By Tori, last checked 2026-10-08. Each entry below was read against its own page or licence. The verdicts are written for someone who wants to use a tool in something they sell or publish; a skip is often about a licence or a heavy setup, not about quality.

The pattern
Use the official connection, not your login. Review every post before it goes out under your name. Label AI help where the platform asks for it. Read the platform's own rule page; this list is a map, not a licence.
