Changelog

Added open-source disclaimer to Images section explaining that only publicly available images from Wikimedia Commons and similar sources are shown. Helper message now clearly states the limitation to manage user expectations about image availability.

Renamed "Explore" button to "Learn" for better user understanding. The new name more clearly reflects the educational and investigative features it provides (summaries, quizzes, flashcards, deep dive, bias check, timeline, historiography).

"Is Homer's Odyssey Real? What Primary Sources Can (and Can't) Prove." A source-first guide to separating what the text says from what history can support.

Unified 5-button action row on every card: Find Source (blue), Images (purple), Fact Check (red), Explore (green), and Resources (amber). All buttons now consistent in size and styling with color-coded shadows and hover effects.

Images tab now displays actual image thumbnails in a 2-column grid instead of just text links. Added hover effects, error handling with fallback icons, and clickable cards that open full images in new tabs.

Enhanced /api/image-links to fetch optimized 800px thumbnails from Wikimedia Commons API. Prioritizes Wikimedia thumbnails over direct URLs for better quality and faster loading. Supports multi-language Wikipedia pages.

Increased relevance percentage font size from 11px to 18px for better readability at a glance.

Added colons after all metadata field labels (Relevance:, Context:, Author:, Date:, Type:, Location:, Descrip:) for clearer visual separation.

Reduced search button and dropdown button sizes for a more compact, balanced appearance. Mobile: h-8/w-8, Desktop: h-7/w-7.

Increased mobile search textarea right padding to prevent query text overflow when "Secondary" is selected from dropdown.

Added "-- Select a workspace --" empty option to dropdown. Smart field interaction: selecting a workspace clears "create new" input, and typing in "create new" deselects any chosen workspace.

Updated "Add to workspace" modal close button to match app-wide style with SVG X icon and pink hover effect.

Replaced <img> tags with Next.js <Image /> component for better LCP, automatic optimization, and lazy loading of image thumbnails.

Upload PDF, DOCX, or TXT files directly to Sofia for analysis. PDFs are sent as native Claude document blocks (up to 100 pages), DOCX and TXT files are extracted to text. Complements Tavily web extraction for sources that can't be read from URLs. Costs 1-2 credits per upload with 4-hour server-side caching.

Redesigned with inline layout: + button for attachments on left, textarea in center, mic/send buttons on right. All in a unified border with focus-within ring effect. Attached documents persist across conversation turns with a removable badge.

Added icons and detailed tooltips to all Find Resources buttons (Source Links, Peer Reviewed, Citations, Books/PDFs, Blog/Articles, Related Sources, YouTube, Images) and all Explore buttons (Deep Dive, Bias Check, Timeline, Historiography, Summarize, Simplify, Key Points, Podcast, Story Mode, Quiz, Flashcards, Course). Organized Find Resources into Academic Research and Broader Context categories. Added icons to dropdown buttons for better visual clarity.

Added file type detection with color-coded badges showing TXT, HTML, PDF, or DOCX for each result. Green badges indicate Sofia-readable content (TXT/HTML), orange badges indicate downloadable files (PDF/DOCX). Added helpful info box explaining what Sofia can and cannot read from URLs, with guidance to use the + button for PDFs and DOCX files.

Excluded 30+ paywalled domains including bookstores (Amazon, Barnes & Noble), commercial publishers (Elsevier, Springer), and subscription sites (Scribd, Academia.edu, ResearchGate). Implemented balanced categorization returning up to 5 results each of TXT, HTML, PDF, and DOCX files, prioritizing Sofia-readable content first. Results now focus exclusively on genuinely accessible open-access sources.

Credit offer now leads the messaging. Added "Need more credits for testing/researching" as the first dropdown option. Selecting it reveals a card to book a 15-minute Google Meet call for 1,000 credits. Submit row now surfaces the 200 credit reward for written feedback with a note that credits are available within 24 hours and a link to the profile page.

"Why Primary Sources Matter More Than Ever in the AI Era." Covers how AI invents citations, why going back to primary sources is the fix, and how to verify any historical claim.

Rebuilt with a gradient hero, dot-grid background, and card-based feature and differentiator sections matching the homepage. Copy now reflects the actual product (Sofia, Notetaker, workspaces, learning modes, fact-check, podcast, story, quiz, flashcards) with a personal "Why I built it" section in first-person voice.

Added to desktop header after Blog (all users) and to the Learn More card on the profile page (signed-in users).

YouTube links no longer produce a generic "the query references a YouTube video" overview. The system now understands the video's actual content and generates accurate, topic-specific summaries.
