01 / HOW IT WORKS

What the app actually does

Laper's insight is that screenwriting and pre-production involve dozens of separate tools — Final Draft for scripts, Photoshop for storyboards, spreadsheets for breakdowns, Google Docs for notes, separate budgeting tools. A filmmaker switches between 6-8 apps daily. Laper collapses everything into one AI-powered workspace where the script generates the breakdown, the breakdown generates the storyboard, and the storyboard feeds the budget — all connected.

1

Writer opens the AI screenplay editor

Industry-standard formatting (Courier 12pt, proper sluglines, action, dialogue) happens automatically as you type. AI auto-completes scene descriptions, suggests dialogue, and maintains character voice consistency across the entire script.

2

AI generates scene breakdowns from the finished script

One click: the AI reads every scene and extracts cast required, props, wardrobe, VFX notes, locations, time of day, and estimated shoot duration. This is work that takes a production team 2-3 days — done in seconds.

3

AI creates storyboards and art direction from each scene

Describe a scene in text, AI generates a visual storyboard frame — camera angle, composition, lighting mood, color palette. Directors can iterate on framing before a single camera is set up on set.

4

The entire team collaborates in real-time

Writer, director, cinematographer, producer — all in one workspace. Comments on specific scenes, version history, locked pages for production drafts, and a shared breakdown board that updates as the script changes.

02 / INDIA POTENTIAL

Does this work as an India play

India produces over 1,800 films per year — more than any country in the world including the US. Bollywood, Tollywood, Kollywood, Mollywood, and dozens of regional industries all need pre-production tools. Almost none of them use specialised software — scripts are written in Google Docs, breakdowns in spreadsheets, storyboards on paper. An India-first AI filmmaking tool has a massive untapped market.

1,800+
Films produced in India every year — the world's largest film industry by volume. Hindi, Telugu, Tamil, Kannada, Malayalam, Bengali, Marathi — every regional industry needs pre-production tools.
Regional
An AI screenplay editor that supports Hindi, Telugu, Tamil, and other Indian language scripts — with correct formatting for bilingual screenplays (Hindi dialogue, English action lines) — is something no global tool offers and every Indian production house needs.
₹999/mo
Realistic India-priced entry tier vs Laper's $20/month — opens independent Indian filmmakers, film school students, and small production houses who can't justify global SaaS pricing but need professional tools.
YouTube
India has 800M+ YouTube users. Short film creators, web series producers, and YouTube filmmakers are a massive segment who need professional pre-production tools but can't afford full production studio workflows.
03 / THE WEEKEND BUILD

Friday to Sunday, hour by hour

Scope to AI screenplay editor + AI scene breakdown for v1. Skip storyboard generation and budgeting for the first weekend — the editor and breakdown alone are already a complete product filmmakers will pay for.

Friday
Evening · 3 hrs
7–8 PM Set up Next.js + Supabase. Build the screenplay editor using a rich text editor (TipTap or Slate.js) with custom screenplay formatting — auto-detecting sluglines (INT./EXT.), character names (ALL CAPS), dialogue indentation, and parentheticals.
8–9 PM Add AI auto-complete to the editor — integrate Gemini API so the writer can press Tab to get AI-suggested dialogue, scene descriptions, or action lines that match the tone and characters already established in the script.
9–10 PM Build the script structure panel — a sidebar showing all scenes as a collapsible outline with scene numbers, locations, and character appearances. Click any scene to jump to it in the editor.
Saturday
Full day · 7 hrs
Morning Build the AI scene breakdown generator — user clicks "Generate Breakdown" on any scene. The AI reads the scene text and extracts: cast required, props, wardrobe, VFX, location details, time of day, and estimated shoot duration.
Afternoon Build the breakdown dashboard — all scenes displayed in a grid with their extracted elements. Filter by character (show all scenes with Character A), by location, by prop. This is the production planning view.
Evening Add Hindi and bilingual script support — most Indian screenplays have Hindi dialogue with English action lines. The editor should handle Devanagari input for dialogue blocks while keeping English formatting for sluglines and action.
Sunday
5 hrs
Morning Build real-time collaboration — multiple users editing the same script using Supabase Realtime or Yjs. Writer and director both see changes live. Scene-level locking so two people don't edit the same scene simultaneously.
Afternoon Razorpay integration — Rs999/month Starter (1 project, AI auto-complete, breakdowns), Rs2,499/month Pro (unlimited projects, collaboration, export to PDF in industry format).
Evening Test with a real 10-page script — write or paste a scene, test AI auto-complete, generate breakdown, export to PDF. Record the demo showing the breakdown happening in real time.

06 / MARKETING & REVENUE

Getting paying users

How to market it

  • Post the demo reel: "I pasted a 10-page script and the AI broke down every scene — cast, props, locations, VFX, shoot duration — in 8 seconds. This takes a production team 2-3 days." Show the breakdown happening live. This is the hook.
  • Target Indian film school students and independent filmmakers on Instagram and YouTube — FTII, Whistling Woods, LV Prasad, and dozens of regional film schools produce thousands of potential users every year.
  • The Hindi screenplay reel is its own dedicated post: "Finally an AI screenplay editor that handles Hindi dialogue and English action lines in the same script — built for Indian screenwriters." This reaches Bollywood, Tollywood, and regional film communities instantly.
  • DM 20 independent Indian directors and producers on Instagram who are currently in pre-production — offer them a free month. One production house using it publicly becomes your entire marketing strategy.
  • Partner with Indian filmmaking YouTube channels (Drishyam Films, Film Companion, Cinema Beyond Entertainment) for feature reviews — the Indian filmmaking community is tight-knit and word-of-mouth drives everything.

Who pays, and why

  • Independent Indian filmmakers and directors who currently write scripts in Google Docs and do breakdowns in spreadsheets — they need professional tools at Indian pricing.
  • Indian film school students who need screenplay formatting software but cannot justify Final Draft's $250 price tag — Rs999/month is accessible.
  • Indian YouTube and web series creators who are producing 10-20 minute episodes and need lightweight pre-production tools without the overhead of full production studio software.

BUILD_PROMPT.txt
I want to build an AI-powered screenplay editor and pre-production platform for the Indian film industry, inspired by Laper (laper.ai — Rs24L/month on TrustMRR, 53% MoM growth, Cursor meets CapCut meets Figma for filmmak
ing), scoped to ship a working version in a single weekend. Core product: 1. AI screenplay editor using TipTap or Slate.js with automatic industry-standard formatting — sluglines (INT./EXT.), character names, dialogue indentation, parentheticals, transitions. Writer types naturally, formatting happens automatically. 2. AI auto-complete: press Tab anywhere in the script and Gemini API suggests the next line of dialogue, action, or scene description, maintaining consistency with established characters, tone, and plot. 3. Script structure sidebar: collapsible outline showing all scenes with numbers, locations, and character appearances. Click to jump. 4. AI scene breakdown generator: one click generates a breakdown for any scene — cast required, props, wardrobe, VFX notes, locations, time of day, estimated shoot duration. Extracted automatically from the script text. 5. Breakdown dashboard: all scenes in a filterable grid. Filter by character, location, or prop. This is the production planning view. 6. Hindi and bilingual support: the editor handles Devanagari input for dialogue blocks while keeping English formatting for sluglines and action lines — essential for Indian screenplays. 7. Real-time collaboration via Supabase Realtime or Yjs — writer and director editing simultaneously with scene-level locking. 8. PDF export in industry-standard screenplay format (Courier 12pt, correct margins, scene numbers). 9. Pricing: Rs999/month Starter (1 project, AI, breakdowns), Rs2,499/month Pro (unlimited projects, collaboration, exports). Stack: Next.js 14, TipTap or Slate.js for the editor, Supabase for auth + database + realtime, Gemini API for AI features, React-PDF or Puppeteer for PDF export, Razorpay for UPI-first billing. Deploy: Vercel. Help me step by step: 1. Set up TipTap with custom screenplay block types (slugline, action, character, dialogue, parenthetical, transition). 2. Build the auto-formatting logic — detecting when the user types INT. or EXT. and auto-applying slugline formatting. 3. Integrate Gemini for Tab-to-autocomplete with screenplay context. 4. Build the scene structure sidebar with outline navigation. 5. Build the AI breakdown generator that extracts production elements from scene text. 6. Add Devanagari input support for Hindi dialogue blocks. 7. Add real-time collaboration with Supabase Realtime. 8. Build PDF export in standard screenplay format. 9. Wire up Razorpay. India-first: Hindi/Devanagari support is mandatory. Indian screenplays mix Hindi dialogue with English action lines — this must work natively. Price at Rs999/month to undercut Final Draft ($250 one-time) and Celtx ($15/month). If I get stuck, tell me to ask @buildwithkanhaa.
