AttachKit vs. AskYourPDF — an editor that never uploads vs. a cloud chat that stores your files

AskYourPDF: A cloud "chat with your PDF" assistant — upload documents to ask questions, summarize, and compare, with an AI form-filler, mobile apps, a ChatGPT plugin, and an API.

AskYourPDF is a capable cloud document assistant: upload PDFs and it answers questions, summarizes long reports, compares documents, and returns cited answers, with native iOS and Android apps, a ChatGPT plugin, a Zotero plugin, a Chrome extension, and an API. It even adds an AI form-filler that can populate a form from another document. The trade-off is architectural: your files are uploaded to and stored in AskYourPDF's cloud — per its own help center, free-plan documents are kept for up to 90 days before removal — and its privacy policy names Anthropic and OpenAI as AI sub-processors. AttachKit does the everyday PDF work — fill, sign, redact, convert, reorganize, edit — entirely in your browser: the file never leaves the tab (provable in DevTools → Network), and the AI only ever sees extracted text, never the document.

Why pick AttachKit for these cases

  • Your file never leaves the browser; AskYourPDF uploads and stores it (up to 90 days on the free plan). Only extracted text ever reaches the model.
  • An agent that edits the PDF — fill, redact, sign, reorganize — with a reviewable plan you approve, not just chat plus a form-filler.
  • Verifiable, content-bound e-signatures anyone can check on any device — AskYourPDF doesn't offer a signing-and-verification suite.
  • Optional Local AI mode (your own Ollama) keeps even the extracted text on your machine — the agent's planning step stays cloud-only.
  • No account or upload to get started: open a tool and go, with unlimited fill/redact/OCR on the free tier.

Side-by-side

A marks the side with the genuine advantage on that row — honestly, including the few where AskYourPDF wins.

Where your file goes
AskYourPDFUploaded to and stored in AskYourPDF's cloud (its own help center states free-plan documents are kept up to 90 days before removal; you can delete files manually). Its privacy policy names Anthropic and OpenAI as AI sub-processors.
AttachKitNowhere — the PDF stays in your browser, verifiable in DevTools → Network. Only extracted text is sent to the AI, never the file, and there's nothing stored on a server to retain or delete.
What the AI does
AskYourPDFChat, Q&A, summaries, document comparison, cited answers, and AI writing tools over your uploaded files — plus an AI form-filler that fills a form from another document.
AttachKitAn agent that ACTS on the open document — proposes fill / replace-text / delete / reorder / extract / stamp / watermark / number edits you approve before anything changes — and answers questions about it with page cites.
Editing the PDF
AskYourPDFMostly read-only, with one real exception: an AI Form Filler for fillable and non-fillable forms. There's no page-level redaction, reorder/split/merge, or a full signing suite — it's chat plus form-fill, not a general editor.
AttachKitA full browser toolkit — fill, sign (PAdES-aligned, verifiable), redact with PII detection, reorder/extract pages, convert, OCR, watermark — driven by the agent or by hand.
Multi-document research chat
AskYourPDFA genuine strength — a persistent Knowledge Base lets you upload many documents and query across them conversationally, with OCR and very large page limits handled server-side.
AttachKitAttachKit's agent works on the document in front of you and isn't a multi-document research library. For cross-document Q&A over a big corpus, AskYourPDF is the better fit.
Mobile apps & integrations
AskYourPDFNative iOS and Android apps, an official ChatGPT plugin, a Zotero plugin for researchers, a Chrome extension, and a developer API — broad ecosystem reach.
AttachKitFully browser-based on any OS (including phones), but no native mobile apps and no ChatGPT plugin; the Max tier offers an API and an embeddable verifier.
Price
AskYourPDFFree plan ($0) with tight daily/upload limits; Premium about $11.99/mo and Pro about $14.99/mo (billed yearly; month-to-month runs higher), Enterprise custom. Some premium models are credit-gated even on paid tiers. Prices change — check their pricing page.
AttachKitFree: unlimited fill/redact/OCR + 10 AI actions/mo (edited-PDF exports capped on Free; unlimited on paid). Pro $12/mo (or $120/yr — $10/mo) with 200 AI actions/mo; Max $19/mo adds 500.
Local-only AI option
AskYourPDFCloud-based — your uploaded document is processed on AskYourPDF's servers (via Anthropic/OpenAI) to generate answers.
AttachKitOptional Local AI mode runs the AI features (auto-fill, PII detection, clause review, single-doc Q&A) on your own Ollama, so no third-party AI sees even the extracted text. The agent's planning step is cloud-only and isn't covered by Local AI mode.
No install, in-browser
AskYourPDFWeb app plus mobile apps and browser extensions — convenient, but the document is uploaded to use it.
AttachKitRuns in any modern browser with nothing to install; the difference is the file stays on your device.

Switching questions, answered

Does AskYourPDF keep my uploaded documents?
Yes — AskYourPDF is a cloud tool: your files are uploaded and stored on its servers, and per its own help center free-plan documents are retained for up to 90 days before removal (you can also delete them yourself). Its privacy policy names Anthropic and OpenAI as AI sub-processors. AttachKit never uploads the file — everything runs in your browser (confirm it in DevTools → Network) and only extracted text reaches the model. Local AI mode keeps even that on your own machine for the AI features; the agent's planning step is the cloud-only exception.
AskYourPDF can fill forms with AI — can AttachKit?
Yes. AskYourPDF's AI Form Filler is a real feature, and AttachKit matches it: save your details once and its AI maps them onto a form's fields — with the PDF staying on-device (only the field names and your saved profile go to the model, never the file). AttachKit also goes further into editing: redaction, signing, and page reorganization that AskYourPDF's chat-first product doesn't cover.
Is AskYourPDF cheaper than AttachKit?
They're close. AskYourPDF's free plan is tightly limited, and its Premium (~$11.99/mo) and Pro (~$14.99/mo) are billed yearly, with some premium models credit-gated even on paid tiers (prices change — check their page). AttachKit's free tier is genuinely useful (unlimited fill/redact/OCR + 10 AI actions/mo), and Pro is a flat $12/mo (or $120/yr) with 200 AI actions/mo included. The bigger difference isn't price — it's that AttachKit never uploads your file.
Should I use AskYourPDF or AttachKit?
For chatting across a library of documents on desktop and mobile, AskYourPDF is built for that. For editing a PDF — filling, redacting, signing, reorganizing — without the file leaving your browser, AttachKit is the tool. If your documents are sensitive enough that you'd rather they never be uploaded or stored at all, that's the case AttachKit is designed for.
