The verdict: can you vibe code Decktopus?
You can build a solid personal subset featuring prompt-based deck generation, layout rendering, and basic export, but the automated brand scraper and real-time AI delivery coach will require tedious debugging.
Creating a personal presentation generator is entirely feasible using Next.js, Tailwind, and LLM structured outputs. However, getting HTML/CSS layouts to export cleanly into native, editable PowerPoint (.pptx) files without broken text frames or misaligned graphics is a notoriously painful engineering hurdle. Furthermore, building a real-time speech coaching loop with filler-word detection and pacing analysis requires wiring up audio streaming, transcription models, and latency optimization that will eat up several weekends.
Estimated effort: 3-4 weeks of focused building

Build guide
01Project Scaffolding & Database Schema
Initialize a Next.js project with Tailwind CSS, set up Turso with Drizzle ORM, and configure better-auth for user management.
Scaffold a new Next.js 16 application with TypeScript and Tailwind CSS. Set up Turso database connection using Drizzle ORM with tables for 'users', 'presentations' (id, userId, title, themeJson, createdAt), and 'slides' (id, presentationId, layoutType, contentJson, orderIndex). Implement better-auth for email/password authentication with a clean login and registration page.02AI Presentation Generation Engine
Build the backend service that calls the Anthropic API with structured output instructions to convert a prompt into a multi-slide presentation schema.
Create an API route at /api/generate-deck that accepts a presentation prompt and slide count. Use the Anthropic API with JSON mode to generate a structured array of slides, where each slide specifies a layout type (e.g., 'hero', 'split', 'bullets', 'stats'), title, body points, and optional image prompts. Store the generated presentation and its slides in Turso, then redirect the user to the editor view.03Dynamic Slide Layout & Editing Canvas
Develop the interactive slide editor frontend with modular layout components and real-time prompt-based editing.
Build a slide editor dashboard in Next.js featuring a sidebar slide navigator and a main canvas area. Create modular React layout components for 'hero', 'split', 'bullets', and 'stats' layouts that render dynamically based on slide content JSON. Add an 'Edit with AI' floating input box on each slide that sends a modification prompt to an API route, updating the specific slide's content in real-time.04Brand Kit & URL Extractor
Implement a brand kit feature that parses a company website URL to extract primary colors, fonts, and injects them into presentation styling.
Implement a Brand Kit settings page where users can input a company website URL. Create a server action that fetches the target webpage HTML, extracts the dominant theme colors from meta tags or inline styles, and saves the palette to a user_brands table. Apply these brand colors and font selections dynamically via inline CSS variables across all presentation slide components.05Export Pipeline (PPTX & PDF)
Integrate export capabilities allowing users to download their presentation as a PowerPoint (.pptx) file or PDF document.
Install 'pptxgenjs' and implement an export API endpoint or client-side handler that translates the presentation slide JSON structures into a downloadable .pptx file, mapping titles, text blocks, and background colors accurately. Also include a print-optimized CSS view and jsPDF/html2canvas integration to support clean PDF exports from the browser.06Loop AI Delivery Coach (Rehearsal Mode)
Build a rehearsal mode interface using browser speech recognition APIs to track pacing, word count, and provide feedback.
Create a presentation delivery and rehearsal view called 'Loop'. Use the browser's native SpeechRecognition API to transcribe the user's spoken rehearsal in real-time. Display a live timer, word count per minute (pacing metric), and a simple feedback summary panel evaluated via an LLM endpoint after the rehearsal ends.

Vibe code Decktopus: FAQ
- Can you vibe code Decktopus yourself?
- Solid side project — 62/100 vibecodeable. You can build a solid personal subset featuring prompt-based deck generation, layout rendering, and basic export, but the automated brand scraper and real-time AI delivery coach will require tedious debugging.
- How long does it take to vibe code Decktopus?
- 3-4 weeks of focused building — roughly 35-50 hours of hands-on time with an AI coding agent.
- How do you build your own Decktopus?
- Scoped to personal use: Next.js with Tailwind CSS on the front, Next.js API Routes behind it, Turso (SQLite at the edge) for data. Follow the 6-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own Decktopus without being an expert?
- Use an AI coding tool (Claude Code or Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 3-4 weeks of focused building. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Decktopus instead of paying?
- About ~$22 one-time to start and $0/mo to run, versus $24.99/mo for Decktopus. Break-even: Free forever (personal build).
- What stack should you use to vibe code Decktopus?
- Next.js with Tailwind CSS; Next.js API Routes; Turso (SQLite at the edge); plus pptxgenjs for PowerPoint export, html2canvas for thumbnail rendering, Anthropic API for slide content generation.
