What decides a specification's quality sits outside the model

Unfiled invention disclosures are not used for training
Inventors' contact details and ID numbers are masked on your computer before anything is sent. Disclosures and drawings stay locked in Vault.
The AI Firewall now runs on your device
Before your question even reaches an AI, personal details are de-identified right on your computer. The AI never sees them, and the details are filled back in when the answer comes back.
Your documents, safe in Vault
Templates and documents live in Vault, your cloud storage, and only come out for the work that needs them.

Answers to the five questions we hear most.
What is Redrob?
An AI agent for people whose work ends in a document, like lawyers, accountants, investors and doctors. It wraps the same AI model in skills for your field, your firm's templates and a workspace built for the job, so you get work a senior can review as is. Start on the web, then finish in your firm's format in the desktop app.
How does AI Firewall work?
Before your question reaches an AI, the desktop app swaps personal details for stand-ins like "Email 1" on your computer, then fills them back in when the answer arrives. Standard hides emails, phone numbers, resident registration numbers and card numbers. High also finds names of people, companies and places (it can miss some). Strict also turns voice off.
If the model is the same, why is the work different?
Because results depend a lot on how the model is run, not just on the model. Public benchmarks show the same model scoring higher in a tooled setup like a desktop app or a coding agent app. In Redrob's internal evaluation, compared with web chat, task-built skills made work about 27% better, and adding two or three of your firm's own templates made it about 48% better.
Do I need to know how to code?
Not at all. Type what you need in plain words, and Redrob Code does the developer-style work behind the desktop app: reading files, building the document and checking the result. No commands, no setup.
How much does it cost?
Free is free, Plus is $10 a month, Pro is $25 a month and Team is $30 per seat a month. On any plan you can top up credit from $5. See the pricing page for the details.
