In depth comparison
Letters and Reviews
lettersandreviews.blogspot.com
Free, personal curation site that aggregates **fund manager letters**, tickers mentioned in those letters, and **quarterly 13F** filer lists the author follows. Each quarter page links to original letters and maps tickers to quick‑reference pages; some 13F pages embed holdings tables and activity (new/increased/decreased/sold) for many managers. Also includes a small **Podcasts** list. No accounts, alerts, exports, or API—think link‑hub for primary sources rather than a data platform.

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 Pricing, features, and availability may be incomplete or out of date.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.
