How Hosiqo compares and tests toolsFinal recommendation
Shortlist Némos when recording and transcribing in-person meetings or lectures on an iphone or apple watch matters most, and OpenTranscribe when collaborative review of transcripts with time-stamped annotations matters most. Run both through a week of actual calls to see which suits your workflow.
An Apple-focused "second brain" app that records and auto-transcribes voice memos and meeting notes entirely on-device using Apple Intelligence.
Self-hosted, containerized web app for transcribing and analyzing audio/video with WhisperX, speaker diarization, search, and collaboration.
Némos is a personal knowledge management ("second brain") app for the Apple ecosystem that captures and automatically organizes many content types, including voice memos that it records and transcribes on-device. Rather than joining video calls as a bot, it captures audio directly from the iPhone or Apple Watch and converts speech to text locally using Apple Intelligence Foundation Models, so data stays on the device. Transcribed audio becomes fully searchable, and recordings can be turned into formats such as bullet points, summaries, meeting notes, emails, or journal entries. Beyond voice, Némos handles screenshots with OCR, links, PDFs, notes, photos, and more, naming and filing them automatically without manual tagging. It runs on iPhone and iPad (with Apple Watch recording, Siri commands, and Chrome, Safari, and Firefox extensions), and offers two-way sync with Apple Reminders, Calendar, Notes, Photos, Files, Maps, and iCloud. It is aimed at students, researchers, writers, and professionals who want private, low-effort capture of voice and other notes. As of mid-2026 it is in private beta.

OpenTranscribe is a self-hosted, containerized web application for transcribing and analyzing audio and video files using current AI models. It is built with a FastAPI backend, a Svelte/TypeScript progressive web app frontend, and a Docker-based stack that includes PostgreSQL, Redis/Celery task queues, MinIO object storage, and OpenSearch for full-text indexing. Transcription is handled by WhisperX with the large-v3-turbo model and Faster-Whisper, supporting more than 100 languages, while automatic speaker diarization uses PyAnnote v4 with overlap detection. The project is licensed under AGPL-3.0 and is actively maintained, with v0.4.1 released in April 2026. Beyond transcription, OpenTranscribe provides AI-powered summarization (including BLUF-format and custom JSON schemas), topic extraction, and content analysis through multiple LLM providers such as OpenAI, Claude, vLLM, Ollama, and OpenRouter. Collaboration features include time-stamped comments and annotations, and the platform can automatically import media from local folders, S3, and SMB shares. It also supports a set of cloud ASR providers as alternatives to local transcription, giving teams flexibility between fully local processing and managed services while keeping the application running on their own infrastructure. Pricing varies by plan. Check the official website for current pricing.
