  Best-in-class terminal agent for scaffolding the full-stack Next.js application and writing complex prompt management logic

• Cursor

  Ideal for iterative UI tuning of the dashboard components and editor sidebar

Build guide

1. 01Project Scaffolding and Database Schema

   Initialize a Next.js project with Tailwind CSS, shadcn/ui, and configure Turso with better-auth for single-user authentication.

   Create a new Next.js 16 project using TypeScript, App Router, and Tailwind CSS. Install shadcn/ui primitives (button, input, select, dialog, tabs, dropdown-menu). Configure better-auth with a Turso (libSQL) database adapter to support secure email/password sign-in. Set up a clean dashboard layout with a collapsible sidebar for navigation between Templates, Document Editor, Custom Voices, and Settings. Ensure all environment variables are properly typed in a config schema.

2. 02Prompt Template Engine & 40+ Use Cases

   Build the template catalog database schema and UI selector allowing users to configure input variables for blogs, emails, ads, and social posts.

   Build a structured prompt template system in TypeScript. Create a database schema in Turso for templates (id, title, category, description, systemPrompt, inputFields json). Seed the database with at least 15 core use cases (e.g., Blog Outline, Email Reply, SEO Meta Title, Paragraph Generator, Social Caption). Implement a template selection page and a dynamic form generator that renders input fields based on the selected template's configuration schema.

3. 03AI Text Generation and Streaming Integration

   Integrate the Vercel AI SDK with Anthropic API keys to handle real-time text generation, streaming responses, and tone modifiers.

   Implement the AI generation backend route using the Vercel AI SDK and Anthropic API. Connect the template form submission to an API endpoint that constructs the final prompt by combining the template system prompt, user inputs, selected tone of voice (e.g., professional, casual, convincing), and target language. Enable streaming responses so generated text appears in real-time in the editor workspace. Add error handling for rate limits and invalid API keys.

4. 04Document Editor & Inline Text Editing Tools

   Build a rich text editor workspace with inline editing command toolbar (continue writing, expand, shorten, rephrase).

   Create a distraction-free document editor interface in the Next.js app. Add a floating or sidebar toolbar providing quick text manipulation actions: 'Continue Ryting' (autocomplete next sentences), 'Expand' (rewrite to be longer), 'Shorten' (summarize), and 'Improve Grammar'. Each action should send the selected text block to a dedicated AI backend route with specialized system instructions and stream the replacement or appended text directly into the active document.

5. 05'My Voice' Custom Tone Training Module

   Build the custom tone-of-voice manager where users can input writing samples to inject style instructions into generation prompts.

   Implement a 'My Voice' feature allowing users to create custom tone profiles. Create a database table for voice profiles (id, userId, name, sampleText, extractedCharacteristics). Build a settings screen where users paste writing samples, and use an LLM call to automatically analyze and summarize their style, vocabulary preferences, and sentence structure into a reusable style guide. Update the main generation API route to inject the active user's voice profile guidelines into the system prompt when selected.

6. 06Browser Extension Shell

   Build a Manifest V3 Chrome extension that communicates with the local or hosted Next.js app backend for quick text generation.

   Scaffold a Manifest V3 Chrome extension using TypeScript and Vite. Create a popup interface containing a mini template selector and text generator that calls your hosted Next.js API endpoints securely. Implement a content script that detects active text input fields on third-party web pages and injects a floating assistant icon, allowing users to trigger inline content generation and insert the result directly into the focused web element.
