Instapaper and ReadLoud both read text aloud, but they start from different assumptions about what you are trying to do. Instapaper is a read-later app with text to speech as one of its features. ReadLoud is a text to speech tool with nothing else going on.
What Instapaper actually offers
Instapaper lets you save articles, web pages and other reading material to come back to later, with a clean reading view, folders, and search. Basic text to speech, reading a saved article aloud, is free. Playlist-style listening, where saved articles queue up and play back to back like a podcast, is part of Instapaper Premium, priced at about $6 a month or $60 a year at the time of writing according to Instapaper's own pricing page. Instapaper also runs a Premium for Students tier at a lower price for people who qualify with a student ID.
This is a sensible design if listening is a secondary thing you do with articles you were going to save anyway. The free tier genuinely works for basic listening, which is more generous than most competitors offer for the same price of zero.
What ReadLoud actually offers
ReadLoud has no saving or organizing feature at all. What it has is text to speech itself, built out further than a bolt-on feature usually is: 30 voices across four engines, Fast, Studio, a preview engine called Gemini 3.1, and Narrator, built on Google's Chirp 3 HD voices for audiobook-style narration in 50 or more languages and locales. The Gemini-based engines take a delivery style, narrator, newsreader, calm, teacher, podcast host, storyteller, briefing, or a short custom instruction, so the same text can sound different depending on what you are listening to.
Word by word highlighting is measured from the actual generated audio using forced alignment, not estimated timing, so clicking any word jumps playback there accurately, and a sync slider lets you nudge it to personal taste. You can switch voices mid-document without losing your place, adjust speed from 0.5x to 4x with pitch preserved, and download the finished document as a single MP3 once it has generated. None of this requires saving the source article anywhere in ReadLoud first, you paste it, upload it, or link to it, and it plays.

| Main job | Save and organize articles, with reading and listening built in | Text to speech only |
| Basic listening cost | Free | Pay per minute, no subscription |
| Playlists / continuous listening | Premium feature, about $6/mo or $60/yr | Not a playlist model; play one document, switch voices mid-document freely |

Who suits which
If your habit is genuinely "save articles all week, listen to them casually on the weekend," and you do not care much about voice variety or precise highlighting, Instapaper's free tier does the job for nothing, and Premium's playlists are a reasonable upgrade if you want continuous listening across several saved pieces. There is no reason to pay ReadLoud for something Instapaper's free tier already covers well for your needs.
If you care about voice quality and choice, want to listen to things beyond saved web articles, PDFs, EPUBs, your own documents, research papers, or want highlighting that is actually synced to the real audio rather than an approximation, ReadLoud is built around exactly that, at the cost of paying per minute instead of getting it free.
The price math, briefly
Instapaper's free tier costs nothing for basic listening, so for light use it is genuinely hard to beat on price alone. Where the comparison shifts is scope: Instapaper only reads what you saved to Instapaper. ReadLoud reads anything you give it, so if your listening includes PDFs, EPUBs, or documents that never touch a read-later app, Instapaper's free tier simply does not apply to that material at all, and the comparison is not really about price at that point.
For a rough sense of where ReadLoud's pricing lands for genuine document listening, packs run from $9 for 60 minutes down to $99 for 1,000 minutes, and a full cost per hour breakdown works out favorably against a day of steady listening once you are past the free tier.
Being fair about the gap
ReadLoud does not have native apps, a browser extension, or built-in article saving, which are things Instapaper has spent years building well. If your workflow depends on Instapaper's saving and organizing as much as the listening, switching away from Instapaper for ReadLoud alone would be trading a real, working system for a narrower tool that does not replace what you would be giving up.
A note on what each one does with your files
Since Instapaper mainly handles saved web articles and ReadLoud handles a broader range of uploaded files, it is worth a quick word on what happens to what you give either one. On ReadLoud, there are no ads, no selling of data, and no training on your documents. Files you upload are deleted after the text has been extracted from them, and deleting a document later removes its generated audio and your listening progress along with it. Instapaper, as a saved-article service, operates under its own privacy terms, worth a look at instapaper.com directly if that matters for what you save there.
Using both
There is no conflict in keeping Instapaper for saving and its free listening for casual use, while reaching for ReadLoud specifically when you want to hear a PDF, an EPUB, or a document Instapaper was never going to save in the first place.
