How Hosiqo compares and tests toolsFinal recommendation
Shortlist Cresta when assisting contact-center agents in real time during customer conversations 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.

Cresta is an enterprise customer-experience AI platform that unifies human and AI agents across voice and digital channels. It captures conversations through integrations with major contact-center systems such as Genesys, NICE, Salesforce, Twilio, and Amazon Connect, then analyzes those interactions at scale to surface behavioral insights and deliver real-time guidance. Its Agent Assist listens to live conversations and provides agents with in-the-moment suggestions, knowledge, and next-best actions, while a Knowledge Agent proactively surfaces context-aware answers without manual prompting. Cresta's conversation intelligence analyzes 100% of interactions to identify the behaviors that drive outcomes, and its automated quality management scores conversations across the board so supervisors gain visibility without manual sampling. The platform also offers autonomous AI agents that can resolve customer conversations end to end, plus an Agent Operations Center that gives supervisors real-time visibility and intervention tools across both human and AI-led conversations. Cresta is built for large enterprise contact centers in industries such as financial services, travel and hospitality, telecommunications, insurance, and healthcare that need real-time assistance, coaching, and analytics at scale. 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.
