Turn Your Newsletter into a Carousel

Paste the web archive URL of your newsletter — Substack, Beehiiv, ConvertKit, Mailchimp, or any provider — into WaveGen. The AI reads the edition, pulls out the sharpest hook, the strongest arguments or stories, and the memorable lines worth quoting, and builds a carousel with headlines, supporting text, and AI-generated imagery. You can edit any slide in the visual editor, apply your newsletter's brand kit, and schedule the carousel directly to Instagram, LinkedIn, TikTok, Facebook, or YouTube. Two minutes start to finish.

WaveGen is purpose-built for newsletter-to-carousel workflows because it handles the full pipeline from URL to scheduled social post. Alternatives like PostNitro and Contentdrips are carousel editors — you still have to write the slide copy yourself, which defeats the point when your newsletter already contains the writing. aiCarousels extracts text from a URL but does not generate images or schedule. If you run a newsletter and want one paste-to-publish flow across Instagram, LinkedIn, and TikTok, WaveGen is the most complete option today.

Yes — any newsletter provider that publishes a public web archive works. Paste the URL of the archived edition (not the email itself) and WaveGen fetches the content. Substack and Beehiiv publish web archives by default. ConvertKit and Mailchimp require the archive to be made public in your settings. If the newsletter is subscriber-only without a public mirror, you can paste the text content directly in WaveGen's text input instead.

Yes. A single newsletter edition often contains 2–4 distinct themes — a main essay, a tips section, a recommendation list, sometimes a Q&A. WaveGen can generate separate carousels from the same URL by focusing on different sections, giving you multiple weeks of social content from one newsletter send. For longer editions (3,000+ words), this is the default way most newsletter creators use the tool.

Yes — this is the highest-leverage use case for newsletter creators on social. Instagram and LinkedIn carousels get significantly more organic reach than text posts with links, which means more cold-audience eyes on your content. When the first slide is a strong hook from your newsletter and the last slide is a soft subscribe call-to-action with a clear benefit, the signup rate from social-driven traffic is meaningfully higher than from a link-only post. Many newsletter creators treat social carousels as their primary top-of-funnel rather than as a secondary repurpose channel.

The newsletter-to-social-posts workflow produces a pack of platform-specific content — LinkedIn post, Instagram caption, TikTok text overlay, and more — from a single newsletter. This page focuses specifically on carousel output, which is the single highest-engagement format on both LinkedIn and Instagram. If you want one carousel optimized for swipe-through engagement, use this flow. If you want a full multi-format social pack, use newsletter-to-social-posts. The underlying AI extraction is the same.

Yes. WaveGen has a free tier with a monthly generation allowance that covers regular newsletter creators. Paste a URL, produce the carousel, edit in the visual editor, apply your brand kit, and download or schedule — all included in the free plan. Paid plans raise the generation cap, add priority processing, and unlock additional brand kits for writers running multiple newsletters or topic-specific newsletters under one umbrella.

Yes. WaveGen can read an English newsletter and produce the carousel in Spanish, French, Portuguese, German, Japanese, and many more languages. Useful for newsletters with international readership, or for creators publishing in English but wanting to reach non-English social audiences — a proven strategy for growing subscribers outside your primary language market.

The output leans on your source writing, so the voice tends to match your newsletter's tone. On top of that, WaveGen's brand kit lets you save a brand voice description that constrains the AI's stylistic choices — first-person or second-person, sentence-level cadence, vocabulary preferences, formality level. Newsletter creators with a strong voice typically find the first generation close enough to publish with small edits; after tuning the brand voice once, subsequent carousels get closer each time.
