Modalities — NotebookLM Wins

Modalities: Julius AI compared with NotebookLM
Feature	Julius AI	NotebookLM
Text Input	Yes. Chat interface over your data.	Yes, requires free plan. Chat with a notebook to get answers grounded in your uploaded sources.
Image Upload / Vision	Yes. Upload charts and images for interpretation.	Yes, requires free plan. Help documents Gemini Notebook working across text, graphs, and images, and accepting Google Slides and other visual sources.
Image Generation	No. Produces charts from data rather than generative artwork.	Yes, requires plus plan. Studio can produce infographics and slide decks from sources. Google AI Plus/Pro raise those generation limits; it is not a general art model.
Voice Mode	No. No voice interface.	Partial. Audio Overviews have an Interactive Mode (beta, English) where you can join the hosts. That is not a full duplex voice chat with the notebook.
Video Understanding	No. Does not analyse existing video.	Yes, requires free plan. Public YouTube URLs are a supported source type. Video Overviews are a separate studio output with plan limits.
Video Generation	No. Not a video generation product.	No. Not a video generation product.
File Upload (PDF, DOCX)	Yes. Upload CSV, Excel, and other data files for analysis.	Yes, requires free plan. PDFs, Google Docs, Google Slides, ePub, copied text, and Drive sources are documented. Pro raises the per-notebook source cap (up to 300).
Code Execution	Yes. Writes and runs Python to analyse data and plot charts.	Yes, requires pro plan. A secure cloud computer can write and run code in the notebook. Google says Ultra and some Workspace tiers have it now; Pro on the web is rolling out.
Audio Input	No. No audio input.	Yes, requires free plan. Audio files are a documented source type. Audio Overviews are generated output, not just playback of uploads.
Canvas / Artifact Editor	Partial. Notebook-style output panel alongside the chat.	Yes, requires free plan. Studio transforms sources into study guides, briefings, mind maps, slides, and reports — a dedicated output canvas beside chat.
Screen Sharing / Computer Use	No. No computer-use capability.	No. No computer-use / screen-control product. You add sources, you do not hand over the desktop.

Memory & Context — Tie

Memory & Context: Julius AI compared with NotebookLM
Feature	Julius AI	NotebookLM
Persistent Memory	Unknown. Not confirmed either way.	Partial. Sources and chats persist inside a notebook. There is no global cross-notebook user-memory profile like ChatGPT Memory.
Large Context Window	Partial. Bound by the underlying model; not published as a headline figure.	Unknown. Google publishes source-count limits, not a token window for Gemini Notebook chat.
Custom Instructions	Unknown. Not confirmed either way.	Unknown. A global custom-instructions setting was not confirmed in the help articles checked.
Conversation History	Yes. Chat threads are saved and can be resumed.	Yes, requires free plan. Notebooks persist. Cross-app sync keeps the same notebook in the Gemini app and the standalone product.

Integrations — NotebookLM Wins

Integrations: Julius AI compared with NotebookLM
Feature	Julius AI	NotebookLM
Web Search / Browsing	Unknown. Not confirmed either way.	Yes, requires free plan. Discover sources via Fast Research (web or Drive) and Gemini Deep Research inside Notebook, which can browse many sites and import the report.
Plugins / Extensions	No. No plugin marketplace.	No. No third-party plugin marketplace. Sources and Google apps are the integration surface.
API Access	Unknown. Not confirmed either way.	No. Gemini Notebook is a consumer/Workspace product. There is no public NotebookLM generate API documented in the help center.
Zapier Integration	Unknown. Not confirmed either way.	Unknown. No first-party Gemini Notebook Zapier app was checked.
Custom GPTs / Bots	No. No agent or bot builder.	No. You do not publish Custom GPT-style bots. A notebook is a private (or shared) source collection.
Real-time Collaboration	Unknown. Not confirmed either way.	Partial. Notebooks can be shared. Upgrade help says sharing does not change another collaborator’s source limit. Live multiplayer cursor editing is not documented.
Live Social Data Integration		No. Not a live social-firehose product. You can add public web/YouTube URLs as sources.
Live Citation Mapping		Yes, requires free plan. Chat answers include in-line citations back to the notebook sources.

Developer — Tie

Developer: Julius AI compared with NotebookLM
Feature	Julius AI	NotebookLM
Function Calling	No. No tool-calling interface.	Partial. The secure cloud computer can produce files (CSV, JSON, code). That is not a developer tool-calling API for third-party functions.
Streaming Responses	No. Generations are returned complete, not streamed token by token.	Unknown. Chat streams in the UI, but token streaming is not documented as a product guarantee.
Fine-Tuning	No. No custom model training.	No. You ground on sources. There is no custom-weight training product.
Embeddings API	No. No embeddings endpoint.	No. Not an embeddings API. Retrieval stays inside the notebook.
Structured Output (JSON)	No. Not a language model, so this does not apply.	Partial. Cloud-computer outputs can include CSV and JSON. Everyday chat is cited prose, not a JSON-schema API.
Reasoning / Thinking Mode	Partial. Inherits reasoning from the underlying frontier models it routes to.	Unknown. Overlapping columns disagreed (yes vs partial); left unverified rather than copying a no.
Local Execution		No. The new “cloud computer” is hosted by Google, not a local runtime.
Open Weights		No. Closed Gemini models.
Multi-Agent Orchestration		Partial. Deep Research is an agentic researcher. It is not a general multi-agent SDK.
