Dune is a tiny CNC-machined anodized aluminum keypad (40×10×10mm, 50g) from Project Mirage that ships three programmable physical keys alongside context-aware AI logic — automatically detecting your active macOS app and updating key assignments with no manual setup. It's the closest thing yet to a physical MCP client. The hardware handles the meetings problem elegantly: one-click join for Zoom, Teams, and Google Meet with calendar sync, dedicated mic/camera toggles, and instant meeting-window focus. But the broader promise is context adaptation: keys that behave differently when you're in your editor vs. your browser vs. your design tool, without you needing to define profiles. USB-C powered, macOS only, shipping in May 2026 with early bird pricing. Project Mirage has 8+ years of hardware experience and the form factor is genuinely minimal — a sliver of machined metal on your desk rather than another chunky macro pad. The open question is how deep the context awareness goes and whether the AI layer is smart enough to be useful rather than occasionally wrong and annoying. Early Product Hunt reception was strong (608 votes, top of leaderboard), suggesting there's real appetite for physical AI interfaces.
Infrastructure

Stash is an open-source persistent memory infrastructure for AI agents built on PostgreSQL and pgvector. Unlike retrieval-augmented generation, which searches static documents, Stash actively learns from agent experience — consolidating raw observations into facts, relationships, causal links, and higher-order patterns over time. The system exposes 28 MCP tools covering the full cognitive stack: episode storage, fact synthesis, entity graph management, goal tracking, failure pattern recognition, and self-correction when contradictions emerge. It deploys via Docker Compose in three steps and works with any OpenAI-compatible API — Claude, GPT, local models via Ollama. Hierarchical namespaces let agents keep user facts separate from project facts separate from self-knowledge. This fills a real gap in the agent ecosystem. Most agent frameworks treat each session as stateless, which means agents repeat the same mistakes and lose hard-won context. Stash gives agents a persistent cognitive layer that compounds. It surfaced on Hacker News this week to notable developer interest and is worth watching as MCP adoption accelerates.
Reviewer scorecard
“The primitive here is dead simple and correct: an HID device whose key mappings are driven by a macOS accessibility API hook watching the frontmost application — the AI layer handles the mapping logic so you don't write profiles by hand. That's the right DX bet. The moment of truth is day two, not day one: does the context inference hold up when you have twelve apps open and you're alt-tabbing between your editor and a Slack thread? If the answer is yes, this is the macro pad I'd actually leave plugged in. The specific decision that earns a ship from me is that they rejected the 'define every profile yourself' pattern that killed every Stream Deck workflow I've ever set up.”
“The 28 MCP tools are the right abstraction level — my Claude Desktop agents can now actually remember what I've told them across sessions without me writing my own memory layer. The Docker Compose setup is clean and the pgvector backend is production-ready.”
“Direct competitor is the Stream Deck Mini plus a $10/yr Keyboard Maestro license, which already does context-aware macro switching with zero AI ambiguity. The specific scenario where Dune breaks is the one that happens constantly: two apps open side-by-side, ambiguous context, and three keys that do the wrong thing because the model guessed wrong — that's worse than a dumb macro pad, not better. What kills this in 12 months is Apple shipping Focus-mode-aware Shortcuts automation natively in macOS 16, at which point the software layer this hardware depends on is commoditized. To earn a ship: show me six months of real-world context accuracy data, not a Product Hunt leaderboard.”
“The consolidation pipeline sounds elegant in theory but in practice you're letting an LLM synthesize 'causal links' and 'higher-order patterns' from raw observations. That's a recipe for hallucinated beliefs that compound over time. I'd want rigorous testing before trusting this in any production agent.”
“The thesis Dune is betting on: within three years, AI context awareness will be accurate enough that zero-configuration physical controls outperform manually-configured ones, and users will pay a hardware premium for that. That's a falsifiable claim riding a specific trend line — on-device app-state inference getting cheap enough to run as a background daemon — and Project Mirage is early, not late, to it. The second-order effect nobody is talking about: if this works, it inverts the macro pad market from a power-user niche into a normie peripheral, because the configuration tax that kept civilians away disappears. The future state where this is infrastructure is a desk where every physical control knows what you're doing without being told.”
“Persistent memory is the missing piece between 'AI assistant' and 'AI colleague.' Stash's self-correction and failure pattern recognition are early implementations of what agents will need to become genuinely reliable over long time horizons.”
“The job-to-be-done is singular and clear: stop context-switching your hands when your screen context already switched. The meetings use case is the product's sharpest edge — calendar sync plus one-click join plus mic/camera toggles is a complete workflow replacement, not a feature — and that alone justifies the purchase for anyone on four-plus calls a day. The product has a real opinion: it decides your key assignments, you don't. That's brave and almost certainly right. The gap that would turn this ship into a skip is if the broader context-awareness layer — editor vs. browser vs. design tool — turns out to be shallow window-title matching dressed up as AI; ship the meetings story hard and make everything else a bonus.”
“Finally an agent that remembers my brand guidelines, tone preferences, and past feedback without me repeating myself every session. The namespace hierarchy means I can have separate memories for different clients.”
