What’s new

This week brought credits for AI use, a floating chat for asking questions about articles, email sign-up, better-organized topics, and a fix for topics that got stuck while generating.

1. New

   Pay for what you use, with credits

   SophistAI now runs on credits, so each plan includes a monthly amount and small packs add more when you need them. New accounts start with 300 free credits that never expire, and a one-tap top-up appears when you run out.

2. New

   Ask follow-up questions in a floating chat

   Asking a question no longer takes you away from the article. A chat card floats over the page with one question and answer at a time, and each answer suggests follow-ups you can tap. On a phone, the card stays clear of the keyboard.

3. New

   Sign up with an email and password

   You can now create an account with just an email and password, not only with Google. A verification link confirms your address, and a reset link helps you get back in if you forget your password.

4. Improved

   Articles read like a book and skip repeated topics

   Each article now knows the whole subject outline, so it won’t re-explain a section that already has its own topic. Articles also avoid phrases like “see the diagram”, so they make sense on their own.

5. Improved

   Big syllabi are grouped into clear sections

   Subjects with many top-level areas are now split into groups of about 4 to 8 topics under short parent topics, instead of one long flat list. The topic tree is easier to scan and study from.

6. Fixed

   Stuck topics recover, and retry is one click

   Topics that froze while generating are now marked as failed instead of spinning forever. Opening a failed topic no longer retries it by itself, so you choose when to try again with a single click.

This week added a public pricing page with plans and short Max passes, made moving between pages faster, and gave shared subjects branded preview cards.

1. New

   See plans and prices on a public page

   A new pricing page lists every plan with its features and prices, so you can compare options before signing up. Chat is part of Pro and Max, while Starter covers articles and uploads.

2. New

   Short Max passes for 30 or 90 days

   You can buy a one-time Max pass for 30 or 90 days instead of a monthly subscription. It gives full Max access until the pass runs out and does not renew on its own.

3. New

   AI tools now run on a plan

   AI features such as generating articles and chatting now need an active plan, pass or grant. Public and shared subjects stay readable without signing in.

4. Improved

   Free users get a clear path to plans

   When a feature needs a plan, the message now includes a See plans button that takes you straight to the pricing page. People who already have a plan through an institution or pass are no longer shown the upgrade prompt by mistake.

5. Improved

   Shared subjects get branded preview cards

   When you share a subject or article link, it now shows a preview card with a title, topic list and short summary instead of a blank link.

6. Fixed

   Moving between pages is quicker

   Clicking between pages no longer waits on a fresh sign-in check each time, so navigation in the app feels much less frozen. Pages like pricing now open right away.
