Voice2Sub: Local AI Desktop Subtitle Generator
Voice2Sub is a desktop AI subtitle and transcription app built to generate subtitles and transcripts from local video and audio files without uploading media to browser tools. Published May 21, 2026, the app uses Whisper AI recognition for speech-to-text, runs on Windows x64, macOS Apple Silicon and Linux x64, and supports hardware acceleration (CUDA on compatible Windows/Linux, Metal on Apple Silicon). Voice2Sub exports common subtitle and transcript formats (SRT, VTT, TXT, LRC, CSV) and provides users control over model selection and transcription settings. The project is available via a website, downloadable releases, and a GitHub repository.
Announces a small desktop AI tool for local subtitle/transcript workflows; useful for creators and privacy-focused use cases but not industry-shifting.

Open-source Local Meeting Transcription App for macOS
A developer built Scripta, an open-source macOS app that records dual-channel meetings (microphone + system audio), transcribes both streams entirely on-device, and generates AI summaries without cloud requests. The app uses whisper.cpp with Metal GPU acceleration to transcribe microphone audio and Apple’s SFSpeechRecognizer for system/remote audio captured via ScreenCaptureKit. Scripta integrates with a local Ollama instance for streaming summary generation (default model qwen2.5:3b). The post documents engineering details: building a static whisper.cpp library, Swift bridging, a 5-second sliding-window transcription strategy, handling Voice Processing IO quirks (unexpected 9-channel mic format and audio ducking), and distribution via GitHub Releases with a curl-based installer rather than the App Store.
Bandicam Unveils AI Transcription Feature for Mac Users
Bandicam Company has released an AI-powered Video-to-Text transcription feature in Bandicam for Mac that converts spoken audio from screen recordings and MP4 files into searchable transcripts and subtitle (.srt) or text (.txt) files within seconds. The built-in system supports multiple languages, automatic language detection, and offers user controls such as a search box, subtitle toggles, audio preprocessing to reduce noise, and model cache management. Users can select AI model presets (Tiny, Base [default], Small, Medium, Large Turbo) and regenerate transcripts. The feature is available now in the latest Bandicam for Mac release and is positioned to streamline workflows for content creators, educators, students and business users who need captions, meeting notes or indexed video content.
Vmake Labs Launches AI Video Translator
Vmake Labs announced the AI Video Translator, a modular workflow inside its editor that combines translation, caption management, dubbing (with voice matching and cloning options), lip sync, and up-to-4K video enhancement. The product targets creators, marketers, e‑commerce teams and video studios by enabling multilingual versions of existing videos without rebuilding assets. Teams may use only subtitle translation or combine dubbing, voice personalization and lip sync for full localization. The workflow supports 14 languages and is designed to reduce handoffs between separate tools, speeding turnaround and scaling localization. The announcement was published via GlobeNewswire on MarTech Series on June 29, 2026.
