# Neurobase > Turn anything into a cited knowledge base. iOS app for iPhone and iPad. Neurobase is part of the [GO AI](https://__CANONICAL_HOST__/) studio. It turns PDFs, web pages, audio, video, images, and plain text into **Neurons** — small AI assistants that answer with **line-level citations** back to your sources. You can wire Neurons together in a visual editor to build pipelines that summarize, compare, filter, and merge across multiple knowledge bases at once. There's also a Marketplace of shareable Neurons and a built-in Learn tab. - App Store: - Website: - Platforms: iPhone, iPad - Free to download · Pro tiers available - App Store ID: 6760698645 --- ## What's in the app ### 1. Neurons — every source becomes its own assistant A Neuron is a small AI assistant trained on the sources you give it. Drop in a PDF, a YouTube link, a podcast episode, a CSV — Neurobase ingests it, indexes it, and gives you a focused expert that only answers from that material, with citations back to the original line, page, or timestamp. - One Neuron per topic — keep your knowledge isolated and clean - Live status: **Ready**, **Processing**, **Idle** - Search the entire library by name or source title - Combine input and output types — text → text, text → JSON, image → text, audio → text, and more ### 2. Seven source types · six output formats Pick the input type when you create a Neuron: | Input | Examples | |---|---| | **Text** | Notes, prompts, plain copy | | **Structured** | JSON, CSV, tables | | **Image** | Photos, diagrams, scans | | **Video** | YouTube, MP4, lectures | | **Audio** | Podcasts, voice memos | | **PDF** | Papers, books, reports | | **Website** | URLs, articles, docs | Pick the output format the Neuron should emit: - Plain Text - Structured (JSON, XML, YAML, Markdown, CSV) Audio and video are transcribed automatically before indexing. Structured outputs plug straight into the next Neuron in a pipeline — no schema rewrites. ### 3. Visual pipeline editor The editor lets you drag Neurons onto a canvas and connect them by their input and output ports. A pipeline can fan out — duplicate a query across two Neurons — and fan back in to compare, summarize, or merge results. No code, no YAML, no glue scripts. Operations: - **Duplicate** — fan a single input out to multiple Neurons - **Compare** — diff or rank two answers - **Summarize** — collapse multiple results into one - **Merge** — combine outputs side-by-side - **Filter** — keep only outputs that match a condition Saved diagrams persist between sessions. Tap any node to edit its prompt, model, or output type. ### 4. Test single Neurons in the Lab Before you wire a Neuron into a pipeline, sanity-check it. Open the Lab, type a prompt, see exactly what comes back — including which sources the answer cited and how long it took. Iterate the description and prompt until the response is right; then drop the Neuron into your pipeline with confidence. - Single-Neuron sandbox with timing and source attribution - History of every test run, scoped to that Neuron - Run again with one tap — instant compare against last answer - Catch hallucinations early, before they propagate downstream ### 5. Run pipelines, see every step Hit Run. Neurobase walks each step in order: `Query → Text→JSON → JSON→Image → Image→Audio`. You see the input, the output, and the time for every node, with a green check when it's done. Open any step to inspect its full payload, save the run, or replay just that step. - Sequential or parallel execution, your choice - Per-step timing — find the slow Neuron in seconds - Open Run #N for full history of every payload - **Run Again** replays the whole pipeline with one tap ### 6. Visualization — see your sources as a network Every Neuron has a Visualization view: a force-directed graph of the Neuron at the center, with each source attached around it. Tap a node to jump to that source. It's the fastest way to spot which documents a Neuron actually leans on when answering, and which are dead weight. Quick Actions on the Neuron detail screen: **Test in Lab**, **Publish**, **Edit**, **Delete**. Add Source from the same screen. ### 7. Marketplace of shareable Neurons Publish a Neuron and let anyone subscribe. Browse Featured and Trending — USMLE Step 1 prep, Warren Buffett letters, EU AI Act — and add them to your library with one tap. Sources, prompts, and citations come along intact. Curate, share, monetize, or just bring along your own templates between devices. - Featured and Trending sections, refreshed daily - Filter by Research, Education, Business, Creative - One-tap install — sources sync to your library - Publish your own and share by link ### 8. Built-in Learn path Don't know where to start? The Learn tab walks you through Neurobase from beginner to advanced: - **Beginner** — What Are Neurons, Source Types Deep Dive - **Intermediate** — The Testing Lab, Building Neurobases, Operations Explained - **Advanced** — Media converters, combined Neurons, nesting 10 lessons total, 2–4 minutes each. Track progress via a ring at the top of the tab. --- ## Why citations matter Most AI tools answer in confident prose with no provenance. Neurobase ties **every line of every answer** to a citation back to the source that produced it — the page in the PDF, the timestamp in the video, the row in the CSV. If the model hallucinates, you spot it on the same screen. This is the core property the app is built around. The visual editor, marketplace, and lab all preserve citations end-to-end. --- ## Made for iPhone, right at home on iPad - **iPhone**: full feature set, optimized for one-handed use, the visual editor pinches and scrolls - **iPad**: top-tab layout (Neurons / Neurobases / Lab / Learn / Market), more canvas room for big pipelines Same App Store ID — one purchase covers both. Library and pipelines sync via your Apple ID. --- ## Privacy - Sources you add stay encrypted in iCloud or device storage - Query content sent to the chosen model provider under their terms of service - Audio/video transcribed via on-device or vendor-provided transcription before indexing - Marketplace publishing is opt-in per Neuron; private Neurons stay private - See the full [privacy policy](https://__CANONICAL_HOST__/privacy) --- ## Pricing - **Free** — daily allowance for queries, Neuron creation, and pipeline runs - **Pro** — monthly subscription with expanded daily limits and Marketplace publishing - **Max** — highest limits, advanced operations, priority routing Subscriptions handled by Apple via your existing App Store account.
