EmailHelper
EmailHelper is a free, open-source web app that turns a one- or two-sentence brief into a finished business email, in any of 12 languages. No account, no payment, no installation.
What is EmailHelper?
EmailHelper is a single-page web application that writes a business email from a short brief. The page, titled Email Generator, holds a numbered two-step form: a text box asking you to write a few sentences about the email you want, with a placeholder example, then a menu to select your output language, set to English by default. A single button, Generate your email, does the rest. Twelve languages are available: English, Simplified Chinese, Traditional Chinese, Japanese, Italian, German, Spanish, French, Dutch, Korean, Khmer and Hindi. There is no sign-up, no account, no payment and no displayed usage limit. Under the hood, the app builds a prompt from the form, calls OpenAI's GPT-3 API (text-davinci-003) through a Vercel Edge Function and streams the answer back; the announced stack is OpenAI, Next.js, Vercel and Tailwind CSS. This is a personal open-source project rather than a commercial product. Its public template repository carries 718 stars, 173 forks, 70 commits, six open issues and one pull request, and the site was first archived on 28 January 2023. The author, the GitHub user shengxinjing, credits TwitterBio and Danny Richman as inspiration. The app runs on a free vercel.app subdomain, with no legal entity published anywhere.

When to use EmailHelper / When not to
A quick filter to help you decide if EmailHelper is the right fit.
When to use EmailHelper
- Anyone who needs a one-off professional email written fast from a brief of one or two sentences
- People who must write in a language they do not command, thanks to the twelve output languages
- Occasional users who refuse to sign up or hand over a card just to draft a single email
- Developers looking for a working OpenAI and Vercel Edge Functions example: the repository is a public template with a one-click deployment
- Tinkerers who would rather self-host the app with their own OpenAI API key and keep control over where their text goes
When not to use EmailHelper
- Marketing teams running campaigns or sequences: there is no sending, no scheduling and no tracking, only text to copy
- Anyone expecting the tool to plug into a mailbox or a CRM, because no integration exists
- Users who want their drafts kept: with no account there is no history and no saved output
- Organisations handling sensitive or regulated data: no privacy policy, no terms of service and no identified legal entity are published
- Businesses needing a contractual commitment or support: this is a personal open-source project on a free vercel.app subdomain
How to use EmailHelper
A typical end-to-end flow, from setup to results.
- Open the EmailHelper page in any browser: there is nothing to install and no account to create
- Type a few sentences describing the email you want in the first field
- Open the language menu and pick one of the twelve output languages, English being preselected
- Click the generate button; the draft appears progressively as it is streamed back
- Copy the result into your own mail client, since the tool never sends anything itself
- To self-host instead, clone the public repository, create an OpenAI account and put your API key in a .env file
- Run npm run dev to serve the app on localhost:3000, or use the one-click Vercel deployment documented in the README
Pros & Cons
Pros
- Free and immediate: no sign-up, no paywall and no displayed quota
- Twelve output languages, which is a lot for a tool this small
- Two fields and one button, so there is no learning curve at all
- Public, auditable source code, with 718 stars and 173 forks
- Can be self-hosted with your own OpenAI key, which puts the data path back under your control
- Streamed answers, so the draft can be read as it is written
- Contributions are open: the author invites pull requests to add more languages
Cons
- No privacy policy, no terms of service and no legal notice
- No way to reach anyone: no email, no form and no contact page
- No identified legal entity and no published address
- No account, therefore no history and no saved drafts
- No sending and no integration with a mailbox or a CRM
- No tone, length or format setting: the tool does one thing, producing text to copy
- The README names GPT-3 text-davinci-003, an OpenAI model generation dating from January 2023
Pricing & Plans
The hosted application is free of charge. There is no pricing page, no payment mechanism and no account, so nothing can be billed, and no usage limit is displayed; there is neither a paid plan nor a paid trial. The only costs are indirect and concern the self-hosted variant: you supply your own OpenAI API key, which OpenAI bills you for, and you pay for the hosting you deploy to, Vercel being the option documented in the README. The project itself quotes no figure and no currency.

Data, GDPR & hosting
A consolidated view of how EmailHelper handles your data.
GDPR overview
There is no GDPR implementation to report, because there is no mention of it anywhere. Neither the site nor the README refers to the GDPR, to a data protection officer, to a lawful basis for processing or to data subject rights. No EU representative under Article 27 is named. No postal address and no legal entity are published, and an automated scan of the two retrieved pages found no contact email at all, legal or otherwise. No data processing agreement and no subprocessor list are available. Two technical subprocessors can only be inferred from the README: OpenAI, which processes the prompt, and Vercel, which hosts the application and runs the Edge Function. This silence says nothing about how the project actually behaves, but it does mean nothing can be verified.
Who owns the data?
Nothing is published on this point. The site has no terms of service and no privacy policy, and neither the site nor the repository README contains any clause about the ownership of what you type or of the emails the tool returns. There is no user account, so the product exposes no stored content to reclaim in the first place. The only documented fact is technical: the README states that the form input is turned into a prompt, sent to OpenAI's GPT-3 API through a Vercel Edge Function, then streamed back to the page. Ownership of that transiting content is therefore governed by no published commitment from the project itself.
Reuse rights
Here again, no published rule exists. With no terms of service and no privacy policy, the project makes no statement about retention, resale, analysis or model training, and the page mentions no cookie, no tracker and no consent banner. The single documented use is the one described in the README: the form fields are assembled into a prompt, sent to OpenAI's GPT-3 API through a Vercel Edge Function, and the answer is streamed back to the browser. What OpenAI does with that prompt is a matter between you and OpenAI, since this project publishes nothing on the subject. One mitigating point: the source code is public on GitHub, so the data path can be read and audited rather than taken on trust.
Data retention & training
Hosting summary
No hosting information is published. There is no security page, no hosting statement and no region or jurisdiction named, and no certification such as SOC 2 or ISO is mentioned anywhere on the site or in the README. What can be inferred comes from the README and the credits on the home page: the application is deployed on Vercel, and prompts are processed by OpenAI's API. Two network facts were observed, and nothing more. The site's DNS resolves to 216.198.79.3, an address geolocated in the United States (Walnut) and announced by AS16509, Amazon.com Inc. That address is identified as anycast, which means it designates a content delivery network edge node rather than the place where your text is actually processed. In short, the request very probably leaves for the United States, but the project itself commits to nothing regarding jurisdiction, storage location or infrastructure.
Things to keep in mind
Risks and trade-offs to weigh before adopting EmailHelper.
- No privacy policy, no terms of service and no legal notice are published on the site, so nothing frames what happens to your text
- No legal entity, postal address or contact email is published: there is nobody to notify, to question or to hold accountable
- According to the README, what you type is sent to OpenAI's API, and no confidentiality commitment is published to cover that transfer
- Nothing is stated about retention or about training, so keep names, figures and anything confidential out of your brief
- No minimum age is indicated anywhere
- The service runs on a free vercel.app subdomain with no domain of its own, and availability rests on a single author; the share image still points at twitterbio.com, a third-party domain inherited from the project it was inspired by
- Reread before sending: there is no tone, length or format control, and an unchecked generated email goes out in your name, not the tool's
Setup & Integrations
Technical difficulty
Two very different levels. Using the hosted application requires nothing at all: no installation, no account, no configuration and no onboarding, just two fields to fill in and one button to press. Self-hosting is a developer task: clone the repository, create an OpenAI account, put the API key in a .env file and run npm run dev to serve the app on localhost:3000. The README also documents a one-click Vercel deployment, which shortens the path but still assumes an OpenAI key of your own.

Should you pick EmailHelper?
EmailHelper does one thing and does it without friction: describe an email in a couple of sentences, pick one of twelve languages, and copy the draft it streams back. It is free, needs no account and no card, and those twelve output languages make it genuinely useful when you have to write in a language you do not command. The trade-off is everything a product usually brings and this one does not: no privacy policy, no terms, no contact, no identified legal entity, and no availability guarantee on a free vercel.app subdomain. It is a personal open-source project dating from January 2023, and its best answer to that trade-off is the repository itself, which you can self-host with your own OpenAI key if you want control over where your text travels. Fine for occasional, non-sensitive drafting; not a candidate for a company rollout.
