How Hosiqo compares and tests toolsFinal recommendation
Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and MeetingBot when teams that want to self-host meeting capture on their own aws infrastructure for privacy matters most. Run both through a week of actual calls to see which suits your workflow.

Open-source meeting bot API that sends bots into Google Meet, Microsoft Teams, and Zoom to record calls, deployable to your own AWS infrastructure.
Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.

MeetingBot is an open-source meeting bot API that provides the infrastructure for sending bots into Google Meet, Microsoft Teams, and Zoom calls and recording them, so developers can build applications on top of meeting-recording data with a small amount of code. The project exposes a unified REST API for managing bots and accessing meeting data including video, audio, transcripts, and metadata, and ships with a visual dashboard for managing bots and viewing captured data. A distinguishing characteristic is that its entire infrastructure is defined using Terraform and deployed to AWS, which is intended to let teams self-host the platform on their own cloud account to keep meeting data private and control costs. The stack is primarily TypeScript, using a Next.js frontend, an Express backend, PostgreSQL, tRPC, and Drizzle ORM, and the project runs on scalable AWS ECS infrastructure. MeetingBot is positioned as an open-source alternative to closed-source meeting-bot vendors for developers who want recording and transcription capabilities without sending data through a third party. The project maintains a public landing page, an active community channel, and a GitHub repository under the LGPL-3.0 license. Pricing varies by plan. Check the official website for current pricing.
