In private development
Keep your AI projects on solid ground.
Black Datum keeps the facts of your project — its goals, rules, decisions and where things stand — reliable across every ChatGPT conversation. ChatGPT can suggest changes. You decide what becomes part of the record.
Why it matters
Conversations forget
Long projects outgrow a single chat. Important details from earlier conversations are easy to lose.
Details drift
An assistant can quietly restate an earlier decision differently. Small changes add up until nobody is sure which version is right.
One trusted record
Black Datum keeps one approved version of your project's information and gives it to ChatGPT each time you send a message in a connected chat.
How it works
Choose a project for your chat
Click the Black Datum button in your browser while you are in ChatGPT and pick the project this conversation is about.
Chat normally
Each message you send in that chat includes your project's current, approved information, so ChatGPT works from the same facts every time.
You approve what changes
When ChatGPT suggests updating the project, Black Datum follows your approval settings: changes you want to check wait for you to approve, edit or reject them, and you can undo a saved change.
You stay in control
Your approval settings
Choose which kinds of changes need your approval — for everything, by category, or for individual records.
ChatGPT cannot approve itself
Suggestions from ChatGPT never change their own approval rules. Only you can.
Your own Google Drive
Suggested changes travel through report files that Black Datum creates in your Google Drive. It can see only the files it creates there.
Availability
Black Datum is in private development and is used by a small number of invited people. It is not yet available to the public and is not accepting sign-ups or payments. It currently needs a Windows computer, a Chromium-based browser such as Brave, and a ChatGPT account.
