About

Neutropic

Features
Read full description

Neutropic is an AI research agent for neuroscience, psychology, behavioral science and HCI. One question carries you from the literature to experiment design, data analysis and a written manuscript, and every result is traced to its evidence. โ–  Literature reviews with every claim cited Search several scholarly databases at once and get a structured synthesis with verified [n] citations on every sentence โ€” including where studies disagree and what is still unknown. โ–  Study designs you can defend Compare hypotheses by novelty, plausibility and testability, and get a design document with a protocol flow and a power curve. Each design choice shows how related studies handled it. โ–  Statistics with assumptions checked twice The method is chosen from your design and data, and results report effect sizes, confidence intervals and power โ€” not just p-values. An independent review agent checks the analysis again. โ–  Multimodal human data Work with surveys and experiment data (CSV, Excel) as well as EEG, speech and video (facial expression, posture). Record audio or capture video right in the app and ask for an analysis. โ–  Editable figures and manuscripts Create editable vector charts and scientific illustrations in a consistent style, and draft manuscripts whose methods and results come from your real analyses. Run a manuscript check or a mock peer review before you submit. โ–  Built for your phone Hand off a long task and get on with your day: a notification arrives when it finishes, and tapping it opens the result. Attach files from Files or Photos, and continue the projects and chats you started on the web. โ–  Subscriptions (optional) Keep using the free plan, or subscribe in the app to Lite, Pro or Max (monthly or yearly) for a larger token allowance. Prices are shown on the plan screen. Subscriptions are charged to your Apple Account and renew automatically for the same period and price unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in Settings โ€บ Apple Account โ€บ Subscriptions. Your subscription also applies to the Neutropic web app. Sign in with your Neutropic account (email, Google or Apple).
