Manta Presence: Balanced

Manta sits quietly while you chat. You set how much AI is okay for each task and it steps in only when you drift.

What is Manta

A Fitbit for your AI use

You already decide how much movement is enough. Manta does the same for thinking with AI. You set how much help is okay for each kind of task — writing, coding, learning, the rest. Then it sits in the chat and only steps in when you drift past the line you drew.

1

Set your intentions

Pick how much AI is okay for each task type — from “no AI” to “take the wheel”.

2

Gentle interventions

Nudges before warnings, warnings before blocks. Everything can be snoozed.

3

See your patterns

A dashboard that shows how your AI habits are trending — and improving.

How it works

It steps in only when you drift

Manta sits in the chat, reads each prompt in the moment, and only acts where you asked it to. Offloaded tasks pass through. Protected ones get a nudge — never a lecture.

1

It reads each prompt in the moment

Only in the chatbot tabs you chose. The prompt is sorted into a category — like “Writing · handed over to AI” — and the text is immediately discarded.

2

It checks the category against your settings

Each area is set as no AI, protected, or offloaded. Protected and no-AI areas are watched; offloaded ones pass through untouched. Your confidence and Manta’s presence setting decide how firmly it responds.

3

It steps in only when you drift

A gentle nudge at the composer, never a lecture. Every intervention can be snoozed, and each one is logged to your dashboard.

When it steps in

Four surfaces, lightest to firmest. Every one has a way through — and none of them ever sends your text anywhere.

The science

Cognitive offloading

A shopping list, a calendar, a calculator: using the world so your mind doesn’t have to. Psychologists call this cognitive offloading. It is ordinary, and often wise. The question with generative AI is not whether we offload — we always have — but whether we still do the thinking the skill depends on.

Offloading is a strategy, not a defect

Cognitive offloading is “the use of physical action to alter the information processing requirements of a task so as to reduce cognitive demand.” We choose between doing the work internally and handing it to the environment based on a metacognitive bet: how good am I at this, versus how good is the tool? When that bet is wrong — overconfidence in the model, or underconfidence in ourselves — we offload work we still needed to do, or fail to offload work the tool would have helped with. The literature’s point, and Manta’s: offloading itself is neutral. The risk is an unchecked handoff.

Unguarded genAI can help performance and hurt learning

A field experiment with nearly a thousand Turkish high-school mathematics students gave some of them GPT-4 during practice. Two interfaces: GPT Base, which behaved like ChatGPT, and GPT Tutor, which was prompted to give hints rather than answers. With the model in the room, scores jumped. On a later exam with no AI, students who had used GPT Base scored worse than classmates who never had it. They had used the model as a crutch — asking for solutions and copying them — and they did not notice the learning loss. The Tutor’s guardrails largely erased that harm.

Writing with an LLM, the brain does less of the work

In an EEG study of essay writing, people worked unaided, with a search engine, or with an LLM. Neural coupling was strongest in the unaided group and weakest in the LLM group. People who had used the model felt less ownership of the essays and recalled less of what they had “written.” In a later session, those who switched from the LLM to writing alone still looked under-engaged compared with people who had started unaided. This is a preprint with a modest sample — 54 people, 18 in the follow-up — so treat it as a signal, not a verdict. It points the same way as the classroom evidence: the tool can take the load, and the skill may not form.

Frequent AI use tracks with more offloading

A survey of 666 adults found that more frequent AI use was associated with lower critical-thinking scores, and that the link ran through self-reported cognitive offloading. Younger respondents reported more dependence. This is correlational — it does not prove that AI causes weaker thinking — but it matches the mechanism the experiments describe: the more the thinking is handed off, the less it is practised.

Manta’s bet sits on the classroom result: guardrails matter. You name which skills to keep. When a prompt looks like it is handing those over, Manta asks you to stay in the work — an attempt first, a question, a pause — the same kind of friction that kept Bastani’s Tutor from becoming a crutch. Offloaded tasks go through. You set the line.
