# Birder AI

> Birder AI is an iOS app that identifies birds from a photo or sound in seconds, builds your life list, and connects you with a community of birders. Powered by GPT-4o vision and BirdNET.

Birder AI is an AI-powered iOS app for bird identification, birdwatching journaling, and birding community. Photo identification uses OpenAI's GPT-4o vision with structured outputs and regional/seasonal context. Sound identification uses BirdNET, the open-source bird audio classifier developed by the Cornell Lab and the Chemnitz University of Technology. Reference photos are CC-licensed from iNaturalist; sound recordings are CC-licensed from xeno-canto; taxonomy is from the eBird/Clements Checklist.

Birder AI is a paid subscription app: $4.99/month or $49.99/year, billed through Apple. Every new account starts with a 3-day free trial that unlocks the full app — unlimited photo and sound identifications, the higher-accuracy GPT-4o vision tier, advanced stats, year/yard lists, and "recent nearby" species data. There is no permanent free tier; users who do not subscribe after the trial lose access to identifications.

## How AI identification works in Birder AI

Photo identification:
1. Image is compressed to ~1024px JPEG client-side.
2. Image, latitude/longitude, and date are sent to OpenAI's Chat Completions API with response_format set to a strict JSON schema.
3. Model returns up to 5 candidate species ranked by confidence, the visible features supporting each ID, and an image-quality assessment.
4. Each candidate is mapped to our internal species database by scientific name (eBird/Clements taxonomy).
5. User confirms a species, which creates a sighting record.

Sound identification:
1. User records up to 30 seconds of audio.
2. Audio is uploaded and processed by a BirdNET service.
3. Results include species and timestamps within the recording.

All paying subscribers (and users in their 3-day free trial) use gpt-4o with "high" image detail. Identical images are deduplicated by SHA-256 hash within a 24-hour window to save cost on retries.
