What is Streamient?

Streamient, formerly Kumbukum, is an open-source memory layer for AI-native teams and MCP-compatible tools. It turns scattered company knowledge — notes, durable memories, URLs, stored email, Git repositories, decisions, and project context — into shared, editable memory that survives across sessions and clients. People can inspect, correct, search, export, and self-host the same records connected AI tools retrieve through MCP or API.

Your team's memory. Available to every connected AI.

Notes, memories, links, stored email, and code in one inspectable layer people can maintain and AI tools can retrieve.

Structured knowledge, plain text.

Meeting notes, specs, decisions, documentation — in one searchable place with tags and links. Editable from the web app or via Git sync. Plain Markdown, always.

Reusable context, not chat history.

Preferences, decisions, key facts — the things your AI should know before the first message. Capture them while you work or write them by hand, then retrieve the relevant context in a later session.

Links your AI can actually use.

Save URLs from anywhere — with their content, their relationships, and your notes attached. No more bookmark graveyards. Source material stays alive.

Email history becomes reusable context.

Store important email threads as searchable source material. Streamient keeps the message, metadata, relationships, and your notes available to every connected AI tool.

Streamient · The bigger picture

One team.
Five tools.
Fewer gaps.

Streamient turns notes, decisions, URLs, stored email, Git, and project context into shared, inspectable memory for people and connected AI tools. Around it, four focused products manage customer conversations, inbox work, digital assets, and product growth.

01 · Customer conversations

Give customer conversations a life beyond the thread.

Helpmonks keeps shared email, live chat, customer history, and team collaboration together. Important conversations can become searchable source material in Streamient, preserving the decisions and context future teammates and AI tools will need.

Meet Helpmonks
02 · The working inbox

Give every draft the context it needs.

Mailtwine prioritizes, summarizes, drafts, routes, and follows up across the inboxes your team already uses. When connected, it can use knowledge stored in Streamient to prepare grounded replies instead of starting from an empty prompt.

03 · The files

Connect durable knowledge to the files it explains.

Razuna keeps approved images, videos, and documents governed and searchable. Streamient preserves the decisions, notes, URLs, and relationships that explain why an asset exists, how it should be used, and what the team learned.

Meet Razuna
04 · The product loop

Keep product decisions attached to their evidence.

Managani brings feedback, roadmaps, changelogs, chat, tours, surveys, highlights, and tracking into one product-growth workspace. Streamient keeps the supporting research, conversations, and decisions reusable beyond one roadmap card.
