6. Download & install

Visit crossmeet.com/download
Click "Download for Windows x64", get CrossMeet-Setup-X.X.X.exe (~80 MB)

⚠️ Antivirus may false-positive. CrossMeet is signed with a code signing certificate; please add to your AV trust list. We're applying for an EV certificate.

7. First activation

Launch CrossMeet
First launch downloads ~100 MB of core Python deps (1-2 minutes, see progress bar)
After main UI loads, click Settings → Licensing on the left
Paste your license_key, click "Activate"
Wait 3-5s for network verification
See "License active · 2 devices used 1/2" — success!

8. Configure engines

Settings → AI Engines:

ASR (speech recognition): default is Whisper API (cloud). With NVIDIA GPU you can install local Whisper for full offline operation
TTS (speech synthesis): default Edge TTS (free, fluent). For more natural voice try OpenAI TTS or Aliyun TTS
LLM Translation: default OpenAI GPT-4o-mini. You can switch to Claude, local Ollama, etc.

API keys go into the corresponding engine card. Cloud engines work out-of-the-box; local engines need a one-click install (downloads model, takes a few minutes).

9. First translation session

Back to main UI, click Meeting Mode top-left
Pick audio source:
- Single (mic): translate only what you say
- Single (system): translate only what your speakers play (good for English videos)
- Dual: left panel = the other side (system audio), right panel = you (mic). Used for cross-language calls
Pick a language pair (e.g. EN → ZH or ZH → EN)
Click Start
Start speaking or play audio — source + translation stream out in real time

10. Advanced features

After getting comfortable with basics:

Interpret mode: bidirectional simul-interpret + compose-bar input — essential for business meetings
Virtual mic output (vMic): TTS goes directly to the other side
Glossary: lock proper noun translations
RAG: upload company materials to inject LLM context
Quick phrases: one-click common expressions

See the dedicated docs for each feature.

11. Trouble?

Crash / bug: automatic crash reports go to us; you can also manually report via Settings → Help → Report Issue
Activation fails: check key spelling, network; restart and retry
No audio: check Settings → Audio → correct input/output device picked
Bad translation quality: try a different LLM (Claude > GPT-4o > Ollama) or add a glossary
