GenOffice – GenSpark's AI native office suite

GenSpark released GenOffice 0.5.1, an AI-native office suite for macOS and Windows that includes word processor, spreadsheet, presentations, and PDF apps built on a shared engine layer with AI editing as a first-class workflow. The suite routes model calls through Genspark's service, requiring no local API keys, and features byte-preserving docx editing, a Rust-based xlsx engine, and an in-house pptx engine.

An AI-native office suite for macOS and Windows: word processor, spreadsheet, presentations, and PDF — five Electron apps sharing one engine layer, built around AI editing as a first-class workflow rather than a bolted-on chat box.

Byte-preserving round trip: only dirty paragraphs are regenerated paragraph patch , everything else in the original file is kept byte-for-byte, so opening and saving never breaks layout in Word. Paginated view whose line metrics reproduce the original document's layout, tracked changes, comments, styles, equations, ink. | apps/sheets | GenOffice Sheets | .xlsx spreadsheet. UI built on the open-source | apps/slides | GenOffice Slides | .pptx presentations. In-house pptx parse/render/edit engine with masters, charts, cropping, ink, and text shaping HarfBuzz metrics . | apps/pdf | GenOffice PDF | PDF viewer/editor on pdf.js + pdf-lib: annotations, forms, outlines, stamps, signatures, page operations, print. | apps/shell | GenOffice | The suite shell: home screen, tabbed hosting of the four editors, auto-update. | Every app embeds the same AI panel: block-granular AI editing with version snapshots and diffs in docs, a tool-calling agent over workbook/slide/PDF state in the others. AI providers. The apps sign in to a Genspark account and route model calls through the Genspark service side; no model API key is stored locally. All pure TypeScript, no Electron dependency, unit-tested except the UI kit : packages/docx-engine — docx parsing → block tree with docxIndex anchors and passthrough , OOXML fragment generation, byte-level paragraph patching. packages/pptx-engine / packages/pptx-render — pptx model and rendering. packages/file-parse — text extraction for AI attachments office formats, text formats . packages/agent-core — the AI agent loop and skill composition shared by every app. packages/ai-provider — provider abstraction and streaming for the model backends. packages/ai-search — Genspark auth + web/image search tools. packages/i18n , packages/ui , packages/project-store , packages/electron-utils — shared i18n core, React UI kit, recent-files store, and Electron main-process helpers. npm install npm run fixtures generate test .docx fixtures npm test engine + app unit tests docs/sheets/slides need no display npm run typecheck tsc --noEmit across every workspace npm run dev all four editors + shell against Vite dev servers npm run dev:docs a single app same pattern works per workspace npm run dist:mac package macOS dmg regenerates third-party notices npm run dist:win package Windows nsis installer The sheets app additionally needs a Rust toolchain for its xlsx sidecar cargo on PATH ; npm run build -w @genoffice/sheets compiles it automatically. Local UI/e2e driver scripts Playwright + Electron, for local acceptance, not committed by default live in scripts/drivers/ /genspark-ai/genoffice/blob/main/scripts/drivers/README.md . open docx ─► archive original by hash never touched ─► docx-engine parses word/document.xml top-level elements w:p / w:tbl / … ─► Block tree, each block anchored by docxIndex + original XML slice ─► TipTap streaming editor manual + AI editing, dirty tracking save ─► dirty blocks → OOXML fragments referencing existing styles only ─► splice into original document.xml untouched blocks keep original bytes ─► repack zip; all other entries copied byte-for-byte The same philosophy holds in sheets and slides: the original file is the source of truth, edits are applied as narrow patches, and everything the editor didn't touch survives the round trip untouched.
