What Rexii creates

From request to finished work

See the simple flow: give Rexii a task, then get a file you can open, check and use.

01
Bring the task and context
Start with a question or add the files Rexii should work from.
02
Describe what you need
Tell Rexii what you want to produce, such as a report, presentation or spreadsheet.
03
Review a usable file
Open the result on your computer, check its sources or inputs, and edit or share it.

Rexii creates Word reports, PowerPoint decks and Excel workbooks, with sources or input records to help you review the result.

Local AI and privacy

Your files are processed on your machine

Rexii reads your documents and runs its AI model on your own computer. Here is exactly what stays local, and when the network is used.

Stays on your machine

Your files. The PDFs, Word documents, spreadsheets, CSVs and folders you give Rexii are read on your computer, and anything built from them is generated locally.
AI processing in Privacy mode. The language model runs on your machine, so your prompts and document text are processed locally.
Your voice in Privacy mode. Speech recognition runs on-device.
Everything Rexii makes. Generated documents, memory, history and the audit trail are stored in your home folder.

Uses the network, only for these

Web research you ask for. Search queries go out and public pages are read. When a request uses files you attached, Rexii asks before anything goes online.
Decks on public topics. Rexii may send public facts it has already gathered to a free cloud writer to polish the wording. Never used for anything built from your files.
Cloud mode, if you switch to it. Typed and spoken requests can go to cloud AI models for extra capability. Privacy mode keeps the model on your machine.
Accounts you connect. Gmail, Slack, Notion or your calendar, only when you use them.
Updates and crash reports. Update checks send version information only. Crash reports are opt-in.

Local-only lock

Turn it on and every cloud AI call is refused: chat, image reading and speech recognition all stay on your machine. Searches can carry only what you type; once a request uses your files, Rexii asks before anything goes online. Your IT team can lock it on.

See what left your computer

A built-in log lists every outbound request from the last 30 days: searches, page addresses and cloud calls, never the content of your files. Export it as a CSV for your IT team or a client.

Small local models, honest limits

The model Rexii runs on your machine is much smaller than cloud AI, and on some tasks it is less accurate, especially fast-changing facts such as upcoming events. That's why Rexii shows its sources, so you can check what it gives you before you send it.

Who it's for

For work too sensitive for the cloud

The most sensitive work is the work you most want help with.

Consultants, analysts, finance and legal

The client files you'd never paste into a chatbot. Build the report, the deck or the analysis from them without uploading anything.

Students and researchers

Literature reviews, reports and data analysis from your own papers and datasets. Private, and free to start.

Regulated teams

AI that stays on the device, a privacy lock IT controls, AI labels in every file and records you can export.

Rexii for organisations

Three seconds to master.

No interface to learn. No commands to memorize. If you can talk, you can use Rexii.

Say what you need

Press Right Option (Mac) or Right Ctrl (Windows) and talk normally. No special commands, no menus. Just tell Rexii what you want done.

It gets done instantly

Rexii figures out what you meant and does it. An email gets drafted. A doc gets created. A search runs.

You never leave what you're doing

No switching tabs. No copy-pasting between apps. The result shows up right where you're already working.

Try saying this

"Send Mike a follow-up. Mention the revised timeline and ask if Thursday works for a quick sync."

Dictation

Write at the speed of speech

We speak around 150 words a minute and type around 40. Hold your hotkey and talk: your words land on the page almost four times faster, with the ums cleaned up.
