Show HN: Anvit – Offline AI to chat with your PDFs on Android on-device
Anvit is an Android app that lets users chat with their PDFs using an offline AI, processing everything entirely on-device without an internet connection.
Background
- Show HN is a section on Hacker News where users share personal projects for feedback — appearing there often signals a solo or small-team maker.
- "On-device" / "offline AI" means the model runs directly on the phone, not over the internet. This matters for privacy and for regions with poor connectivity. Most comparable apps (ChatGPT, Gemini, NotebookLM) require a cloud connection to process PDFs.
- Anvit appears to be an Android app (Google Play listing). The developer is Likith, an Indian maker who previously built other offline tools, suggesting a niche in practical, resource-efficient mobile AI.
- The core idea: you upload a PDF and ask questions about it in natural language, and the phone's own AI answers — no data leaves the device. This is technically challenging because large language models are memory-heavy and PDF parsing adds complexity.
- Why it matters: it points to a trend where capable AI runs on consumer hardware without server costs or privacy trade-offs, potentially making document analysis accessible to users who cannot or will not use cloud-based services.
