How Hosiqo compares and tests toolsFinal recommendation
Shortlist Circleback when automatically capturing notes and action items so attendees can stay focused in meetings matters most, and OpenTranscribe when collaborative review of transcripts with time-stamped annotations matters most. Run both through a week of actual calls to see which suits your workflow.

Circleback is a Y Combinator-backed AI meeting assistant that captures, transcribes, and organizes conversations automatically. It works with Zoom, Google Meet, Microsoft Teams, Webex, GoTo, Slack huddles, and in-person meetings, and offers a botless option via its desktop app for those who prefer not to send a bot into calls. After each meeting it produces structured notes, identifies and auto-assigns action items, and provides searchable transcripts with speaker identification across 100+ languages. AI-driven automations and "Insights" can push data into connected tools and answer questions across past meetings. Integrations include Gmail, Outlook, Slack, Google Calendar, HubSpot, Salesforce, Attio, Zoho, Linear, Notion, Monday, Zapier, and Make, plus developer access through MCP, a CLI, and webhooks. Circleback states SOC 2, GDPR, EU-US DPF, and HIPAA compliance, and offers mobile and desktop apps. New users can try it free before subscribing.

OpenTranscribe is a self-hosted, containerized web application for transcribing and analyzing audio and video files using current AI models. It is built with a FastAPI backend, a Svelte/TypeScript progressive web app frontend, and a Docker-based stack that includes PostgreSQL, Redis/Celery task queues, MinIO object storage, and OpenSearch for full-text indexing. Transcription is handled by WhisperX with the large-v3-turbo model and Faster-Whisper, supporting more than 100 languages, while automatic speaker diarization uses PyAnnote v4 with overlap detection. The project is licensed under AGPL-3.0 and is actively maintained, with v0.4.1 released in April 2026. Beyond transcription, OpenTranscribe provides AI-powered summarization (including BLUF-format and custom JSON schemas), topic extraction, and content analysis through multiple LLM providers such as OpenAI, Claude, vLLM, Ollama, and OpenRouter. Collaboration features include time-stamped comments and annotations, and the platform can automatically import media from local folders, S3, and SMB shares. It also supports a set of cloud ASR providers as alternatives to local transcription, giving teams flexibility between fully local processing and managed services while keeping the application running on their own infrastructure. Pricing varies by plan. Check the official website for current pricing.
