Pricing compared
Both products are freemium, but specifics for paid tiers are undisclosed. Gem targets companies with 101-1,000+ employees, so likely has per-seat or usage-based plans for ATS/CRM and AI agents. Second Brain likely charges for advanced features like larger storage or multi-app cross-search. Without precise numbers, the decision hinges on value: if you need a full recruiting stack vs. a personal assistant. Gem claims 30-50% cost savings over multiple point solutions, which may justify its price for growing teams. Second Brain's on-device model avoids cloud subscription costs, but paid tier may be minimal for individual users.
