# Frequently Asked Questions

# Why do we need to supply our own OpenAI API Key?

To keep Marker Toolbox as a one-off payment on the Mac App Store, we have decided that if you want to use the ChatGPT features in Marker Toolbox, you'll need to supply your own API key.

This is mainly for privacy reasons, as it means you have full control over your own personal OpenAI account - rather than having one OpenAI API Key for all Marker Toolbox users.

It also means that if your OpenAI account has access to new OpenAI features (such as gpt-4-32k), that aren't yet publicly available, you can use them with Marker Toolbox.

You can set up a free OpenAI account, which gives you $5 in free credit that can be used during your first 3 months.

After the first three months, OpenAI charges per 1000 tokens. You can think of tokens as pieces of words, where 1,000 tokens is about 750 words.

Once you have a OpenAI account, you can generate API keys here.

# Does this work with any iPhone/iPad Logging Apps?

Yes, you can use third party iPhone apps, such as Timecode+.

Simply Share as Text in the Timecode+ App, then use the Paste button in Marker Toolbox to paste the text, and then Process Comments Locally.
