24 alternatives to Filling PDF forms with AI using client-side tool calling
Hey HN! I built SimplePDF Copilot: an AI assistant that can interact with the PDF editor. It fills fields, answers questions, focuses on a specific field, adds fields, deletes pages, and so on. It's built on top of SimplePDF that I started 7 years ago, pioneering privacy-respecting client-side pdf editing, now used monthly by 200k+ people. As for the privacy model: the PDF itself never leaves the browser. Parsing, rendering, and field detection all run client-side. The text the model needs (and your messages) goes to whatever LLM you point at. By default that's our demo proxy (DeepSeek V4…
SimplePDF Copilot is an AI assistant that interacts with PDF documents to fill form fields, answer questions, add or delete fields, and perform other editing tasks.

BreezePDF lets you edit, sign, merge, compress, redact, OCR, fill forms, extract tables, and use 30+ more PDF tools — all in the browser, no sign-up. Files never leave your computer. I built it because when people search Google for common PDF tasks, many of the tools they find upload documents to a server. I wanted an option that keeps files local instead. I posted an earlier version on HN last spring: https://news.ycombinator.com/item?id=43880962 At the time it only supported a small set of features. Over the last 10 months I rebuilt large parts of it and expanded it to…

Hi HN! I've been working on SimplePDF to solve a problem I encounter weekly: filling out non-editable PDFs [1] --- # About SimplePDF - The documents you load, edit, fill never see the light of my server, everything is processed locally – no remote uploading anything. This includes the PDF generation. - There are no analytics / third party tracking your every move (I do collect usage data, but it's fully anonymous and processed and stored on my server): therefore no annoying cookie banner. You can read more on the Privacy Policy [2] - If someone before you has filled the same document,…

I created this tool to make it quick and easy to sign PDF contracts, without having to deal with installing additional software and without worrying that my PDFs will get uploaded to a third party. It supports the bare minimum for my most common usecases. It is not intended to be a full-featured PDF editor. Features include filling PDF forms, inserting images and text, and rotating PDFs. Check it out by either picking a PDF of your own - https://photown.github.io/private-pdf/, or with a preloaded sample PDF -…

Hi HN, I'm the creator of LocalPDF (https://localpdf.online). The thing I'm sharing here is Studio: https://localpdf.online/app/studio Most PDF apps are built around isolated tools — merge, split, rotate, delete pages, edit text, and so on. That works fine for one-off tasks, but a lot of real PDF work isn't one-off. Usually it's more like: open a few files, compare them, pull pages from one into another, remove junk, reorder things, make a couple of edits, then export the result. That workflow always felt awkward to me in traditional PDF editors because you keep…
