The Grok glyph lives in the post header, exactly where X shipped it. One tap opens a tooltip with the four shortcuts every post is hired for: Summarize, Is this true?, Explain, Open in Grok.
A pixel-level argument for treating Grok as ambient infrastructure inside the timeline - not a destination users have to walk to. Six surgical insertions, ordered by impact. One monochrome system. Zero new tabs.
What this gives you: a designer who already ran the thesis, the visual board, the working prototype, the 90-day plan, and the rollout gates - so the first conversation can be about what to ship, not whether the candidate gets it.
The working product, a near pixel-exact x.com/home. Tap the corner Grok button on any post and watch the answer stream in. Live ticker, breaking-posts pill, thread synthesizer.
The bookmark organizer. Connect a real X account over OAuth, and Grok clusters your saves into themed collections so a graveyard of bookmarks becomes a two-minute review.
One page that maps the whole proposal. What it is, who it's for, what each page argues, with a live demo in every themed section.
Grok Organize connects a real X account over OAuth, reads your bookmarks, and clusters them into themed collections so a saved pile becomes a two-minute review. The prototype is now a near pixel-exact x.com/home, X's real recommendation algorithm is documented and wired into how saves get ranked, and all 26 pages now share one navigation spine.
Every Grok affordance lives inside the timeline, post detail, or compose. No new top-level tab. The destination model is the failure mode this whole spec is structured to avoid.
Grok answers expand inline below the post that prompted them. Scrolling away dismisses. No modals. No close buttons. No state to manage.
Every Grok-rendered claim carries source chips and an explicit confidence indicator. Hidden uncertainty is dishonest. Showing it builds the calibration loop users need.
Grok surfaces underlying data. Users draw conclusions. Community Notes already does fact-checking with strong governance - that's the right tool for that job.
One Grok mark, one inner-border treatment, one motion curve. No purple. No gradients. No "AI shimmer." The restraint is the point - X earns its severity, and Grok earns its place by respecting it.
400ms first token. 1.5s full answer. If we can't hit budget on a surface, we don't ship that surface. Slower than scrolling is dead on arrival.
One-tap "what's this about" answer anchored to any post. The cell expands; the user never loses their place.
Consensus / disagreement / notable summary above any thread with ≥8 replies. Visibly generated, collapsible, sample-size disclosed.
Quiet "context available" affordance on posts with checkable claims. Context, never verdict. Sources first.
Private draft review - sharpen, steelman, check. The lurker participant conversion lever.
Adjust your algorithm in plain language. Diff before apply. The moat.
Query X's history as a real timeline, filtered to your interest graph. Ship after 1–4 prove out.
