The three tiers
The panel states the model in one line:Profile is injected every turn. Log is dated history. Notes fade after two days.
Each entry has a length ceiling: a Profile entry can be up to 4,000 characters, a Log or Note entry up to 500.
What memory does during a turn
Memory is injected, not retrieved. There is no relevance search that goes looking for the right entry, so the profile lines are in front of the bot whether they matter to this job or not. That makes Profile valuable space: a handful of sharp lines works better than a long dump. Memory also survives a long turn. When a turn accumulates enough transcript the bot rewrites its own working context to keep going, and the Profile is one of the things it keeps, along with the open question and any open work. A bot does not forget who you are because the job ran long. See How Bot works. Because memory belongs to the bot rather than to a thread, it travels everywhere that bot speaks: a message you send, a run a routine started, a skill you ran directly, and any channel the bot is a member of.Add and remove an entry
Open the bot and go to its Memory panel. A bot that has not remembered anything yet readsNothing remembered yet., and while the list is being fetched you see Loading memory….

Write the fact
The field asks
What should it keep? Write one fact in plain language, the way you would tell a colleague.2
Choose Remember
Remember saves it. If the write fails you get
That memory could not be saved. and nothing is stored, so you can try again.3
Delete what is no longer true
Delete removes a single entry. This is the only way to clear memory: there is no button that empties everything at once, so a bot with a lot of stale history is tidied entry by entry.
The bot writes its own memory too
Remembering is one of the bot’s own tools, and it is one of the tools that never stops to ask for approval, so a bot can record something mid-job without parking the turn. Telling it in the conversation to remember or to stop relying on something is enough, and the bot chooses the tier. Writes are deduplicated, so a bot cannot fill its Profile with the same sentence over and over. What it cannot do is decide for you what should be forgotten, which is why the panel keeps Delete in your hands.Only you can see what your bot remembers. Memory is never carried into a copy of a bot: the share preview lists Memory among the withheld sections, and Cortex is explicit about why.
Memory, secrets and the computer are withheld by name rather than dropped silently — an omission you cannot see is a decision you did not make. See Share a bot.How this differs from Chat memory
Cortex Chat has memory as well, and the two are separate systems that do not read each other.
Adding something to one does nothing to the other, and clearing one leaves the other untouched. If a fact should follow a bot into scheduled work at three in the morning, it belongs in Bot memory. If it is about how you want a particular conversation to go, it belongs in Chat memory.
