The verdict: can you vibe code NeuronWriter?
You can build a solid personal-use clone of NeuronWriter's core writing editor and NLP term-matching engine, but handling robust live SERP scraping without getting blocked requires ongoing proxy and parsing maintenance.
Replicating the core loop—entering a keyword, fetching top competitor pages via Firecrawl, extracting key terms, and scoring a markdown document in real-time—is a fantastic 2-week side project using Next.js and Claude. However, building production-grade SERP scrapers that bypass anti-bot protections consistently will frustrate you, and you will spend significant time tweaking TF-IDF algorithms and prompt chains so the content scoring feels accurate rather than arbitrary. Unless you genuinely love SEO engineering, keeping your $23-$69/mo subscription is the rational economic choice.
Estimated effort: 2-3 weeks of part-time work
What you can't replicate
- Years of proprietary term weightings and historical content scoring data
- Deep native integrations with WordPress, Shopify, and Google Search Console

Build guide
01Scaffold Project and Database Schema
Initialize a Next.js application with TypeScript, Tailwind CSS, and shadcn/ui. Set up Turso database connectivity using Drizzle ORM and configure better-auth for single-user authentication.
Create a new Next.js project with App Router, TypeScript, and Tailwind CSS. Install shadcn/ui primitives (button, input, dialog, card, tabs, progress). Configure Turso for database connectivity with Drizzle ORM, defining schemas for 'projects' (id, name, target_keyword, created_at) and 'documents' (id, project_id, title, content, score, target_words, created_at). Integrate better-auth for secure email/password local authentication. Ensure all environment variables are correctly typed in a .env.example file.02SERP Scraper & Competitor Ingestion Pipeline
Implement a research module that accepts a target keyword, fetches top search results using Firecrawl, cleans the HTML into plain text, and extracts competitor headers and content lengths.
Build a backend API route in Next.js that takes a target keyword, invokes the Firecrawl API to discover and scrape the top 5 ranking URLs for that keyword, and cleans the resulting HTML into structured plain text. Extract all H1, H2, and H3 headers, total word counts, and compute basic term frequency statistics across the competitor corpus. Store these extracted insights in a new 'serp_analysis' table linked to the project.03NLP Term Recommendation Engine
Develop an algorithm that processes the ingested competitor text to generate a list of essential NLP terms, recommended word counts, and title/meta description guidelines.
Create a service module that takes the scraped competitor plain text and passes it to the Anthropic API using the Vercel AI SDK to extract key semantic terms, entities, and recommended usage frequencies. Format the output into a structured JSON list of recommended keywords with minimum/maximum frequency bounds, target word count ranges for the article, and suggested title/meta descriptions. Display these recommendations in a dedicated sidebar component within the dashboard.04Real-time Content Writer & Scoring Editor
Build a split-pane rich text writing editor where the left side is a markdown editor and the right side displays live content scoring and real-time term frequency highlights.
Build a dual-pane content writing screen in Next.js. The left side must be a responsive markdown text editor where users type their article draft. The right side must display a live content score (0-100) calculated dynamically based on word count progress and the frequency of required NLP terms extracted in Step 3. Implement real-time highlighting or checklist checkmarks next to each NLP term as the user includes them in the text.05AI Content Designer & Outline Generator
Add an automated article builder that generates complete paragraph outlines and structured sections using project context and SERP facts.
Implement an 'AI Content Designer' feature. Create a modal where users select their target project and keyword, trigger an AI call via Vercel AI SDK to generate a comprehensive H1-H3 article outline with fact summaries, and allow the user to insert the generated outline directly into their document editor with a single click. Support tone-of-voice selection (professional, casual, authoritative).06AI Visibility & Export Tools
Implement basic tracking for brand mentions across simulated search/LLM queries and add export options for Markdown, HTML, and clipboard copy.
Build an 'AI Visibility' tab that tracks brand query questions against simulated LLM answers using the Perplexity or Anthropic API, displaying a Share of Voice percentage table. Add export buttons above the content editor allowing users to instantly copy their optimized draft as Clean HTML, Markdown, or download it as a .docx file. Polish the UI with toast notifications and loading skeletons.
