Gamma vs NotebookLM
A feature-by-feature comparison of Gamma and NotebookLM across 7 capability categories.
Modalities — NotebookLM Wins
| Feature | Gamma | NotebookLM |
|---|---|---|
Text Input | Yes | Yes, requires free plan. Chat with a notebook to get answers grounded in your uploaded sources. |
Image Upload / Vision | Yes | Yes, requires free plan. Help documents Gemini Notebook working across text, graphs, and images, and accepting Google Slides and other visual sources. |
Image Generation | Yes | 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 | 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 | 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 | 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 | No | 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 | Yes, requires free plan. Audio files are a documented source type. Audio Overviews are generated output, not just playback of uploads. |
Canvas / Artifact Editor | Yes | 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. No computer-use / screen-control product. You add sources, you do not hand over the desktop. |
Memory & Context — Tie
| Feature | Gamma | NotebookLM |
|---|---|---|
Persistent Memory | Partial. Remembers brand and theme settings across decks, not conversational facts. | Partial. Sources and chats persist inside a notebook. There is no global cross-notebook user-memory profile like ChatGPT Memory. |
Large Context Window | No | Unknown. Google publishes source-count limits, not a token window for Gemini Notebook chat. |
Custom Instructions | No | Unknown. A global custom-instructions setting was not confirmed in the help articles checked. |
Conversation History | Yes | Yes, requires free plan. Notebooks persist. Cross-app sync keeps the same notebook in the Gemini app and the standalone product. |
Integrations — Tie
| Feature | Gamma | NotebookLM |
|---|---|---|
Web Search / Browsing | Yes | 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. No third-party plugin marketplace. Sources and Google apps are the integration surface. |
API Access | Paid Only | No. Gemini Notebook is a consumer/Workspace product. There is no public NotebookLM generate API documented in the help center. |
Zapier Integration | No | Unknown. No first-party Gemini Notebook Zapier app was checked. |
Custom GPTs / Bots | No | No. You do not publish Custom GPT-style bots. A notebook is a private (or shared) source collection. |
Real-time Collaboration | Yes | 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 — Gamma Wins
| Feature | Gamma | NotebookLM |
|---|---|---|
Function Calling | No | 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 | Yes | Unknown. Chat streams in the UI, but token streaming is not documented as a product guarantee. |
Fine-Tuning | No | No. You ground on sources. There is no custom-weight training product. |
Embeddings API | No. Gamma's public API generates presentations, documents, websites, and social posts via /v1.0/generations. The documented API options do not include an embeddings or vector-search endpoint. | No. Not an embeddings API. Retrieval stays inside the notebook. |
Structured Output (JSON) | No | Partial. Cloud-computer outputs can include CSV and JSON. Everyday chat is cited prose, not a JSON-schema API. |
Reasoning / Thinking Mode | No | 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. |
