Invisible Improvements, Stronger Foundations

Security Foundations

This release is different from our usual updates - almost everything in it is invisible. Over the past few weeks we've rebuilt the security foundations underneath Conception, strengthening how your data is authenticated, isolated, and tracked. You won't see new buttons, but everything you create is now protected by multiple independent layers.

Stronger authentication. Every request between the app and our API is now verified using cryptographically signed tokens issued when you sign in. Identity is checked end-to-end on every call, so the API always knows - and verifies - exactly who is asking before touching any data.

Isolation enforced at the database layer. Your notes, chats, and databases are now protected by row-level security directly inside the database itself, in addition to checks in the application. Every read and write is scoped to your organization at the lowest layer of the stack, so even in the unlikely event of an application bug, data can never cross from one tenant to another.

Introducing organizations. Under the hood, workspaces now live inside organizations - a new top-level boundary that owns every piece of data you create. Today this happens automatically and changes nothing about how you work, but it lays the groundwork for what's coming: teams, member roles, and shared workspaces, all built on a foundation where access control is explicit from day one.

A complete audit trail. Every meaningful change - creating, editing, or deleting notes, chats, databases, and account settings - is now recorded in an append-only audit log that even we can't modify. This is the kind of accountability infrastructure that larger teams and compliance frameworks (like SOC 2) expect, and we're building it in early.

We treat the security of your ideas as a feature, not a checkbox. More of this foundational work is on the way.

AI Model Updates

We've continued expanding the range of AI models available in Conception. Claude Opus 4.8 and xAI's Grok 4.3 are now available for Pro and Premium users, giving you access to stronger reasoning, improved writing quality, and a broader set of tools tailored to different workflows and use cases. Our goal remains to provide flexibility and choice, so you can select the model that best fits the task at hand.

Earlier this month, we also introduced Anthropic's Claude Fable 5 before subsequently removing it for affected users due to a new U.S. export control directive requiring Anthropic to suspend access to Fable 5 and Mythos 5 for foreign nationals. While this interruption was outside our control, we remain committed to transparency around the models available in Conception - including how they handle data and any limitations that may apply - and we'll restore access to Fable 5 immediately should it become available again.
