Everything you'd juggle a PDF editor and an e-signature service for, in one elegant workspace, with AI that handles the tedious parts. Everyday editing runs right in your browser, so your files stay yours.
Twenty-three tools live in one calm interface, from everyday PDF edits to AI splitting, signature requests, and tracked distribution.
Every PDF tool you'd expect lives here too. But these are the reasons people stay.
Drop fields onto any PDF, add signers in order, and send. Recipients get a beautiful, guided signing page — no account, no app. You watch every view and signature land, with a full audit trail on every sealed copy.
NyxPrism reads the stack, finds where each document begins, and names every file like a meticulous assistant would. Ask any PDF a question and get answers cited to the page, or let AI turn a flat form into a fillable one.
The Professional tier ships with NyxPrism UI - a full TUI built on Textual. Every operation is a guided form. No command memorisation required.
Live backgrounds you can play with: shatter a floating prism, pop a bubble, or use your own photo. Pick a theme, accent color and button glow.
No configuration files. No setup wizards. Drop a PDF in, get organized files out.
Feed NyxPrism any multi-document PDF - a day's worth of scanned mail, a stack of contracts, or an invoice run. One file, any size.
The heuristic engine (or GPT-4o-mini with your API key) reads each page, detects where one document ends and the next begins, and generates a descriptive file name for each.
The output folder fills with individually named PDFs - NDA_Acme_Corp.pdf, Invoice_0042.pdf, Q1_Report.pdf. Ready to file, email, or archive.
One install handles everything. No juggling multiple tools or online converters.

Merge, split, rotate, reorder, number, annotate, and rebuild pages without sending the file to another service.
Find document boundaries inside large batch scans, then create clean, descriptively named files in one pass.
Place recipient fields, send sequential requests, track completion, and retain a tamper-evident audit record.
Share expiring document links with individuals or recipient batches and monitor opened or failed delivery states.
Recover text from scans, create searchable PDFs, and move cleanly between PDF, image, and text formats.
Encrypt sensitive documents, apply watermarks, flatten forms, and permanently remove confidential regions.
Concatenate PDFs with bookmarks, or interleave odd/even scans into a perfect double-sided document.
Shrink bloated PDFs using FlateDecode stream compression and configurable JPEG image re-encoding.
Extract text from image-only scans. AI analysis automatically triggers OCR on blank pages so nothing is missed.
Render every page as PNG/JPEG, or assemble a stack of images back into a clean PDF with a single command.
Text watermarks with configurable opacity and rotation, applied uniformly across every page in a single pass.
Password-encrypt sensitive documents with user/owner passwords, or remove protection from existing PDFs.
From solo developers to enterprise automation pipelines.
Extract key dates and parties from contracts automatically. Classify incoming documents and route them to the right folder instantly.
Pull amounts, invoice numbers, and vendor names from invoices as JSON. Automate the data entry nobody wants to do.
Turn a pile of unnamed scans into a perfectly organized archive with a single ai-rename command.
Summarise dense papers, extract citations and dates, and split multi-paper batch scans from the copier.
Organize bulk scan exports and apply watermarks or passwords. Before processing protected health information, verify your organization's required agreements and safeguards.
Drop NyxPrism into any Python pipeline or shell script. Scriptable, composable, and library-friendly with a clean Python API.

The essentials before you get started.
The web dashboard's cloud AI is available only when NyxPrism has explicitly enabled its Anthropic integration; otherwise those features are unavailable. When enabled, relevant document text is sent to Anthropic for processing. Do not submit sensitive or regulated information unless you are authorized to do so. The CLI tool also has a built-in heuristic engine that runs with no API key and no cost.
Everyday editing tools run in your browser. Cloud AI, signature requests, and document distribution send only the content needed for the workflow you choose. See our Privacy Policy for full details.
Edit, organize, convert, OCR, redact, protect, sign, and distribute PDFs from one visual workspace. AI tools are available when you need deeper document analysis.
Only for the ocr command or AI analysis of image-only scanned PDFs. Install separately (sudo apt install tesseract-ocr on Linux, brew install tesseract on macOS). For PDFs with a selectable text layer, OCR is not needed.
Yes. Every command has a corresponding Python function. Import from nyxprism.core.* and nyxprism.ai.* to integrate directly into your own scripts and applications.
Automate PDF workflows from your own code with the NyxPrism REST API - authenticated by the keys you generate in the dashboard.
Generate an API key from your dashboard, then call the same backend that powers the web app - with full subscription gating and per-key tracking.
