Which one would each critic pick
| Critic | Lemon | Pi Agent Desktop | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.3 | Lemon — Pick it if you want an assistant you message from your phone the way you message a colleague; pick a terminal agent if the work never leaves the repository. |
| El Crítico | 5.5 | 5.8 | Pi Agent Desktop — Long-term memory accumulates in a per-project database with no described review, expiry or correction path, so whatever the agent concluded in March is still advising it in September. |
| El Profesor | 6.0 | 6.5 | Pi Agent Desktop — The memory index uses FTS5 trigram tokenisation, which is the correct choice for Chinese, Japanese and Korean text where whitespace does not delimit terms. |
| La Inversora | 5.3 | 5.5 | Pi Agent Desktop — 264 stars, a permissive licence, one author, and a product that is a client for somebody else's agent: the upstream project owns every part a user actually pays for. |
| La Jefa | 5.0 | 5.5 | Pi Agent Desktop — Nothing per seat, and it is the rare tool in this category with prebuilt installers for all three desktop platforms, which turns a rollout into a packaging job. |
| El Hacker | 8.0 | 7.0 | Lemon — MIT, twenty-seven providers plus my own local endpoints, and it speaks the tool protocol in both directions, so it consumes my servers and becomes one. |
