Your 100ms performance target will fail if you parse the entire 10-page document on every keystroke instead of implementing incremental tokenization. This becomes critical when users paste large code blocks with nested syntax rules. Quick questions - are you planning to store media inline as base64 or reference external files with a manifest system? And what's your expected concurrent user count if you move to web - single-user local app or multi-tenant cloud editor? Here is the architectural approach: - C# + WPF: Build the Windows desktop core with incremental parsing using Roslyn-inspired tokenizers that only re-highlight changed lines, keeping UI thread under 16ms per frame. - FLUTTER: Share business logic via platform channels to native Swift/Kotlin for video trimming (AVFoundation/MediaCodec) while Flutter handles cross-platform UI and document state management. - REACT NATIVE: Implement the plugin API as a JSON-RPC bridge so third-party content types register handlers without recompiling the core editor, enabling extensibility you need for future formats. I've built similar hybrid editors for 2 enterprise clients where desktop performance and mobile feature parity were non-negotiable. Let's schedule a 20-minute architecture review to align on your media storage strategy before you commit to a framework.

The key to this project is not building three separate editors — it’s creating one shared document engine that behaves consistently across desktop and mobile. I’d structure the app around a platform-independent document model, with reusable editor components and platform-specific UI/rendering where needed. For the first version, I’d approach it with: A shared content/document layer for text, code, images and video Monaco/CodeMirror-style syntax highlighting with incremental updates for the <100 ms target Rich-text editing with headings, links, tables and inline media Local spell-check dictionaries with asynchronous checking so typing never blocks Image crop/resize/metadata operations Video trimming, thumbnail capture and preview A plugin/API layer so new content types can be added without rewriting the editor Automated tests covering mixed-content documents and media operations I’d also make the build pipeline reproducible from day one so Windows, macOS, iOS and Android can each be compiled with a documented single command. One important question before development: do you already have a preferred desktop/mobile stack, or are you open to choosing it based on which approach gives the best shared-code coverage and editor performance?

Sharing a single document model across Electron and React Native is where most cross-platform editors quietly break, the tree has to be serialisable, not view-bound. I'll build the core on a shared TypeScript model (Yjs or Slate JSON), wrap it in Electron for desktop and React Native with a native bridge for mobile, and expose a plugin API so new content types slot in cleanly. Monaco handles syntax highlighting on desktop; mobile needs a lighter shim to hit sub-100ms. 1) Is offline editing with later sync required, or online only? 2) Which languages must the spell checker cover at launch? Cheers Shayan

@aakaashberi

You invited scope challenges, so here is the real one: a professional editor with syntax highlighting, rich text, spell check, image editing and video trimming, across desktop and mobile, with a plugin API, is a product rather than a fixed-price build. My bid buys phase one - the document model and the text editing core - and the rest gets priced from there. Three things decide the architecture. Your acceptance criterion 2 is the hard one. Sub-100ms on a ten-page document means highlighting and spell check cannot re-scan the whole document on every keystroke - they tokenize incrementally, only the changed region, and run off the UI thread. Naive full-document re-highlighting misses that target long before ten pages. Criterion 1 conflicts with your stack list. Electron or WPF on desktop plus React Native or Flutter on mobile means two editor implementations and two sets of bugs, and parity becomes a permanent tax. Parity comes from sharing one core - document model, tokenizer, spell check - behind thin native shells. Video: trimming has to be non-destructive. Store the source with in and out points in the document and render on export, or every trim re-encodes, quality degrades and undo stops working. Rs 12,500, 4 days for phase one, with the plugin interface defined up front so later content types drop in rather than get bolted on.

Hi, I’d be interested in building your cross-platform all-in-one content editor with a modular architecture that can support future web and plugin/content-type expansion. I’d recommend Flutter for the mobile experience and Electron for desktop, sharing core models/business logic where practical while using platform-specific components for performance-critical editing tasks. I can implement mixed-content documents, real-time multi-language syntax highlighting, rich-text formatting, links/tables/inline media, multilingual spell checking, image crop/resize/metadata editing, and video trimming, thumbnail capture, and preview. I’ll prioritize responsive editing performance and use efficient document/state management to target the <100ms interaction requirement on a 10-page document. The project will include clean UI/UX across platforms, export handling, automated tests/demo scripts, linting, build instructions, documentation, and an extensible API/plugin architecture. I’d suggest defining the supported languages, document format, and export requirements first so I can provide an accurate architecture, milestones, and timeline.
