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.

Curation & Accuracy

This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).

Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
