-ChatGPT uses your private conversations history to train its models. [OpenAI disclosed this in this article](https://help.openai.com/en/articles/7730893-data-controls-faq), and if you disable it then you lose all your conversation history!
-* **Use GPT-4 and Claude 3 without two $20 / month subscriptions, you don't even need a single $20 subscription!** You only pay as much as you use. HostedGPT costs nothing so you just pay for your GPT-4 and Claude 3 API usage.
-* **A very polished interface with great mobile support** You can "install" on your mobile phone by opening your instance of HostedGPT in your Safari browser, tapping the Share icon, and then selecting "Add to Home Screen".
-* **You will never hit the '*You've reached the current usage cap*' errors**.

 # Deploy the app on Render
 
 For the easiest way to get started, deploy a full version of HostedGPT to the hosting service, Render, for free. This free app works for 90 days and then the database will stop working. You will need to upgrade to a paid version of the database which is $7 / month. Alternatively, you can also run it off your local computer. Jump down to the [Developer Instructions](#contribute-as-a-developer) if you want to run it locally.
 
 1. Click Fork > Create New Fork at the top of this repository
 2. Create an account on Render.com and login. If you are new to Render, you may be prompted to add a credit card to your account. However, you will be on their free plan by default unless you choose to upgrade.

 # Deploy the app on Fly
 
 Deploying to Fly.io is another great option. It's not quite one-click like Render and it's not 100% free. But we've made the configuration really easy for you and the cost should be about $2 per month, and Render costs $7 per month after 90 days of free servie so Fly is actually less expensive over the long term.
 
 1. Click Fork > Create New Fork at the top of this repository. Pull your forked repository down to your computer (the usual git clone ...).
 1. Install the Fly command-line tool [view instructions](https://fly.io/docs/hands-on/install-flyctl/)

+# Deploy the app on Heroku
+
+Heroku is a one-click option that will cost $10/monnth for the compute (dyno) and database. By default, apps use Eco dynos ($5) if you are subscribed to Eco. Otherwise, it defaults to Basic dynos ($7). The Eco dynos plan is shared across all Eco dynos in your account and is recommended if you plan on deploying many small apps to Heroku. Eco dynos "sleep" after 30 minutes of inactivity and take a few seconds to wake up. Basic dynos do not sleep.
 
+Eligible students can apply for Heroku platform credits through [Heroku for GitHub Students program](https://blog.heroku.com/github-student-developer-program).

+1. Click Fork > Create New Fork at the top of this repository
+1. Sign up for a free Heroku account at [heroku.com](https://signup.heroku.com/)

 # Understanding the Docker configuration
 
 The `Dockerfile` is set up to support three distinct situations: development, deploying to Render, and deploying to Fly. Each of these are completely separate targets which don't share any steps, they are simply in the same Dockerfile.

 The `fly.toml` specifies details of the Fly production environment. It references the `fly-production` build target. The Fly section of the Dockerfile was generated using the dockerfile-rails generator. This is Fly's recommendation and it produces a reasonable production-ready Dockerfile. Edits to this _top section_ of the file have been kept very minimal, on purpose, because it's intended to be updated using the generator. When it was originally generated it saved all the configuration parameters into `config/dockerfile.yml`. When you run `bin/rails generate dockerfile` it will read all these configurations and attempt to re-generate the Dockerfile. You can try this, it will warn you that it's going to overwrite, and press `d` to see the diff of what changes it will make. There should be no functional changes above the line `#### END of FLY ####`. Imagine you wanted to use this generator to change the app to use MySQL ([view all generator options](https://github.com/fly-apps/dockerfile-rails)). You could run `bin/rails generate dockerfile --mysql` and it would update your Gemfile, automatically run bundle install to install any gem changes, and then it will attempt to update Dockerfile where you can again press `d`. Inspect the diff of any changes above the line `#### END of FLY ####` and manually apply those changes. Similarly, view the diff for dockerignore and docker-entrypoint, although none of those changes should be necessary. When you get to `fly.toml` you will want to view that diff closely and manually apply those changes. At the end it will update config/dockerfile.yml to record the new configuration of the Dockerfile. In this way, you can continue to use the generator to keep the Dockerfile updated (as recommended by Fly) while not breaking the dev or Render setup.
