A Flyletter alternative for newsletter writers
Flyletter builds a brand profile from three writing samples, then drafts the issue with images and social posts. HeyNews trains on the issues you have already sent, watches your sources, and uses what readers open and click.
What it is
HeyNews is an AI newsletter writer for operators who run a real publication. It connects to beehiiv, Kit, Substack, Ghost, Mailchimp, or any newsletter with a public archive, imports your recent issues (up to 50 from a public archive) to build a Voice Profile, monitors your sources (RSS, blogs, social profiles, Reddit, saved articles), scores stories against your audience, and drafts your next issue. You review it and send from your existing platform.
Flyletter is an AI newsletter platform for people who publish their own newsletter. It stores a brand profile built from three writing samples, then seven specialist agents take an idea to a finished draft with images and social posts, according to Flyletter's features article (checked October 15, 2026). Six content specialists plan, research, structure, draft, edit, and illustrate, and a separate step turns the issue into social posts, according to Flyletter's homepage (checked October 15, 2026). You review the draft, and an export does not send it, according to Flyletter's features article (checked October 15, 2026).

Use cases
The weekly writer who also needs the social posts
Flyletter's Publicist writes posts for LinkedIn, X, Threads, and Substack Notes from the finished issue. If that bundle is the job, Flyletter is set up for it. HeyNews stops at the newsletter draft.
The Kit publisher who is tired of pasting
On a paid Flyletter plan, an API key plus one click creates the draft in Kit. HeyNews connects to Kit with OAuth and imports your archive. You still copy the finished HeyNews draft into Kit.
The beehiiv operator who wants the draft in beehiiv
Flyletter's homepage describes beehiiv export through Claude, while its features article lists direct API-key export. Confirm the current workflow with Flyletter. On a paid beehiiv plan, HeyNews can create the finished draft in beehiiv as an unsent post.
The operator with a long back catalog
Three samples are enough for Flyletter to build a profile. HeyNews reads the issues you already sent, up to 50 from a public archive, and uses that Voice Profile on the next draft.
FAQ
Does HeyNews replace Flyletter?
For the newsletter draft, it can. Flyletter also writes social posts and images, and on paid plans it can create a draft in Kit. HeyNews trains on your sent archive, monitors sources, and on paid beehiiv plans can create an unsent draft in beehiiv. Keep Flyletter if you want the social posts, the images, or the Claude connector.

On paid plans, the homepage lists Kit export by API key and beehiiv export through Claude and beehiiv's MCP connector, according to Flyletter's homepage (checked October 15, 2026). Its features article instead describes direct API-key draft export to beehiiv, Kit, and WordPress, according to Flyletter's features article (checked October 15, 2026).

For Kit and those archive platforms, you copy the finished HeyNews draft in.
Does either tool publish the newsletter for me?
No. Flyletter's software exports create drafts; nothing is sent or scheduled. Auto-write leaves a draft with a "Written!" badge for you to review, according to Flyletter's features article (checked October 15, 2026). HeyNews does not send or publish either. You send from your platform.
