Parts Research & Comparison
Parts Research Center
Record actual listings and fitment evidence yourself. ModifiedAI does not verify links, part numbers, prices or claims. Research records are stored with each part in named saves and JSON backups.
Compare researched options
Preferred is a shopping choice, not a fitment approval. You can select any recorded option for the budget above.
Saved Builds & Backups
My Saved Builds
Backups are downloaded to your device. Keep a copy somewhere safe. Import never deletes existing builds.
Saving creates a separate snapshot. Changing vehicles or editing your current build will not change saved projects unless you explicitly save again with the same name. Saved builds stay in this browser on this device only.
Planning & checks
Build Readiness Checklist
Build Readiness Checklist
Track planning tasks, not mechanical approval. A completed checklist does not certify fitment, safety, emissions legality, or installation quality.
Project Stages
Project Stages
These stages track planning only. Completing them does not certify installation, fitment, safety or legality.
Parts Dependencies & Missing-Plan Alerts
Parts Dependencies & Missing-Plan Alerts
Conceptual supporting-system reminders based on your selected build path; not a verified parts requirement.
Build Intelligence
Build Intelligence
Vehicle-aware planning guidance. These are not catalog-verified part numbers or proven fitment. Expand each item to understand its role and what to confirm.
