Substack Reader, within the Substack app, gives you a place to read subscriptions, discover writers and join conversations. Readless emails scheduled summaries of eligible newsletters and connected feeds. Choose by whether you want full reading and community, summary-based triage, or a combination of the two.
The Substack app is free; paid publications charge separately. Readless Pro is US$4.90/month and Max is US$9/month, billed monthly in USD. Public feeds and forwarded emails do not grant access to every paid post.
Eligible new accounts can try Pro for 7 days with a payment card. Cancel before the trial ends to avoid a charge. Max is a paid plan, not automatically included in the Pro trial.

The Substack app guide describes a subscription queue, paid and saved filters, a chronological latest view and archiving. Discovery, Notes and subscriber conversations let you find writers and participate alongside reading. Use the Substack app when those activities are the reason you open a publication.
Full posts preserve the author's argument, examples and qualifications. Choose them for an essay you want to discuss, evidence you need to inspect or a publication you support. A summary can help select a post, but it does not replace its community or guarantee that important context survives.
Substack's September 26, 2022 web Reader announcement explicitly offered outside publications through external RSS. Treat that as historical web-reader documentation; check your current app or web interface for the source and platform you need. It does not establish arbitrary email-newsletter intake or identical support across all current clients.
Pro includes Concise and Detailed summaries of individual eligible sources on up to 3 schedules. Optional Hot Topics can highlight a specific story covered by at least two distinct newsletter senders; source summaries remain separate.
Paid Max adds up to 8 schedules, optional Synthesis and custom instructions. Synthesis is a thematic briefing with source references. Check the references and available originals when a conclusion matters; a citation is not a guarantee that every claim or source is covered correctly.
Select sources, sender filters and delivery settings for each schedule. You might keep essays for a weekend read and receive summaries of other eligible issues during the week. AI, promotion filtering and repeated-story detection can omit or misstate material. Readless does not automatically organize, archive or delete messages in your external mailbox.
See optional Max Synthesis or how Readless works for the output formats and source setup.
Readless can receive newsletters at your assigned Readless address and process connected Substack or RSS sources. Forward from a mailbox you control where permitted, or change a publisher's delivery address if supported. Confirm receipt before relying on that path; Readless does not provide a general migration of saved Substack posts, a reading queue or conversations.
A paid subscription stays with the publisher. Content must be received or accessible and eligible for processing. Public feeds can expose excerpts or free posts rather than complete paid articles. A source connection does not bypass a paywall, fetch every paid post or import all past issues. Processing limits and source availability can affect which items appear.
Open publisher links where available for a deeper read. Received newsletter emails are available in the dashboard while stored, subject to retention limits and your publisher access. Keep important originals where permitted and review the privacy policy and terms before relying on the service as a record of an issue.
Choose it for following writers, reading posts in full, finding new publications and joining conversations. Use its reading filters to return to a saved issue or see recent posts. Your paid subscriptions determine access.
Consider Readless if you want text summaries to help pick what to read across eligible sources. You can keep the Substack app for full posts and community. There is no subscription-count threshold or guaranteed reading-time result; compare the output with your own needs.

Yes. You can keep the Substack app for full posts, discovery and conversations, then use Readless to triage eligible newsletter emails or connected feeds on a schedule. This is a workflow you can choose, not a requirement to move every subscription. Compare a representative summary with its available original before deciding what you want to read in full.

Substack's September 26, 2022 web Reader announcement explicitly offered external RSS subscriptions. That is historical web-reader evidence, not a guarantee of the same current interface on every platform or arbitrary email-newsletter intake. Check your current app or web interface for the input you need. Readless accepts received newsletters and connected Substack or RSS feeds, subject to source access, eligibility and processing limits.
Readless does not provide a general import of a Substack reading queue, saved posts or conversations. For future digests, connect an accessible Substack or RSS source, change a publisher delivery address where supported, or forward newsletter emails from a mailbox you control where permitted. Confirm receipt and the resulting digest. Connecting a source does not import its entire archive or guarantee a delivery time.
Choose the Substack app when full posts, your subscription queue, discovery and community are central to your reading. Consider Readless when you want scheduled summaries to help select material for a deeper read. Neither a source count nor a fixed reading-time saving determines the right choice. Setup, source volume and the checking you need affect the work involved.
Readless can summarize eligible content it receives or can access, including newsletter text you receive under a paid subscription and forward where permitted. Publisher subscriptions and permissions remain your responsibility. Public feeds may contain only free posts or excerpts; a connection does not unlock a paywall, retrieve every paid post or recover a complete archive. Source links remain subject to publisher access, and received emails are available in the dashboard while stored under retention limits.
The Substack app provides discovery, subscriptions, Notes and subscriber conversations alongside reading. Its guide describes paid, saved and latest filters, including a chronological latest view. Readless focuses on summaries of sources you select and can access; it does not replace a publication's comments, conversations or full-post experience. You can retain the app for those activities.
There is no required subscription threshold. Try a representative set of material you already read, compare the output with originals and include setup, checking and subscription costs in your decision. Full reading may fit a few important essays; scheduled summaries may help you choose what to open across other sources. Neither workflow guarantees complete coverage or better recall.
Yes. Pro supports up to 3 schedules and Max up to 8, with selected sources, sender filters and delivery settings for each. Use separate schedules for different subjects or reading times. Summarization, promotion filtering and repeated-story detection can miss material; they do not ensure that every source or relevant detail appears.
Keep full posts and community where they matter to you. Add scheduled summaries if they help you select material for a deeper read, and check their limits against the sources you use.
