HelpStack

AI shared inbox for email, chat and social support

Visit

HelpStack is a shared inbox for small teams doing customer support across too many channels. Email, website chat, WhatsApp, Instagram DMs and Facebook Messenger arrive in one place instead of five.

For every conversation the AI drafts a reply and an agent approves or edits it in one click before it is sent. It is not an autonomous bot by default, because fully autonomous support breaks in exactly the cases that matter most.

Auto-translation across more than 40 languages means customers write in their language and agents read in theirs. Hosted in the European Union, GDPR compliant. Free plan with no credit card, paid plans from 29 EUR a month.

Built by a two person team in Ljubljana, inside a working photo business that was selling in four countries and four languages and losing hours a day to five separate inboxes.

I like that replies need a human’s approval before being sent. Having email, WhatsApp, and Instagram in one inbox would also save a lot of switching between tabs. Does the AI learn from the edits agents make to its drafts?

HelpStack looks like a well-designed and thoughtfully built customer support platform. The clean interface, AI-powered assistance, omnichannel inbox, and practical automation features make it a promising solution for businesses looking to streamline support while maintaining a strong customer experience.

Using it so far and its been great!

The one-click approve-before-send model feels like a thoughtful middle ground between manual support and risky full automation. Combining that with Shopify/WooCommerce order context and 40+ language translation could be especially valuable for small international teams. How do agents see the source information behind an AI draft before approving it?

We built this for our own business first. We were selling photos in four countries and four languages, and support was landing in email, Instagram, Facebook, WhatsApp and the website chat. Five places, every day. The part that actually hurt was not the volume, it was not knowing whether someone had already answered. HelpStack puts all of it in one inbox and drafts a reply for every conversation, but it does not send it. An agent approves or edits it in one click. That default is deliberate. Fully autonomous support works right up until the one case where being wrong is expensive, and that is the case customers remember. It is hosted in the EU and GDPR compliant, which started as a requirement for us and turned out to be the first thing a lot of European buyers ask about. Free plan, no credit card. Happy to answer anything, and we are genuinely interested in what breaks for you.

This is a really interesting approach, especially the human approval before anything goes out. We run Vaping Laws and deal with questions from readers around vaping products and educational content, so keeping conversations organized across different channels is definitely something I can relate to. The AI draft + human approval model feels much safer than fully autonomous support. Curious to see how well it handles more niche product-specific questions.

Really happy I’ve found it! as a small business owner, it has freed up so much of my time to focus on creating new products to sell and was super easy to set up

AI drafts, human approves in one click. that's the right default. most support tools force you to choose between full automation or full manual. this nails the middle ground

HelpStack AI has completely transformed our customer support workflow. Managing email, live chat, and social media DMs from a single dashboard has eliminated tab fatigue for our team. The absolute best feature is the AI draft assistant—it creates highly accurate responses instantly, but still leaves our human agents in control to approve or edit before sending. It delivers the perfect mix of speed, safety, and efficiency!

The human-in-the-loop draft-then-approve flow is the right default for support — fully autonomous replies break exactly when tone or policy matters. Curious how you handle WhatsApp/IG thread context when the AI drafts across languages.

The approve-before-send default is the right call. Most AI support tools make full autonomy the headline and bury the human step in settings. Curious how the drafts handle tone across channels, since a WhatsApp reply and an email reply want pretty different registers.

The AI drafts but agent approves before sending is the right default. Most tools go straight to autonomous and that's exactly where it breaks on the cases that matter. Curious how it handles routing when the same customer messages you across two channels at once.

Keeping human approval as the default makes sense, especially for refunds and account issues. The cross-channel threading plus 40+ language translation looks useful for small international teams. How do you surface the Shopify or knowledge-base source behind a drafted answer so an agent can verify it quickly before sending?

The human in the loop approval before sending is a great approach. Saving teams from tab switching across WhatsApp, Instagram, and email while keeping full control is awesome. Congrats on the launch!

Not bad, makes it easier and faster to reply.

The human approval step is probably my favorite part here. AI can handle the repetitive work, while the team still gets the final say on sensitive conversations. Combining that with Shopify/WooCommerce order data and 40+ language translation makes this especially useful for small international teams. Great launch!

Oh, this is interesting!

HelpStack Your product has strong potential, but I found a few key improvements that could make it even better. I'd love to share my feedback and suggestions—please contact me at [email protected].

Love this tool! Super clean and ridiculously helpful.

Love the human-in-the-loop approach, AI drafts plus agent approval feels like the right balance for support.

What caught my attention with HelpStack is how focused it feels on reducing the chaos that comes with managing customer conversations across different channels. Having everything in one place while still keeping the team in control of the responses seems like a sensible balance between automation and a personal touch. Simple idea, but one that could save teams a lot of time as they grow.

Auto-translation in both directions is the tricky part for support: a customer writes in Polish, the agent approves an English draft, and it goes back translated. Which version does the agent actually approve — the English one or the translated output? That's where mistakes usually slip through unnoticed. Also, is there a mobile app or a usable mobile web version? I run everything from a phone, and the approve-before-send flow is exactly the kind of thing I'd want to do while away from a desk

The human-in-the-loop "AI drafts, agent approves" model completely solves the risk of autonomous bots failing on critical support cases. Consolidating email, live chat, and social DMs into one inbox with 40+ language translation is a game-changer for small international teams!

Approve-or-edit before any AI reply goes out is the feature I'd pick this for over fully automated bots — support teams won't accept unreviewed replies reaching customers. The Shopify order-status answers from live tracking data are a strong angle since "where is my order" is most of the queue. How do you handle the case where the crawled knowledge base and the live order data disagree?

Great idea! Seems well thought through :)

This looks like a strong option for smaller e-commerce teams that have outgrown separate inboxes but aren’t ready for the cost and complexity of a large helpdesk platform. The Shopify and WooCommerce integration stands out—the ability to answer order and delivery questions using live data is much more valuable than another chatbot relying on static FAQs. I also like that AI drafts the response while a human remains in control of what gets sent. At €29 a month, the combination of omnichannel support, translation and EU hosting feels very competitive. I’d be interested to know whether fully automated replies can be enabled for low-risk questions and how WhatsApp conversation fees are handled.

The human-in-the-loop default is the strongest part here. AI-drafted replies are useful, but support breaks when teams let automation send low-context answers. I also like the EU-hosted + multilingual angle. Curious how you handle tone consistency when multiple agents edit AI drafts across email, WhatsApp, and social at the same time.

Really like that the AI drafts and a human approves instead of replying autonomously - for support that's the right default, exactly because the edge cases are where it matters. Running an email product (MoeMail, temporary mailboxes) I see the messy side of inbound mail every day, so two questions: how does HelpStack keep a thread together when a customer replies from a different address than they started with, and what happens when a customer writes from a disposable address that has expired by the time your agent replies (bounce handling / flagging)? Also curious whether the OpenAPI import lets an agent tool call back into our own API to look up account state before drafting.

There are already quite a few AI sales agent products out there, but this one really stands out. I especially love the onboarding — it gets users to the “aha” moment incredibly quickly. You can see the product in action right away, without even having to sign up. Really well designed.

Just living, learning, and growing.

This is a really compelling concept. The combination of a unified shared inbox, AI-assisted replies, and human approval feels like the right balance between efficiency and quality—especially for small teams that can’t afford to let important customer conversations fall through the cracks. I particularly like the human-in-the-loop approach. Rather than positioning AI as a replacement for support agents, HelpStack seems designed to remove the repetitive work while keeping people in control of the conversations that actually matter. The multilingual support is another strong differentiator, and the fact that the product was born from your own experience managing customers across multiple countries makes the problem-solution fit feel very authentic. A two-person team building this from a real operational pain point is impressive. HelpStack has the potential to become a very valuable tool for lean, international businesses that want enterprise-level support workflows without enterprise-level complexity. Really interesting product and a thoughtful approach to AI-powered customer support.

Can you customize the processing scenario?
