# askCPL

> askCPL is a forensic verification layer for digital content. We help writers, educators, publishers, and platforms detect AI-generated text using a 10-model ensemble, fact-check claims against live sources, and register original work to an immutable Content Provenance Ledger (CPL) with cryptographic proof anchored to Base L2.

askCPL combines a 10-tool AI workspace with the Content Provenance Ledger — a cryptographic notary for digital content using SHA-256 fingerprints, Merkle chains, and (planned) on-chain anchoring to Base L2. We never store raw content; only hashes and statistical fingerprints. Reports are explainable: every AI-detection verdict ships with sentence-level reasoning and a per-model breakdown, never a black-box yes/no.

## What askCPL is for

- **Writers & students** — confirm your own writing reads as human before submitting; humanize over-edited drafts.
- **Educators** — get a defensible score with reasoning, not a one-bit verdict you can't defend in a meeting.
- **Publishers & newsrooms** — vet inbound copy for AI generation and unverified claims before publishing.
- **Creators & researchers** — timestamp original work to the CPL so authorship is provable later.
- **Developers** — integrate detection + provenance via the REST API.

## Pricing

- **Free** — 2,500 words/day across all tools. One free trial analysis with no signup.
- **Monthly — $9.99/mo** — unlimited usage on every AI tool, full CPL access, no watermarks.
- **Annual — $79.99/yr** — same as Monthly, ~33% saving. Cancel anytime.

## How AI detection works (short version)

We run each submission through up to ten independent models (a mix of perplexity/burstiness statistical detectors, transformer-based classifiers, and stylometric analyzers). Each model returns its own AI probability; we report the ensemble consensus, the agreement level, and the individual model votes. Sentence-level scoring highlights the specific passages driving the verdict. We never claim absolute certainty — the platform is a forensic aid, not an arbiter.

## How the Content Provenance Ledger works (short version)

When you register content, we compute a SHA-256 hash plus a statistical fingerprint and append it to a Merkle chain. Batches of Merkle roots are (planned) anchored on Base L2 for tamper-evident timestamping. Verifiers can later prove a piece of content existed in a given form at a given time without us ever storing the content itself.
