Cai (⌥C) is a macOS utility that runs AI actions on anything — selected text, clipboard content, active app context — with a single keyboard shortcut, entirely locally. It ships with Ministral 3B bundled, so it works offline out of the box with no API key, no account signup, and no network requests. For developers who prefer their own stack, it also connects to Ollama, LM Studio, Apple Intelligence, and OpenRouter. Beyond text transformations, Cai acts as a local automation layer: it can open GitHub issue drafts in your browser, create Linear tickets from selected text, run custom shell scripts, and chain multiple actions together. The whole thing is MIT licensed and open source. The UX is intentionally minimal — no chat interface, no persistent window — just a quick invocation overlay that appears, acts, and disappears. The positioning is clear: Cai competes with productivity tools like Raycast AI and PopClip, but wins on the privacy angle. There's no vendor seeing your prompts, no subscription creep, and no dependency on internet connectivity. For developers, writers, and researchers working with sensitive content who want AI assistance without cloud exposure, Cai fills a real gap that bigger AI apps can't — or won't — fill.

Recall 2.0 is a personal AI knowledge base that ingests everything you read, watch, or listen to — articles, PDFs, YouTube videos, podcasts — and automatically builds a knowledge graph from it. The pitch: "When AI gave everyone the same brain, we give AI yours." Instead of chatting with a generic LLM, you chat with one that's grounded in your actual reading history and interests. Version 2.0 adds meaningful new capabilities: you can now bring your own LLM (customizable model selection), connect via MCP for programmatic access, and use a "Listen Mode" that converts your saved content summaries into audio with cloneable voices. Spaced repetition surfaces things you've read at the right time to reinforce retention — blending a knowledge manager with a learning tool. The differentiator from plain note-taking apps like Obsidian or Notion is the automatic enrichment: Recall summarizes, tags, and links content without you doing the organizational work. The v2.0 bet is that your saved knowledge becomes genuinely useful for AI conversations rather than just sitting in a searchable archive.
Reviewer scorecard
“I set up Cai with a custom action to take a stack trace from my clipboard and open a pre-filled GitHub issue in 10 minutes. The Ollama backend means I can use a larger local model when I'm at my desk and fall back to Ministral 3B on the go. MIT license means I can fork it and add my team's internal tools.”
“MCP integration in v2.0 is the feature developers will care about most — it means you can pipe your Recall knowledge graph into Claude or other agents as context. That's a genuinely new primitive: personal knowledge as a live tool call, not just a static export.”
“Ministral 3B is fine for basic text tasks but it stumbles on anything requiring real reasoning or domain knowledge. Most users will hit its limits quickly and need to set up Ollama anyway — which is a non-trivial setup process for non-developers. The privacy story is genuine but the capability bar is lower than what cloud alternatives offer.”
“The knowledge base graveyard is littered with tools that people love for two weeks and then forget to use. Recall only works if you're consistent about saving content, and most people aren't. The value compounds over time, which is also when people are most likely to have stopped using it. It's a habit tool masquerading as a knowledge tool.”
“Cai represents a class of tools that become dramatically more useful as on-device models improve. When Bonsai-scale 1-bit models hit 8B+ quality at 131 tokens/sec locally, Cai's architecture is exactly right — a minimal, composable action layer on top of local inference. The MIT license means the community will build the plugin ecosystem.”
“This is the personal context layer that makes AI actually personalized. Right now LLMs know everything except what makes you specifically interesting. A knowledge graph of everything you've ever read, combined with a good retrieval system, is the missing piece for truly personalized AI assistance.”
“I've been looking for a way to do quick AI rewrites and tone adjustments in any app — not just in a web browser — without pasting things into a chat interface. Cai works in Figma, Notion, Miro, everything. The local privacy angle matters a lot when I'm working on client content that's under NDA.”
“The Listen Mode that turns your saved summaries into audio is underrated for creative people who commute or exercise. Being able to review your own curated knowledge in audio format — with a voice you can customize — is a genuinely novel way to stay connected to research without screen time.”
