Quick start

This guide walks through installing Seepient, configuring your first provider, and running a prompt across the interactive TUI, the CLI, and the TypeScript SDK.

Step 1: Install Seepient

Install the package globally using your preferred package manager. Seepient requires Node.js 22.19 or higher.

Homebrew (macOS / Linux)

brew tap hashangit/seepient
brew trust hashangit/seepient
brew install seepient

pnpm

pnpm add -g seepient

npm

npm install -g seepient

Verify the installation:

seepient --version

Step 2: Configure your providers

Run the interactive setup wizard:

seepient setup

The wizard discovers supported models from upstream catalogs, lets you input credentials (pasting an API key, linking an environment variable, or signing in via OAuth), and assigns default models for common tasks.

Alternatively, export your API key in your current shell environment:

OpenAI

export OPENAI_API_KEY="sk-..."

Anthropic

export ANTHROPIC_API_KEY="sk-ant-..."

Google Gemini

export GEMINI_API_KEY="..."

Step 3: Run the interactive TUI

Run seepient without arguments to start the full-screen terminal interface:

seepient

You can type prompts in the input box at the bottom. The TUI streams the response token by token, renders markdown tables and code blocks, and shows an approval dialog when the model requests permission to execute a shell command or mutate a file.

Press Ctrl+C or type /quit to exit.

Step 4: Run a one-shot command from the CLI

To run a prompt directly without opening the interactive interface, pass the prompt string as an argument:

seepient "Inspect this directory and list any package.json scripts"

For non-interactive automation in shell scripts or CI pipelines, add the -y flag to automatically approve actions:

seepient -y "Run test suites and print a failure summary if any fail"

You can also pipe standard input directly to the agent:

git diff | seepient "Review this diff for missing test cases and edge cases"

Step 5: Use the TypeScript SDK

Install the SDK locally in your project:

pnpm add seepient

Create a file named agent.ts:

import { createSeepient } from 'seepient'

const agent = await createSeepient({
  provider: 'anthropic',
  model: 'claude-sonnet-4-6-20260320',
})

const response = await agent.chat('Explain what this repository does based on its README.md')
console.log(response.text)

Run the script with Node.js or tsx:

npx tsx agent.ts
