How Hosiqo compares and tests toolsFinal recommendation
Shortlist AudioPen when capturing and refining personal ideas, journal entries, or brainstorms by voice matters most, and Slipbox when privacy-conscious professionals who cannot use cloud meeting bots matters most. Try them side by side on real calls before deciding — needs vary by team.

Privacy-first, bot-free AI meeting companion that captures system audio locally on Mac and Windows and turns it into transcripts, notes, and summaries.
AudioPen is a voice-to-text tool that captures spoken thoughts and turns them into polished written notes. You record your voice (or upload an audio file), and AudioPen transcribes the speech, then rewrites it into clear, structured text by fixing grammar, cutting filler words, and organizing rambling input into coherent prose. Rather than producing a verbatim transcript, it reshapes what you said into finished writing in a style you select or train over time, with preset and custom styles available. It supports multiple languages and can transcribe speech in one language while writing the output in another. A SuperSummaries feature combines several notes into a single cohesive summary, and existing notes can be reformatted for different purposes such as emails or to-do lists. Built by independent developer Louis Pereira, it runs across iOS, iPad, Apple Watch, Android, Mac, and a Chrome extension, with Zapier and webhook integrations for sending notes elsewhere. It is aimed at people who think out loud and want to convert informal speech into professional written content.

Slipbox is a privacy-first AI meeting companion built for individual professionals and teams who want to capture meetings without sending a bot into the call. Instead of joining a conference as a visible participant, Slipbox runs on your own machine and captures the device's system audio alongside your microphone, then transcribes the conversation on-device in real time. As the meeting progresses it can surface real-time insights and cues, and once the conversation ends it generates AI summaries using customizable templates, tagged notes, and searchable meeting records. Because the core transcription happens locally, audio does not need to leave the device, and the product uses a hybrid model in which optional cloud features can be turned on when needed; users can also bring their own LLM API key or point Slipbox at local models such as Ollama to keep data within their firewall. It works across common communication apps including Zoom, Microsoft Teams, Google Meet, Slack, FaceTime, WhatsApp, Signal, Telegram, Discord, and Webex, and integrates with note tools like Obsidian. Slipbox is available for macOS, Windows, and iPhone, and is suited to consultants, researchers, and privacy-conscious knowledge workers who want a personal meeting record without a meeting bot. Pricing varies by plan. Check the official website for current pricing.
