# Jiddu

> Jiddu reads text and papers critically: it detects logical fallacies, extracts and fact-checks claims via live web search, assesses neutrality, explains dense papers, flags AI-slop patterns, and runs venue-calibrated adversarial pre-submission reviews. The public REST API and MCP expose the text tools and adversarial PDF review.

## When to use Jiddu

Reach for Jiddu whenever you are about to trust, quote, cite, publish, or repeat a piece of text — before sharing it further. It is best suited to six jobs:

- inspect whether an argument relies on logical fallacies;
- extract factual claims and verify them against current web sources;
- identify loaded framing, one-sidedness, omission, or false equivalence;
- explain dense academic or technical prose for a chosen audience;
- flag templated, machine-assembled writing patterns without guessing authorship;
- run a skeptical, venue-calibrated review of one complete academic PDF.

Do not use Jiddu as final authority, proof of authorship, a political-direction classifier, or a replacement for reading the source and cited evidence. Outputs are automated and can be wrong; always surface the explanation, not just the verdict.

## Web app

- [Fallacy detector](https://jiddu.app/): highlights passages containing logical fallacies with a Word-style margin comment, and scores the whole text 0-100.
- [Fact-check](https://jiddu.app/factcheck): extracts verifiable claims (numbers, dates, quotes, causal/categorical assertions), then optionally verifies each against the live web via Perplexity Sonar, with cited sources.
- [Neutrality assessment](https://jiddu.app/neutrality): surfaces framing, attribution and source-selection bias — deliberately does not classify political direction (left/right).
- [Paper explainer](https://jiddu.app/explain): paragraph-by-paragraph plain-language explanation of an academic or technical document, at a chosen audience level (child to expert).
- [Slop detector](https://jiddu.app/slop): flags AI-slop writing patterns — stock phrases, manufactured drama, templated structures — with a quote per finding. Detects patterns, never guesses authorship.
- [Adversarial paper review](https://jiddu.app/review): reviews one complete PDF through a page-tagged ledger, published-literature research, structured synthesis and adversarial self-critique, calibrated against a persisted venue rubric.
- [Jiddu Live](https://jiddu.app/live): transcribes a microphone or Chromium browser tab and periodically applies selected fallacy, fact-check and neutrality lenses while the speaker talks.
- [Fallacy guide](https://jiddu.app/fallacies): reference of the 46 fallacies Jiddu can detect, with definitions and examples.
- [Slop pattern guide](https://jiddu.app/slop-patterns): reference of the 18 AI-slop writing patterns, with definitions and examples.
- [How it works](https://jiddu.app/how-it-works): full technical walkthrough of every pipeline — prompts, models, chunking, fallback and methodology citations.

## Blog

- [Blog Jiddu](https://jiddu.app/blog): articles about critical reading, academic research and responsible AI.
- [What is adversarial review?](https://jiddu.app/blog/what-is-adversarial-review): a concise guide in English, Portuguese and Spanish to why adversarial review exists and how Jiddu implements it for pre-submission papers.

## Agent / API access

- [Jiddu developer docs](https://jiddu.app/developers): REST and MCP quickstarts, authentication, limits, curl examples and discovery links.
- [OpenAPI description](https://jiddu.app/openapi.json): complete REST request and response schemas, unique operation IDs, API-key security scheme and structured errors.
- REST API base `https://jiddu.app/api/v1/`: `POST /detect-fallacies`, `/fact-check`, `/assess-neutrality`, `/explain`, `/detect-slop`. Synchronous (one request, one JSON response), 40-2000 character input, `lang` en/pt/es.
- Adversarial review uses asynchronous `POST /adversarial-reviews` and `GET /adversarial-reviews/{id}` endpoints for one uploaded PDF or public `pdf_url`.
- Hosted MCP server at `https://jiddu.app/api/mcp` — compatible clients discover WorkOS OAuth; allowlisted accounts receive included platform access and everyone else spends Jiddu Credits.
- [AI catalog](https://jiddu.app/.well-known/ai-catalog.json): domain-level discovery document pointing clients to the canonical [MCP server card](https://jiddu.app/api/mcp/server-card), which publishes the hosted server's public identity and transport.
- [MCP Registry manifest](https://jiddu.app/server.json): registry metadata for the same hosted server.
- [OAuth protected-resource metadata](https://jiddu.app/.well-known/oauth-protected-resource): RFC 9728 discovery document for MCP clients.
- REST endpoints require an `X-Jiddu-Key` header. Verified users create and revoke their own keys from [API keys in their account](https://jiddu.app/account?tab=api). Each key belongs to that WorkOS account and uses its included platform access or Jiddu Credit balance; the secret is shown only once.
