You subscribe to more newsletters than you can actually read. Readless fixes that. Point your email newsletters, Substack publications, and RSS feeds at one place, and get back a single AI digest on the schedule you set.

Instead of ten separate emails, you get one briefing. Readless reads across everything you follow, merges stories that several sources cover, strips out ads and tracking pixels, and groups what's left by topic. Every item links back to the original when you want to go deeper.

You control the depth. Concise gives you quick bullets; Detailed keeps more context. Follow a German newsletter or a Chinese Substack and still read it in English, or pick any of nine languages for your digest.

Run separate digests for the parts of your life that don't overlap: one for work, one for investing, one for the tech you follow. Each has its own sources, delivery time, and settings.

Pro is $4.90/month and covers newsletters, Substack, RSS, custom depth, and up to 3 digest schedules. Max is $9/month and adds two things: the Synthesis briefing, which reads every source and writes one connected editorial story instead of separate summaries, and custom instructions that steer the tone and focus of each digest. Max also raises the schedule limit to 8.

Every account starts with a 7-day Pro trial. A card is required to start, and you're only charged when the trial ends. We never sell your data, and no human reads your newsletters.

Readless features and specs

  • One digest from newsletters, Substack, and RSS
    Point email newsletters, Substack publications, and RSS feeds at one place and get a single briefing back, instead of checking each source separately.
  • Synthesis editorial briefing (Max)
    Reads every source you follow and writes one connected story with citations back to each one, rather than ten stacked summaries.
  • Cross-source de-duplication
    When several newsletters cover the same story, Readless merges them into one item and links each source, so you don't read the same thing four times.
  • Ad and clutter removal
    Strips ads, tracking pixels, and footer noise before the digest reaches you.
  • Digest languages
    Read a source in any language and get the summary in yours. Auto keeps each source in its own language; pick a single language to unify everything.
  • Custom summary depth
    Choose Concise bullets or Detailed context, set per schedule.
  • Custom summary instructions (Max)
    Steer the tone and focus of a digest in up to 2,000 characters per schedule.
  • Multiple digest schedules
    Split work, investing, and personal reading into their own briefings, each with its own time and sources. Up to 3 on Pro, 8 on Max.
  • Private newsletter address
    A dedicated @mail.readless.app address collects your newsletters and keeps your personal inbox clean.
  • Flexible delivery control
    Pick the weekdays and delivery time for each digest, morning, noon, or evening.

Questions & Answers

As answered by people managing Readless and CodeFactor.io.

Why should a person choose your product over its competitors?

Readless's answer

RSS readers like Feedly collect your sources but still make you read everything. Inbox filters move newsletters into folders without shortening them. Readless does the reading for you: it summarizes, removes duplicate coverage, and delivers one digest on your schedule. It handles email newsletters, native Substack, and RSS in the same place, writes in nine languages, and lets you run separate digests for separate parts of your life. Pro is $4.90/month; Max adds the Synthesis briefing and custom instructions for $9.

How would you describe the primary audience of your product?

Readless's answer

People who follow more than they can keep up with. That includes investors tracking market newsletters, engineers and founders following tech Substacks, operators watching several industry briefings, and anyone whose inbox has quietly turned into a backlog. If you subscribe to 10, 30, or more newsletters and open only a fraction of them, Readless is built for you.

What's the story behind your product?

Readless's answer

It started with a full inbox and a simple problem: subscribing to good newsletters is easy, but keeping up with them is not. The writing you actually wanted gets buried under senders you meant to read and stories you already saw somewhere else. Readless was built to turn that pile into one short, organized read you finish, so following a source doesn't cost you an hour a day.

What makes your product unique?

Readless's answer

Most tools stop at collecting your feeds or summarizing one email at a time. Readless reads across everything you follow at once. It merges stories that several newsletters cover, strips the ads, and organizes what's left by topic, so you read one briefing instead of twenty emails. On Max, the Synthesis option goes a step further and writes a single connected story across all your sources, with citations back to each one. You can also read any source in your own language, out of nine options.

Readless Reviews

  1. Honestly saved my mornings

    Was subscribed to like 12 newsletters and never actually read any of them. Felt bad about it every morning. Forwarded everything to Readless about two months ago and now I just get one email at 7am with the stuff that actually matters.

    Setup was painless. The summaries are better than I expected, it skips the sponsor blocks and the long personal intros and just gets to the point. I still click through when something looks interesting but most days I am done in 5 minutes.

    Only thing is the design heavy ones lose a bit in summary form, but not a dealbreaker for me.

    Pros: one email instead of a pile, summaries don't feel lazy Cons: visual newsletters don't translate as well
