Let ChatGPT annotate Omnivore articles for you

Overview

This serverless function can be used to automatically add annotations to Omnivore articles when a specific label (say, "summarize") is added to them. It uses Omnivore's API and webhooks as well as OpenAI's chat completions API.

How to Use

See this article for detailed instructions: https://blog.omnivore.app/p/using-chatgpt-to-automatically-add

For most convenience, deployment using Vercel is recommended. Theoretically it could work on other serverless functions providers but I have only tested it with Vercel. Vercel offers a free hobby plan that should cover basic usage of this function.

Deploy the example using Vercel:

Vercel Setup

When adding the repo to Vercel, set the environment variables to make the APIs work and allow customization.

• OMNIVORE_API_KEY (required): omnivore.app --> API Key
• OPENAI_API_KEY (required): platform.openai.com --> API Keys
• OMNIVORE_ANNOTATE_LABEL (optional): set this to the name of label you want to use to trigger processing. Example: "Summarize" (without quotes). Use colons to seperate label variants e.g. naming a label "Summarize:outline" will match the environment variable value "Summarize". Not required if you use the PAGE_CREATED Omnivore webhook event type which process every article added to Omnivore.
• OPENAI_PROMPT (optional): the instruction that's send to OpenAI's GPT model in addition to the article content if no label description has been entered. Uses the label description from Omnivore if available.
• OPENAI_MODEL (optional): the model name to use. Defaults to "gpt-4o-mini" (without quotes).
• OPENAI_SETTINGS (optional, advanced): additional request parameters send when generating the chat completion. Use JSON. Example: {"temperature": 0, "seed": 1234}.

Deploy and copy the URL of your deployment.

Omnivore Webhook Setup

In Omnivore add a new webhook and set the URL to the deployed Vercel function URL from the step above and add the path /api/annotate to it. Example: https://projectname.vercel.app/api/annotate

If you have defined a label name to listen for in the step above, then select LABEL_ADDED as event type. If you want the function to process every article you add to Omnivore, then instead select PAGE_CREATED.

Now either add a new article to Omnivore or your label to an existing article. Within less than a minute, the response of the model's completion should appear in the notebook of the article.

Check the runtime logs if you encounter issues. Check your API keys and never share them publicly.

Development

Clone and Deploy

git clone https://github.com/jancbeck/omnivore-ai-annotations

Install the Vercel CLI and dependencies:

npm i -g vercel
npm i

Then run the app at the root of the repository:

vercel dev

API Endpoints

• POST /api/annotate: Annotates an article with an AI generated response.

Local testing with Postman

1. Local Testing: Vercel offers a local development environment using the vercel dev command. Run this command in your project directory.
2. Postman Setup: Open Postman and create a new request. Set the request type to whatever your function expects (likely POST or GET).
3. Request URL: Use http://localhost:3000/api/annotate as the URL, replacing 3000 with whatever port vercel dev is using.
4. Send Request: Click "Send" in Postman to trigger the function.

Observe the response and terminal output for logging information.

Ideas

• use individual article highlights to allow "chatting" within Omnivore (e.g. highlight text, add note "explain" and GPT will generate the highlight with a reply based on the prompt and context.
• instruct the model to highlight the article for you via function calls. Perhaps using the article notebook as an instruction input.
