A new database
for AI memory.
Run AI queries against your own data, locally on your laptop. KOSHA bundles Google's Gemma 4 — most queries never leave your machine. Optional cloud fallback for harder questions, your API key, your traffic.
V0.2 is the proof-of-life build — confirms install, initializes the local database (11 tables on first launch), detects Ollama. Sign-in and the AI query loop ship in V1.0.
First launch: right-click the app → Open (the build is unsigned during private beta). Apple Silicon only (M1/M2/M3/M4). Intel Mac build coming.
Anonymous usage stats are collected during the private beta — counts only, never your queries or data.
Local-first by default. Cloud only when you choose.
Download the .dmg
Sign in with Google. KOSHA creates a private workspace on your Mac. First run downloads Gemma 4 (about 7 GB) so the database can answer questions without calling the cloud.
Drop in your facts
Notes, chats, paragraphs — anything. KOSHA organizes them into eight named categories (Work, Family, Health, Finance, …) you can rename to fit your life.
Query, locally
Ask in plain English. KOSHA finds the relevant facts and runs the question through your local Gemma 4. A green dot in the menu bar confirms zero tokens sent to any cloud.
Honest about what stays local and what doesn't.
Local by default. When Gemma 4 is running on your Mac, every query stays on your laptop. KOSHA never sends your data anywhere.
Optional cloud fallback. If Gemma stops, KOSHA can use a cloud LLM you choose (Gemini, OpenAI, or Anthropic) with your own API key. The provider sees your prompt; KOSHA does not store the response. You can turn cloud fallback off entirely in settings.
Anonymous usage stats during private beta. KOSHA sends counts (number of records, tokens saved) once a day so we can improve the product. Never the content of your queries or your stored data.
Your data, your file. KOSHA keeps everything in a single SQLite file on your Mac. Back it up, copy it, delete it — it's yours.
