Contact the teamWhat every plan includes
The same calm tutor, with more room to use it.
Every Socrates account ships with the same editor, the same Socratic teaching style, the same recall system, and the same knowledge map. Plans differ in how much you can use them, not in how they teach.
Teaching
Socratic dialogue with streaming responses.
The tutor asks before it answers. Responses stream as you read, with LaTeX, code, and diagrams rendered inline so you stay in the idea.
Recall
A small prompt queue that returns ideas on schedule.
Save a moment from any session, and the tutor brings it back at the right interval. Your recall history stays private to your account.
Models
The right model for the question.
Pick a fast model for a quick clarification or a deeper one for a long thread. Bring your own provider key from the API Keys page if you prefer.
Privacy
Your thinking is yours.
Sessions are private to you. We do not train on your conversations. Export or delete any session at any time from the account page.
Choosing a plan
Three honest questions.
Most people do not need to think about this for long. If you can answer the three questions below, the rest is just a number.
Question one
How often will you open a session in a week?
One or two sessions a week? Start with Free or Riemann. Daily study across two or three subjects? Descartes is the right size. Full-time learning or research? Euclid.
Question two
How long do your sessions tend to run?
If most sessions are short and focused, the lower plans hold up. If you tend to walk through entire chapters in one sitting, you will want more headroom for tokens.
Question three
Will you use exam mode or web search?
Exam mode, web search, and the highest limits live in Descartes and Euclid. If those matter to the way you study, plan for them from the start.
Pricing questions
A few things people ask before they subscribe.
Cancellation
Can I cancel any time?
Yes. Cancel from your account page and your plan stays active until the end of the period. There are no retention calls and no cliff dates.
Switching plans
What if I want to switch later?
You can move up or down from the account page. Upgrades take effect immediately, and we pro-rate the unused portion of your previous plan.
Refunds
What if I change my mind?
If you cancel within fourteen days of a first paid plan, write to us and we will refund the period. We would rather you leave with a good impression than a credit on file.
Students
Is there a student discount?
Yes. Send a note from your academic address to help@addtech.site with a course name and your institution, and we will send a discount code.
Invoices
Do you support invoices and VAT?
Yes. Add billing details from the account page and every charge arrives with a downloadable invoice. EU customers are billed with VAT applied where required.
Teams
Do you offer a team plan?
Not yet as a self-serve plan. We work with research groups, classes, and small companies on a per-team basis. Use the contact page to start the conversation.
