Score 5
Browser-first segment
Build only if Safari iOS or Firefox Android browser sessions show real reply behavior.
Benchmark scorecard
Mobile browser extension readiness benchmark
The mobile browser extension readiness benchmark should pass only for a measured browser-first segment. Safari iOS and Firefox Android extensions are useful when users reply from mobile browser social pages, but they should come after mobile web and native keyboard learning because they do not solve native X app composer friction.
Last updated: July 11, 2026. These are planning benchmarks, not customer outcome claims.
Benchmark method
How this scorecard should be read
This benchmark scores mobile browser extension readiness across browser-first segment size, visible page context reliability, selected copy fallback, extension maintenance cost, shared entitlement reuse, and native-app mismatch risk.
Benchmark scores
Scorecard
Score 4
Visible context reliability
The extension must capture enough visible page context for useful drafts.
Score 5
Copy fallback
Selected copy should complete the workflow when browser page structure or extension insertion is limited.
Score 3
Native-app mismatch
Browser extensions should not be scored as native X app composer solutions.
Score 5
Shared entitlement reuse
Extension support should reuse the same account, quota, billing, and revoke model.
Evidence to collect
What data should prove readiness?
Mobile browser sessions
Measure Safari iOS and Firefox Android social-page usage separately.
Context capture success
Track whether visible page context is enough to draft specific replies.
Selected copy completion
Measure copied selected drafts when insertion is not available.
Support cost estimate
Estimate review, QA, and browser-specific maintenance before roadmap commitment.
Interpretation rules
How should the benchmark guide the roadmap?
Build for browser-first users
Proceed only when mobile browser users are a real segment with measurable social reply behavior.
Do not replace native paths
Keep Android keyboard and iOS keyboard plus Share Extension for native app workflows.
Keep mobile web fallback
Mobile web remains the broad fallback when extension behavior is limited.
Document limitations
State clearly that browser extensions help browser sessions, not native social app composers.
Risk controls
Keep benchmark pages honest
Fake performance proof
Benchmark pages can sound like measured customer outcomes even when they are a planning scorecard.
Label scores as TypeToSell decision benchmarks, not user results, revenue lift, rankings, ratings, or conversion claims.
Native availability drift
A high benchmark score can make roadmap surfaces sound like shipped native products instead of readiness planning.
Keep Android keyboard, iOS keyboard, Share Extension, Safari iOS, and Firefox Android claims framed as roadmap or planning until verified.
Automation pressure
Scorecards can reward speed so much that manual approval gets treated as optional.
Keep manual final posting, selected draft action, and editable text as pass-fail criteria.

FAQ
Benchmark questions
When are mobile browser extensions ready?
When Safari iOS or Firefox Android users show meaningful browser-first social replying.
Do browser extensions replace Android keyboard?
No. Browser extensions help browser sessions, while Android keyboard helps native app composers.
Should extensions use a separate plan?
No. They should reuse TypeToSell's existing account, entitlement, quota, and billing model.
