Two Ways to Use Files
Attach to a chat — click the paperclip icon or drag-and-drop a file onto the chat input. ZeroTwo processes the file and responds in context of your message. Best for one-off analysis. Files Library at/files — every file you upload is automatically saved to your library. Browse, search, filter, and re-attach any past file to a new chat without uploading it again. Best for reference documents, templates, and data you use repeatedly.
What ZeroTwo Does with Your Files
The capability ZeroTwo applies depends on the file type:| File Category | What ZeroTwo Does |
|---|---|
| Documents (PDF, DOCX, PPTX, XLSX, etc.) | Full text extraction, Q&A, summarization, translation |
| Code (JS, TS, PY, GO, and more) | Review, explain, refactor, identify bugs, generate tests |
| Data (CSV, JSON, Parquet, etc.) | Analyze patterns, compute statistics, generate visualizations |
| Images (PNG, JPG, GIF, WEBP, etc.) | Vision analysis — describe content, OCR text extraction, visual Q&A |
| Audio (MP3, WAV, M4A, etc.) | Whisper transcription followed by discussion and summarization |
| Video (MP4, MOV, WEBM, etc.) | Frame extraction + vision analysis — describe scenes, find moments |
| Notebooks (IPYNB, Rmd) | Full cell and output reading — explain code, methodology, results |

Common Use Cases
Document Q&A
Upload a PDF, DOCX, or presentation and ask questions: “What are the key findings in section 3?” or “Summarize the executive summary.” ZeroTwo reads the full document and answers in context.
Code Review
Attach a code file and ask: “Review this for bugs,” “Explain what this function does,” or “Refactor this using modern patterns.” ZeroTwo reads the entire file, not just a snippet.
Data Analysis
Upload a CSV or JSON file and ask: “Which product category had the highest growth from Q1 to Q3?” or “Show me a summary of this dataset.” ZeroTwo reads the data structure and analyzes it.
Audio Transcription
Attach a meeting recording (MP3, WAV, M4A) and ask: “Transcribe this and list the action items.” Whisper handles the transcription automatically. Works in multiple languages.
Image Analysis
Upload a screenshot, photo, or chart image and ask: “What does this chart show?” or “Extract all the text from this screenshot.” Vision AI describes content and reads text (OCR).
Video Description
Attach an MP4 or MOV file and ask: “Describe what happens in this video” or “What steps does the presenter demonstrate?” ZeroTwo extracts frames and applies vision analysis.
Files Library
Every file you upload is automatically saved to your Files Library at/files. From there you can:
- Search files by name
- Filter by type (Documents, Images, Audio, Video, Code, Data)
- Sort by upload date or file size
- Re-attach any file to a new chat without re-uploading
- Download files back to your device
- Delete files you no longer need
Privacy
Your uploaded files are stored in per-account Supabase storage, encrypted at rest. Files are private to your account — no other user can access them. ZeroTwo does not use your uploaded files to train models. Files uploaded within a project are scoped to that project.Files Pages
