Unabyss

Unabyss is a shared context layer for AI tools. According to its official website, after connecting more than 20 sources such as email, Slack and Notion, it structures them into a real-time context, which is then provided to Claude, ChatGPT and other applications via MCP, covering scenarios such as weekly report writing, multi-agent collaboration and multi-client isolation.

What is Unabyss?

The positioning of Unabyss's official website is a universal context layer for all AI tools, with the slogan "Never Re-Explain Yourself to AI Again". The official website explains the difference between it and built-in memories like ChatGPT Memory and Claude Memory directly on the comparison page: built-in memories only work within the tool that generated them, and handwritten context files are frozen from the moment they are written. Unabyss connects your real sources and keeps them synchronized, then tags them by topic, sensitivity and source, enabling each tool to access the same set of context through MCP.

Who is it for?

Independent developers and founders who switch between multiple AI tools every day and have to repeatedly explain the same background
Engineering teams that hand over repository management to coding agents and need the agents to be aware of past decisions and coding conventions
Agency companies that serve multiple clients simultaneously and must prevent context mixing
Sales and marketing roles who need to unify pipelines, customer information, and meeting records to automatically generate follow-ups
Teams that have built their own MCP memory solutions and want to save on maintenance costs

Key features

Connect once, use everywhere

The official website states that it can connect to more than twenty sources including Slack, Gmail, Notion, calendars, GitHub, and Linear, and the page shows that users have saved more than one million memory sources.

Structured, Not Flat

Extracted content is organized into a real-time context. The official website states that it is tagged by topic, sensitivity, and source, and only the relevant parts are provided to the model instead of dumping the entire package.

Distributed via MCP

The official website states that over ten AI tools including Claude, ChatGPT, and Cursor all work based on the same context; it is also the official connector in the Claude directory and can be connected in one step.

Differences from Memory and Context Files

The official comparison page lists three key points — it covers every tool you use, connects to real sources so it’s never an out-of-date snapshot, and is fully owned by you, exportable, and portable when switching models.

Team and Multi-Client Isolation

Offers Teams and Company Brain; the official website states that in agency scenarios, each client's context can be clearly separated, and responses are only based on the corresponding account.

How to use Unabyss

Start with low-sensitivity sources for testing: Generate a weekly report using your schedule and public documents to confirm that the context is indeed being called, then connect your email and meeting records.
Clarify authorization scope: Before connecting email, Slack, and cloud drives, clarify what content is accessed and how long it will be retained.
for team scenarios, first agree on which customers' contexts can be shared.
The official website states that context is tagged by sensitivity, with a `confidential` label included as an example.
For confidential projects, first confirm that the labeling and isolation are actually effective before scaling up.
Keep compliance in mind: The footer of the official website states that SOC 2 Type II is still in progress.
Before enterprise procurement, check the progress and data processing clauses.
Use up the 7-day free trial first before making a decision: Every official plan comes with a trial.
The Pro plan is limited to 3 agents and 20 accounts, and the team plan requires a minimum of 3 seats.
Estimate the cost based on the actual number of seats.
