DeerFlow is a self-hosted AI agent application for research, coding and content creation on your own infrastructure. It supports local models through Ollama and vLLM, including Qwen3, as well as hosted providers. With a cloud provider, model requests leave your server and may incur provider charges.

MS Agent is an open source Python agent framework with a self-hosted web server for working on local projects. It's for developers building research assistants and coding workflows that continue across sessions. Code execution and project file work run locally; the default model integration uses ModelScope's API and requires an API key and internet access.

Qube is a desktop AI assistant for people who want to chat with models and work with private documents on their own hardware. It combines a document library with persistent memory and research tools that provide citations you can inspect.

Marginalia is a research agent for people whose papers, notes and working files are spread across a mixed document library. It reads relevant parts of the original files before writing answers with citations.

Speakr is a self-hosted transcription and note-taking app for people who need to revisit meetings, interviews or lectures. It pairs recordings with searchable transcripts and AI summaries.

Oleafly is a desktop editor for researchers writing papers, theses and other long documents in LaTeX, Typst or Markdown. It brings the manuscript, PDF preview and research tools into one workspace, with projects stored as ordinary files you own.

HyperResearch is a research agent for Claude Code and OpenAI Codex that produces cited reports and keeps sources for later questions. It's for researchers who want to review the evidence behind a report and reuse their collected material.

LLM Wiki is a desktop AI knowledge base for people building a research library or personal reference collection. It creates lasting, linked pages from your documents and updates them as your sources change.

SearchBox searches inside documents for people who remember a topic or phrase but can't find the file it came from. It keeps existing folders in place and makes their contents searchable.

JARVIS RD Assistant is an open source, self-hosted workspace for researchers who want to search scientific literature and trace AI-generated answers back to papers. It runs on your own hardware with Ollama and connects literature review with PDF annotation, learning cards and research projects. It uses the Apache 2.0 license.

Atomic Agent is a local AI agent for people who want an assistant to work with their browser, files and code on their own hardware. Its model and task loop can run offline, while sessions and memory stay on disk. It's free and open source under the MIT license.

Surf is an AI notebook for people researching across webpages, videos and documents. It brings source material and writing into one workspace so you can ask questions about what you've collected while taking notes.

wigolo gives AI agents web access from a server on your own machine. It's for developers who want coding assistants or self-hosted agents to gather web evidence and reuse what they've already fetched.

Kady is an AI research assistant for scientists who want to turn plain-language requests into analyses, literature reviews and research outputs. It works in a desktop workspace where you can inspect its code and files, redirect ongoing work or stop a run.

Tessera is a self-hosted literature review workspace for researchers who want to find papers, keep reading notes and compare findings in one browser interface.

PipesHub connects company knowledge to AI search and agents for teams whose files and conversations sit across business apps. It can also supply that context to coding assistants and custom applications.

Assistant is a self-hosted AI agent for people who want to delegate work by email and receive the results in their inbox. It uses a dedicated mailbox, separate from your personal email, and also accepts tasks through a browser workspace or dashboard. You control how much autonomy it has.

Starcat is a native macOS app for developers who want to find and evaluate repositories they've saved on GitHub. It keeps a local library and lets you choose which repositories enter a private AI knowledge base.

SearXNG is a self-hosted metasearch engine for people who want to combine search services without user tracking or profiling. It's a fork of searx, and web searches require internet access because external services supply the results.

Open Science Desktop brings research agents, notebooks and project files into one workbench for researchers who want to inspect the work behind an AI-generated result. Agents can carry a research topic through literature review, experiments, analysis and manuscript writing.

Taskyon is a browser-based AI workspace for people investigating technical problems and developing engineering designs. It keeps the work in a task tree so related questions, evidence and decisions stay connected.

Lexora is a personal desktop AI agent for research, creative projects and everyday planning as well as coding. It works toward a goal while you give direction and review its work.

AutoRAG Agent searches documents and connected archives where they already live, then reads the relevant sources to produce answers with file, page or line references. It runs on macOS, Windows and Linux and suits people researching information spread across local files, messages and notes.

AIlice is an open source AI agent that runs on your own machine and handles tasks spanning research, software development and system administration. It's for people who want an assistant that can act on files, browse the web and execute code. Its Interactive Agents Call Tree architecture splits complex requests among agents created for the task, then combines their results.
