What are the best AI tools for business that *actually* work?

What’s your recommendation on the best AI tools for small business?

I don’t need another app to cover just one thing like market research, coding, marketing, etc. Wasted enough money with different subscriptions that can all essentially be one app. 

My main problem: We need to use it with many teams, so sharing, collab, and management features are a must. Most AI tools right now are standalone – employees access cool LLMs, but I need to see how AI is used, optimize budget, share chats. 

Best AI tools for business I saw people recommending: 

1. ChatGPT – a classic. We tried the Enterprise package, just too expensive for what we get. Marketing likes to use GPT, Devs ask for Claude. Plus, the minimum seat requirement is too big for our small business. 
2. Portkey – seems to be the best option for devs, with Gateway, Observability, Guardrails, Governance and Prompt Management. But for other non-tech teams, that’s too complex – we’ll need another AI productivity tool, but we’re trying to minimize budget and have everything in one place.
3. Perplexity – after I tested it, it’s definitely the best AI tool for business productivity, but no idea how to integrate it in a team, like sharing files and working on projects together.
4. nexos.ai – still new in the market and under the radar, but covers all the productivity features + more dev tools, orchestration, API. Also noticed pretty advanced observability. Recent Assistants feature is sharable and fully customizable, and we’d get access to multiple LLMs, not just one.

I’m thinking of going with nexos first and testing the free trial. What do you think?
