An AI newsletter generator turns a description into a recurring newsletter. You say what it should cover, and AI agents find and read the sources, write each section, lay it out in a designed template and send it on a schedule. The useful ones keep the sources, structure and instructions visible, so issue thirty is as reliable as issue one.
That is a different job from the AI writing help inside email platforms, which drafts copy for you to edit and send. Full disclosure: Avos is our product. This guide walks through building a newsletter with it, from one sentence to a designed issue in the inbox, and then says plainly when an email platform is the better choice.
What is the difference between an AI newsletter generator and an AI writing assistant?
An AI writing assistant helps with the words. You still bring the content: you read the news, pick the stories, decide the angle, and the assistant tightens your draft or suggests a subject line. Every issue starts with you.
An AI newsletter generator brings the content. You describe the newsletter once, and every issue is researched and written from the sources you chose, then sent on schedule. You edit the system, not each issue. We compared that loop to vibe coding in Lovable for newsletters: describe it, see a real version, improve it by saying what is wrong.
How do you go from one sentence to a first issue?
Start by telling Avos's AI editor what you want, in plain words:
A weekly briefing for my team on grid batteries: new deals and funding, policy in the EU and the US, new research, and what people in the industry are saying. Mondays at 8, Berlin time.
From there the editor does the setup work:
- It plans the sections and picks sources. For that sentence: a news section on a news search for "grid-scale battery storage" plus trade feeds from the feed directory; a funding rounds feed for "energy storage"; research papers on "grid battery storage" from arXiv and PubMed; an X search for what the industry is saying; and a short text intro.
- It generates a preview. You read real output from today's sources before anything is sent.
- You refine it by chatting. "Drop US policy, add Australia." "Write the research section as one-line takeaways." "Lead with the biggest deal." The editor changes the sections and previews them again.
- It sets the schedule. Daily, weekly on the weekdays you pick, or monthly, at your time and in your timezone.
Prefer to start from something finished? The template gallery has ready-made editions with real sample issues, such as the Daily Brief, Tech, AI & Business and War & Conflict. Use one and reshape it with the same chat.
What can a section be?
A newsletter is an ordered list of sections, and each section has its own sources, filters, format, tone and language.
| Section | What it does | Example |
|---|---|---|
| News | Headlines or article briefs from the feeds you pick, each linked to its source | "Grid storage deals, five headlines" |
| AI | Writes from your prompt, with optional web search; on paid plans it can also make an image each time | "The week's most important number, explained in one paragraph" |
| Financial | Prices and daily changes for stocks, ETFs, crypto, forex and commodities, or US economic indicators | "Lithium, copper and three battery makers" |
| Portfolio | Your holdings, valued, with profit or loss | "My energy positions" |
| Text | Your own words: a heading, an intro, a sign-off | "A note from the editor" |
News sections can read many kinds of source: curated topics with wide international coverage, news searches, any RSS feed, web and AI search, X, YouTube channels, podcasts, research papers, funding rounds and company news. Where an AI news briefing gets its facts goes through each one, and the personal markets briefing guide shows financial sections in use.
How does a generated newsletter look?
Every issue is a designed newsletter, in the inbox and on the web, not a list of links in a chat window. You choose a layout for the newsletter (newsprint, tiles or outline), and the AI editor can design custom colors and fonts on top. Match a website goes one step further: paste your site's address in the newsletter's settings and Avos recolors the theme with your brand's colors and an email-safe font close to your own, with a preview before you save. The theme applies everywhere you read the issue, including the email.
Sections can carry a banner image: upload one, paste a link, or pick a photo from Unsplash. On paid plans an AI section can generate its own image each issue, such as a map of the week's hotspots. Financial sections render as clean tables, and in the web version you can open any asset's price chart. Every past issue stays in your archive.
The fastest way to judge the design is to read real issues: Markets & Investing, Crypto and Science & Health all show their latest issue.
Who can receive it?
By default, a newsletter goes to you alone. From the editor you can widen that:
- An audience. Add friends' or colleagues' email addresses and they get every issue; each can unsubscribe at any time. Turning the audience on makes the newsletter's page public to anyone with the link. How many recipients you can add depends on your plan.
- A public page with a subscribe form. Approved publishers can switch a newsletter to publisher mode: its public page collects subscribers, the Publisher tab shows subscribers and each issue's opens, and issues can be generated early so you can edit them or add a note, or held until you approve each one.
- Remix. Anyone reading a public newsletter can remix it into an Avos newsletter of their own.
Every issue ends with "How would you rate today's issue?" and a 1 to 5 scale. Your readers can rate it too (you can turn that off), and you see their ratings and notes, never who wrote them. The AI editor sees recent ratings as well: when they point at a problem, it suggests one change and makes nothing until you agree.
What keeps issue thirty as good as issue one?
A generator is only useful if it holds up on an ordinary Tuesday, months in. Avos has a few guards for that:
- No repeats. A story a section already delivered in a recent issue doesn't come back, and a story that appears in two sections of the same issue runs once.
- Quiet sections. When nothing new happened in a section's time window, the issue says so instead of padding it with old news.
- Feed health checks. Avos checks the RSS feeds in your sections every day; if one stops working you get an email, and the AI editor offers a replacement.
- Readable instructions. Every section's sources, filters, format and tone sit in its settings, so you can always see why an issue looks the way it does.
How does Avos compare with Beehiiv, Substack and Mailchimp?
They solve different problems. Email platforms help you write, send and grow a newsletter; Avos researches and writes each issue for you. Checked on 6 November 2026 against Beehiiv's pricing page, Substack's features page and Mailchimp's pricing page.

When is an email platform the better fit?
More often than an AI generator's marketing would admit:
- Your writing is the product. If readers subscribe for your voice, analysis and reporting, write it yourself. Substack is free to use and takes a 10% revenue share only when you earn from paid subscriptions.
- You want to grow and earn from a large list. Beehiiv puts an ad network, paid subscriptions and a referral program on its paid plans. Avos has no paid subscriptions for your readers and no ad network that pays you.
- You send marketing email for a business. Customer lists, campaigns and automated journeys are Mailchimp's home ground, with marketing automation flows on its paid plans.
Some writers use both: an Avos briefing as their private research desk, and an email platform for the newsletter they write themselves.
When is Avos the better fit?
- You want the newsletter to exist without writing each issue. A team briefing, a club's weekly roundup, a market note for yourself: the research and writing happen on schedule.
- You want news, data and analysis in one email. Headlines, market tables, your portfolio and AI-written sections sit side by side.
- Your readers speak another language. Issues can be written in many languages, per newsletter or per section, whatever language the sources are in.
- You would rather describe than configure. One sentence gets a first draft, and the chat does the rest. For a general morning email, see the daily news summary email; to turn feeds you already follow into one, see RSS feeds to a daily email briefing.
FAQ
Can AI write a whole newsletter for me?
Yes, if the newsletter is a briefing: Avos researches the sources you choose, writes each section with links back to the original reporting, designs the issue and sends it on schedule. If readers come for your personal voice and opinions, AI should help you, not replace you.
Is there a free AI newsletter generator?
Avos has a free Starter plan: you can build a newsletter with the AI editor and receive it on a schedule, with each issue using credits from the plan's monthly allowance. Paid plans add more credits and features; see the pricing page.
Can I send an AI-generated newsletter to my own subscribers?
Yes. Add recipients by email in the editor's Audience tab, and they can unsubscribe at any time. Approved publishers can also collect subscribers through a subscribe form on the newsletter's public page. Avos doesn't offer paid subscriptions for your readers.
Can I edit an issue before it sends?
You can preview and change sections at any time in the editor, and generate an issue on demand. In publisher mode, issues can be generated early so you can edit them or add a note before the scheduled send, or held until you approve each one.
Does an AI newsletter generator work in languages other than English?
Avos does. Each newsletter, or each section, can be written in the language you choose, and sources can be in any language. Ask the AI editor for "this whole newsletter in Spanish" or set the language in the settings.
