Grok Build is xAI's answer to Claude Code, Codex CLI, and Gemini CLI — a terminal-native, local-first coding agent that runs all code on your machine with nothing transmitting to xAI's servers. The headline feature: up to 8 parallel agents working on the same codebase simultaneously, each taking a different approach, letting you compare results. The "Arena mode" is distinctive: it pits multiple agents against the same task and presents the outputs side-by-side, letting you pick the winner. GitHub integration, a credits system, and an optional web UI round out the feature set. Currently in early access beta gated to Grok Heavy subscribers, with Elon Musk signaling a wider launch imminently. It powers grok-4.20-multi-agent under the hood — a model version specifically tuned for multi-agent coordination. Whether the 8-parallel-agent architecture produces meaningfully better code than a single focused agent remains to be benchmarked, but the concept is genuinely novel in the CLI agent space.

Recall
Find any file on your machine with a sentence — no tags, no indexing

Recall is a local-first multimodal semantic search tool that lets you find any file on your computer using natural language — images, PDFs, audio, video, and text — without any manual tagging, folder organization, or metadata. Ask "that invoice from the dentist last spring" or "photo of the whiteboard with the Q3 roadmap" and it surfaces the right file. Under the hood, Recall uses Google's Gemini Embedding 2 to generate semantic embeddings for all your files and stores them in ChromaDB, a local vector database that runs entirely on your machine. Nothing leaves your device. The Raycast extension adds a visual grid UI so you can search from anywhere on macOS without opening a terminal. First-run indexing can take 20-30 minutes for large libraries, but subsequent queries are near-instant. The project is MIT-licensed and built by a solo developer. It's a clear response to the frustration that Spotlight, Find, and Windows Search still rely heavily on filename and metadata matching even in 2026. As Gemini Embedding 2 is free within generous limits, the operating cost is essentially zero for personal use.
Reviewer scorecard
“8 parallel agents tackling the same coding task is a fascinating approach — it's basically tournament selection applied to code generation. If the arena mode lets me specify different constraints for each agent (test coverage vs. speed vs. readability), this could become a genuine creative tool for complex architecture decisions.”
“ChromaDB + Gemini Embedding 2 on local files is a setup I'd have spent a week configuring from scratch. Recall packages this cleanly with a Raycast extension that makes it actually usable day-to-day. The MIT license and zero vendor lock-in seal the deal for me.”
“It's still on a waitlist. Musk has said 'next week' about this launch multiple times across multiple weeks. The 'local-first, nothing leaves your machine' claim needs independent audit before trusting it for professional codebases. Approach with appropriate caution until it has a real public release.”
“Re-indexing after file changes, cold-start latency on large libraries, and the dependency on Gemini Embedding 2 (which isn't truly offline) are real friction points. Apple Intelligence already does some of this natively on-device. Wait for broader platform support before switching your file workflow.”
“The multi-agent arena pattern is prescient — the future of AI-assisted development is not one agent helping you, it's a tournament of agents generating approaches and humans curating outputs. Grok Build is sketching what software development will look like when compute is effectively free.”
“Semantic search for personal files is the foundation for personal AI agents. If your agent can find any piece of information you've ever touched, you unlock genuine memory at human-years scale. Recall is primitive but points at something important.”
“Even for non-developers, the arena concept translates well. Being able to prompt for a landing page, a marketing brief, or a piece of code and see 8 simultaneous interpretations is a genuinely powerful creative workflow. The 'pick the winner' UX pattern is intuitive and low-friction.”
“I have 80,000 photos, hundreds of PDFs, and years of Figma exports I can never find. The idea of describing an image or document and having it surface immediately is worth every minute of setup time. This is the dream of local AI finally shipping.”
