Drive opens Word, Excel, and PowerPoint files

Files that open where they live, and an assistant that can produce real documents rather than blocks of text.

A drive that only stores files is a filing cabinet with search. The useful version is one where the assistant can read what is in the files and write new ones that open correctly in the software everyone else uses.

Heyno Drive opens Word, Excel, and PowerPoint natively, and produces them with real structure.

Files as work, not storage

Every file in the drive is readable context. Ask a question that depends on a contract and the answer comes from the contract, with the clause cited, rather than from a summary written months ago.

Uploading a document is therefore closer to teaching than to archiving.

Documents are readable context, not opaque attachments.
Answers cite the clause or cell they came from.

Real document structure

A generated document is a real document: headings that are headings, tables that are tables, styles that survive being opened in Word. Text that merely looks formatted falls apart the moment someone edits it.

The same applies to spreadsheets, with formulas rather than pasted values, and to decks with actual slide structure.

“Turn these notes into a proposal with a scope table and a signature block.”

Editing in place

Files open in the browser and edit in place. Changes are versioned, and the assistant can describe what changed between two versions in words rather than as a diff.

Version differences are explained in language, not as raw diffs.

Where files come from

Files arrive from uploads, from email attachments, from meeting recaps, and from work the assistant produced. They land in one place with one permission model rather than in four systems with four.

Permissions

Drive permissions are workspace permissions. The assistant cannot read a file the person asking could not read, and it says so rather than answering from something adjacent.
