A free Kindle feature just got locked behind a subscription paywall ‣ Diverse Daily

Send to Kindle is arguably Amazon’s finest software addition to its line of e-readers. The feature stands as one of the only permitted gateways outside the company’s walled garden, allowing users to upload a wide variety of files to a portal that sends them right to their Kindle library.

While users like myself use it to download Substack articles and even AO3 stories for offline reading, some third-party apps and services utilize the feature and make it even more convenient — namely, Instapaper. Instapaper is a popular app that essentially lets you save articles and other web pages to read later, converting them into clean, distraction-free formats tailored for your e-reader’s display — for free.

Free for only a few more weeks, though. Instapaper announced that it was dragging the popular feature behind a paywall in February (but only for one category of users), and some Kindle owners are up in arms.

Instapaper’s Send to Kindle feature is becoming a premium perk

Locked behind $6 a month soon

Right now, and only for a few more weeks, Instapaper allows you to skip the steps that usually go with using the Send to Kindle portal (manually downloading and uploading the documents on your own). You can log into your Instapaper account on the e-reader you’re using and conveniently access the articles and web pages you’ve saved. But on February 19, 2026, all that convenience comes at a cost.

Instapaper’s Send to Kindle compatibility will become a Premium feature, available for a modest $6 per month or $60 per year subscription. It isn’t asking for your firstborn child, but many users are pointing out a painfully “unfair” point: only Kindle users will be paywalled — Kobo users will still have open access to the feature, according to Brian Donohue, Instapaper’s owner.

Why Send to Kindle specifically is going behind the paywall

The process isn’t cheap

The news — and surrounding discussion — made its way to Reddit, where some users expressed their appalled fury while others delightfully said they would be happy to opt into the subscription to maintain access to the feature. The discourse caught Instapaper’s attention, and Donohue jumped in with his own statement:

Generating Kindle digests is fairly resource intensive for us. It involves parsing a bunch of articles, downloading the images for each article, writing everything to disk, creating an ePub file, and emailing it to your Kindle email address.

The decision, it seems, wasn’t made on a whim. For years, he mentioned, Instapaper has offered the service for free to over a hundred thousand users — which adds up tremendously when it comes to all the processes above. Running any service at a loss isn’t good for business, and while it doesn’t seem “fair” that Kobo users still have access to the feature for free, it feels like Instapaper’s attempt to break even rather than a money-grab aimed at every single user. In fact, Donohue even says that “Kobo integration is based on [their] API, doesn’t require as [many] resources to run, and will remain free.”

One Redditor even responded to an irritated comment about losing the feature by prompting them to “ask Amazon to do it then — how can a third party keep doing it for free?” Another user replied to this with “advertising,” which fundamentally goes against Instapaper’s entire existence.

Getting upset with Instapaper as a business is futile — it’s not sustainable for anything to be operating at a deficit. However, it does prompt the idea that Amazon could make this process easier for either individual users or third-party apps in general. How, exactly, is up to the online giant itself.
