No description of https://open-gpt.app/ yet.

Erioun is the personal ATS for job seekers — the same system-of-record discipline companies use to track candidates, flipped to work for the candidate instead. The core mechanic: every application you track gets its own dedicated email address (e.g. maria.pavlou.284@apply.erioun.com). When a...

Erioun 5 features
  • Accessible AI Chat Interface
    Provides a user-friendly web-based interface for interacting with GPT-based AI models without needing to set up API access or coding knowledge.
  • No Installation Required
    Being a web application, it can be used directly from a browser without downloading or installing any software.
  • Potentially Free or Low-Cost Access
    Many GPT wrapper sites like this offer free tiers or lower-cost access compared to official API pricing, making AI chat more accessible to casual users.
  • Quick Setup
    Users can typically start chatting almost immediately after visiting the site, with minimal account creation or configuration steps.
  • Cross-Platform Compatibility
    Since it runs in a browser, it can be accessed from various devices including desktops, tablets, and smartphones without platform-specific versions.

Possible disadvantages

  • Uncertain Reliability
    Third-party GPT wrapper websites often depend on underlying API access that can be unstable, rate-limited, or discontinued without notice, affecting consistent availability.
  • Data Privacy Concerns
    Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.
  • Limited Transparency
    It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
  • Potential Hidden Costs or Ads
    Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.
  • Lack of Official Support
    Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.
  • Application Tracker
    See every job you've applied to in one board, with status updates that move automatically as replies come in.
  • Email Hub
    Give every application its own dedicated email address, so replies file themselves under the right job instead of your inbox.
  • CV Vault
    Store every version of your CV in one place and pull up the one that best matches each job you apply to.
  • Fast Apply
    Apply to matched roles in fewer clicks by reusing your saved CV and profile data instead of retyping it each time.
  • Opportunity Radar
    Browse 10,000+ live openings pulled daily from company career sites and job boards, ranked against your profile.

Questions & Answers

As answered by people managing https://open-gpt.app/ and Erioun.

What's the story behind your product?

Erioun's answer:

Erioun came out of watching someone I care about go through a job search that slowly wore them down. Not because they weren't good enough, but because nothing around them was holding the process together. Replies got buried. Interviews got missed because a follow up email disappeared into a crowded inbox. Weeks of effort just quietly leaked away with nothing to show for it, and that feeling of doing everything right and still losing track of your own life was the part that stuck with me.

I built Erioun so that no one else has to carry that weight alone. It gives job seekers the same tracking discipline companies use to manage candidates, except this time it works for the person on the other side of the process. Automatically, quietly, in the background, so the only thing left to focus on is actually landing the job.

What makes your product unique?

Erioun's answer:

Erioun is the only job application tracker where the tracking happens on its own. Every application gets its own dedicated email address, so when a recruiter replies, Erioun reads it, figures out what it means (interview, assessment, offer, rejection), and moves your application forward automatically. You get a one tap Undo if it ever gets something wrong, and nothing is ever sent without your approval.

That same alias system also works as spam protection. Since every application uses its own unique address instead of your real inbox, your personal email never gets exposed to hundreds of job boards and recruiters, and any spam that shows up is easy to trace back to exactly where it leaked from.

Erioun is also built and hosted in the EU, GDPR native from the ground up, so your data is handled under some of the strictest privacy standards that exist rather than bolted on as an afterthought.

Why should a person choose your product over its competitors?

Erioun's answer:

If you're applying to more than a handful of jobs, the real problem isn't finding openings, it's keeping track of what happened after you applied. Recruiters reply days or weeks later, across dozens of threads, and it's on you to remember to update your tracker every single time. Miss one, and you show up unprepared to an interview you forgot you had, or you keep following up on a role that already rejected you.

Erioun fixes that directly. Instead of you updating anything by hand, every application gets its own email address, so replies land, get classified, and move your board forward without you touching it. Huntr, Teal, and Simplify all still expect you to do that tracking yourself. Erioun just does it for you, and adds a CV Fit Score, a daily updated Opportunity Radar with 10,000+ live openings, and GDPR native data handling on top, starting at €2.99/month with a 14 day free trial.

How would you describe the primary audience of your product?

Erioun's answer:

Active job seekers applying to multiple roles at once. Professionals managing a real search across several companies at a time, who want less manual admin and a clearer picture of where each application actually stands, rather than casual browsers applying to one or two jobs.

Which are the primary technologies used for building your product?

Erioun's answer:

Erioun is built with a strong preference for EU based vendors wherever possible, since strict privacy and data protection are core to how the product is run, not an afterthought. Lettermint handles the email infrastructure behind the alias system, OVH is our hosting provider, and PostHog powers our analytics.
