MiniAi is a macOS menu bar app with exactly one job: explain selected text without breaking your focus. Highlight any text on your Mac — in a PDF, email, code file, web page, or document — press Option+Space, and a floating AI explanation panel appears. No app switching, no copy-paste, no context loss. Built by a medical student who needed to stay in reading flow while looking up terms in research papers, MiniAi uses Claude Haiku under the hood for fast, accurate explanations. The floating panel dismisses with Escape and leaves no trace in your task switcher. The scope is deliberately minimal: one gesture, one action, instant result. No chat history, no threads, no settings overwhelm. Free to use with your own Anthropic API key. Launched today on Product Hunt where it resonated strongly with students, researchers, and professionals who live in document-heavy workflows.

omi is an open-source AI platform from BasedHardware that runs continuously on your desktop and mobile devices, capturing screen activity, audio from meetings, and conversations in real time. It synthesizes everything into a persistent memory graph — you can later ask it what was decided in a meeting last Tuesday, what was on-screen during a debug session, or what a colleague said during a standup call. The platform spans macOS, iOS, Android, and even open-hardware wearable devices. The new v0.11.333 release (shipped April 18) adds significantly improved background processing, better MCP integration for feeding memories into coding agents, and a faster ChromaDB-backed retrieval layer. It claimed 824 new GitHub stars in a single day, the highest star velocity on GitHub trending this week. With 300,000+ active users and 10,000+ total stars, omi has quietly become the most widely deployed "always-on" memory layer for AI workflows. Its open hardware companion (a small wearable device) positions it beyond software into ambient computing.
Reviewer scorecard
“The Option+Space shortcut is muscle memory within 10 minutes. BYOK with Haiku means it's essentially free at typical usage — Haiku is fast and accurate enough for term lookups and quick explanations. The zero-UI-overhead philosophy is exactly right for a tool you invoke 20 times a day.”
“MCP integration is the killer feature here — being able to feed real-time meeting context directly into your Claude Code session without copy-pasting is something I've wanted for two years. The 824 stars in one day tells you this resonated with real developers immediately.”
“Apple's own Writing Tools in macOS 15 already has a 'Summarize' action in the right-click menu, and it's free with no API key. PopClip has been doing triggered text actions for a decade with a rich ecosystem of extensions. MiniAi needs a clearer differentiator beyond the keyboard shortcut.”
“Continuously capturing your screen and all audio is a massive privacy surface. Most workplaces explicitly prohibit recording meetings without consent, and storing that data locally doesn't make the capture part legal. Proceed with caution and check your employment contract.”
“Tools like MiniAi are training users to expect ambient AI assistance — intelligence available at any moment without mode-switching. This behavioral shift is significant: once people get used to instant contextual explanation, the bar for every reading and research tool permanently rises.”
“This is what a true second brain looks like — not a note-taking app, but a persistent ambient layer that captures life as it happens. The open-hardware wearables angle is early but points to a world where your AI context travels with your body, not just your laptop.”
“The story behind MiniAi — built by a med student to stay in flow during paper reading — is authentic and the design reflects genuine user empathy. For writers, researchers, and anyone working with dense material, this is the kind of tool you install and forget you installed because it just works.”
“For content creators who reference past work, client calls, and visual research constantly, having an AI that already has all that context without being explicitly fed it is genuinely transformative. Auto-generating meeting summaries and action items alone saves hours per week.”
