AI Agents
FOUR AI HELPERS, SIDE BY SIDE
What each app does — and what each plan actually costs
| App | What It Does | What It Costs |
|---|---|---|
| 💬 Buzz | Feels just like a group chat: the AI sits right in the chat room with you and your friends instead of a private, lonely window. Tag it like a normal person (e.g., @helper) to give it a job. |
Basic: $0 — free forever Private: the software itself is free, but a company that wants a fully private, locked-down setup pays for its own secure online storage |
| 🤖 Manus AI | An independent helper that does the internet digging for you. Give it a big goal — “chart real-estate prices” or “write a short presentation” — and it browses the web and makes the actual files while you sit back and watch. |
Free: $0 — 1 simple task at a time Starter: $20/month — multiple tasks at once Heavy: $40/month — much larger projects Pro: $200/month — a massive amount of monthly work |
| 🧠 Vellum AI | A personal assistant that remembers who you are. Instead of forgetting every chat the moment you close it, it builds long-term memory of your writing styles, personal files, and ongoing projects. |
Free: $0 — slow speed; pay for any extra computer time Mighty: $30/month — generous prepaid computer time Super: $100/month — faster speed, more features Ultra: $200/month — top speed + personal help support |
| 🔎 Perplexity Max | The ultimate internet researcher for big reports where you cannot afford mistakes: it searches dozens of places at once and gives a clickable link for every detail, so you can check its work. |
Max: $200/month flat — unlocks the entire smart-search sandbox with unlimited access to the strongest research features |
