    Extend UI is now approaching 2M monthly npm downloads 📈 - fully open source (MIT licensed) - 1.6k GitHub stars - officially supported by our team many of the largest AI startups/enterprises already use it in production if you're building anything where users interact with documents, there's probably something in here you need: - DOCX editor & viewer: rich text formatting, comments, tracked changes, tables, images, import/export - PDF viewer: text selection, search, page thumbnails, zoom, rotation, and bounding box overlays - PDF editor: highlights, annotations, comment threads, redaction, form filling, and page reordering - XLSX viewer + editor: sheet tabs, formulas, cell formatting, frozen panes, merged cells, and export - PPT viewer: in-browser slide rendering, thumbnail navigation, and zoom - CSV/TSV viewer: virtualized grids for large datasets, search, and cell navigation - source citations + extraction review: connect extracted fields to bounding boxes in the original document, edit values, and compare JSON outputs - schema builder: visual editor for extraction schemas, nested objects, arrays, enums, and a synced JSON view - document splitting: drag pages between groups and reorder them with page previews - e-signatures: signature and initials placement, date fields, required-field checks, and signed PDF export - file browser: Finder-style folders with icon, list, column, and gallery views - file uploads: drag-and-drop, batch uploads, validation, progress, and retry states - file thumbnails: preview tiles with loading and fallback states - OCR + layout inspection: block, line, and word overlays with confidence coloring and navigation back to the source page

    Excited for this launch - Verify runs on specialized tamper and AI fraud detection models trained on 1m+ pages of fake documents
    Kushal Byatnal @kushalbyatnal
    AI-generated fake documents grew 500% last year, and humans can no longer tell the difference That's why we’re launching Extend Verify, the first document fraud detection API built for agents Verify catches the fastest growing types of document fraud, including: - fully AI-generated documents - localized AI edits (down to a single modified character) - patched text, overlays, and in-painting from Photoshop, PDF editors, and coding agents - digital tampering after a document was signed - and many more In our internal evals, Verify detected over 96% of AI-generated and tampered documents. Verify is available today:

    RT @kushalbyatnal: introducing operator-1, an autonomous document extraction agent operator-1 saturates multiple 3rd party benchmarks, and delivers the most accurate performance on complex tasks that other solutions can't handle: > long tables with thousands of rows > lengthy files with context scattered across hundreds of pages > dense diagrams and images > much more! operator-1 is a specialized agent we built that: - runs within a custom workspace - knows how to use dedicated tools (parse, search, zoom, code execution, validation) to handle any document - learns via persistent memory

    every company has a shared drive nobody can find anything in we built a doc library that files itself and answers questions with the exact page + citation it's called jevbox. built on extend parse + jev. and it's open source. a few ways to use it: - contract library for procurement and ops - due diligence dataroom for VCs - policy and compliance reference for HR - clean context for your agents MCP included with authz built in (think google drive permissions) self-host it or one-click deploy to render, instructions are in the repo. link in the comments!

    RT @ExtendHQ: Today we're shipping Parse Auto-Router: it picks Light or Performance Parse for every page in a document, so you don't have to. Clean pages go to Light, hard pages go to Performance. Set engine to parse_auto to try it today.

    Edit fills PDF forms programmatically, with or without embedded fields. We've improved detection on low-quality scans and skewed pages, made field labels more consistent, and redesigned filling to better handle corrupt files, revisions, and signatures. The new form detection model is fine-tuned from the layout model behind Parse. Great to see our AI/ML team's work compound across products! @ameyaajoshi @joon_kim96
    Extend @ExtendHQ
    Our Edit API got a major upgrade with a new forms model delivering: > better field detection, labeling, and filling > improved corrupt PDF handing > verifiable signatures that survive revisions check it out and try it on your docs!

    maybe just me but noticing coding agents have been patching libraries more frequently fable found a bug with older versions of next js swc and regex code, components would render fine locally but not in production builds

    RT @ExtendHQ: today, we're shipping Extend Templates: 50+ document types, ready to go. every template comes with the pipeline, processor settings, schema, sample document, and expected output already figured out. until now, teams rebuilt all of that every time, based on vibes and whatever expertise was locked in someone's head. point your coding agent at one, import it into your Extend account, or fork it on GitHub. browse the library and find your document type!
    Victor Dubeux @victordubeux
    just shipped @ExtendHQ Templates with @andrewlu0!!! 50+ pre-built doc processing pipelines + a smart search library. We noticed AI teams ran into similar challenges, like the 12-page EOB w/ nested tables, or the bad receipt scan. Now they can solve them with Extend in <1 minute. — every page is agent-readable, so you can point Claude Code or Codex at one and the template ships itself — import into your Extend account in <10s — fork it, or grab the client code in TS / Python / Java / Go Check it out! It's live now at
