Question 1

What is Spanreedr?

Accepted Answer

Spanreedr is a newsletter builder that uses AI to research content across YouTube, Substack, blogs, and news, then writes draft sections in your voice. You edit in a drag-and-drop editor and publish — with clear labels showing what's AI and what's yours.

Question 2

How does the AI content research work?

Accepted Answer

You define keywords and topics for your newsletter. Spanreedr searches YouTube, Substack, blogs, and news to find the most relevant articles, videos, and posts. Each result includes a relevance score, summary, source link, and publication date. You then generate formatted newsletter sections from these results as link lists, summaries, or digests.

Question 3

Does Spanreedr replace human writing?

Accepted Answer

No. Every newsletter can include both AI-generated sections and content you write yourself. The editor lets you mix and match freely. Most creators use Spanreedr for research-heavy sections like weekly roundups while writing personal insights and commentary themselves.

Question 4

How does voice matching work?

Accepted Answer

Upload writing samples — past blog posts, emails, social threads, or newsletters — and Spanreedr analyzes your tone, sentence structure, vocabulary, and punctuation to build a voice profile. AI-generated content uses this profile so the output sounds like you. The system also learns from your edits, improving accuracy with each issue you publish.

Question 5

How is AI content marked in newsletters?

Accepted Answer

Every content block in a Spanreedr newsletter is clearly labeled with its origin: AI-generated, voice-matched, or human-written. You can also add inline annotations — personal notes where you share your own take on AI-researched content. This transparency helps build trust with your readers rather than eroding it.

Question 6

Can I publish to Substack or Beehiiv from Spanreedr?

Accepted Answer

Yes. Spanreedr integrates with Substack and Beehiiv for cross-publishing, so you can manage your newsletter in Spanreedr and push it to your existing platform. You can also cross-post summaries to X (Twitter) and LinkedIn, or use custom webhooks to send content to any external service.

Question 7

Does Spanreedr have an API?

Accepted Answer

Yes. Spanreedr offers a REST API, an MCP server for AI agent workflows, and a CLI for terminal-based management. All interfaces use scoped API keys with granular permissions for newsletters, issues, content generation, subscribers, voice profiles, and webhooks.

Question 8

Is there a free plan?

Accepted Answer

Yes. Once approved from the waitlist, you can start on the Free plan with 1 newsletter, up to 100 subscribers, 20 AI content searches per month, and 4 issues per month with basic voice matching. The Pro plan removes these limits and adds platform integrations, developer API access, advanced voice matching, and priority support.

Question 9

Who is Spanreedr built for?

Accepted Answer

Solo founders, indie makers, and independent creators who want to publish research-driven newsletters every week but don't have hours to spend on each issue. Especially useful if you already publish on Substack or Beehiiv and want to keep your cadence without burning out.

Question 10

What content sources does Spanreedr search?

Accepted Answer

Four source types: YouTube (videos and channels), Substack (newsletters and posts), blogs (articles from across the web), and news (recent coverage). You choose which sources to include for each keyword, and results are scored by relevance so you see the most useful content first.
