Ghost Pepper is a macOS menu bar app that runs Whisper-based speech recognition and meeting transcription entirely on-device via Apple Silicon — no internet connection required, no audio leaving your machine. Hold Control to dictate into any text field; it transcribes and pastes the result in seconds. For meetings, it records calls and generates full transcripts, notes, and AI summaries saved as local markdown files. The app supports multiple model sizes from a 75MB fast model to a 1.4GB multilingual option covering 25+ languages. A local LLM layer (Qwen 3.5 variants) strips filler words and self-corrections from transcripts. The developer published a privacy audit confirming zero cloud API calls, tracking SDKs, or telemetry in the core functionality — an unusual level of transparency in this space. Built on WhisperKit and LLM.swift, Ghost Pepper requires macOS 14.0+ and Apple Silicon. It launched on Product Hunt today reaching #4 daily. For anyone running sensitive client calls, legal conversations, or just unwilling to feed voice data to cloud services, this fills a genuine gap that ElevenLabs, Otter.ai, and Whisper API don't touch.

Google AI Edge Gallery is a mobile app that lets anyone run powerful open-source LLMs — primarily Gemma 4 — directly on their Android or iOS device with zero internet connectivity. The April 2026 update brought full Gemma 4 support including the E2B edge variant optimized for sub-1.5GB RAM, alongside new Agent Skills that enable multi-step autonomous workflows entirely on-device. The app goes well beyond a chat interface. Users get Thinking Mode to watch the model's reasoning process in real time, multimodal features for image analysis and voice transcription, a Prompt Lab for experimentation, and Tiny Garden — an interactive game driven purely by on-device natural language understanding. Hugging Face integration lets users import custom models beyond the curated defaults. The significance of the April 7 release is timing: it dropped the same day as LiteRT-LM and coincides with Gemma 4's general availability, creating a complete stack from framework to end-user app. With 899 GitHub stars gained in a single day and app store availability on both iOS and Android, Edge Gallery is becoming the reference showcase for what on-device AI looks like in 2026.
Reviewer scorecard
“WhisperKit on Apple Silicon has gotten fast enough that local transcription is genuinely competitive with cloud services in latency. The Control-to-dictate UX is exactly right — no separate app to open. The privacy audit documentation is a rare and welcome move for an open-source tool.”
“The Agent Skills addition is the headline. Running multi-step agentic workflows on a phone with no API calls is something developers have been wanting to demo to clients. The Kotlin codebase is well-structured enough that it serves as a useful reference implementation too.”
“Apple Silicon only is a real limitation — no Intel Mac support, no Windows, no Linux. The meeting transcription accuracy will lag behind purpose-built cloud services like Otter or Fireflies that have years of model tuning. And the 1-7 second cleanup latency adds up in fast-paced conversations.”
“Even the E2B variant struggles on older devices and drains battery fast during extended sessions. The model roster is Gemma-heavy by design, which limits utility for developers invested in other model families. This is a showcase app more than a daily driver.”
“This is the inevitable direction: voice AI moving entirely on-device as hardware catches up to the task. Ghost Pepper is the leading edge of a shift where sending voice to the cloud will feel as strange as sending passwords to cloud storage does today. Apple's Neural Engine investment is paying dividends here.”
“Putting agentic AI in every pocket without a subscription or data plan is a genuine democratization moment. As mobile silicon improves, Edge Gallery represents where all smartphone AI is heading — the privacy and latency benefits of on-device will eventually make cloud-dependent AI feel antiquated.”
“The name is perfect — spicy, memorable, evokes both heat and ghostly invisibility (no data leaving). Menu bar apps with zero UI overhead are the ideal form factor for voice tools. The markdown output for meeting notes plugs straight into any PKM workflow.”
“Image analysis and voice transcription working fully offline is immediately useful on shoots or at events where connectivity is spotty. The Prompt Lab is a great scratchpad for refining prompts before committing them to a production pipeline.”
