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.

Rowboat
AI coworker that builds a local, inspectable knowledge graph from your work

Rowboat (YC S24) is an open-source AI coworker that connects to your email, calendar, and meeting notes, then builds a persistent knowledge graph stored as plain Markdown files on your local machine. The graph is fully inspectable — it's just a folder of .md files you can open in Obsidian, edit, or commit to git. Using this local knowledge graph, Rowboat helps draft emails in your voice, prepares meeting briefs before calls, generates docs and summaries, and answers questions about your work history. It supports MCP (Model Context Protocol) for connecting external tools like GitHub, Linear, and Notion. Runs entirely on your machine with no data sent to external servers beyond your LLM API calls. The key differentiator is transparency. Unlike AI memory systems that store knowledge in opaque vector databases or cloud embeddings, Rowboat's knowledge graph is human-readable at every step. You can audit what it knows about you, delete specific facts, and understand exactly why it drafted an email the way it did.
Reviewer scorecard
“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.”
“Inspectable Markdown-based memory is the right call. I can version-control the knowledge graph in git, grep through it, and actually understand what context my AI assistant has — that's more than I can say for any SaaS memory product. MCP support means it plugs into my existing toolchain.”
“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.”
“Self-hosted means you're on your own for setup, sync, and maintenance. Most people using AI coworker tools want them to just work — and polished competitors like Mem.ai and Notion AI have months of production hardening. The Markdown vault is clever but also fragile at scale.”
“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.”
“Persistent, user-owned AI memory stored as plain text files is the foundation of truly personal AI assistants. When models can be swapped and knowledge graphs can be exported, you break vendor lock-in completely — Rowboat is building the right abstraction layer for the long term.”
“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.”
“Having an AI that actually knows my past projects, writing style, and client relationships — stored in files I control — is exactly what I've wanted. Email drafting in my own voice based on real context beats generic ChatGPT outputs every time.”
