TrackAI
A small, useful photo-calorie workflow can be built by one technical user using hosted vision APIs and public nutrition data, but matching the vendor's accuracy, mobile polish, and proprietary datasets/model tuning would be hard to fully replicate.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All TrackAI alternatives, with the arithmetic →
What a replacement has to do
- User takes/uploads a photo → run image analysis to identify dish and ingredients → estimate portion size and map to nutrition database → present editable calorie/macro breakdown → save entry and update analytics/streaks
What it still won’t have
- Proprietary, highly-tuned food-vision training data and models the vendor may have
- Polished mobile UX and cross-platform native performance
- Existing user base, reward system, and engagement data
- Any private integrations TrackAI may add (Apple Health, fitness trackers) and push-notification infrastructure at scale
- Ongoing benchmarking and labeled food-photo datasets for higher accuracy
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal photo-based calorie-tracking web app using Next.js (React) frontend, Node.js/Express backend, Postgres for storage, and AWS S3 for photos. Use a hosted vision API (e.g., Hugging Face or OpenAI vision endpoints) for ingredient/dish detection and implement a server-side mapping service that matches detected items to a nutrition table (USDA or public nutrition dataset). Implement portion-estimation heuristics using detected bounding boxes and optional user-supplied reference object/scale. Core features in scope: photo upload, vision inference integration, nutrition mapping and calorie/macro calculation, editable meal entry UI, persistent logging, daily/weekly analytics dashboard, simple user auth, and basic reminders (email). Out of scope: training custom vision models, native mobile apps, advanced image calibration. Include robust error handling for API failures, input validation, and unit/integration tests for inference, mapping, and persistence.

- 2 cited sources+1
- 3/3 assessment runs agreed+4
- Evidence score62
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
