Output.ai Examples

April 8, 2026 · View on GitHub

A gallery of production-ready AI workflows built with Output.ai — an open-source framework for durable, LLM-powered workflows orchestrated by Temporal.

Each workflow is a self-contained example you can run locally, learn from, and fork.

Workflows

Workflow	Description	APIs
blog_evaluator	Evaluate blog post signal-to-noise quality	Jina Reader
call_scorer	Score sales call transcripts against MEDDIC, BANT, or SPIN	LLM only
changelog_generator	Generate categorized changelogs from GitHub commits and PRs	GitHub
dependency_audit	Audit npm dependencies for vulnerabilities, licenses, and abandonment	GitHub, OSV, npm
recipe_extractor	Extract structured recipes from blog URLs	Jina Reader
url_summarizer	Summarize any webpage into TLDR, key points, and FAQ	Jina Reader
youtube_summarizer	Summarize YouTube videos with key moments and takeaways	YouTube
ai_hn_digest	Personalized Hacker News digest published to Beehiiv newsletter	HN, Jina Reader, Beehiiv
sales_call_processor	Process sales call transcripts into notes + parallel recipe analyses	LLM only

Prerequisites

Node.js >= 24.3
Docker and Docker Compose (for local development)

Getting Started

1. Install Dependencies

npm install

2. Configure Credentials

Output.ai uses encrypted credentials to manage API keys. To set up your own:

# Initialize a new credentials file and encryption key
npx output credentials init

# Edit credentials (opens in your $EDITOR)
npx output credentials edit

See config/credentials.yml.template for the full list of available credentials. At minimum, you need:

anthropic:
  api_key: "<your-anthropic-api-key>"

Some workflows require additional credentials — check each workflow's README for details.

Credential	Where to get it	Used by
`anthropic.api_key`	console.anthropic.com	All workflows
`github.token`	github.com/settings/tokens	changelog_generator, dependency_audit
`beehiiv.api_key`	app.beehiiv.com	ai_hn_digest

3. Start Output Services

npm run dev

This starts:

Temporal server and UI (http://localhost:8080)
PostgreSQL and Redis databases
Output.ai API server (http://localhost:3001)
Worker process for executing workflows

4. Run a Workflow

In a new terminal:

npx output workflow run blog_evaluator paulgraham_hwh

Each workflow has scenario files in its scenarios/ folder for quick testing.

5. Stop Services

Press Ctrl+C in the terminal running npm run dev to stop all services.
