I tried the 6 best Inflection AI alternatives for 2025

I’ll be honest, I was a big fan of Inflection AI’s Pi. It felt different. Less like a search bar and more like a smart, supportive friend you could bounce ideas off of. It just got the whole human-like conversation thing in a way other chatbots didn’t, so it’s easy to see why it built such a loyal following.

But with the recent news that Microsoft is basically absorbing the team and tech, a lot of us are left wondering what’s next for Pi. That uncertainty sent me and plenty of others on a hunt for the best Inflection AI alternatives.

So, I rolled up my sleeves and spent some serious time with the top conversational AI tools out there. My goal was to find solid replacements for different needs, whether you’re looking for a personal creative partner, a fact-checking research assistant, or a workhorse to help run your business. Here’s the rundown of what I learned.

What made Pi special and why people seek Inflection AI alternatives

Inflection AI designed Pi (which stands for Personal Intelligence) with a pretty unique goal: to be emotionally smart. While everyone else was in a race to build the fastest or most knowledgeable AI, Pi was built to be the kindest. It was made for supportive, natural back-and-forths, not just for firing off answers to quick questions.

This made it the perfect sounding board. You could use it to brainstorm a new project, practice a difficult conversation, or just talk about your day. Pi set a high bar for what an empathetic AI could be, and that’s the standard I used to measure everything else.

How I picked the top Inflection AI alternatives

To make this a fair fight, I judged each tool on a few key things that made Pi great, while also keeping in mind what people actually need from a tool day-to-day.

• Conversational Quality: How natural is the chat? Does it feel like you’re talking to a person who remembers what you said five minutes ago, or is it a goldfish starting fresh with every prompt?

• Core Use Case: What is this thing really for? Is it a creative writer, a deep researcher, a general productivity tool, or something specialized for business?

• Personalization and Control: Can you tweak its personality? Can you teach it from your own documents or tell it how to act?

• Ease of Use & Pricing: Is it easy to get started? Is the price tag fair and easy to understand, or are you going to get a surprise bill?

The 6 best Inflection AI alternatives in 2025

After spending a good chunk of time with each platform, here’s my detailed breakdown of the top contenders.

1. eesel AI

If you ever looked at Pi and thought, "I wish this could run my company’s customer support," then you should check out eesel AI. While Pi was made for personal chats, eesel AI takes that conversational magic and puts it to work in a professional setting. It creates an AI agent that learns from your company’s knowledge and works right inside the tools you already use.

It’s built for teams that need an AI that can actually do things, not just chat.

• Unifies Your Knowledge: Unlike a generic AI that knows a little about everything, eesel AI connects to your company’s brain. It learns from your helpdesk history in tools like Zendesk or Freshdesk, your internal guides on Confluence, and your documents in Google Docs. The result is hyper-relevant answers that sound like they came from one of your own team members.

• Total Control & Customization: This is where it really pulls ahead for business use. You can define the AI’s persona, set its tone of voice, and give it specific jobs. It can answer customer questions, sort incoming tickets, look up order details from Shopify, and pass tricky issues to a human, all without ever leaving your helpdesk.

• Go Live in Minutes: The setup is surprisingly straightforward. You can connect your knowledge sources, set up your AI agent, and launch it without having to talk to a salesperson. That’s a breath of fresh air compared to most enterprise AI tools that take months to get running.

Pros:

• Learns from your real business data, so responses are accurate and on-brand.

• You can customize everything from its personality to the actions it can take.

• It lets you test its performance on your past support tickets, so you can see how it’ll do without any risk.

Cons:

• It’s built for business use cases like customer service and internal IT support, not casual chats about your weekend plans.

• It’s a premium tool designed for professional teams, so there’s no free-forever plan.

Pricing:

eesel AI’s pricing is based on a set number of monthly AI interactions (a reply or an action), which means no surprise bills.

• Team Plan: $299/month ($239/month if billed annually) for up to 3 bots and 1,000 interactions.

• Business Plan: $799/month ($639/month if billed annually) for unlimited bots, 3,000 interactions, and unlocks key features like training on past tickets and advanced AI actions.

• Custom Plan: Available for teams with unique needs and a higher volume of interactions.

2. Claude

For anyone who loved Pi’s nuanced, almost poetic way of talking, Claude is probably the closest spiritual successor. It was developed by Anthropic with a big focus on AI safety, and it’s fantastic at producing thoughtful, well-reasoned, and creative text.

This is the AI I go to when I need a writing partner, not just an answer machine. It’s especially good at summarizing dense documents, drafting creative content, and explaining complex technical stuff clearly. Its giant context window is a huge plus, letting it remember details from long conversations or entire documents. That’s a lifesaver for writers and researchers.

Pros:

• Great for creating and analyzing long-form content.

• Has a strong focus on generating ethical and safe responses.

• The free tier is generous, making it easy for anyone to give it a spin.

Cons:

• The free version isn’t hooked up to the live internet, so its knowledge has a cutoff date.

• Sometimes it can be a little too cautious or wordy because it prioritizes safety above all else.

Pricing:

• Free: A solid free version is available for everyone.

• Pro: $20/month ($17/month if billed annually) for more usage and access to the latest models.

• Team: $30/user/month ($25/user/month if billed annually) for collaborative features, with a minimum of 5 users.

For detailed information, check Claude’s official pricing page.

3. Google Gemini

Gemini is Google’s AI heavyweight, and it’s the top pick for anyone who needs an assistant that’s plugged directly into the web and a bunch of productivity tools. Its biggest strength is its direct line to Google Search, meaning it can pull real-time information and tell you where it got it.

But where Gemini really flexes is its ability to handle more than just text. It understands and processes images, audio, and code, making it incredibly versatile. It can also connect to Google Workspace, so you can ask it to summarize a long email chain in Gmail or help you write a report in Docs. It’s a practical, powerful tool for getting things done.

Pros:

• Amazing for real-time information and web research with sources.

• Strong multi-format skills (text, images, audio, code).

• Connects smoothly with the Google ecosystem (Workspace, Search).

Cons:

• Its conversational style can feel a little less creative or natural than Claude’s.

• You need a Google account to use it, which is a barrier for some.

Pricing:

• Free: A powerful version of Gemini is free for anyone with a Google account.

• Gemini Advanced: Unlocks more powerful models and features through a Google One AI Premium plan, starting at $19.99/month.

4. ChatGPT

ChatGPT is the tool that put AI on the map, and it’s still one of the most powerful and flexible options out there. It might not have Pi’s specific focus on empathy, but its sheer range of skills makes it a strong alternative for almost anything you can imagine.

Powered by OpenAI’s latest models like GPT-4o, ChatGPT can write code, draft marketing emails, plan your trip, and a whole lot more. Its biggest advantage is the massive ecosystem around it. The GPT Store has thousands of custom chatbots built for specific tasks, from designing logos to analyzing research papers. Paid plans also give you web browsing, data analysis, and image creation with DALL-E, turning it into a true AI Swiss Army knife.

Pros:

• Incredibly versatile and capable of handling a huge range of tasks.

• A giant ecosystem of custom GPTs and other integrations.

• Always being updated with the newest AI bells and whistles.

Cons:

• The free version uses an older model and can get sluggish during busy times.

• It lacks that specialized, supportive tone that made Pi feel special.

Pricing:

• Free: Gives you access to a base model that’s great for everyday tasks.

• Plus: $20/month for access to more advanced models like GPT-4o, faster responses, and tools like DALL-E and data analysis.

• Pro: $200/month for unlimited access to the highest-tier models.

• Business: $30/user/month ($25/user/month annually) for a secure workspace with admin controls.

5. Perplexity AI

If you want an AI that acts more like a super-smart research librarian than a friendly chatterbox, Perplexity AI is for you. It calls itself an "answer engine," and that’s a perfect description. It’s built to give you direct, factual answers and, most importantly, to show you its work.

For every response, Perplexity gives you citations with links to the original web pages. This is a huge deal for anyone who needs to verify information, like students, journalists, or professional researchers. You can even use its "Focus" feature to limit your search to specific places like academic journals, YouTube, or Reddit. It’s less about the chat and more about the facts.

Pros:

• Provides citations and links to sources for every answer.

• Excellent for getting quick, verifiable facts.

• The interface is clean, ad-free, and gets straight to the point.

Cons:

• It’s not designed for creative writing or open-ended, empathetic conversations.

• The back-and-forth can feel a bit transactional, like you’re just getting information.

Pricing:

• Free: A solid free version is available for general use.

• Pro: $20/month for unlimited Pro searches, file uploads, and access to more advanced AI models like GPT-4o and Claude 3.5.

For detailed information, check Perplexity’s pricing page.

6. Poe by Quora

Poe is like an all-access pass to the world of AI chatbots. Instead of making you pick just one, Poe gives you a single place to talk to a whole bunch of them, including models from OpenAI (ChatGPT), Anthropic (Claude), Google (Gemini), and others.

This makes it the perfect playground for AI nerds or anyone who wants to see how different models tackle the same problem. You can even create your own custom bots by giving them specific instructions and prompts. If you like to experiment and want to stay on the cutting edge without juggling a dozen different subscriptions, Poe is a great choice.

Pros:

• Access to many of the world’s top AI models in one subscription.

• You can create and share your own custom chatbots.

• A simple, unified interface makes it easy to play around.

Cons:

• The free version has pretty tight daily message limits, strongly nudging you to subscribe.

• It can feel like a "jack of all trades, master of none" if you need to do deep, specialized work.

Pricing:

• Free: A limited free tier is available with daily message caps.

• Subscription: $19.99/month or $199.99/year for higher message limits and access to the best models.

For detailed information, see Poe’s subscription pricing.

What to consider when choosing between Inflection AI alternatives

Finding the right tool is about more than just how good the conversation is. Here are a couple of other key things to chew on.

• Personal Use vs. Business Use: If you just need a brainstorming buddy or a creative muse, a tool like Claude or ChatGPT is a great fit. But if you’re trying to automate parts of your business or handle sensitive customer data, you need something built for professionals. That means thinking about security, control, and how well it plays with the tools you already use.

• Data Privacy and Security: Let’s talk about the elephant in the room. Most free, consumer AIs use your conversations to train their models. For personal musings, that might be fine. For your business, it’s a non-starter. You need a platform like eesel AI that guarantees in its contracts that your data stays private and is never used to train other models.

• Integration with Your Tools: A personal AI can live happily in a single browser tab. A business AI needs to be where your team works. Before you commit, check if the tool can connect to your helpdesk, CRM, internal docs, and chat apps like Slack.

The future is conversational: Final thoughts on Inflection AI alternatives

Inflection’s Pi showed us just how powerful and just plain nice a natural AI conversation could be. While its own future is up in the air, the good news is that the rest of the AI world was paying attention.

As we’ve seen, the best Inflection AI alternatives really depend on what you’re trying to do. There are amazing options out there for personal creativity (Claude), lightning-fast research (Perplexity), and all-around usefulness (ChatGPT).

But the big shift isn’t just about having better chats; it’s about using that conversational power to solve real problems. Generic chatbots just don’t cut it in a business environment because they don’t know your company, you can’t control them, and they don’t connect with your workflows.

That’s where a specialized platform changes the game. If you’re ready to move beyond simple Q&A and put a knowledgeable AI agent to work for your support teams, a dedicated platform is the clear next step.
