Built for the way people already ask for file help.

MonFile replaces the technical friend in the middle. Users send documents, screenshots, scans, or batches of files and describe the outcome they want in natural language.

1

Send a file

Documents, PDFs, spreadsheets, slides, images, and scanned files arrive from chat.

2

Type, tap, or say what you need

Use buttons, text, or a voice note. MonFile understands the active file or batch.

3

Get the finished file back

The converted file is delivered back into the same conversation.

A chat-first workflow, not another upload portal.

The first beta focuses on Telegram, then WhatsApp, then LINE. Multiple uploads become a batch, voice notes become instructions, and unsupported video files are politely ignored.

1
Detect the upload

MonFile reads file type, size, and batch context before asking the next question.

2
Understand the instruction

Buttons, typed messages, and voice notes all map to the active file batch.

3
Return the result in chat

Users receive the finished document in the same conversation, with no portal account.
