How Hosiqo compares and tests toolsFinal recommendation
Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and ProspectBoss when using ai call scores and summaries to coach reps and plan next steps matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Cloud power dialer for outbound sales with AI that scores, summarizes, and suggests next steps on every conversation.
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.

ProspectBoss is a cloud-based outbound power dialer built to help sales teams call faster, protect their phone numbers, automate follow-up, and convert more conversations into appointments. Its power dialer, marketed as "Call Hammer" technology, automates rapid sequential dialing to maximize the number of prospects a rep reaches per hour, and includes automated voicemail dropping so reps can leave pre-recorded messages without waiting. The platform layers AI on top of calling, describing an assistant that listens to conversations and then scores, summarizes, and suggests next steps for each call, while automating SMS and email follow-up and tracking outcomes. ProspectBoss emphasizes deliverability and compliance with STIR/SHAKEN support, spam-likely prevention, and phone-number registration with major carriers to keep outbound numbers in good standing. It integrates with CRMs including Salesforce, HubSpot, and Zoho, and offers real-time conversation data and analytics. The product is primarily targeted at real estate agents, insurance producers, and home-services companies, and is a live, actively offered product with current pricing and trial options. Pricing varies by plan. Check the official website for current pricing.
