v2.0.0 - AI Capability Reference

AI Capability Reference v2.0.0

This release is the real product reframe.

What started as a plan-by-plan feature tracker is now a capability-first, ontology-driven reference for understanding what today’s AI tools can actually do, where they work, what they cost, and what constraints apply.

What’s new in v2

• Capabilities are now the front door
  The homepage is no longer organized around vendor feature branding first. It starts from plain-English capabilities people actually care about.

• Detailed availability is still here
  The feature-first view remains available for plan, surface, and entitlement lookup.

• A new constraints view
  Access, limits, platform caveats, and gating now have their own dedicated view.

• A real shared data model under the site
  The repo now includes first-class records for capabilities, providers, products, implementations, model access, and evidence.

• Broader and cleaner coverage
  Coverage expanded across ChatGPT, Claude, Gemini, Copilot, Grok, Perplexity, and open/self-hosted model ecosystems.

• Ontology-first repo direction
  New design docs, migration strategy, validation tooling, and evidence sync workflows now support the project as a maintained reference system, not just a static tracker.

• Cross-platform skills
  The repo now includes reusable skills and bundle tooling for Claude, Perplexity, and Codex workflows.

Why this is v2.0.0

Because this is not just a UI refresh.

It changes the project’s:

• core mental model
• public information architecture
• data model
• maintenance workflow
• long-term roadmap

The old question was:

• “What features does this vendor say it has?”

The new question is:

• “What can this AI actually do for me, on my plan, on my surface, with these constraints?”

That is a real version boundary.

Also in this release

• new hero and social preview assets
• improved About page and README
• better provider filtering and UI polish
• fixed theme, anchor, spacing, and layout issues
• resolved large batches of verification issues
• refreshed roadmap around ontology, capability-first UX, and future agent-readable exports
• hardened skill-source hygiene and documented skill-provenance as a companion dependency

Thanks

Built with human review and multi-agent collaboration across Claude, Codex, Gemini, and Perplexity-assisted research workflows.

Automated verification system

Feature data is kept current by a multi-model verification pipeline:

• Multi-model cascade — queries Gemini, Perplexity, Grok, and Claude in parallel
• • Bias prevention — skips same-provider models (won't ask Gemini about Google features)
• • Consensus required — 3 models must agree before flagging a change
• • Auto-changelog — confirmed changes logged to each feature's record
• • Human review gate — creates issues/PRs, never auto-merges

# Run verification
node scripts/verify-features.js

# Check a single platform
node scripts/verify-features.js --platform claude

# Stale-only check (>30 days)
node scripts/verify-features.js --stale-only
