Turn public prediction market signals into a repeatable research practice. PolyTerminal combines a read-only market browser with a private workspace for your own estimates, evidence, and review plan. Explore active questions, study probability history and movement, and keep each decision in context. Explore the public market: - Browse trending, high-volume, moving, and ending-soon questions. - Search by title, combine filters, sort results, and save presets. - Review YES and NO probabilities, historical charts, volume, liquidity, order book levels, and recent public activity when available. - Save timestamped snapshots to compare what changed. Build your own view: - Record a personal probability, direction, confidence, thesis, counter-evidence, tags, and checklist. - Arrange notes, predictions, snapshots, checklists, and reminders on a flexible research board. - Keep a watchlist and compare your latest estimate with available market data. - Schedule time-based local reminders and weekly reviews. Practice without a connection: - Keep an offline forecast journal with a question, YES probability, thesis, and optional review date. - Preserve revision history, resolve each forecast as YES or NO, and reopen it when needed. - Review resolved counts and mean Brier score with an in-app explanation of how the score works. - Convert decimal odds to implied probability and compare probability changes in percentage points entirely on your device. - Journal, calibration, and calculator features remain available when public market data is offline. Private by design: - Your notes, estimates, board, watchlist, presets, snapshots, and reminders are stored on your device. - No account, wallet, advertising, analytics SDK, subscription, or in-app purchase. - Public market requests are read-only. Your personal research is never included in those requests. - Sample mode provides clearly labelled fictional data when you want to explore without public results. PolyTerminal is a research and productivity tool. It cannot place orders, execute trades, connect a wallet, hold funds, or provide financial advice. Public data can be delayed, incomplete, unavailable, or restricted by its provider. Verify source information independently before making decisions.
