Supported File Types

ZeroTwo supports a broad range of file types across documents, code, data, media, and notebooks. The processing method depends on the file category — here is a complete breakdown.

​

Documents

ZeroTwo extracts full text and structure from all major document formats, enabling Q&A, summarization, translation, and data extraction. What you can ask:

• “Summarize the executive summary of this report.”
• “What are the main arguments in chapter 3?”
• “Extract all deadlines and owners from this contract.”
• “Compare these two proposal versions and highlight what changed.”
• “Translate this document from Spanish to English.”

​

Code Files

ZeroTwo reads the full source file with syntax awareness — it understands language structure, can follow function calls, identify patterns, and reason about logic. What you can ask:

• “Review this file for bugs and security vulnerabilities.”
• “Explain what each function does.”
• “Refactor this code to follow modern best practices.”
• “Write unit tests for the functions in this file.”
• “Convert this Python script to TypeScript.”
• “Add type annotations and docstrings throughout.”

​

Data Formats

Structured data files are parsed and made available for analysis, statistics, schema description, and visualization prompts. What you can ask:

• “What are the column names and data types in this dataset?”
• “Which product had the highest sales in Q3?”
• “Describe the schema of this JSON file.”
• “Find any rows with missing values.”
• “Show the revenue trend by month as a bar chart.”

​

Markup Files

Markup and stylesheet files are read as text with structural awareness — ZeroTwo understands HTML semantics, CSS selectors, Markdown formatting, and GraphQL schema syntax.

​

Images

Images are analyzed by ZeroTwo’s vision model, which can describe content, read text (OCR), identify objects, and answer specific visual questions. Supported extensions: .png, .jpg, .jpeg, .gif, .webp, .bmp, .tiff What you can ask:

• “What is in this image?”
• “Extract all the text from this screenshot.”
• “Describe the chart in this image and summarize the data shown.”
• “What does the error message in this screenshot say?”
• “Is there anything unusual or out of place in this photo?”
• “Identify all the UI elements in this wireframe.”

​

Audio

Audio files are automatically transcribed using Whisper (OpenAI’s speech recognition model). The transcript is then available for discussion, summarization, and analysis. Supported extensions: .mp3, .wav, .m4a, .aac, .ogg, .flac, .opus What you can ask:

• “Transcribe this meeting recording.”
• “Summarize the key decisions from this audio.”
• “Pull out all action items and who they were assigned to.”
• “What topics were discussed in this conversation?”

​

Video

Frames are extracted from the video at regular intervals, then ZeroTwo’s vision model analyzes each frame. This allows scene description, object identification, and visual Q&A across the video. Supported extensions: .mp4, .mov, .webm, .avi, .mkv What you can ask:

• “Describe what happens in this video, step by step.”
• “What products are shown in this advertisement?”
• “Identify the steps demonstrated in this tutorial video.”
• “At what point does the presenter show the dashboard?”

Maximum size: 200 MB (Pro+), 50 MB (Free plan)

​

Notebooks

Notebooks are read in full cell context — code cells, Markdown cells, and cell outputs (including printed results, dataframes, and errors) are all available for analysis. Supported formats: .ipynb (Jupyter Notebook), .Rmd (R Markdown) What you can ask:

• “Explain what this Jupyter notebook does, cell by cell.”
• “Review the code in this notebook for errors and inefficiencies.”
• “Summarize the findings from the output cells.”
• “Convert this notebook’s analysis steps into a clean Python script.”
• “What statistical method is being used in this R Markdown document?”
