Developer-Tools

Crush represents Charmbracelet’s entry into the AI coding assistant space, bringing their signature terminal-first philosophy and “glamourous” design aesthetic to AI-powered development. Built as a native terminal application, Crush distinguishes itself through its exceptional multi-model support, flexible configuration options, and deep integration with developer workflows through LSP and MCP protocols.

Core Features

Terminal-First Design

• Native CLI Experience: Fully optimized for terminal workflows with keyboard-driven interaction
• Cross-Platform Support: First-class support on macOS, Linux, Windows (PowerShell and WSL), FreeBSD, OpenBSD, and NetBSD
• Minimal Resource Footprint: Lightweight Go-based implementation with fast startup and response times
• Session Management: Multiple work sessions with context preservation per project

Multi-Model Architecture

• Provider Flexibility: Choose from Anthropic, OpenAI, Groq, OpenRouter, Google Gemini, Cerebras, HuggingFace, VertexAI, Amazon Bedrock, and more
• Custom Provider Support: Add your own OpenAI-compatible or Anthropic-compatible APIs
• Model Switching: Switch LLMs mid-session while preserving context and conversation history
• Cost Tracking: Built-in cost tracking and token usage monitoring

Enhanced Context Awareness

• LSP Integration: Uses Language Server Protocol for additional context, just like modern IDEs
• MCP Support: Extensible via Model Context Protocol (stdio, http, and sse transport types)
• Project Initialization: Analyzes codebase and creates context files for future sessions
• Git Integration: Native support for version control workflows with attribution options

Technical Specifications

Quick Setup

Crush runs great with no configuration. Simply set an API key for your preferred provider:

Eleanor Berger shares the terminal tools she uses alongside Claude and other CLI agents.

GitHits is an AI-powered code search platform that provides short, focused, verified code examples from global open source repositories. It helps developers solve specific problems by delivering canonical code solutions rather than overwhelming them with options.

Context7 is a specialized AI platform designed to provide coding agents and developers with rapid access to current library documentation and API references. It acts as a librarian subagent, intelligently searching through repositories and documentation sites to gather relevant context before development work begins.

Grokipedia represents a revolutionary leap forward in knowledge management—combining the power of AI with human judgment to create a dynamic, self-correcting encyclopedia that evolves in real-time. Launched in October 2025, Grokipedia isn’t just an updated Wikipedia; it’s a fundamentally new approach to building and maintaining the world’s most accurate source of truth.

Core Features

• Transparent Correction Process: Shows what was wrong, why it was wrong, and what got fixed
• Continuous Learning: AI improves with each human interaction and correction
• Version History: Complete traceability of all changes and improvements

Interactive Fact-Checking System

• Line-by-Line Highlighting: Users can flag any specific content for review
• Contextual Feedback: Add detailed context and reasoning for corrections
• Real-time Collaboration: Watch as AI processes and incorporates human insights
• Multi-Perspective Analysis: Considers multiple viewpoints before making corrections

Human-AI Knowledge Partnership

• Human Judgment: Provides nuance, context, and ethical considerations
• AI Processing: Delivers speed, scale, and pattern recognition capabilities
• Collaborative Intelligence: Combines strengths of both human and artificial intelligence
• Quality Assurance: Multi-layered review process ensures accuracy

Technical Specifications

• Platforms: Web-based platform with mobile optimization
• API Access: RESTful API for integration with development tools and applications
• Real-time Processing: Sub-second response times for content reconsideration
• Version Control: Complete edit history with change tracking and attribution
• Privacy: User data protection with transparent content policies
• Scalability: Cloud-native architecture supporting global user base

Unique Advantages

Transparent Knowledge Evolution

Unlike traditional encyclopedias that present information as static facts, Grokipedia shows the journey of knowledge—how discoveries are made, corrections are implemented, and understanding evolves over time. This transparency creates a learning environment where users understand not just what to think, but how knowledge itself develops.

Grokipedia 0.1 is an AI-powered knowledge platform with real-time fact correction, offering an open alternative to Wikipedia.
