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.

Send almost any everyday document.

MonFile starts by detecting what arrived, then turns that file or batch into a short list of useful actions. Users do not need to know file extensions, compression settings, OCR tools, or conversion software.

Office documents DOCX, XLSX, PPTX, and everyday work files
PDF workflows Compress, merge, split, extract pages, and export images
Images and scans JPG, PNG, WEBP, receipts, forms, and photo batches
Text and CSV Plain text, tabular files, and simple extraction jobs
Voice instructions Tell MonFile what to do after sending the files
Multi-file batches Send several images or PDFs and ask for one output

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.

High-frequency document work, handled in chat.

MonFile starts with the tasks people ask for every day and expands into OCR, translation, summarization, and team workflows after the core conversion loop is reliable.

Word to PDF Turn office documents into shareable PDFs.
Images to PDF Bundle photos and scans into one clean file.
Compress PDF Reduce size before sending through chat.
Merge PDF Combine multiple PDFs from one conversation.
Split PDF Extract the pages you need.
Extract text Pull text from digital PDFs and scanned images.

Global file help for teams that live in chat.

The problem is not local to one country or one industry. Anywhere people exchange forms, scans, receipts, contracts, or reports over messaging apps, MonFile can remove the manual handoff.

Operations teams Convert invoices, application forms, statements, and signed scans directly from chat.
Field workers Turn mobile photos and voice notes into structured files without opening a desktop tool.
Finance and admin Compress PDFs, combine receipts, and extract text before forwarding documents.
Students and creators Bundle screenshots, class notes, forms, and slide decks into shareable formats.

Language should not decide who gets file help.

MonFile is designed for multilingual chat from day one. The file can be in one language, the instruction can be typed in another, and the user can also send a voice note.

Typed requests Users can ask naturally instead of choosing technical conversion options.
Voice notes Speech is transcribed and mapped to the active file batch.
Document text OCR and extraction workflows preserve the original language where possible.
Human fallback When the request is unclear, MonFile asks a short follow-up question in chat.

Private by default.

MonFile is designed for sensitive everyday documents. The AI layer understands instructions; deterministic workers perform the actual conversion.

Temporary files Files are stored only for processing and automatic cleanup.
No raw files to AI OpenRouter receives instructions, transcripts, and metadata by default.
Multilingual input Text and voice commands can be understood across languages.
Batch aware Images, PDFs, office files, and mixed uploads are handled as sessions.

Join the private beta.

We are opening MonFile to early users who regularly convert documents from chat. Telegram beta comes first, followed by WhatsApp.
