How it works

Three steps from instruction to finished PDF

LetterKraft is not a generic chatbot. It is trained on your own writing so every letter sounds like you and fits the conventions of formal Indian correspondence.

  1. 01

    Add sample letters

    Upload photos, PDFs, or paste text of letters you’ve written before. LetterKraft extracts the text via on-device or cloud OCR.

  2. 02

    AI learns your style

    Create a Style Profile from your samples. LetterKraft captures your tone, structure, phrasing, and salutations.

  3. 03

    Generate, refine, export

    Give a short instruction (type or dictate). Get a full letter. Refine it inline, attach a letterhead and signature, and export a clean PDF.

Features

Built for formal letter writing, end to end

From style learning to export, every step is tuned for official communication in government, corporate, and academic settings.

Style Profiles

Train AI on your unique writing style from sample letters. Maintain distinct profiles for different roles, offices, or types of correspondence.
