How Haide AI Call Assistant Works

Haide captures call audio through VB-Cable, sends the routed audio directly to AssemblyAI for live transcription, detects pauses, and uses OpenAI to suggest document-grounded answers from your embedded .txt files. Optional Cerebras can provide speed-first suggestions without searching your documents.

The audio pipeline: from live speech to AI suggestions

Haide AI Call Assistant routes call audio on your Windows PC, transcribes it with AssemblyAI, and detects pauses to trigger suggestions. Local document search supplies context for OpenAI, while optional Cerebras suggestions provide a separate speed-first path during interviews, sales calls, and meetings.

1 · Audio source

Your calling application

Haide works alongside Zoom, Microsoft Teams, MicroSIP, Webex, and browser-based calls. The calling app supplies the other participant's audio. Your microphone normally stays on its usual input device, so you can keep speaking as normal.

2 · On your Windows PC

VB-CABLE audio routing

Set the calling app output to VB-CABLE Input so Haide can capture the routed audio. Enable Listen to this device for VB-CABLE Output and choose your headphones or speakers to keep hearing the caller. Browser calls can use Windows per-app audio output settings.

3 · Speech to text

AssemblyAI live transcription

Click START to send routed call audio directly to AssemblyAI using your API key. AssemblyAI converts speech into text during the conversation, and Haide displays the live transcript. This cloud transcription stage requires an internet connection.

4 · Trigger suggestions

Local pause detection

Haide detects pauses on your computer and uses the transcribed question to request AI suggestions. You do not need a hotkey for each question. The document-grounded path and optional Cerebras path then use the question text in different ways.

Document-grounded path

Local search and OpenAI

Haide uses semantic search to find relevant excerpts in your locally embedded .txt files, rather than relying only on exact keywords. Retrieved Knowledge shows the matches. Haide sends question text and relevant document context directly to OpenAI for a concise suggestion grounded in your notes.

Speed-first path

Optional Cerebras suggestions

If you configure a Cerebras API key, Haide can also send the question text directly to Cerebras for a speed-first suggestion. This separate path does not search your documents or use retrieved excerpts. OpenAI remains the document-grounded path.

What stays local, and what goes to AI providers?

Your knowledge files, document embeddings, semantic search, and pause detection stay on your computer. Call audio goes directly to AssemblyAI; question text and relevant document excerpts go directly to OpenAI; optional Cerebras requests use question text. Haide servers do not relay or process this call content. Local-first means fewer processing layers, not that cloud AI features work offline.

Check the pipeline before an important call

Use a short test call to confirm caller playback, live transcription, and relevant results from your notes. Click Embed after changing your .txt files, and click STOP when the call ends to avoid continued provider usage. Follow the illustrated Windows and VB-CABLE setup guide for the checklist, or visit Haide support for troubleshooting.

Capabilities

What makes it different

The product behavior matches the home page promise: fast, local, and grounded in your own materials.

Detail

OpenAI document-grounded path

After a pause, Haide searches your embedded .txt documents and sends relevant context directly to OpenAI for a concise suggested answer.

Detail

Silence detection

Haide waits for a natural pause before firing, so you do not need a hotkey or manual trigger.

Detail

Document-grounded answers

Haide searches your embedded notes, resume, product docs, and prep material before generating its answer.

Detail

Optional Cerebras speed-first answers

If configured, Cerebras can provide a fast suggestion from the live question text. It does not search your documents.

Detail

Fast because it runs locally

Haide keeps audio routing, pause detection, recent conversation state, document search, and embeddings on your PC, so the app can react quickly without waiting on a Haide-hosted SaaS layer.

Detail

Local-first privacy

Unlike SaaS alternatives, Haide does not route call content through Haide middle servers. It connects directly to the providers you configure with your own API keys.

Detail

Session memory

Haide keeps the recent conversation in mind, which improves follow-up answers and reduces repetition.

Detail

Works with desktop call apps

Because audio is captured through VB-Cable, Haide works with most desktop communication tools that play system audio.
