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 SmartDepo when extracting key admissions from testimony for case preparation matters most. Try them side by side on real calls before deciding — needs vary by team.

AI deposition summary platform for litigators that produces cited summaries with page-line citations.
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.

SmartDepo is an AI-powered deposition summary platform built for litigation attorneys that analyzes deposition transcripts and generates comprehensive summaries with precise citations. It offers several summary products, including page/line summaries, key admissions analysis, deposition abstracts, and deposition memos, allowing legal teams to choose the format that fits a given task. SmartDepo emphasizes accurate page-line citations that can be carried directly into court filings, and it uses topic detection to organize information in a way that mirrors how attorneys structure case materials. The platform is designed to analyze entire transcripts without omissions and pairs its AI output with human review by legal professionals, and it reports producing summaries within minutes. SmartDepo is part of Rev, a speech-to-text company, which provides established backing for its operations. Because it is focused specifically on deposition summarization rather than general meeting notes, it is most useful to litigators, paralegals, and litigation support staff who need to quickly extract admissions, build chronologies of testimony, and prepare filings from lengthy deposition records. Its citation-first approach is tailored to the accuracy and traceability demands of legal work. Pricing varies by plan. Check the official website for current pricing.
