Alternatives to Ember

Ember is a daily AI prediction engine that runs three genuinely different AI models—Claude from Anthropic, Grok from xAI, and Gemini from Google—on live Polymarket markets every morning at 7AM EST. The models make their calls independently before the markets resolve, and their predictions are timestamped and publicly tracked for accuracy. Ember stands out because it refuses to edit anything after the fact, even posting post-mortems on wrong calls to build trust through full transparency.

Ember is built for traders, degens, and market nerds who want AI-driven signals on Polymarket events without any of the shady black-box nonsense. If you’re the type who needs to see the receipts—like timestamps, Brier scores, and calibration data—before you trust a prediction, this is your jam. It’s also perfect for anyone who loves watching models compete in real time, since the three AIs disagree with each other and flag high-conviction signals when they diverge from the crowd by 10+ points.

Based on the provided product content, there is no mention of a specific pricing model, so it’s unclear whether Ember is free or paid. The description focuses entirely on the public, transparent nature of the predictions and the tracking system. You would need to check the official Ember platform for current pricing details or any subscription tiers.

Ember’s main features include three independent AI models (Claude, Grok, and Gemini) making daily market calls on Polymarket at 7AM EST, with every prediction timestamped before the market resolves. It uses Brier scores to track accuracy and calibration, and flags high-conviction signals when any model disagrees with the crowd by 10 or more points. The platform also publishes post-mortems on every wrong call and maintains a public, uneditable record of all predictions over a 365-day period.
