Usable · Microsoft 365 add-in

Usable lives inside the apps you already work in.

It brings the assistant you already know into Word, Excel, PowerPoint and Outlook — drafting, explaining and reshaping content right where your work already is. Install it per app, grant access on your terms, and remove it just as easily.

How it works

Powerful help, private by design

You ask in plain language; the assistant helps with what's in front of you. When it needs to think, your request makes one encrypted round-trip to an AI — and is gone the moment it answers.

You & your document

Working in Word, Excel, PowerPoint or Outlook — nothing new to learn.

Usable assistant

Reads only what you point it at, then drafts and edits right in your document.

AI does the thinking

Handles your request in the moment — then instantly forgets it.

Your data stays yours. Your document and your chat history stay on your device — Usable keeps no copy.

Zero Data Retention — your prompts never stick around

Every request runs through zero-retention AI endpoints. Your prompts and the replies are processed in memory and discarded the instant the call finishes — never retained on our servers, never trained on.

  • Processed in memory

    Your prompt and its reply live only in volatile memory while the request runs — never written to disk by the model.

  • Discarded instantly

    Input and output are wiped the millisecond the API request concludes. Nothing lingers on the provider's servers.

  • Stays on your device

    Your conversation history is kept locally on your own device — never uploaded to or retained on Usable's servers.

  • Never trained on

    Your data is contractually opted out of all model training, fine-tuning, and human review.

  • ZDR on every model

    Claude, GPT-5.5 and Gemini all run through zero-retention endpoints — no manual setup, no exceptions.

  • Encrypted in transit

    Every request travels to the Usable gateway over TLS 1.2+, then on to a zero-retention provider.

Most AI tools keep your prompts anywhere from 30 days to 18 months. Usable keeps them for zero.
