Thanks for your feedback and I'm glad that the official extension works well for you. All I can say is you probably are not my target customers. Most of the time, the official extension doesn't work for me. And I'm not alone. You can check their recent reviews[0]. A lot of 1 star. I'm aware that there are other alternatives such as Push to Kindle, P2K, Instapaper, newslettertokindle etc. They provide much better conversion quality than the official extension, and better deliverability. I'm confident that KTool is on par with them, maybe better in some use cases (such as Twitter threads, HN, sending pdfs...). And their paid plans range from $2.99/mo to $10/mo. What I'm doing at KTool is to support all those content in a single subscription. I hate subscriptions, but until we found a better model, I can't sell it as one time payment. My expense is recurring (CPU for parsing & image processing, email + bandwidth to send articles to Kindle, Apple developer program, core parser maintenance as sites structure changes...) But I will definitely do more experiment with pricing though. Again, thanks for your valuable feedback.
