How Hosiqo compares and tests toolsFinal recommendation
Shortlist CloudTalk when reviewing and coaching sales calls using ai summaries, sentiment, and talk ratios matters most, and OpenTranscribe when collaborative review of transcripts with time-stamped annotations matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

CloudTalk is a cloud-based business calling and call-center platform that pairs voice infrastructure with an AI Conversation Intelligence layer for sales, support, and operations teams. On top of its phone system (international numbers, IVR, call routing, recording, dialers, SMS, and WhatsApp), CloudTalk automatically converts recorded calls into multilingual transcripts and stores them in a searchable interaction database. Its AI then generates instant call summaries and smart notes, applies automatic tags, extracts the key topics discussed, and scores calls against custom criteria. Sentiment analysis interprets the mood of each speaker segment by segment, classifying calls as positive, neutral, or negative, while talk/listen ratio tracking surfaces coaching opportunities across agents. Summaries and notes can sync into CRMs such as Salesforce, HubSpot, and Pipedrive through CloudTalk's broad integration catalog. Conversation Intelligence is available as a paid add-on across CloudTalk's calling plans. It is aimed at teams that handle high call volumes and want to review, analyze, and coach on conversations at scale rather than manually.

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.
