Data Protection & Masking
Scan, detect, and redact personally identifiable information (PII), credentials, and financial metrics in your staging datasets. Apply character masking and data swaps to ensure compliance with HIPAA, GDPR, and SOC2.
- ✓ Swap names, emails and phone numbers
- ✓ Character obfuscation & redaction rules
- ✓ 100% local, secure in-browser anonymization
AI Prompt Sanitizer
Sanitize real customer PII, salaries, and secrets before sending to ChatGPT/Claude. Reverse de-mask in 1 click.
PII Anonymizer
Mask, redact, or replace sensitive data fields like names, emails, and phone numbers.
PII Detector
Scan and detect PII, financial credentials, and national identifiers within your datasets.
Data Masking
Apply character-masking algorithms (e.g. *******) to block readability of sensitive attributes.
Base64 Encoder
Convert text, code, or UTF-8 strings into standard or URL-safe Base64.
Base64 Decoder
Decode Base64 payloads and data blocks back into readable UTF-8 text strings.
URL Encoder
Percent-encode URL parameters, query strings, and special characters safely.
URL Decoder
Decode percent-encoded URL query parameters back into plain text.
File Format Transformation
Translate schemas and interchange structures between JSON, CSV, Excel, XML, and YAML formats. Format or clean records, encode base64 payloads, and validate syntaxes client-side with zero data server storage.
- ✓ Bidirectional converters for CSV/JSON/Excel
- ✓ AI-assisted dataset cleaner and deduplicator
- ✓ XML-to-JSON and Base64 URL escaper codecs

CSV to JSON
Convert CSV tabular data into structured JSON array string format.
JSON to CSV
Flatten complex hierarchical JSON arrays into clean CSV spreadsheets.
Excel to CSV
Extract workbook sheets from Excel (.xls/.xlsx) files to flat CSV tables.
CSV to Excel
Convert flat CSV records into formatted Microsoft Excel (.xlsx) workbooks.
JSON to XML
Convert JSON arrays and object structures into clean formatted XML tags.
XML to JSON
Translate XML elements and attributes into structured JSON objects.
CSV Cleaner
AI-powered cleaner that detects and resolves duplicates, null values, and formatting issues.
JSON Formatter
Format, validate, prettify, or minify JSON structures with line-by-line syntax error parsing.

See How Much You Save with Sylvaera
Calculate the exact cost of generating synthetic test data and AI fine-tuning datasets in-house vs using Sylvaera's automated AWS Bedrock LLM engine.
Adjust Your Requirements
Multi-turn instruction pairs, DPO preference pairs, and RAG evaluation test suites.
Our pricing is based directly on the actual costs of running Anthropic Claude Sonnet 5.5 compute ($2/MTok input, $10/MTok output), with an honest and fair margin to support high-speed AWS Bedrock infrastructure and zero-data-logging privacy guarantees.
We strictly enforce a Zero-Data-Logging privacy guarantee: your uploaded schemas, evaluation test cases, and agent responses are never stored permanently, never transmitted to unauthorized parties, and never used to train artificial intelligence models.

Frequently asked questions
Is Sylvaera free to start?
Yes! Sylvaera provides 10 free full-featured invocations across all AI and relational tools with zero credit card required. All client-side file conversions (Excel, CSV, JSON, XML) and Base64/URL utilities are 100% free and unlimited forever. For production-scale generation (up to 1M Anthropic Claude Sonnet 5.5 LLM tokens and bulk exports), upgrade anytime to Developer Pro for just ₹799 ($9)/month.
How does Sylvaera compare to raw OpenAI or Claude API keys?
With raw API keys, you pay for both input and output tokens, plus spend 8–15 engineering hours writing Python scripts, handling JSON format errors, and resolving foreign-key relational dependencies. Sylvaera gives you 1 Million Anthropic Claude Sonnet 5.5 LLM tokens with pre-built relational integrity, mock APIs, and 1-click JSONL/SQL exports for just $9 (₹799)/mo—saving 95%+ in engineering costs.
What does PII anonymization do?
Personally identifiable information (PII) anonymization detects attributes like names, emails, national IDs, and credit cards. It masks or replaces them with synthetic fakes to preserve privacy before you share data with external teams or LLMs.
Can I convert Excel spreadsheet workbooks?
Yes. The format converter extracts specific sheet tabs from Excel `.xls`/`.xlsx` files and converts them into flat CSV or JSON structures in milliseconds, completely in your browser.
How is my data security and privacy managed?
Sylvaera prioritizes client-side security and zero data retention. Conversions, formatting, and codecs run entirely inside your browser. AI requests sent to AWS Bedrock LLM are ephemeral and are never stored or used for model training.
Can I cancel or upgrade my subscription anytime?
Yes. There are no lock-in contracts. You can upgrade, downgrade, or cancel your subscription at any time directly through your dashboard with instantaneous fulfillment via Razorpay.
