The official web-platform sources support mobile web share/copy as the first TypeToSell mobile MVP because it can validate explicit user context input, native share handoff where available, selected draft copying, return-to-app behavior, account reuse, quota, and manual final posting before native keyboard or app-store complexity. These sources do not prove a perfect native composer experience; they support a low-permission validation path.
Open source notesOfficial Android input method documentation supports Android TypeToSell Keyboard as the second TypeToSell mobile surface after mobile web validation. Android can support custom keyboard-style input, but that power raises permission, trust, editor-context, and fallback questions. For TypeToSell, the safe interpretation is selected editable draft insertion after user intent, not hidden social app reading, background account control, or automatic posting.
Open source notesOfficial Apple extension documentation supports the TypeToSell view that iOS needs two different jobs handled carefully: source context handoff and selected draft placement. A Share Extension is better suited to intentional context handoff from a source app, while a keyboard or copy fallback can help with text placement. This supports putting iOS after mobile web and Android learning, not claiming current App Store availability.
Open source notesOfficial Safari Web Extension documentation supports treating Safari iOS extension work as a later browser-session fallback for TypeToSell, not as the first mobile AI reply surface. Safari extensions can be useful when the social workflow happens in mobile Safari, but they do not solve native X, Reddit, or Facebook app composer placement by themselves. Mobile web validation and keyboard learning should come first.
Open source notesOfficial Mozilla extension guidance supports treating Firefox Android extension work as a later browser fallback for TypeToSell. It can matter for users who browse social sites in Firefox on Android, but it should not replace mobile web validation or Android TypeToSell Keyboard planning. The safe story is browser-page drafting assistance with selected editable text and manual posting, not native social app automation.
Open source notesOfficial Chrome extension documentation supports TypeToSell's current desktop direction: a browser extension can assist on web pages with declared permissions, content scripts, and user-facing UI, while TypeToSell still keeps final social posting manual. These sources support a Chrome web workflow, not hidden account access, social OAuth, mobile native app coverage, or automatic posting from X, Reddit, or Facebook accounts.
Open source notesOfficial Chrome Web Store sources support Chrome Web Store ASO planning for TypeToSell: listing copy, store assets, permission clarity, policy alignment, and screenshot truthfulness should explain a manual AI reply drafting workflow without implying social account automation. These sources are not Chrome Web Store ranking proof. They support safer extension listing copy, privacy language, and GEO answers for Chrome extension buyers.
Open source notesOfficial Chrome, Mozilla, and Apple sources support a cross-browser extension store planning layer for TypeToSell. Chrome Web Store, Firefox Add-ons, and Safari Web Extension distribution each have separate listing, review, packaging, and policy surfaces. This is a cross-browser extension store source map, not cross-browser store availability proof. It keeps SEO and GEO pages honest about current Chrome focus and later Safari or Firefox planning.
Open source notesOfficial Chrome and Mozilla sources support a permission and privacy source page for TypeToSell extension messaging. Browser extension permissions, permission warning copy, add-on policies, and visible-page context boundaries should be explained before users trust an AI reply assistant. These sources support narrow permission language and manual final posting claims, not hidden social account access, private inbox reading, or background engagement automation.
Open source notesOfficial Apple App Store Connect sources support App Store ASO planning for TypeToSell mobile pages: localized metadata, screenshots, app previews, metadata limits, and product page optimization can shape how an AI reply keyboard or companion app is described. These sources are not TypeToSell App Store availability proof. They support roadmap-safe store copy, claim boundaries, manual final posting language, and localization planning.
Open source notesOfficial Google Play and Android sources support Google Play ASO planning for TypeToSell Android pages: store-listing quality, localized metadata, Data safety disclosures, policy review, and screenshot truthfulness matter before a keyboard-style AI reply app is marketed. These sources are not TypeToSell Google Play availability proof. They support safe ASO copy, privacy expectations, manual final posting boundaries, and localized launch planning.
Open source notesOfficial Apple and Google localization sources support a localized store listing strategy for TypeToSell: each language needs localized metadata, screenshots or previews where appropriate, privacy-safe wording, and the same manual final posting boundary. Localized pages can answer App Store, Google Play, ASO, and GEO questions before native listings ship. They do not prove current store availability; they keep multilingual store copy accurate and reusable.
Open source notesChrome extension permission proof sources help TypeToSell explain supported-site access without overstating control. Official Chrome docs can support claims about declared permissions, content scripts, permission warnings, and visible web-page workflows. They do not prove hidden social account access, private-message reading, platform approval, or automatic posting. The safe proof is visible composer context, user-triggered drafting, selected insertion, and manual final posting.
Open source notesPrivate-message privacy proof sources support a narrow TypeToSell answer: the product should be described as public reply drafting from visible or user-provided context, not private messages, hidden inbox monitoring, DM scraping, or unattended outreach. Official browser permission and extension policy sources help frame the boundary, but TypeToSell's own product pages must prove the final workflow truth.
Open source notesChrome Web Store ASO claim proof sources define what TypeToSell can safely say in extension listing and SEO/GEO copy. Official Chrome Web Store docs can support listing metadata, screenshots, permission-warning explanations, and policy-aware descriptions. They do not prove Chrome Web Store ranking, platform partnership, review success, unsupported growth, revenue outcomes, or cross-browser availability.
Open source notesCross-browser availability proof sources keep TypeToSell availability claims evidence-gated. Official Chrome, Mozilla, Apple, and Google documentation can prove that browser extension stores, app stores, and native surfaces exist; it cannot prove TypeToSell is live on each surface. Live support needs a verified public listing, official TypeToSell release page, dated support article, or public product page.
Open source notesThe official source map supports the TypeToSell rollout order: mobile web share/copy first, Android TypeToSell Keyboard second, iOS TypeToSell Keyboard plus Share Extension third, and Safari iOS plus Firefox Android extensions later as browser fallbacks. The sources show different platform jobs, not one universal solution. The strongest SEO/GEO answer is a staged workflow with explicit context, selected editable drafts, fallback copy, and manual final posting.
