Almanac is a HIPAA-compliant AI workspace built for healthcare professionals. Ask clinical questions, review evidence, work with patient context, analyze research, and create finished documents and presentations from one place. FIND CLINICAL EVIDENCE Ask about treatment guidelines, differential diagnoses, medications, trials, or the latest literature. Almanac searches trusted clinical sources and the medical literature, synthesizes the evidence, and shows you the sources behind its answers. MANAGE YOUR PATIENTS Connect your EHR to bring relevant patient information into the conversation. Review medications, labs, allergies, notes, and history while keeping the clinical question and patient context together. COLLABORATE ON RESEARCH Upload papers, datasets, images, and other files. Almanac can inspect study methods, compare evidence, analyze data, run code, recreate figures, and help you work through complex research questions. DELEGATE YOUR WORK Create presentations for rounds, draft clinical summaries, prepare patient education materials, analyze spreadsheets, generate reports, and work across documents without leaving the conversation. Under the hood, Almanac can use tools, write and run code, search the web and medical literature, work across files, and carry out multi-step tasks while you remain in control. Built for healthcare organizations with HIPAA-compliant infrastructure, enterprise authentication, access controls, and audit-ready workflows. Almanac supports clinical judgment and does not replace the judgment of a qualified healthcare professional.

About

DiagnoseThis

You've been dismissed. Misdiagnosed. Told your labs are "normal" when your life is not. The DiagnoseThis app is where that stops. Diagnose This is the only health community built around one radical idea: you deserve to know WHY. Why you feel the way you feel. Why your symptoms connect. Why your body is sending signals no one has taken seriously — until now. Inside the DiagnoseThis app, you get: — Chat WHY — a free, living community of health rebels and real clinicians who actually listen. Ask questions. Share your story. Stop carrying this alone. — Ask WHY — a clinician-designed symptom assessment that maps patterns across your body's five systems and starts connecting dots your doctor never did. — SEE WHY — visual pathway maps, lifestyle guidance, and lab considerations that turn confusion into clarity you can act on. — THE WHY — your full, printable clinician-ready report. Evidence you can walk into any appointment with. A document that speaks the language medicine understands. This isn't a wellness app. It's not a forum. It's a movement — backed by real clinical frameworks, built for people who are done Googling symptoms at 2am and coming up empty. Join WHY Fighters who stopped accepting "we don't know" as an answer. The room is open. Diagnose This is free to join. DiagnoseThis is for information and education only. It does not provide medical advice, diagnosis, or treatment, and it is not a substitute for a qualified healthcare professional. Always talk to your doctor about your health.
