Google Gemini costs $19.99/mo — $239.88 a year. These 8 alternatives replace it for $0, led by AnythingLLM, Cherry Studio and Jan. All 8 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
A private AI desk for documents and agents; install it, then choose local models or somebody else's meter.
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 Google GeminiIt cannot reproduce Gemini's first-party Gmail, Docs, Drive, Android, and Google Search integration, and it includes no Google AI Pro model quota.
setupThe installer is easy, but useful results still require downloading a local model or supplying a model-provider API key

A desktop model switchboard with assistants, files, agents and MCP; bring keys or make your laptop sweat.
licenseAGPL-3.0
runson your machine
installDownload the signed desktop installer for macOS, Windows or Linux
enginesOpenAI, Anthropic, Gemini and many other cloud APIs; Claude, Perplexity and Poe web integrations; local models through Ollama or LM Studio; OpenAI-compatible endpoints
dataChats, assistants and settings are stored in the desktop app's local profile; optional WebDAV backup/sync and cloud model calls copy relevant content to those services
the catch vs Google GeminiIt makes you supply each model and account yourself and cannot match Gemini's first-party integration across Google's apps and services.
setupThe app installs cleanly, but the first useful chat requires an API key or a separately installed local model server

A local-first desktop assistant with cloud connectors and tools; your RAM gets the invoice.
licenseApache-2.0
runson your machine
installDownload the macOS, Windows or Linux desktop installer
enginesBuilt-in local inference via llama.cpp/llama-server plus OpenAI-compatible APIs and connectors such as OpenAI, Anthropic, Gemini, Groq, Mistral and OpenRouter
dataThreads, assistants, settings and downloaded model files live in Jan's local data folder; only requests sent to configured cloud providers leave the machine
the catch vs Google GeminiIt can provide local or bring-your-own-model chat, but not Gemini's included frontier-model access or native Google ecosystem integration.
setupLocal use requires downloading a multi-gigabyte model and enough RAM; cloud use requires an API key

A self-hosted model switchboard with agents, files and tools; free software, paid model bills if you use paid models.
licenseMIT
runsyour server
installClone the repository and start the recommended Docker Compose stack
enginesOpenAI, Anthropic, Google Gemini/Vertex AI, Azure OpenAI, AWS Bedrock, Mistral, Groq, OpenRouter, DeepSeek and custom OpenAI-compatible endpoints, plus agents and MCP
dataConversations, users and configuration live in MongoDB; search indexes use Meilisearch, uploaded/RAG content uses bundled storage and a vector database; prompts sent to cloud models leave the host
the catch vs Google GeminiIt adds server administration and separate model bills while still lacking Gemini's native Gmail, Docs, Drive, Search, and Android integration.
setupDocker Compose brings several services, and the default MongoDB image does not run on Apple Silicon without changing the setup

A local-first multi-model workspace with files, search, code and personas; the interface assumes you enjoy buttons.

enginesOpenAI, Anthropic, Gemini, Azure, Bedrock, DeepSeek, Groq, Mistral, OpenRouter, Perplexity, Together, xAI, Ollama, LocalAI, LM Studio and OpenAI-compatible endpoints
dataThe open app stores chats and settings locally in the browser by default; hosted Pro adds synced cloud storage, and model requests go to whichever provider the user configures
the catch vs Google GeminiIt supplies a multi-model interface but not Gemini's included model allowance or first-party integration across Google Search, Gmail, Docs, Drive, and Android.
setupThe free hosted app is immediate, but it does not include model usage: the user must bring provider API keys and understand provider billing
