JustFill.app logo JustFill.app

Fill any PDF — even scans and flattened forms Adobe can't open. AI finds every field, so you can type, fill and reuse it online. Mail merge from Excel or CSV gives you one filled PDF per row.

JustFill fills PDF forms that other tools refuse to open — scans, photos of paper documents, and flattened forms that contain no form fields at all.

How it works. Upload a PDF and an AI detector finds the fields on the page, including checkboxes and comb boxes on scanned documents. Type your answers, drag any field into place in the editor, and download a clean PDF with your text placed on the original — formatting, logos and layout untouched.

Reusable templates. Save a layout once and reuse it on the same form forever, without detecting anything again.

Mail merge for PDFs. Point JustFill at an Excel or CSV file and get one filled PDF per row, delivered as a ZIP — useful for onboarding packets, invoices, and any form you send out repeatedly with different data.

Make a PDF fillable. Turn a flat or scanned document into a real fillable PDF with proper form fields that anyone can complete in a normal PDF reader.

Voice dictation for long forms, in several languages.

For developers and AI agents. An MCP server lets Claude and other agents fill PDFs directly, and an official n8n node brings PDF filling into automation workflows.

Filling, editing and preview are free. Paid plans cover clean, watermark-free output at volume.

JustFill.app features and specs

  • Automated Form Filling
    JustFill.app automates the process of filling out repetitive forms, saving users significant time and reducing manual data entry effort.
  • User-Friendly Interface
    The platform is designed with simplicity in mind, making it accessible for users who may not be highly technical to set up and use form-filling automation.
  • Browser Extension Convenience
    Being available as a browser extension allows users to fill forms directly within their normal browsing workflow without switching between multiple applications.
  • Time Savings
    By automating data entry into web forms, users can complete tasks like job applications, registrations, or surveys much faster than manual entry.
  • Reduces Data Entry Errors
    Automated filling can help minimize typos and inconsistencies that often occur with manual form completion.

startbase.dev features and specs

  • Faster project setup
    Startbase.dev appears designed to help developers and founders quickly scaffold new projects with pre-built templates and boilerplate code, saving significant time compared to starting from scratch.
  • Focus on startups/MVPs
    The platform seems tailored toward entrepreneurs and indie developers who want to launch minimum viable products quickly, which can be valuable for validating ideas without heavy upfront investment.
  • Modern tech stack
    Such starter kits typically integrate current, popular frameworks and tools (e.g., Next.js, Tailwind, authentication, payments), reducing the need to research and configure these integrations manually.
  • Reduced boilerplate maintenance
    By using a pre-built base, developers can avoid reinventing common features like user authentication, billing, and dashboards, letting them focus on unique business logic instead.
  • Potential cost savings
    Compared to hiring a development team to build core infrastructure from scratch, using a starter template service can be more affordable for solo founders or small teams with limited budgets.

Possible disadvantages of startbase.dev

  • Limited customization flexibility
    Pre-built starter kits and boilerplates often come with opinionated architecture and design choices that can be difficult or time-consuming to modify for highly specific or unconventional use cases.
  • Vendor/template lock-in risk
    Relying on a specific boilerplate structure may create dependencies on certain libraries, patterns, or update cycles that could complicate long-term maintenance if the base template becomes outdated.
  • Learning curve for the specific stack
    If the chosen tech stack differs from what a developer is familiar with, there may still be a learning curve to understand and effectively customize the starter codebase.
  • Uncertain long-term support
    As a smaller or newer platform, there may be concerns about the longevity of updates, community support, and documentation compared to more established open-source alternatives.
  • Pricing transparency concerns
    Depending on the pricing model, users may find costs less transparent or harder to justify compared to free, open-source boilerplates available elsewhere in the developer community.
