Best Free AI PDF Editor for Android & iOS: Docly Tested

I’ve been testing free PDF tools on mobile for a while, mostly because I got tired of paying for a desktop subscription just to extract a few pages from a contract. When I stumbled onto Docly, an AI-powered PDF editor for Android and iOS, I figured it was worth a real look – especially since the free tier doesn’t immediately lock you behind a paywall. After a couple of weeks of using it on an Android phone and an iPad, here’s what I found, organized as a straightforward checklist. If you’re searching for an ai pdf editor for android ios free, these are the points that actually matter.

What an AI PDF Editor on Mobile Should Do Well

• Summarize long documents without losing key points. I threw a 40-page annual report at Docly and asked for a summary. It returned a readable bulleted list that actually matched the structure of the report. Not perfect – it missed a footnote about revenue adjustments – but for a first pass, it was faster than flipping through forty pages. This is where the ai pdf summarizer free angle really works: you can get the gist without reading every line. That said, the summary length isn’t customizable in the free version, so you get whatever the model decides is important.
• Extract text and copy it cleanly. I tested it on a scanned PDF of an old magazine article. Docly handled the OCR fairly well – no garbled letters, and I could copy text into a note without reformatting. One tradeoff: it struggled with multi-column layouts. Text from the second column appeared at the bottom of the output, which meant some manual rearranging. For single-column documents, it’s fine.
• Edit pages without a subscription. The free version lets you annotate, highlight, and even delete or reorder pages. I removed three blank pages from a meeting agenda – that worked instantly. But merging PDFs? That’s a premium feature. So if your workflow requires combining multiple files, the free tier won’t cut it. I found that limitation slightly frustrating, but for basic page-level editing, it’s serviceable.
• Work offline for the basic editing parts. Docly lets you open and annotate PDFs without an internet connection. The AI summarization requires a connection, which makes sense. I tested the offline editing in airplane mode – highlights and drawings stuck, and changes saved locally. That’s a solid plus for commuting or traveling.
• Scan files with the phone camera. The scan-to-PDF function is adequate, not great. It auto-crops and adjusts contrast, but on my Galaxy S23, the edge detection sometimes cut off the margin of a book page. I had to retake the photo. Useful in a pinch, but not a replacement for a dedicated scanner app.

The Real Tradeoffs You’ll Feel

Docly is genuinely useful for quick edits and summaries, but it’s not a full desktop replacement. The free tier shows ads – not intrusive pop-ups, but a banner at the bottom. The bigger issue is export limitations: you can’t save a summary as a separate file unless you upgrade. You can copy it out, but that’s one extra step. Also, the text extraction on complex PDFs (think dense tables with merged cells) produced some jumbled output. I wouldn’t rely on it for data-heavy spreadsheets.

I also noticed that the app occasionally takes a few seconds to load an AI summary, even on decent Wi-Fi. Not a dealbreaker, but it’s not instant.

Is This the Best Free AI PDF Editor?

I’ve tried three or four other free mobile PDF tools this year. Docly sits near the top for two reasons: the AI summary actually works, and the editing basics aren’t hidden behind a paywall. Is it the best free ai pdf editor I’ve used? It’s close, but I’d still keep an eye on the 2026 updates – PDF tools change fast, and some competitors may eventually offer unlimited page edits for free. If you primarily need to read, summarize, and lightly annotate PDFs on your phone, Docly is a solid pick right now.

If you’re looking for an ai pdf editor for android ios free that doesn’t waste your time with fake AI features, give it a download. Just go in knowing that the scanning is okay, the extraction can get messy on tricky layouts, and you’ll need to copy-paste summaries out of the app. For a zero-cost tool, that’s a reasonable tradeoff.
