# AI Tool Watch

> What can this AI actually do?

A plain-English reference for AI capabilities, plans, constraints, and implementations across hosted consumer AI products from providers with roughly 1% or greater public market share (ChatGPT, Claude, Gemini, Copilot, Grok, Perplexity, Meta AI).

Maintained by Snap Synapse. Every claim carries its primary source and last-verified date.

## What this site covers

- 18 capabilities (e.g., Search the Web, Generate Images, Write and Edit Code)
- 87 implementations across 7 subscription AI products
- Plan-level availability (which subscription tier unlocks what)
- Surface availability (web, desktop, mobile, terminal, API)
- Gating (free, paid, limited)
- Evidence with sources and changelog for every claim

## Archived (frozen 2026-10-11, not refreshed)

Self-hosted runtimes (3) and open-model access records (11) were frozen on 2026-10-11 when scope narrowed to hosted products and maintenance was slimmed. They keep their last-verified dates and may be out of date.

### Data contract

- IDs are stable and safe to use as foreign keys
- Every record includes `verified` and `checked` dates for freshness
- File paths under /api/v1/ are stable within the version
- New fields may be added; existing fields will not be removed within v1

### Usage guidance

- Always include the `verified` date when citing data — the AI landscape changes weekly
- Respect gating and constraints — "available" does not mean "available to everyone"
- Don't strip caveats from talking points — they contain important context about restrictions
- Cache for up to 24 hours; don't poll more than once per hour
