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.
Response from developer
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). If you need help, feel free to reach out to us at hello@readwise.io.

Best Read Later App - Hands Down
really good crossplatform app but the reader is very limited in terms of features
I really would have liked to make Readwise my media library for all my content with note taking associated (for articles, books epub and pdf, videos, podcasts), but the reader isn’t customizable enough yet (same flaw as Notion, except this app is supposed to be dedicated to reading).
For now, I’m using Readest (open source) to host my books, with iOS/Mac/Windows sync. But I’d really appreciate being able to migrate my books to Readwise reader, given all its cutting-edge features and versatility.
Good, falls behind other ePUB readers.
absolutely worth it
when I first started using Reader, I was between jobs. when my (already generous) free trial ended, they extended it by three more months for me + were highly responsive to emails. I did not feel like a random user; the Readwise team has repeatedly made me feel like a human. (I’ve now paid for the yearly subscription two years in a row, and I tell people how great this app is all the time.)
another feature I love is having the ability to select the voice for the audio reader. I am hard of hearing with an odd kind of hearing loss. low pitched and especially high pitched voices are difficult for me to understand, so whether I can easily listen to an audiobook or podcast is dependent on the voice type. in Reader, I selected a voice that works great for me, so now I can listen to anything I can save. huge accessibility win.
there are many other features I love as well. being able to search through things I’ve read all in one place is an amazing feature, among others.
this is also one of the only apps where I actually appreciate the AI integration (even beyond the voice readers). ghostreader doesn’t feel forced on me, but it’s there for the occasional time I find it useful.
I could go on, but I have some reading to do.
I’m starting law school next year and SO glad I found this app before beginning.
If this app exists for the rest of my life and the interface design + functionality stays this good, you’ve got a lifelong subscriber. I have major gratitude for the Readwise team.
the ONE thing that would make this app even better for me is a Kobo (ereader) integration. if it had a Kobo integration, I’d officially call it the perfect app. I love the physical experience of reading on my Kobo rather than phone or tablet, and I wish I could save articles to Reader, read on my Kobo, and have my highlights sync up.
overall, 5/5 app FOR SURE.
Revolutionized how I consume media
Wow!
I LOVE IT SO MUCH!! Using it on laptop and phone !
Thank you devs!!
