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 Spellar AI when consultants generating templated summaries and action items per meeting matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

A bot-free AI meeting note taker for Mac, iOS, and web that records on-device and produces transcripts, summaries, and action items.
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.

Spellar AI is a bot-free meeting note taker built by Spellar LTD for professionals who want their conversations captured without a bot joining the call. The app records directly on the user's Mac, iPhone, or iPad, so no participant appears in the meeting, and it produces transcripts in many languages with intelligent language detection. At the end of each meeting Spellar generates a structured summary that highlights key points and action items, and it offers customizable summary templates so the output can match different meeting types. A distinguishing feature is its model flexibility: users can switch between AI models such as different GPT, Gemini, Claude, and Perplexity options per meeting, per template, or per question, and a real-time copilot can assist during the conversation. Privacy is configurable: server-side transcription is opt-in rather than default, and users can run transcription on-device or bring their own AI key to keep calls private. Spellar syncs across macOS, iOS, and the web, and supports one-click export to tools like Notion, Jira, Linear, and Google Docs. It suits sales reps, consultants, and professionals who want discreet capture plus flexible, exportable meeting notes. Pricing varies by plan. Check the official website for current pricing.
