Ok, but Ghostreader *still* sucks
Unfortunately the Ghostreader feature (AI summaries) is a cheap open source model that costs $0.01 per month to run for their entire paid user base.
“Thinking” mode is so fast, I dread to think what “Fast” mode is.
Shame you can’t BYOK.

Update 2026-10-02: Still sucks. They shipped an update upgrading the model to GPT Luna. Tried it out - thinking mode summarized a 30 minute YouTube transcription on anthropology into a 10 line summary when asked to summarize.
I’ve been on the paid plan for 3 years now. They need to have models that adapt to the length and complexity of the item, otherwise these features are useless for anything other than summarizing a long tweet.

Hey there, thanks for your longtime support and for the candid feedback! The functionality you’re looking for is actually already available on web and desktop through Global Ghostreader. You can bring your own API key and use more powerful models for Ghostreader chats across your library or within individual documents. You can also use skills like "Advanced Summary" for longer, more in-depth summaries that are better suited to complex content. We’re currently working on bringing the same functionality to mobile. In the meantime, web and desktop are the best options when you want more control over the model and depth of Ghostreader’s responses. You can also configure automatic document-level prompts like “Summarize the document” to use your BYOK model and adjust the desired summary length. If you have any questions or run into trouble setting this up, feel free to reach out to us at hello@readwise.io!

Thanks for your candid feedback. Just so you know, you can add your own OpenAI API key at read.readwise.io/integrations to access higher ChatGPT models in Ghostreader and create automated prompts. For YouTube videos, if captions weren’t uploaded by the creator, Reader uses YouTube’s auto-generated transcript. For a cleaner version, use the enhanced transcript option (available via the “...” menu on mobile or document icon on web).
