DocSpring is an API for filling, generating and signing documents. Developers build it into their products to turn data into finished PDFs and Word files. Start from the document you already have, or design one: - PDF forms: upload any PDF, fillable or flat. AI finds the fields, names them, picks their types and adds conditional logic. - Word templates: type tags into a Word document (.docx) or an OpenDocument text file (.odt), with conditions and loops for table rows. Get back a Word file, an OpenDocument file or a PDF. - Page Designer: build a PDF template from a blank page with text, tables, images, charts, barcodes and form fields. Your AI agent can write the layout too. - HTML templates: HTML, CSS and Liquid, for documents that grow with their data. Send JSON from your app, one document at a time or 50 in a request, and get back the finished file. Send it for e-signature with one or more signers and a full audit trail, or let people fill it in through a hosted or embedded web form. Your customers can set up their own templates in DocSpring's editor, embedded in your app without our branding. Use the REST API, SDKs in 10 languages, webhooks, or the MCP server with Claude, ChatGPT, Cursor and VS Code. Connect Zapier, Make, n8n, AWS S3, Google Drive, Dropbox, Box and Slack. DocSpring is SOC 2 Type II audited and HIPAA compliant, with a BAA on every paid plan, and keeps your data in the US or the EU. The Developer plan is free with no time limit: 200 credits every month, enough for 10 filled PDF forms or Word documents, and unlimited test PDFs. No credit card needed.
