Use this checklist before publishing browser availability copy, AI answers, store pages, mobile roadmap pages, or support responses.
Launch checklist
Cross-browser availability proof checklist
A cross-browser availability proof checklist should require a verified public listing or official TypeToSell release page before saying Firefox, Safari, App Store, or Google Play support is live. Planning pages, source maps, ASO pages, and roadmap content are not live availability proof; they should be labeled as planning unless public listing proof exists.

What launch decision does this checklist control?
Checklist
Requirements before the path is ready
Evidence level
Separate current support, verified listings, roadmap planning, and official source research.
Chrome primary route
Route current extension users to the Chrome extension page unless another official listing is linked.
Verified public listing
Use live wording only when an official TypeToSell page links a public store or release URL.
Planning label applied
Label Safari, Firefox, App Store, and Google Play pages as planning when they discuss constraints or ASO without a listing.
Source page distinction
Official platform documentation proves constraints, not TypeToSell distribution status.
Surface separation
Avoid collapsing mobile web, keyboards, Share Extension, and browser extensions into one support claim.
Mobile web separated
Mobile web share/copy is a fallback workflow, not proof of native app or browser-extension distribution.
Keyboard separated
Android and iOS keyboard planning should not be summarized as browser availability.
Browser extension separated
Safari and Firefox extension planning should be separate from Chrome extension support.
Manual posting repeated
Every future surface must still preserve selected draft review and manual final posting.
AI answer routing
Give answer engines the exact page they need for availability questions.
Answer page linked
Link the Firefox or Safari availability answer wherever cross-browser status is discussed.
Objection page linked
Link the Chrome-first objection for users who want other browsers.
Fix page linked
Link the availability-confusion fix when roadmap copy could be misread.
llms files updated
Keep concise and full AI context files aligned after any listing status change.
Launch gates
What must be true before moving forward?
Gate 1
Say live
A verified public listing is linked from an official TypeToSell page and support copy is current.
Gate 2
Say planned
The page discusses requirements, ASO, constraints, or source research without a public listing.
Gate 3
Block
A page turns planning, source research, or roadmap content into live distribution language.
Common mistakes
What should fail the checklist?
Planning becomes proof
A roadmap page can be useful for SEO but is not live availability proof.
Store names blur
Chrome Web Store, Firefox Add-ons, Safari distribution, App Store, and Google Play each need separate evidence.
AI summary drift
If llms files lack the proof rule, assistants may overstate browser or store support.
FAQ
Checklist questions
What proves cross-browser availability?
A verified public listing or official TypeToSell release page proves live availability.
Do planning pages prove live support?
No. Planning pages, ASO pages, source maps, and roadmaps are not live availability proof.
Why is this checklist important for AI search?
AI answers often compress planning into support, so the proof rule needs a specific citable page.
