Redraft

Edit, generate, and sign PDFs — exactly how you want them.

Redraft is a document tool for people who work with PDFs at scale:

• PDF Editor — click any text or number and change it in place; add free text in the document's own font; draw or type a signature and place it anywhere.
• Bulk Generator — pick the fields that vary, map them to a spreadsheet, and generate hundreds of documents (a ZIP, or one merged PDF), named per client.
• Annex Automation — scan a billing annex once, then remove lines and recompute totals from a CSV, across pages, for any client.
• Start from text — paste a contract, letter, or agreement → get a clean, professionally-typeset, editable & signable PDF (see the Compose API below).
• Cloud templates & signatures — save a template + its setup to your account and reuse it on any device.

Architecture

Piece	Stack	Hosting
Frontend	Vite + React (MPA), Tailwind	Vercel — redraft.dev
Backend	FastAPI + PyMuPDF (stateless)	Hugging Face Space (Docker)
Auth + DB	Supabase (Postgres, RLS, Storage)	Supabase

• Stateless backend — files are processed in memory and never stored server-side.
• Auth is opt-in — the API enforces a Supabase JWT when SUPABASE_* env vars are set; without them it runs open (local dev). Per-user monthly limits are metered in the profiles table.

Run locally

# backend  →  http://localhost:8000
uvicorn api:app --app-dir backend --host 0.0.0.0 --port 8000 --reload

# frontend →  http://localhost:5173   (app at /app.html)
npm --prefix frontend install
npm --prefix frontend run dev

The frontend reads VITE_API_BASE (defaults to http://localhost:8000) and the VITE_SUPABASE_* keys from frontend/.env.local.

Branches

• main — what's deployed to redraft.dev.
• redraft-dev — where work happens; open a PR to main when it's solid.

Compose API — text → clean editable PDF

Turn plain text into a professionally-typeset, editable & signable PDF in one HTTP call. No template, no design work. Built for contracts, letters, and agreements.

Status: the endpoint currently requires a signed-in Redraft session. A public (no-login) version + an embeddable button is the planned next step — see "Making it a public button" below.

Endpoint

POST https://dahuum-radraft.hf.space/compose
Content-Type: multipart/form-data

Field	Required	Description
text	✅	The document body. Blank lines separate paragraphs.
title	optional	Document title (centered, bold, over a rule).
meta	optional	Overrides the reference line. Defaults to Référence : ___ · Date : <today>.

Automatic formatting: blank lines → justified paragraphs; a short line that is Article … / Section … / Clause … / numbered / ALL-CAPS → a bold heading; a signature block is appended; long documents paginate onto multiple A4 pages.

Returns: an application/pdf file — Classic Legal styling, ready to edit and sign.

Examples

curl

curl -X POST https://dahuum-radraft.hf.space/compose \
  -F "title=CONTRAT DE PRESTATION DE SERVICE" \
  -F $'text=Entre les soussignés :\n\nLa société ACME SARL, ci-après « le Prestataire ».\n\nArticle 1 — Objet\n\nRéalisation d\'une plateforme de facturation.\n\nArticle 2 — Rémunération\n\n120 000,00 MAD hors taxes.' \
  -o contract.pdf

JavaScript — a button on any website

<button id="make-contract">Create contract</button>
<script>
document.getElementById("make-contract").onclick = async () => {
  const fd = new FormData();
  fd.append("title", "Service Agreement");
  fd.append("text", document.getElementById("contract-text").value);
  const res = await fetch("https://dahuum-radraft.hf.space/compose", { method: "POST", body: fd });
  const blob = await res.blob();
  window.open(URL.createObjectURL(blob)); // preview / download the PDF
};
</script>

Python

import requests
r = requests.post(
    "https://dahuum-radraft.hf.space/compose",
    data={"title": "Service Agreement", "text": open("contract.txt").read()},
)
open("contract.pdf", "wb").write(r.content)

Making it a public button

To let anyone use this with no account:

1. Drop the login requirement on /compose (it's a cheap generate call).
2. Rate-limit by IP (e.g. 20 documents/hour) to prevent abuse.
3. Ship a hosted page redraft.dev/new — paste title + text → Create → the PDF.
4. Provide the embed snippet above for integrators.

Later: open the composed PDF in a guest editor so recipients can sign without an account — the full "generate → edit → sign, embedded anywhere" flow.

Legacy billing scripts

The repository also contains the original Streamlit invoice generator (main.py, generate_bills.py, reconstruct.py, invoices_db.csv). These are kept for reference and are independent of the backend/ + frontend/ app.
