Fillable vs PlatoForms

Fillable is a web and API service for turning PDFs into guided client workflows. It detects fields, accepts document uploads, supports signatures, and creates shareable completion links that clients can use without an account or app. Browser tools can fill, create, sign, merge, split, compress, convert, and OCR PDFs. Guided packs collect completed forms and requested documents; the free plan includes one active pack, all library templates and official forms, and a test API key. Teams can import existing PDFs, apply field validation and conditional logic, and export PDF or JSON. The REST API parses PDF fields and text into JSON and fills existing form fields. Each key allows 100 requests per calendar day, counting authenticated calls that succeed or return errors. It does not create PDFs from HTML, convert file formats, or add fields to flat PDFs. Core tools run in the browser; server-side conversions upload files and delete them afterward. Paid monthly plans start at $9/mo.

PlatoForms converts existing PDFs into online forms and returns completed PDFs in the original format after submission. Its AI can detect fields in PDFs and generate document sections, fields, and signature blocks from a description. Forms can use a classic layout or ask one question at a time in a conversational format. Workflow tools support multi-step approvals, branching, parallel paths, and routing one PDF among several people. PlatoForms offers more than 2,000 form and document templates, integrations with file storage, payment, and automation services, and REST APIs for submissions, prefilled fields, completed-PDF webhooks, invitations, and form management. Forms can collect Stripe, PayPal, or Square payments; PlatoForms says it adds no transaction fees. The listed plans are Free at free, Bronze at $10 a month, Silver at $30 a month, and Gold at $80 a month, with paid-plan billing listed annually.
