How Hosiqo compares and tests toolsFinal recommendation
Shortlist Allo when sales teams that want every outbound and inbound call recorded, transcribed, and logged to the crm automatically 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.
Mobile-first AI business phone system that records and transcribes sales calls, writes follow-ups, and syncs everything to your CRM automatically.
Self-hosted, containerized web app for transcribing and analyzing audio/video with WhisperX, speaker diarization, search, and collaboration.
Allo is an AI-powered business phone system aimed at sales teams, support, and operations that records every call, transcribes it in real time, and syncs the recording, transcript, and an AI-generated summary to a CRM automatically. Positioned as mobile-native and quick to set up, it focuses on letting reps spend time selling rather than logging calls. Each conversation is recorded with consent-message compliance options, transcribed with speaker identification, and condensed into a shareable AI recap. Allo can then draft personalized follow-up emails and SMS based on what was discussed. The platform includes an AI receptionist for answering inbound calls, voicemail transcription, multi-tag organization of calls, and team collaboration features such as cascade ring and warm transfers. Managers can pull call recordings and AI transcripts to find coaching opportunities, while reporting dashboards surface connection rates, conversion tracking, funnels, and heatmaps. Allo integrates with CRMs including HubSpot, Salesforce, Pipedrive, Attio, and Apollo, and exposes an MCP endpoint to connect the phone system to AI assistants. It is a live, operating product as of 2025/2026. Pricing varies by plan. Check the official website for current pricing.

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.
