Meta AI has gradually expanded its ability to accept uploaded files and read document content across selected product surfaces, moving beyond pure conversational use toward lightweight document interaction.
These capabilities are not uniformly available across Meta’s ecosystem, and their behavior differs significantly depending on whether Meta AI is accessed via the web, mobile interfaces, or messaging platforms.
Here we share how Meta AI handles file uploads in practice, which formats are supported, what analysis is possible, and where the current limitations remain as the system evolves into late 2025 and early 2026.

File upload support exists primarily on Meta AI web and is not universal across Meta platforms.
Meta AI’s most complete file upload and reading features are available through the meta.ai web interface, where selected users can attach files directly into a conversation.
This capability is still rolling out progressively and may not appear on all accounts or in all regions.
On messaging platforms such as WhatsApp, Messenger, Instagram, and Facebook, file sharing is possible, but structured file analysis by Meta AI remains limited or unavailable.
In those environments, Meta AI typically reacts to shared links, images, or attachments with contextual suggestions rather than deep document parsing.

Meta AI file upload availability by platform
Platform | Direct file upload | Document analysis |
Meta AI web (meta.ai) | Yes (select users) | Yes |
Limited | No | |
Messenger | Limited | No |
No | Image-focused only | |
No | Image-focused only |

Supported file formats focus on common documents and small datasets.
When file upload is enabled, Meta AI supports a narrow but practical range of formats.
PDF documents, plain text files, and basic Word documents are generally parsed correctly when they contain selectable text.
Spreadsheet support exists for small CSV and XLSX files, with performance degrading as file size or complexity increases.
Images containing readable text can also be uploaded, relying on optical character recognition rather than native document parsing.

Supported file types and practical limits
File type | Support level | Notes |
Yes | Best for text-based layouts | |
TXT | Yes | Clean parsing |
DOCX | Yes | Simple formatting only |
CSV | Yes | Small datasets |
XLSX | Partial | Limited rows and columns |
Images | Yes | OCR-based text extraction |

Document reading is optimized for summarization and Q&A rather than deep analysis.
Meta AI reads uploaded files to provide high-level summaries, answer direct questions, and extract basic information.
It performs best with short to medium-length documents that have clear structure and minimal formatting complexity.
Long reports, scanned PDFs, or documents with dense tables may return partial or incomplete results.
The system does not execute formulas, validate calculations, or perform multi-step data transformations.
··········
··········
Spreadsheet handling remains lightweight and conversational.
For spreadsheet uploads, Meta AI treats tabular data as conversational input rather than as an analytical workspace.
It can describe column meaning, summarize trends at a high level, and answer simple questions about values.
Advanced operations such as pivot tables, joins, forecasting, or formula debugging are not supported.
Files exceeding roughly a few thousand rows or tens of columns may fail to parse reliably.
··········
··········
All file analysis is session-bound with no long-term memory.
Uploaded files are processed only within the active conversation session.
Once the session ends, Meta AI does not retain awareness of previously uploaded documents.
There is no project-level memory, file indexing, or persistent document library.
Each upload must be reattached if the conversation context resets.

Memory behavior for uploaded files
Aspect | Behavior |
Cross-session recall | No |
File persistence | No |
Context duration | Active session only |
Document indexing | Not supported |
··········
··········
Privacy handling emphasizes ephemeral processing rather than storage.
Meta AI processes uploaded files temporarily to generate responses.
Public documentation emphasizes that files are not stored as reusable assets across sessions.
Data may be retained briefly for safety, abuse prevention, or system diagnostics in accordance with Meta’s broader AI policies.
There is no indication of user-accessible controls for file-level retention or deletion beyond session termination.
··········
··········
Current limitations define Meta AI as a lightweight document assistant.
Meta AI does not support automation pipelines, retrieval-augmented generation, or API-driven file ingestion.
There is no native integration with cloud storage services or enterprise document systems.
Advanced workflows involving structured data processing or large document collections are outside its scope.
The system is best used for quick reading, summarization, and conversational clarification rather than formal analysis.
··········
··········
Meta AI file reading fits casual and social workflows rather than enterprise use cases.
Meta AI’s file upload features align with its broader positioning as a conversational assistant embedded in social platforms.
The emphasis is on speed, accessibility, and convenience rather than depth or precision.
For users needing fast summaries or explanations of small documents, the feature is effective.
For complex document intelligence or spreadsheet analysis, more specialized AI platforms remain better suited.
