🔐
1. Anonymous Access, Randomization & Blinding
Run assessments without requiring participants to provide names or other direct identifiers to BlitzTrials. Researchers remain responsible for deciding whether records stay anonymous or are linked within their own environment.
Participant IDs, Passcodes & Nicknames
Generate participant ID and passcode tickets without collecting direct participant identity in BlitzTrials, or allow nickname-based participation when ticket authentication is not required.
Researcher-Defined Groups & Blinding
Configure study groups and randomized assignment. Study administrators can keep participant identity and allocation information separate from researcher-facing records to support single- or double-blind study workflows where the study protocol requires it.
Participant-Specific Study Variables
Generate study-specific values or variables and attach them to participant tickets for dynamic use within assessment questions.
🧩
2. Building-Block Architecture
Build studies from reusable components instead of starting from scratch. Question banks, consent forms, certificates, participant tickets, branding, and other configured assets can be reused across multiple deployments.
Reusable Modules
Edit and recombine supported study components according to the needs of each research protocol.
Researcher-Defined Smart Routing & Quotas
Researchers define conditional routing and quota rules using responses, scores, sub-scores, or other study criteria, and BlitzTrials executes those configured rules during the assessment.
🧠
3. AI-Assisted Formatting & Configurable Scoring
BlitzTrials combines AI-assisted question formatting with researcher-configured timing, scoring, and routing tools.
AI-Powered Smart Parser
Copy source text from Word or PDF documents and use the integrated Gemini AI assistant to help clean and convert it into BlitzTrials parser syntax. Researchers can review and edit generated content before deployment.
Precision Time Tracking
The assessment engine records total assessment duration and time spent on individual questions for supported workflows.
Complex Scoring Matrices
Configure weighted responses, sub-scores, Visual Analog Scales, custom scoring matrices, and negative marking according to the selected research instrument or study protocol.
🏛️
4. Digital Workflows & Institutional Customization
Configure participant-facing study presentation, consent workflows, certificates, and administrative history without claiming regulatory approval on behalf of the study.
Digital Consent & Certificates
Deploy participant information and digital consent workflows before assessment access, and generate certificates using researcher-defined completion or passing criteria.
Custom Branding Suite
Configure supported participant-facing pages with institutional logos and study branding.
Audit Trail & Asset History
Review supported workspace activity and historical records of study assets, including recorded creation, modification, and decommissioning events.
📄
5. Local PDF Editor
Prepare research, administrative, consent, reporting, and supporting documents directly in the browser using the BlitzTrials PDF workspace.
Edit, Organize & Combine Documents
Open and merge PDFs or images, add or replace pages, reorder thumbnails, rotate, duplicate, crop, resize, extract content into a new working copy, and prepare a final document without modifying the original source file.
Text, Images, Signatures, Stamps & Markup
Add text, images, signatures or chops, stamps, highlights, paint/whiteout markup, and common form entries. Undo and redo support helps correct routine edits.
Review Comments
Place review comments, reply to discussions, resolve or reopen comments, drag comment pins, and draw non-printing review boxes around the area being discussed. These review markers remain a BlitzTrials-specific review layer and are not printed as part of the PDF page.
Find, Zoom & Mobile Navigation
Search searchable PDF text, move between matches, use Fit Page / Fit Width / Fit Height, and navigate enlarged pages with mouse, trackpad, or touchscreen controls.
Save, Print & Advanced Export Controls
Save a new PDF copy, print the current edited document, or use supported export options such as compression, password protection, redaction flattening, headers, footers, and page numbering.
Public access: The PDF Editor can be opened without a separate tools-page login. Non-member or non-Premium saved PDF exports retain the BlitzTrials watermark, while eligible Premium access removes it.

6. Local Image Editor
A lightweight companion workspace for preparing images before they are inserted into research documents, presentations, reports, forms, certificates, or the PDF Editor.
Fast Browser-Based Image Preparation
Open an image and perform common everyday editing without first moving the file into a full professional graphics application.
Crop & Resize for Research Workflows
Prepare figures, screenshots, scanned supporting material, signatures, chops, stamps, and other visual assets at a suitable size or framing before placing them into research documents.
Useful Alongside the PDF Editor
Prepare an image first, then insert the result into a PDF while keeping routine image and document work within the BlitzTrials Tools workspace.
Touch-Friendly Viewing & Navigation
The image workspace supports desktop and touchscreen use, including practical zooming and navigation for images larger than the available screen area.
Designed for everyday use: The Image Editor focuses on practical preparation tasks needed around research documents and supporting visual materials.

The BlitzTrials Edge
BlitzTrials separates participant-access credentials, research responses, optional participant-linkage information, and researcher-defined study rules so research teams can configure privacy, randomization, blinding, and data workflows according to their own protocol.
