Frequently Asked Questions
What is Brain Memory?
Brain Memory provides a hierarchical, file‑system‑based memory system for AI coding agents, modeled on human neuroscience concepts such as decay, recall strengthening, and associative networks. The memory is organized as a directory tree, allowing agents to browse and edit memories with any file explorer, avoiding opaque embeddings. Memories follow an exponential forgetting curve and are reinforced through spaced recall, with weighted edges linking related items for spreading activation. A hosted MCP connector lets the same memory store be used by Claude Code, Codex CLI, OpenCode, Copilot CLI, Kilo, Antigravity, and Claude & ChatGPT apps, so agents can switch models without losing learned information. Sync is achieved via plain files in a folder that can point to Google Drive, Dropbox, iCloud, git, or encrypted export, requiring no account. The system records provenance for each memory, applies deterministic scoring using TF‑IDF and decay factors, and runs a nine‑phase nightly consolidation cycle that includes replay, pruning, and REM‑style recombination. Benchmarks show the architecture outperforms BM25 and vector embeddings under noisy conditions. GateOnAI Score: 60/100.
What is MetaGPT?
MetaGPT is an open‑source multi‑agent framework that enables AI agents to collaborate, plan, and execute projects as a single team. Built in 2023, it lets users describe an idea with one prompt and orchestrates the entire software development cycle from design to deployment. The technology was productized as MGX, a full‑stack creative engine that earned #1 Product of the Day on Product Hunt, and further evolved into Atoms, a complete commercialization engine that turns concepts into profit‑ready businesses with optimized workflows and an intuitive design. Atoms offers a free tier with 15 daily credits and paid Pro and Max plans starting at $20 and $100 per month, respectively, providing higher usage limits, accuracy, and storage. GateOnAI Score: 73/100.
