Choose a prediction-market AI tool by the job you need to complete: investigate a contract, evaluate a forecast, monitor wallets or build a data integration. These are different workflows. Alphascope is our product; this is a disclosed comparison of approaches, not an independent accuracy ranking or a funded trading test.
Research approaches compared
| Approach | Useful task | Limit to check |
|---|---|---|
| Alphascope | Odds, market-linked research and forecast context | Source freshness, exact contract selection and uncertainty |
| Polifly | Advertised screenshot analysis, wallet tools and paper workflows | Live account feature availability and execution assumptions |
| Forecasting reference | Compare an independent question and probability | Whether its wording and deadline match your contract |
| General AI assistant | Extract documents and challenge a thesis | Whether it retrieved current evidence instead of relying on memory |
| Native exchange API | Retrieve venue-specific market data for a custom workflow | Engineering effort, authentication and schema changes |
Evaluate the same contract in every tool
Save the contract rules and a quote timestamp. Give each tool the same question. Record its probability before resolution, what evidence it cites, and what it says could change its estimate. Count missing sources and mismatched contracts as failures, rather than silently substituting easier examples. This is an evaluation protocol you can use; it is not a report of tests we performed.
A worked economic comparison
Suppose two tools give 58% and 65% for the same hypothetical $1 binary contract. The executable ask is 60¢ and estimated costs are 2¢. The first estimate implies −4¢ EV per contract; the second implies +3¢. Neither number establishes which model is correct. The disagreement is a reason to investigate the evidence and stress-test the probability in the EV calculator.
Compare price and limits at the source
Polifly's public page displayed an introductory $29 monthly offer when checked on October 5, 2026; actual checkout and renewal terms were not tested. Our source-based review records the verification limits. Use each vendor's current checkout for price and plan limits rather than assuming a promotional headline is a permanent rate.
When an API is the better fit
A custom data workflow can be appropriate when you need reproducible records, your own model or deeper integration. Start from the Polymarket documentation and Kalshi market-data guide. Data access is not a forecast, and an SDK is not a profitable bot. Read the API comparison and bot evaluation guide before implementing execution.
What makes a tool worth keeping
Keep the tool if it reduces a measurable research task without hiding uncertainty: fewer missed rule exceptions, easier source tracing, faster retrieval or a forecast record you can audit. Reject unsupported performance claims and simulated results presented as actual returns. Track subscription cost separately from trading results so a useful research interface is not mistaken for evidence of financial edge.
