Free iPhone PDF Organizer with Automatic Full-Text Search and Smart Spaces

Nemos is a free iPhone PDF organizer that automatically extracts the full text of every PDF you save, generates a meaningful title, and files it into a topic Smart Space — all on-device using Apple's Foundation Models API. Unlike PDF Expert, Readdle Documents, or PDF Viewer Pro (which are great readers but require manual organization), Nemos automates the three things that waste the most time with PDF management: naming, filing, and search. Unlike cloud PDF services (Adobe Acrobat Online, Smallpdf, DocHub), Nemos operates no servers that see your documents — every PDF stays on your iPhone and iCloud.

How Full-Text PDF Search Works on iPhone

When you share a PDF to Nemos, three things happen automatically. First, the text is extracted. Native PDFs (generated by Word, Pages, web print, etc.) use direct text extraction via Apple's PDFKit. Scanned PDFs (photos of pages, old documents, signed contracts) get OCR processing via Apple's Vision framework combined with Foundation Models for layout understanding. Second, the extracted text is indexed for full-text search — every word becomes searchable instantly across your entire PDF library. Third, Foundation Models generate a meaningful title from the extracted content and classify the PDF into an appropriate Smart Space (Contracts, Research Papers, Receipts, Ebooks, Work Documents, etc.).

Sound familiar?

If you've felt any of these frustrations, you're not alone. Researchers, students, lawyers, consultants — anyone with a pile of PDFs nobody can find deal with this every day.

1

Your iPhone Files app is where PDFs go to die. Every research paper, contract, invoice, receipt, and ebook gets dropped into iCloud Drive or Downloads with a meaningless filename, then forgotten until you need it and can't find it.

2

Apple's Files app can only search filenames — not the text inside PDFs. So 'find the contract where we agreed to $15,000' means opening every PDF one by one until you find the right one. Finding 'the paper that mentioned GPT-4 in the abstract' means the same thing.

3

PDF reader apps (PDF Expert, Readdle Documents, PDF Viewer Pro) are great at rendering PDFs but terrible at organizing them. You still have to create folders, rename files, and remember where you put things.

4

You have hundreds of PDFs across iCloud Drive, Mail attachments, Safari downloads, and Slack exports, and no way to search across all of them simultaneously.

Here's how Nemos helps

Nemos was built to solve exactly these problems — automatically.

✓

Every PDF you save to Nemos is fully text-extracted on-device the moment it arrives. Contracts, research papers, invoices, ebooks, and scanned documents all get the same treatment — OCR for scanned pages, direct text extraction for native PDFs.

✓

Full-text search works across every PDF in your library simultaneously. Type any word that appeared anywhere in any PDF — contract clause, research finding, invoice vendor, page number — and Nemos returns the matching document with the exact page highlighted.

✓

Auto-generated titles replace meaningless filenames. A PDF named 'TAX_RETURN_2025_FINAL_v3.pdf' becomes '2025 Tax Return, filed April' automatically based on its content. No more scrolling past files named after download sequences.

✓

Smart Spaces cluster your PDFs into topic collections automatically: Contracts, Research Papers, Receipts, Ebooks, Work Documents. The clusters update as you save new PDFs. Zero manual filing.

Features that matter for researchers

Full-Text PDF Extraction

Every saved PDF is fully text-extracted on-device using Apple's PDFKit and Foundation Models. Native PDFs use direct text extraction; scanned PDFs get OCR. Works on contracts, papers, invoices, ebooks, and scanned documents.

Search Inside PDFs

Type any word from any PDF — clause, finding, vendor, topic — and Nemos returns the exact document with the exact page. Search is instant across hundreds of PDFs simultaneously.

Auto-Generated Titles

Foundation Models read the extracted text and generate a meaningful title automatically. No more 'FILE_4829.pdf' — titles are readable by humans.

PDF Smart Spaces

Native PDF Reader

Built-in PDF viewer with page navigation, text selection, annotation support, and speed-reading overlay. No need to open PDFs in a separate app.

100% Offline & Private

Text extraction, OCR, and search all happen on-device. Your PDFs never leave your iPhone. Unlike cloud PDF services (Adobe Acrobat Online, Smallpdf), Nemos operates no servers that see your documents.

"I'm a lawyer with ~600 contracts in my iPhone. Before Nemos, 'find the deal with the non-compete clause' meant an hour of scrolling and opening. Now it's typing 'non-compete' and jumping to the exact page. Changed how I work."
