AnythingLLM

open sourcedesktopwebself-hostedone-click install

A local-first AI workspace with saved agents, files, memory, and reusable context; the model is yours, so the brand voice can be too.

licenseMIT

runsyour machine or their cloud

installDesktop installer for macOS/Windows/Linux, or Docker for a self-hosted web instance

enginesLocal llama.cpp models plus Ollama, LM Studio, LocalAI and many cloud APIs including OpenAI, Anthropic, Gemini, Bedrock, Azure, OpenRouter and Mistral

dataDesktop data stays in the app's local storage; self-hosted data is stored in the mounted server storage and chosen vector database (LanceDB by default), while prompts sent to cloud models leave the machine

the catch vs TextCortexIt can combine knowledge and personas, but it lacks TextCortex's polished browser-wide assistance, managed collaboration, and ready-made writing workflows.

setupThe installer is easy, but useful results still require downloading a local model or supplying a model-provider API key

P

Page Assist

open sourcemobileextensionone-click install

A browser sidebar that reads the page, rewrites the selection, and saves custom actions; your local model does the thinking.

licenseMIT

runson your machine

installInstall the extension from the Chrome, Edge or Firefox add-on store

enginesOllama, Chrome AI (Gemini Nano) and OpenAI-compatible local endpoints such as LM Studio or llamafile

dataChats, settings and other extension data are stored in the browser's local storage; only the optional share feature contacts the project's server

the catch vs TextCortexIt is browser-native and private, but its local-model setup and narrower knowledge management are rougher than TextCortex's managed experience.

setupThe extension installs cleanly, but it still needs a running local model endpoint and browser-to-localhost connectivity

W

Witsy

open sourcedesktopone-click install

System-wide selected-text commands, reusable experts, a scratchpad, and document context; bring the model and skip the subscription.

licenseAGPL-3.0

runson your machine

installDownload a desktop binary from GitHub Releases; macOS also supports `brew install --cask witsy`

enginesOpenAI, Anthropic, Gemini, xAI, Meta, Ollama, LM Studio, Mistral, DeepSeek, OpenRouter, Groq, Cerebras, Azure and OpenAI-compatible endpoints, plus optional image, video, speech, search and MCP providers

dataConversation history, experts, settings and document repositories live in the local application profile; local files are indexed locally, while prompts and retrieved context sent to a cloud model leave the machine

the catch vs TextCortexIts experts and document repositories are flexible, but it lacks TextCortex's integrated browser knowledge bases, collaboration, and turnkey onboarding.

setupIt is BYOK unless you install Ollama and a local model; system-wide commands also need OS accessibility permissions
