languages.

Are Apple Live Captions and Apple Translate the same thing?

No. Live Captions is an accessibility setting that transcribes what it hears into the same language, on iPhone 11 or later, across 18 language and region entries. Live Translation is a separate Apple Intelligence feature in the Translate app, Messages, Phone and FaceTime; it needs an iPhone 15 Pro or later and covers 12 entries in Phone and FaceTime and 11 with AirPods.

Can several people still join one Microsoft Translator conversation?

Not by any method Microsoft currently publishes. It retired the multi-device conversation feature in late June 2026, named no replacement, and its browser join page no longer serves a join interface. Some Microsoft marketing pages still describe the feature, so check the app rather than the marketing. What remains is one phone with a split screen for a one-on-one conversation.

Which of these work without a connection?

Apple's, with downloaded languages, which Apple states plainly. Google Live Transcribe has offline languages on Pixel and select Android 12 devices, English only on Android 8 to 11. Microsoft's offline packs cover text and camera, and it states that speech translation works only while online. Koine Live Pro needs a connection throughout, because the translation happens on its servers as you listen.

Is anything kept after the talk?

Very little in the free ones. Google Live Transcribe keeps three days of history, or 24 hours with history off. Apple keeps call captions for one minute or one hour and publishes no session library or export. Microsoft publishes nothing about saved sessions. Koine Live Pro keeps the transcript, your highlights, notes and photos in a private searchable history, and the audio only if you switched recording on.

What does Koine Live Pro cost, and is there a free version?

USD 24.99 a month for four language-hours, plus hour packs that never expire. Transcribing without translating uses a third of an hour per hour, so the month covers about twelve hours of transcript. There is no free tier for the personal plan. Koine Plus on its own, for people who mostly attend other people's sessions, is USD 6.99 a month, and joining someone else's Koine session is free and needs no account.
