Blabble — Communication, Reinvented

Take a closer look.

Communication is scattered. Context is lost.

Your messages live in various channels — separate apps, separate histories, seperate context. When you need AI help, you copy fragments into a chat box, lose context, and start over. Every time.

Blabble flips the model. Instead of bringing your conversations to the AI — Blabble brings the AI into your conversations, responsibly.

Sandboxed by Design

Blabble never modifies your original messages. All your data is copied into Blabble's sandbox and read-only at the source. The AI agent is fully guardrailed, and any outbound delivery (Agent Rules, Remote Agent replies) goes only to destinations you explicitly configure.

Bring Your Own LLM

Blabble lets you work with the LLMs you choose. Set the default models for different tasks such as summarizing, translating, spell checking, or full agent mode.

Rich Relevant Context

Blabble provides the AI agent with the most relevant context across time, framing the conversation and incorporating attachment content, voice transcripts, and text extracted from images.

Private by Architecture

Blabble doesn't send your data to its servers. Each conversation is isolated and boxed to only that conversation. If you choose a cloud-based LLM provider, only the conversation parts you're currently viewing are sent to that provider. If you select a local model, nothing leaves your device.

Much More Than A Chat Box.

A Real Agent, Not a Chat Box

Blabble's AI doesn't just answer questions. It's equipped with real tools to search through your conversation, read attachments, and reason across messages. It works with what's there, not just what you type.

Keyword & Semantic Search

The agent searches your conversation two ways: exact keyword matching for precision, and semantic search that understands meaning. Ask "when did we discuss the budget?" and it finds the right message, even if the word 'budget' was never used.

Multi-Step Reasoning

Unlike a one-shot chat box, Blabble's agent thinks in steps. It searches, reads what it finds, refines its understanding, and digs deeper, iterating until it has the full picture before answering.

Reads Every Attachment

PDFs, images, documents, even voice messages. The agent can read and understand them all. Drop a file into the conversation and ask questions about it, or let the agent pull context from attachments it finds during search.

Advanced Context.

Your Agent On The Go.

Remote Access

Send your Agent a message like "Draft a reply to John's last offer". It has full access to the context, attachments, and history, and sends your draft right back, just like that.

Agent Rules

Set rich Agent rules like "Summarize all messages from the last 24 hours". Your Agent delivers the result to the email address or iMessage handle you choose.

Project Management

Start a conversation with your Agent, set its context, and drop in files. It has access to your communications, can create documents, and helps you throughout the project.

Access Control

You stay in control of which sources your Agent can access, whether for rules, project conversations, or the Remote Agent.

Smart to Understand Everything. Scoped to What You Allow.

Blabble reads your messages but never modifies them. The AI agent can search, read, and reason over your conversations. When you enable Agent Rules or the Remote Agent, outbound messages and emails go only to destinations you have configured yourself. Blabble cannot send anywhere else, and every automated feature is disabled by default.
