NoArk vs Manus

Both run AI agents that get real work done. Only one charges a flat $99.99/month for unlimited use — instead of a credit meter that can drain thousands a month.

Manus is a capable autonomous AI agent — but it runs on a credit meter, and heavy users routinely report burning $1,000–$5,000+ per month on add-on credit packs once a single complex task can cost 500–1,000 credits and a runaway loop can chew through 88,000 in one sitting. NoArk — Infinity Memory takes the opposite approach: a flat $99.99/month Diamond plan with unlimited agentic workflows, no credit anxiety, no sign-in, and every conversation kept on your own device. Here's the honest comparison.

The credit meter problem — and why a flat $99.99 changes the math

Manus's pricing is built around credits. The published tiers — $20 for 4,000 credits, $40 for 8,000, and $200 for 40,000 — look reasonable on paper, but the moment you actually use Manus the way it's marketed (as an autonomous agent that researches, writes, builds, and analyzes for hours), the meter runs hot. Users on Reddit consistently describe burning 40% of a monthly allocation in a single hour, exhausting the free 1,000 starter credits on their first request, and watching looping tasks consume 88,000 credits in one go. Once your monthly bucket is empty, the only way to keep working is to buy add-on credit packs, and that's where heavy agentic users routinely land at $1,000–$5,000+ per month.

NoArk's Diamond plan is a flat $99.99/month for unlimited agentic workflows. There's no credit balance to watch, no surprise drain, and no incentive to write smaller prompts to save tokens. Run one task or ten thousand — the price is the same. For anyone using AI agents seriously, the math isn't close.

Private by default — no account, nothing collected

Manus requires you to sign in, and your tasks and data are sent to the company's servers. NoArk takes the opposite path: there is no sign-in — no email, no phone number — and your conversations are stored only on your device and in your own iCloud, never warehoused on our servers and never used to train any model. Apple's official App Privacy label for NoArk reads “Data Not Collected”, the strictest there is. The work your agents do for you stays yours.

More than an agent: a full Apple super app

Manus is one thing — an autonomous agent in a browser tab. NoArk is a full Apple super app for iPhone, iPad, Mac, and Apple Vision: live global headlines with one-tap analysis, the Fiat Lux tab where you bring real questions to AI versions of history's wisest minds (Charlie Munger, Steve Jobs, Marcus Aurelius, and 40+ more), and 40+ ready-made workflows across markets, productivity, travel, education, and life admin — with an investing brain built by the team behind TradingTransformer, inspired by Claude Shannon's vision of AI stock-picking. All powered by many frontier models — Claude Fable, DeepSeek, Mistral, Kimi, and Gemini.
