Questions & Answers

As answered by people managing Authr and SEMRush.

Which are the primary technologies used for building your product?

Authr's answer

Python, FastAPI, PostgreSQL with pgvector, Redis and Celery, Playwright, React and TypeScript, Voyage AI embeddings, and large language models.

What makes your product unique?

Authr's answer

Most gap tools compare keywords, so one post on a topic counts as "covered". Authr counts how deep each blog goes on each topic. It reads your blog and up to 5 competitors' blogs, sorts every post into topics, and shows where rivals have several posts and you have none or one. Then it drafts the missing post in your voice, with internal links to pages you already have.

Why should a person choose your product over its competitors?

Authr's answer

Tools like Surfer, Clearscope and Frase help you optimize a post once you know what to write. Authr tells you what to write in the first place, based on what your actual competitors publish, then writes the draft. It also re-checks rival blogs twice a week and emails you when they publish something on your topics. Setup is two questions, and there's a 14-day free trial with no card.

How would you describe the primary audience of your product?

Authr's answer

B2B content teams and content leads running a company blog, and solo founders who write their own blog and need to know what to write next.

What's the story behind your product?

Authr's answer

We ran content gap analyses by hand on real company blogs, including all 529 posts on the Surfer, Clearscope and Frase blogs. Keyword tools called those blogs roughly even. Counting posts per topic showed each had clear gaps the others had already filled. Authr automates that analysis and writes the missing posts.
