# Documents

> Read, write, store, and shuttle PDFs and office documents between your integrations, your Memories, and the AI.

Notis treats documents as first-class citizens. You can send a PDF as a voice-note attachment, ask Notis to pull a contract from your Drive, file it into your Memories, and generate a polished Word follow-up — all in the same conversation.

## Read documents

Notis understands the formats you actually use day to day:

* **PDF** — contracts, receipts, research papers, scanned forms
* **Microsoft Office** — `.docx`, `.xlsx`, `.pptx`
* **Plain text and code** — `.txt`, `.md`, `.csv`, `.json`, `.py`, `.ts`, etc.
* **Spreadsheets** — `.xlsx` and `.csv` are parsed as structured data, not just text

You can attach a file directly to your message, or paste a URL — Notis will download and read it.

**Examples**

> *"Summarize this 30-page contract and flag any clause that's unusual."*

> *"What's the total for VAT in this invoice PDF?"*

> *"Compare these two .docx versions and list every change."*

<Tip>
  Want to extract data from a photo of a receipt or business card instead of a PDF? Use [Images](/tools/images) — Vision handles image-only content.
</Tip>

### Limits

* **50 MB per file** when sent directly to the model
* **50 MB combined** across all attachments in a single turn
* For larger files, ask Notis to upload to Drive or Notion first, then reference the link

## Move documents through your integrations

Notis can upload to and download from any connected integration. The doc never has to leave the conversation — Notis fetches it, works with it, and saves it back wherever you want.

**Examples**

> *"Pull the latest contract PDF from my Drive 'Legal' folder."*

> *"Save this deck to my Notion `Resources` database with the tag 'Q2 review'."*

> *"Email this PDF to [ops@acme.com](mailto:ops@acme.com) with a one-line summary."*

> *"Add the receipt I just sent to my Expenses database in Notion."*

See [Integrations](/get-started/integrations) for the full list of connected services and how to add more.

## Save documents to your Memories

When a document should stay searchable forever — brand guidelines, account numbers, a process you reference often — save it to your Memories. Notis indexes the content so it can recall passages on demand, even months later.

**Examples**

> *"Save this brand guideline PDF to my long-term memory."*

> *"Add my 2026 tax forms to memory and remember they're stored there."*

You can also drag files into the Memories section of the portal. See [Memories](/tools/long-term-memory) for the full reference.

## Create and edit documents with skills

<Note>
  Creating and editing documents is included in the **Pro+** and **Ultra** plans — it runs on [Skills](/tools/skills) inside the cloud sandbox. On Pro, ask Notis to upgrade, or switch your free trial to Pro+ at no charge to try it. Reading documents works on every plan.
</Note>

Skills give Notis the muscle to actually produce polished documents — not just text. The right skill turns a brief into a formatted Word doc, a receipt pile into a clean spreadsheet, or a content outline into a slide deck.

| Format             | Powered by                   |
| ------------------ | ---------------------------- |
| PDF                | reportlab, pdfplumber, pypdf |
| Word (.docx)       | python-docx                  |
| Excel (.xlsx)      | openpyxl                     |
| PowerPoint (.pptx) | python-pptx                  |

**Examples**

> *"Turn this brief into a 3-page PDF proposal with our logo on the cover."*

> *"Add a 'Risks' section to the attached spec.docx without rewriting the rest."*

> *"Build an expense XLSX from these receipts grouped by category."*

> *"Generate a 5-slide pitch deck from these talking points."*

Browse the catalog at [Skills](/tools/skills) — many document skills are pre-installed, and you can create your own with a brand voice or template baked in.

## Common questions

**What file types can Notis read?**

PDF, DOCX, XLSX, PPTX, TXT, MD, CSV, JSON, and most common code formats. Image-only files (JPG, PNG) are handled through [Images](/tools/images).

**Can Notis OCR scanned PDFs?**

Yes — Notis automatically falls back to OCR when a PDF has no embedded text layer.

**Can Notis sign PDFs?**

Not directly. Notis can fill out fields and prepare a signed-ready PDF, but signing happens through your e-signature service (DocuSign, HelloSign, etc.).
