How Hosiqo compares and tests toolsFinal recommendation
Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and Zell when automating sales-manager coaching with personalized plans and ai roleplays matters most. Run both through a week of actual calls to see which suits your workflow.

Berlin-based sales performance intelligence platform that analyzes real sales calls, surfaces skill gaps, and delivers AI coaching and roleplays, using GDPR-compliant on-device transcription.
Attendee is an open-source REST API, developed by Attendee Labs, that abstracts the engineering work of building meeting bots into a single developer-friendly interface. Instead of maintaining separate bot stacks for each video platform, developers send one API request and Attendee dispatches a bot that joins a Zoom, Google Meet, or Microsoft Teams call, then returns recordings, transcripts, and real-time media streams. It is built on widely used, battle-tested technologies such as Django, PostgreSQL, and Redis, and is designed to run from a single Docker image so teams can self-host it on their own infrastructure for data residency, compliance, and cost control. The project documents real-time transcription, webhooks, calendar integration, scheduled meetings, and websocket audio input/output. Because it is open source and self-hosted, organizations in regulated industries can keep meeting audio and transcripts inside their own environment rather than routing them through a third-party vendor. The repository is actively maintained with frequent releases, and the project markets itself as a lower-cost alternative to closed-source meeting-bot platforms for developers who want to embed meeting capture and transcription into their own applications. Pricing varies by plan. Check the official website for current pricing.

Zell is a Berlin-based AI platform that captures and analyzes real sales calls to give sales teams performance visibility and automated coaching. It works across video calls, phone calls, and in-person meetings, automatically evaluating call behaviors such as talk patterns, objection handling, and discovery depth, and producing scorecards and instant AI call summaries once conversations end. A skill-gaps dashboard helps managers see who is improving and where coaching is needed, while an AI coaching component (named Dave) generates personalized feedback, coaching plans, and roleplay simulations based on each rep's actual performance, then tracks improvement over time. Zell positions itself as a layer that turns conversation insights into action and automates much of the sales manager's manual coaching workload. As a European company founded in 2024, Zell emphasizes GDPR-compliant, on-device transcription that does not require a meeting bot or store customer data. The company has validated its model with clients across the US, Germany, Italy, and Spain and is backed by European pre-seed investors. It is a newer, privacy-focused alternative to large US conversation intelligence platforms. Pricing varies by plan. Check the official website for current pricing.
