Logos
Careful, multi-step reasoning across long documents. Use it for research questions and comparisons.
Try “Compare how these two papers define the problem, and where they disagree.”
Answers from your sources, with proof.
Upload what you're reading, ask questions about it, and see which passage each answer came from. Then turn it into quizzes, flashcards, or a mind map. Everything stays together as a project you can come back to.

How it works
Four steps take you from a pile of files to answers you can check and material you can study.
Add sources
Attach files, then choose which ones to use. With sources selected, answers are grounded in your material rather than general knowledge.
Pick a model
Choose the model that fits the question: deep analysis, quick answers, health, or finance. The list is the same on desktop and mobile.
Ask and verify
Answers carry source markers such as S1 and S2. Open the Evidence panel to read the exact passage behind each claim.
Keep what matters
Press + Keep to save an answer to the Notebook beside the chat, and edit your notes as you go.
Choose a model
Each model has a different strength. You can switch between questions without leaving the project.
Axiom
Fast, clear answers to general questions about your sources.
Try “What does section 3 say about deadlines?”
Salus
Tuned for health topics: explaining terms, papers, and guidance in plain language.
Try “Explain the results table in this study in plain language.”
Oikos
Tuned for finance topics: reports, statements, and money concepts.
Try “Walk me through the cash flow statement in this annual report.”
Turn reading into practice
Generate study material from your sources with one click, then review what you missed.
Quiz
Scored questions from your material, with focused follow-ups on the ones you got wrong.
Flashcards
Flip cards for key terms and facts, built for spaced repetition.
Mind map
A visual map of how the ideas in your sources connect.
Summary & key points
A short overview, or the main takeaways as a list.
Citations help you check, not trust blindly
Source markers and generated study material are aids to review, not proof. Read the quoted passage and the original file before relying on an answer. Salus and Oikos don't replace medical or financial professionals.
Privacy and limits
To answer a question, Workspace sends the relevant content through our server to the provider for the model you choose. Avoid uploading confidential, sensitive health, or financial records unless you're comfortable with that processing.
Workspace chats, sources, and notebooks are saved separately from main chat and Zen.
Providers set their own shared capacity and rate limits, which can sometimes be lower than your plan allowance. See the Privacy Policy for storage and provider details.
