# Hexai

![HexAI Small Logo](hexai-small.png)

Hexai, the AI addition for your Helix Editor (https://helix-editor.com) .. Other editors should work but weren't tested.

It has got improved capabilities for Go code understanding (for example, create unit tests from function), but other programming language work as well.

## Features

* LSP AI Code auto-completion
* LSP AI Code actions
* LSP in-editor chat with the LLM
* Stand-alone command line tool for LLM interaction
* Parallel completions and CLI responses from multiple providers/models for side-by-side comparison
* TUI AI code-action runner (`hexai-tmux-action`) with Bubble Tea
  - Includes a "Custom prompt" action (hotkey `p`) that opens your editor (`$HEXAI_EDITOR` or `$EDITOR`) on a temporary Markdown file.
* Tmux popup editor (`hexai-tmux-edit`) for composing longer AI agent prompts
  - Opens `$EDITOR` in a tmux popup, pre-filled with the current prompt text
  - Auto-detects Claude Code, Cursor, Amp, Aider, and other agents
  - Config-driven: add new agents via `[tmux_edit]` in config.toml
* Support for OpenAI, OpenRouter, Anthropic, and Ollama
