From desktop file upload to mobile document capture

The initial requirement covered selecting a project, uploading several files, showing progress and returning the exact destination paths. The desktop tool put these actions in one place.

A batch can contain a document and its supporting images. The recipient needs the complete set, with a receipt identifying what arrived.

The server prepares each upload in a temporary staging directory. As file data arrives, it checks size limits and calculates a content hash, a fingerprint of the bytes received. It also validates file names and identifiers.

After writing the files, the server moves the whole batch into its final location. That move makes the complete directory available in one operation. If preparation fails, the server removes the partial staging data.

The upload receipt identifies the stored files and their destination paths. The recipient can use those paths to locate the batch for the next stage of the project.

The mobile app added document preparation to the workflow. Users can scan pages, choose photos or import files into a local workspace. The app creates previews and supports PDF preparation before upload.

A paper document can enter through the phone's scanner and be reviewed alongside related files. Users prepare the material on the device that captured it, then hand over the batch to the selected project.

The desktop requirement established the destination, upload progress and receipt. Mobile capture extended that workflow to the creation and review of the source documents.

The desktop service was delivered in July 2026, followed by an App Store release of the mobile app. This PitchAI tool covers capture, review and file handoff. The receiving project controls what happens to the documents next.
