How Hosiqo compares and tests toolsFinal recommendation
Shortlist Backtrack when exhibitors capturing booth and 1:1 buyer conversations at trade shows matters most, and WhisperLiveKit when building privacy-first transcription into custom applications via compatible apis matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Backtrack is an AI meeting intelligence product focused on a niche that most notetakers ignore: in-person B2B conversations at trade shows, conferences, and hosted buyer events. Rather than running as a meeting bot, Backtrack captures live 1:1 conversations and converts them into transcripts, structured summaries, and CRM-ready follow-up notes so sales teams do not have to take notes during busy events. Its consumer app, marketed as Backtrack, also offers retroactive recording that continuously buffers recent audio and saves only the last several minutes when the user explicitly chooses to, which is useful for capturing a conversation that has already started; the company stores audio locally on-device until the user decides to upload or share, and recordings are not live-streamed. For events, Backtrack offers pre-configured capture that activates around scheduled meetings, transcription tuned for noisy venues, summaries covering buyer intent, objections, priorities, and next steps, and anonymized trend reports for organizers. It supports transcription in over 100 languages and provides an opt-out path for attendees, emphasizing transparency around recording. Backtrack is aimed at exhibitors, event organizers, and sales teams who need reliable conversation capture and follow-up in event settings. Pricing varies by plan.

WhisperLiveKit is an open-source, self-hosted toolkit for ultra-low-latency real-time speech-to-text and speaker diarization. Rather than naively running Whisper on each audio chunk, it uses state-of-the-art simultaneous-speech research for intelligent buffering and incremental processing, which preserves transcription quality while streaming results with minimal latency. The project ships a complete backend built on FastAPI with WebSocket support, an OpenAI-compatible REST API, a Deepgram-compatible WebSocket protocol, and a simple, customizable HTML and JavaScript web interface that captures microphone audio and streams it to the server. It supports multiple ASR backends including Whisper variants, Voxtral, and Qwen3-ASR, covers 200+ languages with translation, and includes real-time speaker diarization and voice activity detection to reduce processing overhead. It can handle multiple concurrent users on a single backend and is distributed via PyPI with Docker images for both GPU and CPU. Licensed under Apache 2.0 and actively maintained into 2026, the project explicitly lists meeting transcription, accessibility tooling, and podcast or call transcription with speaker identification among its intended use cases, making it a practical building block for private, on-premise meeting transcription pipelines. Pricing varies by plan. Check the official website for current pricing.
