Changelog

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.

Sharpened the introductions for the search bar and Sofia so the difference is clear: search bar for finding sources, Sofia for asking questions.

Fully redesigned blog page with a cleaner reading experience, featured post, and a post grid. Built for weekly publishing with practical guides on primary source research, fact-checking history, and using AI in research workflows.

Added a How It Works link in both the desktop sidebar and the mobile menu, so you can jump back to the walkthrough anytime.

The suggested questions on the search page no longer auto-rotate every few seconds. Use the new "Shuffle questions" button to get a fresh batch when you want one. Clicking a suggestion only fills the search box now; the rest of the pills stay put.

The message input and send button no longer hide behind the bottom tab bar. The chat panel now sizes itself to leave room for the Search/Notetaker/Library nav.

Full redesign explaining the app step by step: search bar with query examples, source cards with button explainers, Sofia capabilities at every stage, Notetaker with mock editor, and a "Who it's for" section targeting students, history enthusiasts, teachers, and content creators.

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.

To reduce AI hallucinations, a new verification step now cross-references every source against the live web before showing results. Verified sources appear first, so you can trust what you see.

Send any source card directly to the Notetaker from the + menu. Sofia automatically gets context about the source so you can ask her to write, summarize, or analyze without copy-pasting.
