AI on a leash
Smarter use of the LLM you already use.
Take a closer look.
Copy-paste is dead. So is giving AI the keys.
Copy-pasting context piece by piece is a tax on your day. Letting an AI roam free across your messages, mail, and files is a tax on your privacy. Most apps pick one of those. Both are wrong.
Blabble does neither. Your messages stay where they are. The LLM only sees what you point it at. You stay in the driver's seat from start to send.
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. Switch between Apple Intelligence, OpenAI, Anthropic, Gemini, or local models whenever you want. No lock-in, no provider handcuffs.
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. You pick what the agent sees. As your picks evolve, the context evolves with them. No stale snippets, no manual re-paste.
Private by Architecture
Blabble keeps your data on your device. When you're inside a user conversation, each agent conversation is boxed to just that one: only the messages you're currently viewing are ever sent to a cloud LLM. Standalone Agent Conversations, Agent Rules, and the Remote Agent have broader access, but only across the sources you explicitly grant them. If you select a local model, nothing leaves your device.
Don't Burn A Data Centre To Spell-Check
Local models on your Mac handle simple work like summaries, spell checks, translations. No round-trip to a server farm. No compute you didn't need. No water cooled half a world away for a typo. Better for your privacy. Better for the planet. Cheaper for you.
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
Spin up a project, set its context, drop in files. The Agent only sees what you hand it. Hand-pick the conversations, hand-pick the folders, hand-pick the model. It builds, edits, and delivers, on the slice you defined.
Access Control
You stay in control of which sources your Agent can access, whether for rules, project conversations, or the Remote Agent.
*Optional: if you already have a ChatGPT Plus or Pro subscription, you can sign in with it through OpenAI's Codex authentication and use that quota inside Blabble. It's one of many providers Blabble supports, not a requirement. Usage stays subject to OpenAI's plan limits and terms, which may change at any time, and OpenAI may revoke or restrict third-party app access without notice. You can disconnect Blabble at any time from your OpenAI connected-apps settings.
