Description

Muse Code is a beta terminal coding agent from Meta designed to help developers complete complex software engineering work across large codebases. Powered by Muse Spark 1.2, the agent can plan repository changes, write code, run validation steps, and coordinate persistent subagents for difficult development tasks. Muse Code uses a simple main agent loop supported by async background agents that remain active throughout each session. These background agents can gather information, carry out next steps, and decide when to report back to the main agent, reducing latency and unnecessary user steering. The runtime is built around a local event log where every model call, tool run, approval, and edit is appended. This event log makes Muse Code replay-exact and restart-safe, allowing it to resume from the point of failure after a crash. Muse Code also ships with default skills, including /plan, /grill, and /goal, to support structured planning, plan validation, and objective completion. It can be installed on macOS or Linux and is integrated with Meta’s AI developer ecosystem. By combining terminal-based coding, persistent subagents, replay-safe execution, bundled skills, and Muse Spark 1.2, Muse Code helps developers automate larger and longer software engineering workflows.

Description

NarrativAI is designed specifically for writers who create original characters, expansive universes, and large ensembles that can be challenging to manage mentally. It stands out from typical AI writing tools for two main reasons. First, the OC Vault serves as a continuity engine that automatically develops as you write, analyzing your drafts to extract key details about your characters, setting, and timeline without requiring you to keep a separate record. This system ensures that any contradictions in your writing are flagged before they can escalate throughout your narrative. Second, Muse, the collaborative writing partner, remains transparent in its operation, always indicating whether it is in Listening, Suggesting, or Drafting mode, so you can understand its influence on your fictional world and the reasoning behind any changes. Additionally, two new modes, Safety Checking and Resting, will be introduced as the product evolves. At present, we are excited to present a special Founding Member offer to the first 100 individuals who sign up, which includes lifetime Premium access, a package of 50,000 credits, an exclusive permanent badge, and a guaranteed locked-in rate for the future. This is a fantastic opportunity for aspiring writers to enhance their creative process.
