Newsletter AI Agent is an open-source tool designed to fully automate the newsletter pipeline. It connects to your favorite RSS feeds or content sources, uses AI to extract and summarize the most relevant highlights, generates visually formatted email templates, and integrates with platforms like MailChimp or SendGrid. Users can customize topics, set delivery schedules, segment audiences, and review drafts before sending. With support for multi-language content and API-based extensibility, it scales from solo bloggers to enterprise marketing teams.

BlogSynth connects to the OpenAI API and automates blog post creation through a simple CLI interface. Users supply a title, a list of keywords, and tone preferences. The AI then generates a full outline, complete introduction, section headings, and conclusion. It supports word count limits, SEO-focused prompts, and markdown output for quick publishing. With customizable templates, BlogSynth can be integrated into workflows to produce consistent, well-structured content across multiple topics in minutes.
