Alembic is a professional, private data-preparation workspace for turning messy source material into dependable training datasets and retrieval-ready collections. IMPORT REAL-WORLD DATA Open CSV, TSV, JSON, JSONL, SQLite, Markdown, HTML, plain text, code, or entire document folders. Alembic detects structure, encoding, delimiters, types, and import problems before processing begins. DESIGN A REPEATABLE PIPELINE Compose deterministic steps for normalization, null handling, type inference, exact and near-duplicate removal, quality filtering, token counting, semantic chunking, privacy scrubbing, decontamination, schema shaping, and dataset splitting. Disable, reorder, inspect, and replay every step. PREPARE TRAINING AND RAG DATA Shape clean records for Alpaca, OpenAI, Anthropic, ChatML, and DPO structures. Build reproducible splits, sentence-aware token-budgeted chunks, heading paths, metadata, real cl100k token counts, and embedding-ready JSONL. PRIVACY AND QUALITY CONTROLS Detect and redact emails, phone numbers, addresses, credentials, API keys, financial identifiers, and other sensitive patterns. Screen against evaluation sets, identify exact and fuzzy duplicates, and inspect quality metrics before export. LOCAL BY DEFAULT The deterministic pipeline works locally. Optional provider augmentation uses a provider you configure; credentials stay in Keychain and selected content goes directly to that provider. FREE AND PRO Importing, the complete deterministic pipeline, preview, dataset reports, and export are free forever. Alembic Pro is an optional auto-renewable subscription with monthly and annual choices and an eligible 7-day free trial. Pro unlocks LLM-assisted Q&A generation, quality scoring, rewriting, classification, and preference-pair creation. The current localized price and trial eligibility are always supplied by the App Store before purchase. Restore Purchases and Manage Subscription are available in Settings.

Verdict
The clearest difference is update cadence: OmniClassify at every 2 days against Alembic's monthly. On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. OmniClassify sells 3 in-app purchases, starting at $3.99 per 7 days and Alembic sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
OmniClassify ships an update every 2 days, Alembic monthly. The most recent releases landed on November 12, 2026 and November 13, 2026 respectively.
