The useful part of a conversation should not disappear when the window closes.
Work accumulates in chats, notes and records. When a fact changes, the earlier statement should remain inspectable. MemStrata keeps that material close to your machine and lets you open the source behind an answer.
10 Mar Project review is on Tuesday afternoon.
12 Mar Correction: the project review moved to Friday.
Four products
Choose the product that matches the job
Memory, changing records and source inspection are the jobs. Each product below is one of those jobs, with a direct next step.
Conversational
A conversation with your own context
Keep useful memory across chats and documents. Keep useful context across conversations. Bring your own reader.
Illustrative example. Ask tab: the review is on Friday, with a source link to the correction note. Sources tab: original Tuesday note and Friday correction. What changed: the two entries in date order.
Coder
Project context inside your coding tools
Give a coding tool relevant project context. Give your coding tool focused project context.
Placeholder schematic. A repository question, selected files and a context receipt. Capture a native Coder screenshot before treating this as product UI.
Structured
Operational answers with a record behind them
Report on current and historical records. Ask your operational records what is current and what changed.
A detected installation is not automatically reporting. The policy decision is recorded with the observed action.
host: local-agent · policy: write-review-v3
Local workspaceGovernance
Placeholder. Discovery, one observed action and a policy decision.
A closer look at Conversational
Connect a source, ask a question, inspect why the answer was given. Native product screenshots will replace this schematic after a reviewed capture. The workflow is labelled illustrative.
Open the original material and see what supports the result. A cited source makes the answer easier to check.
This example is labelled illustrative. It is not live inference and not a measured correctness guarantee.
Illustrative walkthrough. A project review was first recorded as Tuesday, then corrected to Friday.
The Ask view shows Friday with a source link. The Sources view shows both notes. What changed lists them in order.
A research record you can examine
The published temporal-validity studies investigate obsolete facts and changing software histories. The conversational research evaluates selected context with local and hosted readers. Each result belongs to its stated task, model and protocol.

The primary indexes and source processing run on your device. Account services and selected bounded policy decisions use MemStrata services. A cloud reader or destination receives the content needed for the connection you choose. Credentials are stored in the operating-system credential vault. Customer content is not used for training unless the customer separately opts in.
On your device
Primary indexes, source processing and local evidence. Files you import stay in the product environment you install.
Named service calls
Account activation, a configured cloud reader, and applicable remote policy services. These do not disappear behind an absolute offline slogan.
Full product access for 180 days after activation. No subscription during the trial.
Detected choices are a suggestion only. A browser cannot reliably know your macOS version or whether Python is installed.
Python 3.10 or newer is required. On Windows, if Python is missing, install it from python.org/downloads/windows and open a new terminal.
Microsoft Store Python redirects LocalAppData writes. The Windows command follows the real environment path after venv so pip is not pointed at an empty folder.
