Instinct says 40% of users grant credit card access within three weeks as founder admits early version lacked firewalls

Instinct founder Noah Shinn said about 40% of users allow the product to use their credit cards after three weeks, letting its agent complete purchases on their behalf. He said the company tracks how long it takes before users first share sensitive information such as credit cards, account passwords, or other credentials as a measure of trust. Once a user connects at least one piece of sensitive information, retention is about 80%. Shinn also acknowledged that Instinct’s early version did not have the firewalls and active monitoring systems now in place, and that the product made mistakes. He said the company later rebuilt its security architecture instead of patching isolated issues one by one. Under the current setup, text, images, and other content are screened by an independent firewall before being handled by the agent, while a separate system monitors planned actions and parts of the model’s reasoning so they can be paused or blocked before execution. Shinn was also responding to a prior user report that Instinct had started processing a financial document the user said had never been uploaded. He said the incident was a hallucination in which the model fabricated information and then fabricated an explanation, not a user data leak. Instinct later launched a standalone hallucination detection system to check and intercept anomalies before the agent continues reasoning or calls tools.

Reverse engineering suggests Instinct stores long-term memory in Git-managed Markdown files

Supermemory founder Dhravya Shah said his reverse engineering of the personal agent assistant Instinct points to a long-term memory design built around Git-managed Markdown files rather than replaying entire chat logs into context. In Shah’s account, Instinct keeps an up-to-date user state, then uses a separate file-based store for more detailed records such as preferences, decisions, tasks, and person-specific facts. His black-box testing suggested that each conversation begins with a user state summary of about 4,250 tokens, covering background, operating preferences, and communication habits. Shah said he did not find signs of vector indexing or BM25 retrieval. Instead, detailed memory appears to be fetched with keyword search similar to grep, while a background process continuously reorganizes information: temporary details are grouped under tasks, experiences are distilled into long-term preferences, old facts are revised with new ones, and Git preserves version history. He added that the main agent appears to focus on reading memory, while the cleanup and merge work happens in backend workflows that he estimates run about once a day. According to Shah, the setup is close to Supermemory’s own view of how agents should manage memory, and he said the architecture can be largely replicated with Supermemory. He shared an example that used roughly 60 lines of code to plug user profiles, memory search, version history, and continuous updates back into an agent.
