How accurate are the AI summaries?
Readless only summarizes what is actually in the original — it never invents or fabricates information. The system is tuned to preserve specific facts (numbers, names, dates, direct quotes, attributions, and explicit claims) while compressing filler, intro padding, and repeated context. Every digest entry links directly to the full original newsletter, so you can verify any detail in one click. Most users find that key insights, data points, and action items pass through faithfully while ad/sponsor blocks and boilerplate are removed.
What's the difference between Concise and Detailed summaries?
Concise summaries provide quick bullet points highlighting the most critical information—perfect for busy professionals who want to scan quickly. Detailed summaries offer more context and explanation while still being significantly shorter than the original newsletters. Most users save 85-90% of their reading time with either style.
Can I change my digest schedule?
Absolutely! You can adjust your digest schedule anytime. Choose which days of the week to receive digests and what time works best for you. Pro users can create multiple schedules—for example, a daily digest for urgent industry news and a weekly digest for in-depth analysis.
Does Readless work with all newsletters?
Readless works with virtually all text-based email newsletters. We handle both plain text and HTML newsletters, extracting and summarizing the main content while filtering out ads, tracking pixels, and promotional elements. If a newsletter is primarily images or PDFs, those won't be summarized but will still be accessible in your dashboard.
Can I exclude certain newsletters from my digest?
Yes! Pro users can create sender filters to control exactly which newsletters appear in each digest. You can also suppress specific senders entirely if you want to keep them but not include them in any digest.
Does Readless work with Substack?
Yes — natively. Open the Sources tab and choose 'Connect Substack' (or use the matching option in the setup wizard). Paste any Substack handle (@name), profile URL, or publication URL and Readless connects it as a Substack source — not a generic RSS feed. If the author runs multiple publications, you'll see a picker so you can select which to add. Each connected Substack appears with its own Substack mark in your Sources list, and free + paid posts flow into your digest with AI summaries.
How does Readless handle the same story showing up in multiple newsletters?
When several newsletters cover the same launch, study, or news event, Readless detects the overlap and merges them into a single summary that combines insights from every source. Instead of reading the same story 3-5 times across your subscriptions, you get one synthesized item with links to every newsletter that covered it. This typically removes 30-40% of redundant reading at high subscription volumes.
