How Hosiqo compares and tests toolsFinal recommendation
Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and Koncert when managers coaching reps from recorded calls and a remote salesfloor matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

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.

Koncert is a B2B sales engagement platform built around AI-powered dialing, call recording, and coaching for outbound teams. Its dialer suite includes options such as an AI Parallel Dialer and an AI Flow Dialer that filter voicemails and connect reps to live answers to increase connected conversations and connect rates. Calls are recorded and run through conversation intelligence that scans for objections and other signals so managers can coach reps at scale, and a remote Salesfloor gives managers a virtual workspace for real-time coaching during calls. Koncert also includes a multi-channel cadence sequencer spanning phone, email, video, text, and social, plus caller ID management that selects local numbers and monitors number health. For practice and training, Koncert offers AI PitchLab, an add-on where reps rehearse pitches against AI-powered buyer personas without the pressure of a live prospect, with objection-handling practice and automatic transcription and scoring of performance. Together these capabilities target outbound sales teams, SDRs, and managers who want dialing, real-call analysis, and structured roleplay practice within one platform. Pricing varies by plan. Check the official website for current pricing.
