See what an agent can do with Grok before you ever sign up. Pick a story: recorded sessions replay real probe-harness transcripts; commands tagged live-capable can re-run against the real endpoint from our edge, right now (▶ run live — the exact same request, live and recorded lines always labeled); sandboxed self-drive sessions are designed and gated (docs/TRY-IT.md).

Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 42 stories with headroom

What would move Grok’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.

  1. Automation depth — how much of the product can run unattendedDefine rules that trigger actions automatically on events

    nonemoves PA Scoreimpact 30

    Grok's docs describe connectors, tool integrations, and a persistent 'Grok Bot' cloud agent, but nothing describes user-defined rules that trigger actions automatically on external events (e.g., webhooks, triggers, if-this-then-that automations, or scheduled event listeners).

  2. Agents tasks — stories about agents tasks in this arenaHave the assistant operate a web browser on my behalf to research and complete tasks on websites

    nonemoves PA Scoreimpact 30

    The evidence shows connectors for APIs, email, calendar, Salesforce, and a vague 'Grok Bot' cloud computer teammate, but nothing documents Grok actually driving a web browser to navigate sites or complete tasks (no browsing/computer-use agent feature is described).

  3. Files analysis — stories about files analysis in this arenaHave the assistant write and run code on my data to produce charts, computed answers, and downloadable files

    nonemoves PA Scoreimpact 30

    The evidence describes Grok's coding assistant (Grok Build), connectors for email/calendar/files, image/video generation, and multi-agent research, but nothing documents a code-interpreter style capability where Grok writes and executes code against user-supplied data to produce charts, computed answers, or downloadable output files.

  4. Memory context — stories about memory context in this arenaHave the assistant remember relevant context from previous chats and apply it in new conversations

    nonemoves PA Scoreimpact 30

    The evidence pack shows conversation storage (grok-docs-21) and cross-device sync of conversations/settings (grok-docs-41), but nothing describing a memory feature that recalls relevant context from past chats and applies it to new, unrelated conversations.

  5. Openness — open source, data portability, and self-hosting storiesExport all of my data in open formats and leave

    nonemoves PA Scoreimpact 30

    No evidence pack item mentions any data export feature, open format (e.g., JSON/Markdown conversation export) or account data portability tool for Grok; documentation covers connectors, models, and billing but never data export/leave-with-your-data capability.

  6. Openness — open source, data portability, and self-hosting storiesSelf-host the core product

    nonemoves PA Scoreimpact 30

    Grok is a closed, proprietary API/cloud service; no evidence anywhere in the pack of open-sourced weights or a self-hostable core model/product, only hosted APIs, connectors, and SaaS features.

  7. Privacy posture — data-handling and privacy storiesPrevent my data from being used to train AI models

    nonemoves PA Scoreimpact 30

    The evidence pack documents data retention (prompts and responses stored on xAI's servers, grok-docs-21) and vague 'enterprise-grade privacy protections' for team workspaces (grok-docs-13), but nowhere mentions an opt-out toggle, training-data exclusion setting, or policy statement about excluding user conversations from model training.

  8. Trust controls — stories about trust controls in this arenaControl whether my conversations are used to train models

    nonemoves PA Scoreimpact 30

    Docs mention 'enterprise-grade privacy protections' for team workspaces and that prompts are stored on xAI servers, but there is no documented setting or toggle letting a knowledge-worker control whether their conversations are used to train models.
