AnythingLLM
open sourceMITLocal or hosted64kaug 2026Point it at your files and bring your own model; the privacy is free, the compute is not.
The catch vs AfforaiIt can search and cite local files, but setup, citation checking, side-by-side source comparison, and a managed research workspace require more work than Afforai.
Install, platforms & data +
- platforms
- desktopself-hostedone-click install
- install
- Install the one-file Windows, macOS, or Linux desktop app, or run the self-hosted Docker image with a persistent storage volume
- setup
- The app installs cleanly, but useful private operation still requires choosing and downloading a model that fits the machine; the server route also requires Docker and correct volume mounting
- engines
- Built-in llama.cpp/GGUF plus Ollama, LM Studio, LocalAI, OpenAI, Anthropic, Gemini, Bedrock, Mistral, OpenRouter, and other providers; embeddings and vector stores can also be local or external
- your data
- Desktop data lives in a local AnythingLLM storage folder containing anythingllm.db, parsed documents, vector indexes such as LanceDB, caches, and optional GGUF models; Docker uses the mounted storage volume, while external providers receive retrieved context

Open Notebook
open sourceMITSelf-host36kaug 2026NotebookLM on your own server; bring Docker, a model and realistic expectations about citations.
The catch vs AfforaiIt offers ownership and model choice, but Docker, provider configuration, and less mature citation and comparison polish are the price of leaving Afforai.
Install, platforms & data +
- platforms
- webself-hosteddocker to self-host
- install
- Deploy the documented Docker Compose stack; source and manual installation paths are also available
- setup
- Docker is the first hurdle, followed by supplying at least one provider API key or setting up Ollama and assigning models to the required roles
- engines
- More than a dozen configurable providers including OpenAI, Anthropic, Gemini/Vertex, OpenRouter, Ollama, and LM Studio, assigned separately to chat, embeddings, text-to-speech, and speech-to-text roles
- your data
- Uploaded sources, generated audio, and checkpoints live in the mounted ./data directory, while notebook records and indexes live in the mounted SurrealDB data directory

NotebookLM
freeproprietary, freeHostedUpload the papers and interrogate them; Google pays the model bill and keeps the limits.
The catch vs AfforaiIt is exceptionally easy, but sources live in Google's cloud, free notebooks have fixed source limits, and structured multi-document comparison and export are less controllable than Afforai's.
Install, platforms & data +
- platforms

- install
- Sign in with a Google account in the hosted web app; optional mobile apps are available
- setup
- A Google account and cloud upload or synchronization of the research sources are required
- engines
- Google Gemini models selected and operated by Google; the exact production model behind each notebook feature is not consistently exposed to the user
- your data
- Uploaded sources are copied or synced into Google's cloud and notebooks retain chats and generated artifacts; the free service limits a notebook to 50 sources, up to 500,000 words or 200 MB per source
