What do you do (can we do something else than markups and recipes ?) Does it work fine for you ? Which AI do you find is the best for this kind of work ?</div><div class="gmail_default" style="font-family:monospace"><br></div><div class="gmail_default" style="font-family:monospace">Gilles.</div></div>
