Shablonix

The kit operators use,
and the call engineering keeps.

Atoms, Format utilities, and starter templates for invoices, letters, and email. Product operators drag the layout and bind the data. Builders send a template ID and JSON. Host products can keep send and drop only the letter editor in an iframe.

Atoms, Format, Inspect.

The left rail is Atoms — predefined components, not a blank code editor. Format inserts currency, dates, and names at the caret. Sections are saved pieces of the invoice, letter, or email. Inspect is the selected block.

Shablonix visual editor: Atoms and Format on the left, A4 invoice canvas, Inspect on the right.
  1. Atoms Text, tables, images, repeaters. Drag onto the page.
  2. Format Currency, dates, names. Insert at the caret.
  3. Page True-size canvas. What you arrange is what generate renders.
  4. Inspect The selected atom: type, color, spacing.
  • Atoms Text, tables, images, repeaters, and links. Drag onto the page — nothing here is template code.
  • Format Currency, dates, names, and calendar helpers. Insert at the caret as Handlebars, not a Utils menu.
  • Sections Reusable pieces of the letter or document. Save from the canvas; drop them on the next template.
  • Inspect Select an atom and tune type, color, and spacing without leaving the page.

Generate is one POST.

After the layout is approved, nothing in the call changes when someone moves a logo. That work stays in the editor.

A letter editor inside your product.

An iframe plugin, not a port of the full studio. Hosts keep subject, proof, and send. Compile returns inbox HTML. The secret API key stays on your server.

Production is keys, jobs, and usage.

API keys, generate modes, batch on paid plans, and a usage counter. Email compiles are metered separately from PDFs.

  • API keys Bearer tokens from the dashboard. Secret keys never belong in frontend JavaScript.
  • Sync or async generate Stream a PDF back, or take a job to poll. Completion webhooks are on Pro and Business.
  • Zapier and Make Private apps map template fields from Sheets, Stripe, or a CRM, generate a PDF, and fire when the job completes — without overwriting your account webhook.
  • Batch Up to 100 PDFs in one call. Same template ID and JSON shape as a single generate.
  • Usage Dashboard counts against the monthly allowance on the plan. Email compiles are metered separately.
  • DOCX and HTML PDF is the default. DOCX and HTML exist for handoff and web-specific templates.
  • Snapshots Autosave plus up to 10 restore points before a layout change you might regret.
