Editor’s pick Hands-on review

Quartr brings together earnings calls, transcripts, filings, reports, and slides into one platform. The free mobile app is consumer-friendly, while Quartr Pro (desktop) and the API are enterprise products sold on a custom basis. The API is generous—paying customers get effectively unlimited calls, demo accounts are capped, and a 50 rps global rate limit goes into effect in December 2025. Live audio and transcripts are delivered in real time, making it a go-to tool for analysts who don’t want to wait.
