I don't aim to be comprehensive (there are far too many tools available), but just to suggest some starting points.
1. Search and summarize web results
Language model + search results = more current information, less hallucination
Start with these:
Perplexity
Google Gemini
ChatGPT (be sure to click the Search button)
Claude (paid accounts only)
Things to know
Most AI models now can search the web and summarize the results.
They link to the sources so you can easily find the most relevant websites for your search.
ChatGPT free has limited web searches per day.
Claude can only search the web in the paid account (for now).
2. Summarize & ask questions of large documents
Work with documents you upload.
Start with these:
Claude (free or paid) 200,000 tokens
Google Gemini Advanced ($) 1 million tokens. (Gemini offers 2 million tokens for developers in the API).
Others:
ChatGPT free (limited)
ChatGPT Plus
Context windows compared Context window = total input and output of a single conversation.
Things to know
You can upload and work with documents in ChatGPT, but the context window is smaller, so you may need to break your document into smaller chunks if it is very large.
3. Work with up to 50 of your own documents at once
Create study guides, outlines, summaries, FAQ, timeline, and "Audio Overview" from a set of your own documents.
NotebookLM's Audio Overview will generate a "podcast" conversation between two voices, based on your documents.
In Perplexity Spaces, you can search across both uploaded files and web content simultaneously. You can give it specific AI instructions and personas. You can opt out of training in your settings. See A Student's Guide to Using Perplexity Spaces.
4. Analyze your data
Upload a .csv file, summarize the contents, ask questions of it, generate tables and graphs, convert it to HTML/CSS & more.
Start with these: (limited in free accounts, use $ accounts if possible)
Google Gemini
Claude
Others:
ChatGPT
Microsoft Copilot (if logged into work or school account)
Things to know
Free ChatGPT has very limited access to data analysis. You'll run out quickly and have to come back the next day.
Free ChatGPT accounts can use custom GPTs, but not create them. (same with Gemini)
GPTs from OpenAI and bots from Poe allow you to upload specific documents for the GPT to use to answer questions.
All of these chatbots (or GPTs) require the user to sign in to at least a free account to use them.
There are many other tools for creating chatbots based on genAI, and with those you can embed them into your website and not require users to log in to use them.
8. Create public "pages"
A feature of Perplexity that allows you to curate a set of answers with links to sources.
If you are a paying subscriber to Suno, then you own the songs you generate. If you are using a free version of Suno, they retain ownership of the songs you generate, but you're allowed to use those songs for non-commercial purposes.
A good place to get ideas for musical styles for your prompts is in this Wikipedia article: List of music genres and styles.
15. Understand privacy
These AI systems are made up of two parts:
the chat app
the model
The chat app can keep a history of your previous chats.
But the model only knows what's in its training, not everything you've asked in the past.
The chat app can optionally remember your previous chats or save certain facts about you (but only in the app, not for training future models). See Memory FAQ. You can turn this on or off.
"These models don't self-learn. The only time they get better is when the team behind them trains and releases a new version.
Meta AI They train on public posts you've made in Facebook, Instagram, and Whatsapp. They don't train on your private posts or conversations. Opt out here and learn more here.
