Workflow

① Upload

Click "Upload" in the navigation bar and select your document.

File size and character limits depend on your plan. Text that exceeds the per-file character limit is truncated (not left unredacted).

Uploaded files are stored in AWS S3 with KMS encryption and automatically scanned for viruses by ClamAV.

② Anonymize

After uploading, the AI automatically scans your document and detects the following types of personal information:

• Email addresses
• Phone numbers
• Social Security Numbers (SSN) and national IDs
• Dates (birth dates, contract dates, etc.)
• Names, addresses, and other personally identifiable information

Detected entities are replaced with placeholders like [EMAIL_REDACTED] and [PHONE_REDACTED]. Review the results and use the chat interface to request additional redactions or exceptions.

If the metadata-stripping module is enabled for your workflow, the pipeline can also remove author, revision history, and similar document metadata.

③ Chat

The chat interface lets you refine anonymization results using natural language. For example:

• "Also redact company names"
• "Keep the dates visible"
• "Remove the address on page 3"

The AI understands context and updates results based on your instructions. Iterate as many times as needed until you are satisfied.

Chat interactions consume credits from your balance. Credit usage is calculated based on the AI model's token consumption.

④ Audit

The Audit page provides a complete record of all actions performed on your documents:

• Upload timestamps and file details
• Each anonymization pipeline step and its outcome
• Document view and download history

Pipeline processing audit records are secured with a SHA-256 hash chain, making tampering detectable. Use this for compliance audits and internal controls.

Credits & Billing

Tokumeika uses a two-part pricing model: a monthly plan (which sets your file and size limits) and AI credits (which pay for chat usage).

Plan Limits

New accounts start on the Free plan with 3 files per month, 2 MB max file size, and 50,000 characters per file. Upgrade to a paid plan for higher limits and monthly credits.

Security & Privacy

• Encryption — Uploaded files are stored in AWS S3 with KMS (Key Management Service) encryption at rest.
• Virus Scanning — Every uploaded file is automatically scanned by ClamAV before processing.
• Tamper-Proof Audit — Pipeline processing audit records are secured in a SHA-256 hash chain, making tampering detectable.
• Access Logging — Sensitive document text views, downloads, chat attachments, and org audit views are logged with user, timestamp, and IP address.
• Encrypted Transit — All communication is encrypted via HTTPS.

The Max plan includes compliance-readiness features designed to support HIPAA, SOC 2, and GDPR workflows.

FAQ

What file formats are supported?

PDF, DOCX, PPTX, XLSX, HTML, CSV, JSON, XML, EPUB, and TXT files. Scanned-image-only PDFs and legacy .doc/.ppt/.xls files are not supported.

What happens if my file exceeds the character limit?

Text beyond the limit is truncated. It is not left unredacted — it is excluded from processing entirely.

When are credits consumed?

Credits are only consumed when you use the AI chat. File uploads and automatic anonymization do not cost credits.

What does the Free plan include?

All new accounts start on the Free plan — 3 files per month, 2 MB max file size, and 50,000 characters per file. No credit card required and no time limit. Upgrade to a paid plan for higher limits and monthly credits.

Can I upgrade or downgrade my plan?

Yes, you can change plans at any time. Upgrades are prorated for the remaining billing period.
