#fact-checking

Stipple gives AI agents a full document-verification suite over one MCP server: forensic authenticity inspection (tampering, AI-generation signals, arithmetic reconciliation), document classification, universal field extraction (including checkboxes and tables), identity verification (Australian 100-point / AUSTRAC), document-pack completeness, PII detection & redaction, plus citation/reference verification and AI-text detection. Every result is honest coverage with evidence — a signal for review, never a black-box verdict. Stateless; documents are not stored.

Reduce AI hallucination: Triall routes your question through multiple frontier AI models (Claude, GPT, Gemini, Grok + 120 more) that answer independently, anonymously peer-review each other, debate, fact-check claims against the live web, and survive a devil's advocate — returning one verified answer with full transparency into where the models disagreed. Free tier, no signup.

Cited product-review verdicts synthesised from real user voices across Reddit, YouTube, HN, Trustpilot & more. Free remote MCP, no API key.

AIs confidently state outdated facts because of training cutoffs. Out to Lunch is a hand-curated daily briefing covering what they get wrong most: current world leaders, recent deaths, active conflicts, economic data, holidays, AI model releases, and specific wrong-to-right corrections. Two tools: get_world_briefing (json/compact/nano formats, per-section filtering) and submit_correction to report errors. Updated daily, human-reviewed.

Parallect is an MCP server that turns any AI assistant into a deep research powerhouse. Instead of relying on a single provider, it fans out your research queries across Perplexity, Gemini, OpenAI, Grok, and Anthropic in parallel -- then synthesizes the results into a single coherent report with extracted claims, cross-provider confidence scoring, deduplicated citations, and automatic conflict resolution. Manage research threads with follow-up questions, drill into individual claims with full evidence chains and source URLs, search across your findings by confidence level, and control spend with flexible budget tiers. One MCP, every major research model, one unified answer.
