Study Harbors

Study Harbors is a private course workspace for turning source material into an organized plan for learning. PLAN BY COURSE Create separate course workspaces with codes, exam dates, weekly time targets, and color identity. Break the work into learning objectives, then track urgency, priority, progress, and confidence without mixing unrelated classes together. KEEP EVIDENCE WITH THE CLAIM Capture a source title, locator, source type, summary, connection, and tags in one evidence note. Notes stay linked to their course so the context behind an idea remains available when it is time to review or write. PRACTICE RETRIEVAL Build questions from your own material and review them in Recall Studio. Reveal the source-backed answer, grade the effort, and let the on-device interval engine schedule the next review. Upcoming prompts remain visible so the queue is understandable rather than hidden. RUN FOCUSED STUDY BLOCKS Choose a course, name the intended result, and start the built-in focus timer. Afterward, record what changed. Seven-day charts and course allocation show where study time actually went compared with each weekly target. OWN THE RECORD Export a readable study packet, a focus-session CSV, or a complete JSON backup. Restore a backup when needed. Study Harbors requires no account and includes no ads or third-party analytics. Courses, objectives, evidence, recall schedules, and focus sessions stay on the device unless you deliberately share an export. Study Harbors is an organization and learning-practice tool. It does not complete assignments, guarantee outcomes, or replace guidance from an instructor.
