Whether you're on Zoom, Teams, Feishu, or Tencent Meeting, or listening to X Spaces or a YouTube livestream, Cicada gives you live bilingual subtitles and writes structured meeting notes as it listens. When it's your turn to speak, hold the talk key (right ⌥ on Mac, right Ctrl on Windows) and the other side hears your translated voice right in the call. Cicada reads system audio directly without sending bots into the meeting, so no one else notices a thing. On Apple silicon Macs, all speech recognition runs on device, so audio never leaves your computer.

Where it works: Anything that plays sound on your computer. Tencent Meeting, Feishu, DingTalk, WeCom, Zoom, Teams, Google Meet, Webex, Discord, and Telegram voice chats, plus X Spaces, YouTube, Twitch, Bilibili Live, podcasts, and browser-based meetings. On Android, the system blocks recording audio from meeting and call apps—put the call on speaker and use In person instead.

Installers are available on the download page and Releases. All four platforms share the same version number and meeting record format. The sections below use the Mac app to walk through the features.

As the meeting runs, the notes window organizes a summary, topics and key points, conclusions, to-dos, a fishbone diagram, and a glossary of names and terms. Click any conclusion or to-do to jump straight back to the original lines. Pressing ⌘F searches both the canonical spelling and misrecognized variants.

With an AI service connected, misheard names and terms are fixed on the spot: sound-alike typos are corrected right away, while unfamiliar names are asked about once and fixed automatically once you confirm. You can paste your usual spellings into Word list in Settings. After the meeting, select Edit line… to batch-fix the same misheard word across the whole session, with full undo support.

Cicada detects the spoken language within seconds and translates it into your system language; press ⌃⌥S to switch display modes. The subtitle bar only appears when someone speaks and turns see-through under your pointer so it never blocks buttons. On macOS 26 with Apple silicon, Cicada also re-listens on device to refine each line 15 to 30 seconds later, fixing typos and words lost at line breaks.

In a meeting room, click Turn on mic to listen to people around the table. Hybrid meetings use the exact same button: computer audio is marked Online and microphone audio is marked In room, combined in a single record (on macOS 14 and 15, turning on the mic listens only to the table). When speaker audio bleeds into the microphone, Cicada automatically ducks and deduplicates it so nothing is recorded twice; with headphones on, both sides can talk at once and both are kept. Windows and Linux follow the same rules. On the Mac, the small arrow beside the button picks which microphone hears the room (an iPhone or a conference mic, say) without changing the system default.

Hold the right ⌥ key and speak so the other side hears your translated voice in the meeting app. Turning on interpreting automatically switches the system microphone to BlackHole 2ch, a virtual driver you can download and install with one click. With a Ling API key you can use natural voices or clone your own voice from an 8 to 30 second sample; without a key, it uses built-in macOS voices.

Bilingual transcripts, notes, and raw audio recordings are saved on your computer. Click any line to play the recording from that point. The bundled on-device voiceprint model automatically separates different speakers (and fills in their names when a Ling key is set), and you can rename or merge them anytime if it gets someone wrong. After a meeting, you can generate notes retroactively or export to Markdown, Word, or SRT subtitles. Share… turns the notes (and, if you like, the bilingual transcript) into a link with an expiry and an optional password, copied together with one click; before anything is uploaded it is checked for keys, unpublished company information and other sensitive content, and held back if any is found. You can also turn local audio or video files into bilingual records via File › Import Recording or Video…. Right now "you" in the record only covers what you say while holding the talk key; capturing what you say directly in the meeting is on the roadmap.

Apple silicon Macs: Audio capture, language detection, speech recognition, and meeting recordings all stay on your computer. The only data that leaves your Mac is the recognized text (sent for translation and meeting notes) and the short voice clips you speak while holding the talk key with a Ling key configured (if a speech model downloads slowly and you click Use Ling for Now, or if you switch speech recognition to a self-hosted service in Settings › AI Service, meeting audio is also sent to that service). Without an API key, live subtitles, translation, meeting records, and interpreting all work for free. Live notes, one-step voice translation, and voice cloning require your own Ling (Ant Group's LLM service) API key; an hour of meetings costs roughly ¥0.15 to ¥1 RMB, and Ling provides ¥10 of free credit every month, enough for 10 to 50 hours.

Intel Macs, Windows, Linux, Android: Speech recognition runs in the cloud. Spoken audio is sent in segments to Ling's Ming or your chosen service (OpenRouter, ZenMux, etc.), so an AI service key is required. Recordings and meeting records still stay only on your device.

The Mac app only asks for a permission when you use the corresponding feature, and everything else works normally if you decline:

• Transparent networking: Cicada only connects to the internet for translation (translate.googleapis.com), your configured AI service (such as api.ant-ling.com), downloading the Apple-notarized BlackHole driver (verified against SHA-256), and checking GitHub once a day for updates. There is no analytics, no tracking, and no server of our own.
• Local storage: Records and recordings live in ~/Library/Application Support/LiveSubs. Your key and voice sample are readable only by your current system account and excluded from Time Machine and logs.
• Hidden from screen capture: On Mac, screen sharing, screen recordings, and screenshots cannot capture the notes window; you can manually turn on Show in screen sharing when recording a demo.

The table below shows the setup on Apple silicon Macs. When using a self-hosted service (Other (OpenAI-compatible)), you can turn on Send audio and text only to your service in Settings › AI Service to bypass Google completely.

1. Sign up and log in on the Ling open platform, create a token, and copy the key starting with sk-.
2. Open Settings › AI Service in Cicada (or the banner at the top of the notes window), paste the key, and save.

Can't sign up for Ling? At the top right of Settings › AI Service (or by clicking Can't use Ling? during onboarding), you can switch to OpenRouter, ZenMux, OpenAI, or any OpenAI-compatible service (including local or LAN services like Ollama, vLLM, SGLang, Qwen3-ASR, and Whisper). Live notes and full-sentence translation work with all of them, and OpenRouter and ZenMux can also use natural Gemini voices for interpreting; one-step voice translation and voice cloning are supported only by Ling. When Windows, Linux, or Android switches to another service, listening to the other side also goes through that service, so subtitles run 1–2 seconds behind Ling. If a connection fails, Settings tells you directly whether it's a key, model, or proxy issue (see the setup page for proxy details).

Installers are on the Releases page and the website, and you can verify SHA-256 checksums against checksums.txt in Releases. If you run into questions, reach out to the author @wquguru on X.

Requires macOS 14.4+ (Apple silicon and Intel). On Apple silicon with macOS 14.4–15, first go to System Settings › Keyboard to turn on Dictation and add the languages you want heard; macOS 26 uses the new on-device model directly without needing Dictation; Intel Macs use cloud-based Ming recognition and require a Ling key.

Download Cicada-<version>-macOS-AppleSilicon.dmg or Cicada-<version>-macOS-Intel.dmg and drag Cicada into Applications (verify with shasum -a 256 Cicada-*.dmg). The app is not notarized by Apple yet, so if the first launch is blocked, go to System Settings › Privacy & Security and click Open Anyway. Follow the onboarding guide to grant permissions and try the sample meeting.

Requires Windows 10 2004+ (x64 or Snapdragon ARM64). Download the installer and double-click to install without admin rights. If SmartScreen blocks it, click More info › Run anyway. When you use interpreting, the guide walks you through installing the free VB-Cable virtual microphone.

Requires Ubuntu 22.04 or 24.04 desktop (x86_64 or arm64). Download Cicada-<version>-Linux.tar.gz and run tar xzf Cicada-<version>-Linux.tar.gz && cicada-linux/install.sh in a terminal. Interpreting automatically creates a "Cicada Microphone" with no driver to install. Linux windows cannot hide from screen sharing, so the notes window indicates that it is visible when sharing your screen. To enable Settings › General › Save meeting audio, first install system third-party media formats (such as ubuntu-restricted-extras) to provide an AAC encoder. Turning on Settings › Word list › Fix misheard words live sends one extra text request per sentence.

Requires Android 10+. Download and install Cicada-<version>-Android.apk; on Android 15 and later, allow restricted settings in App info the first time you turn on floating subtitles. It also includes on-device voiceprints to separate speakers and fixes misheard words live while listening. Call and meeting apps block internal audio capture on Android—just put the call on speaker and switch to In person.

In rough order of priority; feel free to open an Issue for what you'd like to see. See docs/ROADMAP.md for details.

• Record my own speech: Continuously listen to the microphone with echo cancellation during meetings so what you say directly is also included in records and notes.
• Code signing and notarization: Official signing and notarization for Mac and Windows installers to eliminate security prompts and move AI keys back to the system keychain.
• Speaker recognition: Remember frequent coworkers' voices on device and recognize them automatically in future meetings.
• Notes without a key: Generate meeting notes on supported Macs using Apple's on-device models.
• Android on app stores: No more manual APK installs.
• iPhone and iPad: Starting with listening to meeting rooms, face-to-face interpreting, and meeting records.

Quit Cicada and drag it from the Applications folder to the Trash. Meeting records and recordings are in ~/Library/Application Support/LiveSubs and can be deleted manually if no longer needed. To clear settings, run:

defaults delete com.wquguru.cicada

The Mac app only requires Xcode Command Line Tools (xcode-select --install) and has no third-party dependencies. On macOS 27, if SwiftUIMacros is reported missing, install full Xcode and run sudo xcode-select -s /Applications/Xcode.app. For building on other platforms, see windows/README.md, linux/README.md, and android/README.md.

scripts/build.sh            # dev build → build/Cicada.app ("Cicada Dev", runs alongside the release app)
