Sen is the personal AI chatbot you build yourself. Upload your documents, train your expert, and keep every conversation completely yours.
Train your Sen on anything you know. The more you teach it, the smarter it becomes about what matters to you.
PDFs, books, research papers, clinical notes, articles — Sen reads and understands them all. Drag, drop, done.
Sen learns from your unique knowledge base, building deep expertise in your chosen field — not generic internet data.
Ask complex questions, request analysis, get summaries. Sen answers with context from YOUR materials, cited precisely.
Add more documents any time. Your Sen evolves as your knowledge grows — from student to researcher to world-class expert.
Powerful enough for researchers. Simple enough for first-year students.
Chat with other Sen users with full end-to-end encryption. Share insights, collaborate on cases, or consult colleagues — with zero visibility to anyone else, including us. Your messages are yours, always.
E2E EncryptedPDFs, DOCX, TXT, RTF — Sen digests them all and builds your knowledge layer on top.
Name your Sen, set your colour palette, change the background, make it feel like yours. It's not just functional — it's an extension of you.
Upload 200 papers and ask Sen to synthesise the evidence, find contradictions, and surface insights — in seconds, not weeks.
For researchersEvery user gets a private, isolated environment. No shared models. No cross-contamination. Your data never trains anyone else's AI.
Full isolationThe medical world generates more knowledge every day than any person can absorb alone. Sen doesn't replace your expertise — it amplifies it, pulling from exactly the materials you've chosen to trust.
Your research. Your notes. Your clinical experience. Turned into an always-available expert at your side.
Upload your textbooks, lecture slides, and exam notes. Ask Sen to explain complex pathophysiology, quiz you on pharmacology, or summarise a topic the night before an exam.
Train your Sen on your specialty. A cardiologist's Sen becomes an expert in heart failure. A surgeon's Sen knows every step of their procedures. Your knowledge, always available.
Upload hundreds of papers. Ask Sen to find consensus, spot gaps, analyse methodology, and surface insights across your entire literature base — instantly.
Give every clinician their own private Sen, trained on institutional protocols, formularies, and guidelines. Consistent knowledge, personalised access.
Every Sen user lives in their own isolated, encrypted container. We don't have access to your documents, your conversations, your training data, or your messages. Not even us. That's not a promise — it's the architecture.
Your Sen isn't a generic chatbot. It carries your name, your colours, your personality. When you or your students open it, they know instantly who built this and what it knows.
Try Sen with no credit card. Upgrade when you're ready to train your first expert.
