1. What Is wquguru/cicada (And How Does Bot-Free Live Interpreting Work)?

wquguru/cicada (cicada.indaloop.app) is an open-source (Apache-2.0) native macOS application written in Swift 5 that surged by +636 GitHub stars in a single day (1,124+ total stars).

Traditional meeting transcription tools (like Otter.ai, Fireflies, or Fathom) force you to invite an intrusive "Recording Bot" into a Zoom or Teams room—and they don't work at all when you are listening to an X Space, Discord Stage, or YouTube Livestream.

Cicada solves this by tapping directly into macOS system audio and Apple's on-device SpeechAnalyzer framework:

1. Click-Through Live Bilingual Subtitles (⌃⌥S):
   Within seconds of anyone speaking in Zoom, Teams, Feishu, Tencent Meeting, X Spaces, or YouTube Live, Cicada detects the spoken language locally and renders a floating bilingual subtitle bar. Pressing ⌃⌥S cycles between the full Notes window, the compact Subtitle Bar, and Hidden mode. When your mouse cursor hovers over the subtitle bar, it automatically turns transparent and click-through so it never blocks buttons underneath.
2. Hold-Right-⌥ Simultaneous Interpretation (BlackHole 2ch Virtual Mic):
   Need to speak back in a foreign-language call? Hold down the Right ⌥ (Option) key and speak in your native language. Cicada automatically routes its translated speech output through a one-click installed BlackHole 2ch virtual microphone so everyone in the meeting hears your translated voice in real time (using either macOS system voices for free, or 8–30 second cloned voices via a Ling/Ming API key).
3. Structured Live Notes, Fishbone Diagrams & Variant-Aware Glossary:
   While the stream or call runs, Cicada builds a structured summary, topic breakdown, conclusions, action items (to-dos), an interactive fishbone diagram, and a unified glossary of people and technical terms. Clicking any conclusion or to-do jumps straight to the exact timestamped lines in the bilingual transcript, and pressing ⌘F searches both canonical terms and misheard phonetic variants.
4. One-Click .srt, Markdown & Word Export:
   All recordings, speaker-separated bilingual transcripts, and notes stay on your Mac and can be exported at any time to .srt subtitles, Markdown (.md), or Word (.docx).

3. System Requirements & Critical Setup Gotchas (macOS 26+ & BlackHole 2ch)

Before downloading Cicada.dmg or building from source with Xcode, check these four critical requirements:

1. Requires macOS 26+ (Tahoe) on Apple Silicon (M1 / M2 / M3 / M4 / M5):
   Because wquguru/cicada relies on Apple's latest on-device SpeechAnalyzer and SpeechTranscriber APIs for zero-cost local speech recognition, it only runs on Apple Silicon Macs running macOS 26+. Intel Macs, Windows PCs, and Macs still on macOS 14 (Sonoma) or macOS 15 (Sequoia) cannot run the native app.
   • Workaround for Windows, Linux, or macOS 14/15 users: If you need voice cloning, multilingual audio translation, or .srt dubbing on macOS 14/15 or Windows, use ElevenLabs Dubbing Studio directly in your browser (or local open-source TTS models like Audio8-TTS-Realistic).
2. Four Granular macOS Permissions (Requested Only When Needed):
   • System Audio Recording: Required to listen to Mac playback for subtitles and notes (never records your screen or Cicada's own output).
   • Microphone: Requested only when you enable Simultaneous Interpreting and hold the talk key.
   • Input Monitoring: Used only to detect whether the Right ⌥ (Option) key is held down by itself. (Tip: If you don't want to grant Input Monitoring permission, change the talk shortcut in Settings to a ⌃ or ⌘ key combination!)
   • Administrator Password (One-Time): Needed once to install the BlackHole 2ch virtual audio driver and restart coreaudiod so other call participants can hear your translated voice.
3. Quarantine Attribute on Self-Built / Unsigned Releases:
   If macOS Gatekeeper blocks first launch, strip the quarantine flag in Terminal:

   xattr -cr /Applications/Cicada.app

4. The 3-in-1 Creator Playbook: Turn Livestreams & X Spaces into Global Content Waves

Podcasters, tech commentators, and media creators spend hours listening to 2-hour English livestreams (like Apple/OpenAI keynotes, Bloomberg streams, or X Spaces) to produce localized summaries and short-form clips. Here is how to combine wquguru/cicada + ElevenLabs + HeyGen + WaveWeaver into a 15-minute pipeline:

Step 1: Capture Live Bilingual Notes & .srt Subtitles (wquguru/cicada)

1. Open the YouTube Live keynote, X Space, or Zoom interview on your Mac and press ⌃⌥S in Cicada to start live bilingual transcription and fishbone note generation.
2. When the stream ends, click any high-signal conclusion in the Notes window to jump to the exact original quote, and export both the Markdown summary (.md) and the time-synced .srt subtitle file.

Step 2: Dub & Voice-Clone Highlights in 29+ Languages (ElevenLabs Voice AI)

While Cicada's built-in voice output is designed for quick live call responses, publishing high-retention YouTube, TikTok, or Podcast episodes requires studio-grade vocal emotion:

1. Upload the highlight clip and your Cicada .srt file into ElevenLabs Voice AI.
2. Use ElevenLabs Professional Voice Cloning and Dubbing Studio to generate broadcast-quality localized audio tracks (preserving each speaker's timbre, pacing, and emphasis across English, Spanish, Japanese, Mandarin, German, and 24+ other languages).

Step 3: Render Video Recaps & Distribute via WaveWeaver's 6-Step Content Loop

1. Optional On-Camera Commentary (HeyGen): Feed the top 3 takeaways from Cicada's fishbone diagram into HeyGen AI Avatar Studio to generate a 60-second talking-head breaking-news commentary clip without setting up lighting or cameras.
2. Scale Across Every Channel (WaveWeaver): Import your Cicada Markdown notes and dubbed clips into WaveWeaver:
   • Channel Workbench: Manage your daily livestream recap and podcast localization queue.
   • Intelligence Base: Archive Cicada's structured transcripts, glossaries, and fishbone diagrams as searchable domain knowledge.
   • Campaign & Topics: Pick the most controversial or insightful quotes from the stream to anchor your campaign.
   • Multi-Format Studio: Automatically convert one livestream transcript into a YouTube Short script, a 7-Slide Visual Summary Carousel (paired with architecture diagrams from stack-diagram), and an X Thread + Newsletter issue.
   • Scheduled Distribution & Post-Publish Review: Schedule synchronized posts across time zones and review engagement metrics to refine your next stream breakdown.
3. Own Your Audience via Creator Email Sequences (Kit): Export your structured Cicada Markdown notes directly into Kit (formerly ConvertKit) to send bilingual livestream digests, distribute audio show notes, and monetize your audience through paid newsletter tiers and digital downloads.

Frequently Asked Questions (FAQ)

What is wquguru/cicada?

wquguru/cicada (Cicada) is an open-source (Apache-2.0 license) native Swift 5 macOS app that provides bot-free live bilingual subtitles, simultaneous voice interpretation (via BlackHole 2ch), and structured AI meeting notes (including fishbone diagrams, action items, and .srt / Markdown exports) for any audio playing on your Mac—including Zoom, Teams, Feishu, X Spaces, and YouTube livestreams.

Why does wquguru/cicada require macOS 26+ and Apple Silicon?

Cicada performs on-device language detection and speech transcription using Apple's native SpeechAnalyzer and SpeechTranscriber APIs introduced in macOS 26 (Tahoe) for Apple Silicon (M1–M5). Because audio recognition runs locally on the Apple Neural Engine without sending raw meeting audio to a cloud bot, older macOS versions (macOS 14/15), Intel Macs, and Windows PCs are not supported by the native app.

How does simultaneous interpretation work in Cicada?

When you enable Simultaneous Interpreting in Cicada, the app installs and switches your system microphone input to the BlackHole 2ch virtual audio driver. Whenever you hold down the Right ⌥ (Option) key and speak, Cicada translates your speech and broadcasts the translated voice directly into your Zoom, Teams, or Feishu call using either built-in macOS voices (free) or an 8–30 second cloned voice.

How can I dub Cicada transcripts or clone voices on Windows or older macOS versions?

If you are on Windows, Linux, or macOS 14/15—or want studio-grade multilingual dubbing for YouTube, podcasts, and social video—export your .srt subtitles or audio clip and upload them to ElevenLabs Voice AI, which runs in any browser and supports 29+ languages with emotional voice cloning and multi-speaker dubbing.
