🔐 Lock a private chat with a PIN — any chat with a friend can now be closed with a 6-digit PIN: chat menu → Lock. A locked chat shows a padlock in the list and nothing but a lock screen until the code is entered, the same way My Intro and My Rules already work. Handy for the moment you hand someone your phone.

🧠 Your Memory Tree now learns from any chat — facts you mention in ordinary conversations — family, places, work, dates that matter — are remembered too, not just your declared interests. Tell the app something about yourself anywhere and it lands in the tree; going through Intro first is no longer required.

⚡️ Memory answers got faster and cheaper, at the same quality — the app no longer sends the same memory twice, skips an extra AI call for lookups on small trees, and shapes requests so providers can cache the stable part. An interrupted reply is no longer charged twice either.

🧹 The Memory Tree keeps itself tidy — duplicate links and repeated facts stop piling up, and records you rename or merge update in semantic search immediately. A smaller tree means sharper memory-backed answers.

🧠 The Digital Brain organizes itself — new memories pick their own hemisphere, and the map arranges them by meaning, so related memories gather into clusters instead of scattering. Long conversations also get a rolling summary, so the model keeps the thread of a long talk.

🤖 Kimi joins the main model menu — Kimi used to live only in Programming mode; now it's in the regular model picker and follows your Quality setting: Maximum quality runs the Kimi 3 flagship, Speed and Economy switch to the faster, cheaper Kimi K2.7. Worth knowing before you switch: Kimi 3 is priced like Sonnet or GPT-5.4, and K2.7 costs three to four times less — for everyday work Speed or Economy is the better value.

⏳ Incognito waits for the whole generation — a long job, like a video from a photo, no longer gets cut off. The chat waits as long as it needs and shows you the finished result, exactly like a normal chat.

💬 A generation that produced nothing tells you why — if the model couldn't make anything from your request (for example, a plain question typed while in image mode), the message now explains what happened and asks you to describe the result you want.
