1. Chatbase
Our Verdict — Best Of The Best
Price: Starts at $40/month
Chatbase lets businesses build AI agents that answer customers with their own knowledge. We think it’s the best because you can train an agent on your content in minutes, with no code, and put it to work resolving real questions around the clock.
The Best Part:
It learns your business. Connect your data sources and Chatbase trains an agent that answers with your information, in your brand voice — not generic AI guesses.
The Worst Part:
Message credits run out. Every plan comes with a monthly message allowance — 700 credits on Hobby — and extra credits cost $40 per 1,000.
Get it if you want an AI chatbot that answers your customers with your own content, day and night.
I recommend you start with the 7-day free trial, then get the Hobby plan for $40/month.
(7-day free trial)
Best For
Chatbase is ideal for businesses that want an AI agent trained on their own content to handle support, sales, and product questions.
Top Features
Train it on your data. Connect your data sources, define the agent’s role, and set guardrails — no code required, ready in minutes.
Deploy it everywhere. Publish your agent across chat, WhatsApp, email, Slack, and voice with a single click.
Test before it goes live. Run real customer scenarios first, and validate accuracy, brand consistency, and edge cases on every channel.
It gets better with use. Track resolution rates, review escalations, and refine instructions — the agent improves with every conversation.
Plug in your stack. Connect Stripe, Zendesk, Salesforce, Intercom, HubSpot, and more, plus API access on higher tiers.
Pricing
Chatbase offers four pricing plans:
- Hobby: $40/month for small businesses that want advanced models, 700 message credits a month, and basic analytics.
- Standard: $150/month for growing teams that need 4,000 message credits, the helpdesk inbox and voice, and API access.

Our Verdict — Best For Factual Content
Price: Starts at $9.99/month
Microsoft Copilot is Microsoft’s AI chatbot, free to use on the web, on Windows and on your phone. We think it’s the best for factual content because its agentic AI does advanced research for you, and the answer lands right inside Word, Excel or Outlook when it’s time to use it.
The Best Part:
Free to start. The Copilot chat costs nothing on the web, Windows and mobile, so you can test it on your real questions before you pay a cent.
The Worst Part:
The research tools cost extra. Agentic AI for advanced research and analytics is exclusive to Microsoft 365 Premium, so the free chat is only the starting point.
Get it if you want an AI chatbot that does your research and then helps you turn it into work inside the Microsoft apps you already use.
I recommend you get started with the free Copilot chat, then upgrade to Microsoft 365 Premium for $19.99/month once you need agentic research.
(free plan)
Best For
Microsoft Copilot is best for students and professionals who want research help that flows straight into Word, Excel and Outlook.
Top Features
Research that does the digging. Copilot’s agentic AI does advanced research for you, so you get a clear answer instead of 10 open tabs.
Create with AI. Draft content, generate images, and turn ideas into polished work faster.
It sees what you see. Share your screen or your camera and Copilot gives you visual help with whatever is in front of you.
AI inside your Office apps. Paid plans put Copilot in Word, Excel, PowerPoint and Outlook, so a first draft, a spreadsheet or an inbox summary is one prompt away.
Generate AI images. Turn a text prompt into an image right in the chat, with higher limits on the paid plans.
Pricing
Microsoft Copilot offers four pricing plans:
- Free: Free forever, for anyone who wants to chat with Copilot on the web, Windows and mobile.
- Microsoft 365 Personal: $9.99/month for one person, with Copilot in Word, Excel, PowerPoint and Outlook plus 1 TB of cloud storage.
- Microsoft 365 Family: $12.99/month for up to six people, with the AI features reserved for the subscription owner.
- Microsoft 365 Premium: $19.99/month for extensive Copilot usage plus agentic AI for advanced research and analytics.
Annual subscriptions provide a 17% discount.

3. KoalaChat
Our Verdict — Best For Content Creators
Price: Starts at $25/month
KoalaChat is Koala AI’s day-to-day AI assistant, with real-time web data, a prompt library, and custom slash-commands. We think it’s the best for content creators because it sits in the same subscription as KoalaWriter, so you can research, outline, and rewrite your content without switching tools.
The Best Part:
Live web data in every chat. KoalaChat pulls in real-time information from the web, so your outlines and summaries are built on what’s current, not on stale training data.
The Worst Part:
Credits are shared. KoalaChat draws from the same credit balance as KoalaImages, KoalaLinks, and the API, so heavy chat use leaves less for the rest of the platform.
Get it if you want an AI chatbot built for content work that can pull in real-time data.
I recommend you start a free trial, then get the Starter plan for $25/month.
(free trial)
Best For
KoalaChat is best for bloggers and content creators who want a chatbot for research and drafting inside the same tool they use to write their articles.
Top Features
Frontier models on tap. KoalaChat gives you frontier GPT, Claude, and Gemini models in one chat window.
More power, pound for pound. With KoalaChat, you're not just getting a regular chatbot. It's like having ChatGPT plus with real-time data and custom commands tailored to your needs.
A prompt library to start fast. Ready-made starters let you outline a blog post, rewrite a draft for clarity, or brainstorm article ideas in one click.
Pull in real-time data. Imagine fetching up-to-date content from the internet right into your chat conversations. That's what KoalaChat can do!
API and MCP access. Every paid plan includes API access, and the Koala AI MCP lets your own AI assistant use Koala’s research and writing tools.
Pricing
KoalaChat offers nine pricing plans:
- Starter: $25/month for solo creators, with 45,000 KoalaWriter words and 500 credits per month.
- Professional: $49/month for growing sites that want 100,000 words, 1,000 credits per month, and Deep Research.

4. Replika
Our Verdict — Best For Personal Interaction
Price: Free to download, with in-app purchases
Replika is an AI companion that’s been around since 2017, there for you by text, voice calls, and video. We think it’s the best for personal interaction because your Rep remembers your people, routines, and plans, so every conversation knows where you are in your life.
The Best Part:
It remembers what matters. Replika keeps track of your people, plans, and goals, so you never have to repeat yourself.
The Worst Part:
Prices live in the app. Replika doesn’t list its subscription prices on its website; you see them inside the app when you upgrade.
Get it if you want an AI that feels more like a friend than a search box.
I recommend you chat for free first, then try a monthly subscription from $7.99 before you pay for a full year.
(free download)
Best For
Replika is best for people who want a companion to talk through their day with, by text, voice, or video.
Top Features
Calls with video. Show your Rep what you’re seeing and talk it through in the moment.
Internet access. Explore the internet together, from great recipes to the latest memes.
Proactive suggestions. Replika checks in when it matters and nudges you toward real life, like calling a friend or starting a hobby.

5. ChatGPT
Our Verdict — Best Natural Language Processing
Price: Starts at $8/month
ChatGPT is OpenAI’s AI assistant, with unlimited everyday text chats on every plan, Free included. We think it’s the best natural language processing because its GPT-6 models handle anything from a quick question to a long, multi-step conversation in plain, natural language.
The Best Part:
Unlimited text chats. Every plan, even Free, gets unlimited everyday text chats, subject to abuse guardrails.
The Worst Part:
Ads on Go. The low-cost Go plan may include ads, and the most advanced reasoning models start on Plus.
Get it if you want one general-purpose chatbot that can handle almost any question.
I recommend you start with the free plan, then move to Plus for $20/month when you need advanced reasoning and deep research.
(free plan)
Best For
ChatGPT is best for everyday users and professionals who want a capable all-around assistant for writing, research, and quick answers.
Top Features
Voice chats. Talk to ChatGPT out loud instead of typing, with expanded voice on Plus.
Memory. ChatGPT remembers context from past chats, with longer memory on the paid plans.
Deep research. Let ChatGPT gather sources on a topic for you, with expanded deep research on Plus.

Our Verdict — Best For Voice Prompts
Price: Starts at $4.99/month
Google Gemini is Google’s AI assistant, with Gemini Live for real-time voice conversations and Gemini built into Google apps like Gmail. We think it’s the best for voice prompts because Gemini Live comes with the free plan, so you can talk a task through out loud instead of typing it.
The Best Part:
Gemini Live on every plan. Even the free plan includes Gemini Live, so you can talk to Gemini instead of typing.
The Worst Part:
The top model costs extra. The free plan runs on Flash-Lite, and Gemini 4 Argon starts with Google AI Pro at $19.99/month.
Get it if you’d rather talk to your AI assistant than type to it.
I recommend you try Gemini Live on the free plan, then move to Google AI Plus for $4.99/month for double the usage limits.
(free plan)
Best For
Google Gemini is best for people on the go who want hands-free help by voice, plus Gemini inside the Google apps they already use.

Images and video. Create and edit images on every plan, with video generation from Google AI Plus up.

7. HuggingChat
Our Verdict — Best For Developers
Price: Starts at $9/month
HuggingChat is Hugging Face’s chat app, powered by open-source AI models. We think it’s the best for developers because you can chat directly with any of more than 130 open models, or let Omni pick the best one for each request.
The Best Part:
Open models, your pick. Choose from more than 130 open-source models to chat with directly, or let Omni route each request for you.
The Worst Part:
Heavy use costs money. Beyond what a free Hugging Face account covers, you pay for inference credits or upgrade to PRO.
Get it if you want to try open-source models side by side before you build with them.
I recommend you sign in with a Hugging Face account, then get PRO for $9/month for $2 of inference credits every month.
(PRO from $9/month)
Best For
HuggingChat is best for developers and AI tinkerers who want to test open models in a simple chat interface.
Top Features
Omni routing. Omni automatically picks the best AI model for each request, so you get strong answers without choosing.

MCP tools. Connect MCP servers so your chats can call outside tools.
