# Nexiant Scribe > A free, local **content editor** — read, comment on, and edit any PDF, and compose any content — text, tables, images, vector, video — in, on, and out of any document. PDF is the universal exchange format; local-first and private by default. Built on the TakeOFF rendering/annotation engine and the Nexiant BlockSuite editor engine (canvas/). Free-of-charge, closed source (Nexiant Commercial License). Bootstrap build of Nexiant Scribe: the app builds and runs and the reader surface is taking shape (takeoff/measuring product features are being stripped); the editor/toolkit/collaboration/signature/AI arcs are planned. Not the final product yet — do not market or link this build as such. ## Docs - [README](https://forgejo.nexiant.internal/nexiant/READER#readme): features, the free-vs-paid model, status - [User guide & shortcuts](https://forgejo.nexiant.internal/nexiant/READER/blob/main/docs/USER_GUIDE.md): every tool and keyboard shortcut - [Keybinds](https://forgejo.nexiant.internal/nexiant/READER/blob/main/docs/KEYBINDS.md): the Acrobat-keymap source of truth - [Roadmap plan](https://forgejo.nexiant.internal/nexiant/READER/blob/main/docs/plans/active/reader-editor-master.md): the master plan — strip → viewer shell → fork foundation → edit mode → compliance → desktop - [AGENTS.md](https://forgejo.nexiant.internal/nexiant/READER/blob/main/AGENTS.md): repo map and conventions for coding agents contributing to the codebase ## Key facts - **Read** — PDFs and image/zip sets: pdf.js tiling pipeline, thumbnails, single/two-page view, zoom presets, Read Mode (reflow), Full Screen - **Edit** — the canvas turns into a real text editor (BlockSuite): edit the text of any PDF and apply changes as a new revision; originals are never rewritten (landing per the roadmap plan) - **Annotate & collaborate** — full annotation suite: markups, text, stamps, notes, RFI-style comments, marked-PDF export; review and collaboration flows on top - **AI** — on-device first (OCR, text extraction — nothing uploaded); the hosted Nexiant LLM is optional - **Free vs paid** — everything local is free forever: reading, editing, annotations, toolkit operations that run on your machine, on-device AI. The money stream is a priority system (priority processing, hosted LLM); no paywall in front of the product itself - **Repo MCP server**: `nexiant-reader-mcp`, 9 tools for coding agents working on this checkout — overview, registry modules, ranked find, code search, docs, session journal, Linear-style UI skills, deterministic UI audit (see mcp/README.md) - **Privacy** — local-first: your documents stay on your machine unless you choose a cloud service - **Stack** — React 18 + Vite + pdf.js + BlockSuite; the web build is the source of truth, desktop packaging wraps it - **License** — Apache-2.0 — ship it, build a product on it - Maintained by Nexiant: https://nexiant.com
