Workflow
How this mobile path works
Start with mobile web
Generate and copy drafts from a mobile browser while keeping the final X app post manual.
Add Android keyboard
Move drafting closer to the native X composer after activation is proven.
Add iOS keyboard and share
Pair composer insertion with share-sheet context handoff for iPhone users.
Add browser extensions
Serve Safari iOS and Firefox Android users who reply from mobile web social sites.
Alternatives
Compare the mobile reply options
1. Mobile web + share/copy
Fastest MVP
Paste or share post text into a mobile web tool, generate drafts, copy one, and return to the social app manually.
2. Android ReplyPilot Keyboard
Best Android in-app UX
A keyboard can appear inside the X app composer, but it should launch only after mobile web activation and account gates are stable.
3. iOS ReplyPilot Keyboard + Share Extension
Best iPhone coverage
A keyboard helps in composers while a Share Extension handles post handoff; both need strict privacy and App Group boundaries.
4. Safari iOS extension
Mobile browser fallback
Useful for people who use social sites in Safari rather than native apps, but not the fastest first MVP.
5. Firefox Android extension
Android browser fallback
Useful for mobile browser users who prefer Firefox, while native-app users still need web copy/share or keyboard workflows.
Decision criteria
What matters before building it
First principle
Ship the path that proves reply value fastest before building native wrappers.
Manual posting
Every channel should keep the user responsible for final editing and posting.
Single entitlement system
Use one TypeToSell account, plan, subscription, quota, and admin revoke model across channels.
