About

Oh Pi App

Features
Read full description

Oh Pi App brings your self-hosted AI development workspace to iPhone and iPad. Connect to your own ohpi-gateway directly or through an encrypted SSH tunnel, then work with your files and AI tools wherever you are. • Chat with your configured AI provider and follow streaming responses, reasoning and tool results. • Create, resume, rename and delete conversations across multiple workspaces and servers. • Browse remote files and inspect code, images and tool output. • Schedule tasks and manage their execution from your device. • Configure provider credentials on your server and choose models for each conversation. • Use SSH password or private-key authentication with server fingerprint confirmation. • Enjoy layouts for iPhone and iPad, light and dark appearance, and English and Simplified Chinese. A compatible server and your own AI provider access are required for normal use. You can connect to an existing gateway or install one on a machine you control using SSH. AI requests and tools run on your configured server; provider charges and terms may apply. Before sharing content with an AI provider, the app explains the data being sent and requests your permission. The Oh Pi developer does not operate a conversation relay server.

Your Markdown knowledge, within reach. Mementara brings your GitHub repositories to iPhone and iPad for focused, offline reading. Download a selected repository, choose a branch and root folder, and keep your notes available wherever you are. YOUR SECOND BRAIN, READY TO READ Keep your second brain within reach. Read supported Markdown notes from an Obsidian vault stored in a GitHub repository, with offline search, wikilinks and supported note embeds. Mementara is an independent reader and is not affiliated with Obsidian. NO ACCOUNT NEEDED FOR PUBLIC REPOSITORIES Explore the bundled sample or browse and download public GitHub repositories without signing in. Enter a repository URL, owner/repository name or GitHub username to find public repositories. A GitHub account is optional and is required only to access private repositories. READ AND EXPLORE Follow relative links, wikilinks and supported note embeds. Read Markdown, code, tables, math and Mermaid diagrams. Open cached images and PDFs, save bookmarks and return to your reading position. FIND WHAT YOU NEED Search downloaded notes and filenames, then open matching passages in context. Search works offline and does not send your queries to an AI service. YOUR REPOSITORY STAYS YOURS Mementara connects directly to GitHub and never edits your source files or writes changes back. For private repositories, sign in to GitHub and grant read-only access to selected repositories. Credentials stay in device-only Keychain storage. The app includes no advertising or analytics SDK.

The interface supports English, German, French and Spanish. Free to use, with no in-app purchases or subscriptions. Requires iOS or iPadOS 18 or later.
