1. Go to latest release
2. Download and extract the archive
3. Place the binary/executable in some directory
4. Add that directory to $PATH

Setting API keys

To use the app, you will need to set OPENAI_API_KEY or/and GEMINI_API_KEY, OPENROUTER_API_KEY env variables depending on your needs

API keys guide

OpenAI APIs

Set up your openai api key:

• ChatGPT: how to get an api key
• Mistral: how to get an api key

export OPENAI_API_KEY="some-key" # you would want to export this in your .zshrc or .bashrc

Gemini API

Set up your api key - how to get an api key

export  GEMINI_API_KEY="some-key" # you would want to export this in your .zshrc or .bashrc

OpenRouter API

Set up your api key - how to get an api key

export  OPENROUTER_API_KEY="some-key" # you would want to export this in your .zshrc or .bashrc

Stdin piping

You can pipe input into the app and do things like this:

cat PROMPT.md | nekot -p openai -u http://localhost:11434 -m gpt-oss:latest -n

Web search (BETA)

Web search feature uses tool calling for web search reqests exectution. This feature can be toggled using Ctrl+w.

Details

• Uses the DuckDuckGo and Brave search engines and requires no configuration
• Results are scored using bm25 for better accuracy
• Using web search can significantly increase token usage

Config

We provide a config.json file within your directory for easy access to essential settings.

• On MacOS & Linux, the path is ~/.nekot/config.json.
• On Windows, the path is C:\Users\%UserName%\.nekot\config.json or %HOMEPATH%\.nekot\config.json

Example

{
  "providerBaseUrl": "https://api.openai.com", // Or http://localhost:11434, or any other OpenAi compatible API
  "systemMessage": "",
  "defaultModel": "",
  "colorScheme": "groove", // pink, blue, groove
  "provider": "openai", // openai, gemini, openrouter
  "maxAttachmentSizeMb": 3,
  "includeReasoningTokensInContext": true,
  "sessionExportDir": "/must/be/absolute/path/to/exports"
}

• providerBaseUrl: The url can be anything that follows OpenAI API standard ( ollama, lmstudio, etc)
• chatGPTApiUrl [obsolete]: same as providerBaseUrl
• systemMessage field is available for customizing system prompt messages. Better to set it from the app
• defaultModel field sets the default model. Better to set it from the app
• maxAttachmentSizeMb field sets maximum allowed image size
• includeReasoningTokensInContext field sets whether to include reasoning tokens in the next request or not.
• sessionExportDir allows to specify directory for session exports. If not set, exports are saved to current directory. The path must be an absolute path

Providers

You can change API provider using the provider field.

Available providers:

• openai default
• gemini
• openrouter

To use GeminiAPI, just set "provider": "gemini" (make sure to set GEMINI_API_KEY env variable). When using the gemini or openrouter providers, providerBaseUrl param is not used.

Themes

You can change colorscheme using the colorScheme field.

Available themes:

• groove default
• pink
• blue

Data migration

If you need your settings and chats on other machine - simply copy chat.db and config.json from the .nekot/ directory and paste to the same directory on other machine.
