Bing Chat has been folded into Copilot, so if you came looking for a replacement you have options in two directions: cloud generalists like ChatGPT, Google Bard, Jasper, YouChat, and Chatsonic for broad web-aware chat, or a local, offline tool like GreenCube if you want your conversations and documents to stay on your own computer. For privacy and on-device document work, GreenCube is the pick worth testing first.
TL;DR:
- GreenCube’s Quick model handles plain text on modest hardware, while All-rounder reads images and builds documents but runs best with around 8GB of RAM.
- GreenCube requires a single model download, roughly 2GB for Quick or 4.2GB for All-rounder; afterward, it works without internet.
- Match the assistant to existing work: Copilot fits Microsoft 365, Bard connects with Google apps, and Jasper targets marketing and copywriting teams.
- Before trusting a local tool’s privacy claims, verify in its documentation whether telemetry, background syncing, and automatic updates can be switched off.
- Cloud assistants offer stronger models and live web access, while GreenCube trades those advantages for offline operation and a single payment.

Compact profiles of the leading alternative chatbots
Each of these tools solves a different problem, so the right one depends on whether you care more about raw capability, workplace integration, or keeping your data off someone else's server. Here's what each does well and how you get to it.
GreenCube runs entirely on your computer instead of in the cloud. At setup you pick one of two local models: Quick (Llama 3.2 3B), which is fast and handles plain text, or All-rounder (Gemma 4 E4B), which reads images and helps build study guides and documents but asks more of your hardware.
- Best for: privacy-first offline use and on-device document analysis.
- Access mode: fully local, no cloud processing of your chats or files.
- Primary strength: nothing you type or upload leaves your machine.
- Pricing model: one-time purchase.
ChatGPT remains the broadest generalist in the category, with a free tier, paid subscription tiers, and a large library of plugins and integrations that plug into other software you already use. Zapier's 2026 roundup places it alongside tools like Claude, Google Gemini, and Perplexity as a strong all-rounder, each with a different niche.
- Best for: general-purpose writing, brainstorming, and plugin-driven workflows.
- Access mode: cloud, via web and apps.
- Primary strength: breadth of integrations and conversational flexibility.
- Pricing model: free tier plus paid subscriptions.
Copilot is Microsoft's assistant, and it's built to sit inside the apps you likely already use for work. PCMag's testing notes that Copilot blends a language model with live web data and integrates deeply with Microsoft 365, which makes it a natural fit if your documents and spreadsheets already live in that ecosystem.
- Best for: Office productivity and in-app assistance inside Word, Excel, and Outlook.
- Access mode: cloud, with Windows and web integration.
- Primary strength: direct access to your Microsoft 365 files and context.
- Pricing model: free tier plus subscription tiers.
Google Bard is tuned for people who live inside Google apps. It pulls from web-aware answers and ties into Gmail, Docs, and Search in ways that feel native if that's where your work already happens.
- Best for: users who rely on Google apps and web-integrated search.
- Access mode: cloud, via browser and mobile.
- Primary strength: tight integration with the Google product suite.
- Pricing model: free, with some features gated behind Google subscriptions.
Jasper skews toward marketing and content teams rather than general conversation. Mashable's list of accessible alternatives names it alongside Bard, YouChat, and Chatsonic as a practical option when you need help producing copy at scale.
- Best for: content marketing and creative copywriting workflows.
- Access mode: cloud, subscription-based.
- Primary strength: templates and tools built specifically for marketers.
- Pricing model: subscription, no one-time option.
YouChat pairs a chatbot interface with search engine results, so answers come with citations and current context baked in.
- Best for: quick, web-aware answers that read like a search result and a chat at once.
- Access mode: cloud, via web.
- Primary strength: search-integrated responses.
- Pricing model: free, with optional paid features.
Chatsonic leans into speed and timeliness, generating content with current web context rather than relying only on a static training set.
- Best for: up-to-date, web-informed content creation.
- Access mode: cloud, subscription-based.
- Primary strength: fast output with current event awareness.
- Pricing model: subscription.
How do you pick the right alternative for your needs?
The honest answer depends on what you're optimizing for. Start with these criteria, in rough priority order, and you'll land on the right tool faster than by testing all seven.
- Decide how much you care about privacy and where your data lives: does the tool process everything locally, or does it send your messages and files to a server?
- Check whether offline operation matters to you: a local tool keeps working on a plane or in a dead zone; a cloud tool does not.
- Match the tool to your actual workflow: Microsoft 365 users benefit most from Copilot, Google users from Bard, and marketing teams from Jasper.
- Look at your device's RAM and processing power if you're considering a local option, since larger models need more memory to run smoothly.
- Compare the cost model: a one-time purchase versus an ongoing subscription changes the math substantially over a year or more.
- Weigh model strengths against your actual tasks: writing, coding, research, and image reading are not evenly distributed across these tools.
- Confirm platform support before you commit, especially if you split time between Windows, Mac, or mobile.
Pro Tip: Before trusting any "offline" or "local" claim, check the tool's documentation for telemetry, background sync, or automatic model updates, and make sure those can actually be switched off.
Going local buys you predictable costs and data that never leaves your machine, but cloud tools still lead on raw model power, real-time web access, and the newest features as they ship.
GreenCube spotlight: on-device privacy and practical setup
GreenCube is built for people who want a usable AI assistant without handing documents or conversations to a remote server. It runs on Windows now, with Mac support in development, and the license activates with a one-time sign-in through Google or Microsoft, used only to confirm your purchase.
- Two model choices at setup: Quick for fast plain-text chat, or All-rounder for image reading and document building.
- One-time purchase with no recurring subscription.
- Chats and files stay on your computer; only features you turn on, like the initial model download, touch the internet.
- Well suited to students working with PDFs, professionals handling sensitive files, and writers who want to draft offline.
The All-rounder model benefits from around 8GB of RAM for smooth performance, and a slower computer will still work, just at a slower pace when generating longer responses or processing documents.
Ease of setup and initial download requirements for offline/local alternatives
Getting a local assistant running takes a different kind of setup than opening a browser tab. With GreenCube, installation involves downloading the app, signing in once with a Google or Microsoft account to verify your license, and then choosing which model to download: Quick at roughly 2GB, or All-rounder at roughly 4.2GB. That download happens once, and after that the assistant works without an internet connection.
This is a meaningful trade compared to cloud tools like ChatGPT or Copilot, which need no download at all beyond a browser or a lightweight app. The one-time setup cost for a local tool buys you a program that keeps functioning on a slow connection, a flight, or a network with no signal. A Medium piece on local AI privacy points out that plenty of desktop AI apps still quietly use the internet for model downloads, analytics, or syncing, so it's worth checking exactly what a tool needs online and what it can run entirely without.
For readers who want a longer rundown of download-based assistants, our roundup of ChatGPT alternatives covers several more setup paths in detail.
Hardware requirements and performance considerations for local AI assistant options
A local AI assistant asks your computer to do work that a cloud tool normally offloads to a remote data center, so your hardware matters more than it would with ChatGPT or Bard. Lighter models, like GreenCube's Quick option built on Llama 3.2 3B, run fast on modest hardware since they stick to plain text. Heavier models that handle images and longer documents, like the All-rounder option built on Gemma 4 E4B, need more memory, generally around 8GB of RAM, to stay responsive.
The practical effect is simple: a newer computer with more RAM will answer faster and handle bigger documents more smoothly, while an older or lower-powered machine will still work but respond more slowly. Zapier's comparison of chatbot options notes that different tools suit different needs, and hardware fit is exactly the kind of practical detail that decides whether a local option feels fast or sluggish day to day. If you're on a slower laptop, the plain-text model is the more comfortable starting point, with the option to try the larger model later.
Verification and sign-in requirements across these alternatives
Most of these tools ask for an account before you can start chatting, and what that sign-in actually does varies a lot. With ChatGPT, Copilot, Google Bard, Jasper, YouChat, and Chatsonic, signing in typically creates an account on the provider's servers, and your conversations are generally processed and stored in the cloud as part of delivering the service.
GreenCube's sign-in works differently: a one-time Google or Microsoft login verifies your license, and nothing about your chats or documents passes through that sign-in. Once verified, the app runs offline, and your conversations never reach a server at all. For a closer look at how cloud providers handle chat data by default, our breakdown of ChatGPT's privacy practices walks through what gets stored and for how long.
Comparing image reading, document building, and multimodal features
Capabilities differ sharply across this list, and matching the tool to the task matters more than picking whichever name is most familiar.
| Tool | Best for | Access mode | Multimodal / document features | Pricing model |
|---|---|---|---|---|
| GreenCube | Privacy-first offline use | Local, offline | All-rounder model reads images, builds documents and study guides | One-time purchase |
| ChatGPT | General-purpose writing and plugins | Cloud | Text generation, broad plugin ecosystem | Free tier plus subscription |
| Copilot | Office productivity | Cloud, Microsoft 365 | Works inside Word, Excel, and Outlook documents | Free tier plus subscription |
| Google Bard | Google ecosystem users | Cloud, web | Integrates with Docs, Gmail, and Search | Free, with some gated features |
| Jasper | Marketing and content teams | Cloud, subscription | Copywriting templates and marketing tools | Subscription |
| YouChat | Quick web-aware answers | Cloud, web | Search-integrated chat responses | Free, with optional paid features |
| Chatsonic | Up-to-date content creation | Cloud, subscription | Web-context content generation | Subscription |
GreenCube's two-model setup is the clearest example of a trade-off built into the product itself: the Quick model keeps things fast but text-only, while the All-rounder model adds image reading and document building at the cost of needing more memory and running somewhat slower. Cloud tools like ChatGPT and Copilot don't ask you to make that choice, since their processing happens on remote hardware, but that convenience is exactly what you give up when you want your files to stay local. For a deeper technical comparison of these trade-offs, see our piece on local AI versus ChatGPT.
Where local and cloud assistants sit in the 2026 AI landscape
Cloud models still lead on raw capability. The newest reasoning, the widest plugin ecosystems, and the fastest-updating knowledge all live on remote servers right now, and that's unlikely to change soon. What's shifted is that local tools have become genuinely usable for everyday writing, reading, and document work, which means the choice is less about capability and more about what you're willing to trade for data staying on your own machine. Match the decision to your own priorities using the checklist above.

FAQ
What replaced Bing Chat?
Bing Chat was rebranded and folded into Microsoft Copilot, which now handles the same conversational assistant role inside Microsoft's products and on the web. Copilot keeps the Microsoft 365 integration that Bing Chat offered, built on top of a large language model paired with web data, according to PCMag's testing.
Which is the best free AI chat option?
ChatGPT, Google Bard, and YouChat all offer usable free tiers for general conversation and web-aware answers, according to Zapier's comparison of chatbot options. If privacy matters more than cost, a one-time local purchase like GreenCube avoids ongoing fees entirely while keeping your data off the cloud.
What shouldn't you share with a cloud-based AI chatbot?
Avoid typing passwords, financial account numbers, medical records, or other sensitive personal documents into a cloud chatbot unless you've confirmed how that provider stores and uses your data. A Medium article on local AI privacy notes that even tools marketed as private can still send some data online, so it's worth verifying before you share anything sensitive.
Is Bing Chat the same as ChatGPT?
No. Bing Chat, now part of Copilot, was built by Microsoft using a language model paired with web search and deep Microsoft 365 integration, while ChatGPT is OpenAI's own standalone product with its own apps and plugin ecosystem. Both rely on large language models, but they come from different companies with different integrations, as PCMag's reviews describe.
Do I need an internet connection to use a local AI assistant like GreenCube?
No, not for daily use. GreenCube downloads its chosen model once during setup and verifies your license with a one-time sign-in, and after that it works fully offline, with only optional features requiring a connection.
