AI-Powered
What if your newsletter wrote itself? Slackletter uses AI to analyze your Slack conversations, identify the best content, and generate polished newsletters—automatically, in your brand's voice.
No credit card required. Powered by Claude Sonnet 4.5.
Most newsletter tools still make you do all the work: find content, write copy, format everything, then send. You might get some templates or a drag-and-drop editor, but you're still starting from a blank page every time.
AI tools exist that can write content, but they don't know your business. They don't know what your team actually accomplished this week, what links your engineers shared, or what customers are celebrating.
The best content for your newsletter is already being created—in Slack. You just need AI that can find it and package it.
Slackletter is an AI agent powered by Claude Sonnet 4.5 that lives in your Slack workspace. It reads your selected channels, understands the context, and identifies the content most worth sharing with your audience.
Then it writes a complete newsletter draft—structured, formatted, and voiced in your brand's style. Links get enriched with descriptions. Updates get framed as benefits. Wins get celebrated.
Not AI-generated content from nothing. AI-curated content from your actual team's work.
The AI reads recent messages from your selected Slack channels, understanding context, relevance, and importance.
It identifies the most newsletter-worthy content: announcements, shared links, wins, interesting discussions—while filtering out noise.
Using your content instructions and brand context, the AI writes a complete newsletter draft—structured, formatted, and ready to review.
Request changes in natural language: "make it shorter," "add more about the product launch," "sound more casual." The AI revises until you're happy.
The AI knows your business, audience, and newsletter style—generating content that sounds like you, not a robot.
Shared URLs are automatically enhanced with titles, descriptions, and context—no manual formatting required.
The AI distinguishes between newsletter-worthy content and casual chatter, focusing only on what matters.
Chat with the AI to revise drafts. Each version improves based on your feedback—learning your preferences over time.
You control exactly which Slack channels Slackletter can access. We only read the channels you explicitly share—never private channels or DMs without permission.
We never store your Slack messages. Content flows through the AI to generate drafts, but we only keep the newsletters you create. Your team's conversations stay private.
