Giststack
Turns the newsletters, sites and videos you follow into drafts in your voice
Giststack is a research-to-content workspace that collects the newsletters, websites and YouTube channels you follow, pulls out the insights inside them, and turns a chosen takeaway into a draft written in your voice.
It is built for people who already read widely but rarely publish: you add your own note on why an insight matters to your audience, and Giststack drafts a social post, video script, newsletter or longer article from it. The company lists founders, consultants, fractional leaders, executives, creators, business owners and agencies as its users.

What Giststack does
A reader for newsletters, sites and YouTube
Each newsletter gets its own Giststack email address, so you subscribe on the publisher's site and new issues arrive in your reader instead of your inbox. Websites can be added by address or RSS feed, and a YouTube channel can be followed for long-form videos, Shorts, or both kept as separate sources.
Insights and Stories
Insights pull the takeaways out of a single article, newsletter or video, while Stories group a theme across several publications you follow and score it. You choose the takeaway worth discussing before any drafting starts.
Drafts in several formats
A source or insight can become a social post or thread for LinkedIn, X, Threads, Facebook or Instagram, a video script, a newsletter, or a custom long-form draft such as a blog article. Every draft is yours to edit before it goes out.
Brand Profile and personas
The Brand Profile holds your audience, positioning and themes, and custom personas save your voice, tone, style and language as reusable presets. Brand Lens applies that context to each draft.
Private knowledge base
You can upload supported documents to a knowledge base that sits apart from the followed-source feed, so your own reports and notes can feed the same research and drafting workflow.
Publishing options
Pro and Business plans can publish posts with webhooks, and on any plan the LarkPulse add-on posts, schedules or queues to LinkedIn, X, Facebook, Instagram and Threads. Business also includes 500 MCP calls a month.

Popular for
Founders and consultants building a personal brand
For people who follow the right publications but never get from reading to posting. Giststack keeps the sources in one reader and produces a first draft you can revise and share.
Fractional leaders and executives
The product's own walkthrough follows a fractional CFO turning a story about outcome-based retainers into a LinkedIn post, using a note from their client work as the angle.
Agencies and teams
Pro and Business plans add multiple workspaces, so research and drafts for different clients or topics can be kept apart.
Video and podcast research
Follow YouTube channels, read transcripts and summaries with the original video nearby, and turn the material into a video script or written post.
