**The product.** A service for software teams that ship their app in several languages. When a developer adds new text strings to the code and opens a pull request on GitHub, the Localhero.ai GitHub Action finds the new and changed strings, translates them with an AI model, and commits the translations to the same pull request. A glossary and a style guide keep the terms and the tone the same in every language. Product managers and designers can change a translation in a web page without touching the code, and the change goes back into the pull request.

**Why it worked.** In many teams a finished feature waits days for translations from an agency, or ships in one language first. The founder, a developer for many years, saw this pattern again and again. Localhero.ai moves the translation into the normal code review step, so the feature and all its languages are merged together.

Evidence grades: A = disclosed by a public company, a filing or a payment processor, or verified by one; B = two or more independent reports agree, or a journalist confirmed it; C = a founder claim that no one else verified; D = reported, not verified: one founder claim or a third-party estimate with no second source; E = no revenue figure found, so the headline is a non-money fact and the other facts carry their own grades; calc = computed on this page from graded facts.

## Summary

Localhero.ai is a translation management system (TMS), software that stores an app's text in every language and organizes who translates and reviews it. It works through a GitHub Action, a small program that GitHub runs automatically on each change to a repository. On every pull request (a proposed code change that colleagues review before it is merged) it translates the new text keys in the app's locale files (YAML for Rails, JSON for React, .po files for Django and Phoenix) and commits the result. Arvid Andersson in Stockholm builds it; the company behind it is Andersson-Larsson Holding AB.

The domain showed the product, "AI-powered translations that capture your brand's unique voice", in December 2024, and the command-line tool was first published to npm on 5 December 2024. By May 2025 the pricing page listed paid plans, paid through Polar and Stripe. The first customer was Kundo, a Swedish customer-service platform where the founder also worked as a consultant; it translates into nine languages with Localhero.ai. In his monthly Hacker News posts the founder reported a first fully self-serve customer in spring 2026, a "pretty big Swedish company" in June 2026 and "a few new paying customers" in July 2026.

No revenue figure was found, so this story has grade E. The prices are public: a free plan with 250 credits a month, then US$29, US$79 and US$350 a month, as the pricing page states. The page shows that the product is live and sold, not how much it earns.

## Pricing

Localhero.ai prices in November 2026, from the company's pricing page (grade C)

| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Free (open source or side project) | 0 | 0 | 1 project, 250 credits a month |
| Starter | 24.17 | 29 | 4 team members, 2 projects, 1,250 credits a month |
| Growth | 65.83 | 79 | 8 team members, 5 projects, 3,000 credits a month |
| Professional | 291.67 | 350 | 30 team members, 20 projects, 12,500 credits a month |

One credit translates one key of up to about 100 characters into one language. Every paid plan starts with a 30-day free trial without a card. Yearly billing gives two months free; the monthly equivalents of the yearly prices are calculated. A 500-credit top-up costs US$19 on any paid plan. Enterprise prices are on request.

How to read this table: a grade C value is the company's or the founder's own statement. A grade B value was read on a page that a third party controls (the Internet Archive's dated copies, the npm registry, GitHub Marketplace). A "calc" value was computed on this page. No value is a revenue figure.

## When did Localhero.ai launch, and how did it grow? Timeline

From a one-page site in December 2024 to three paid plans and a GitHub Marketplace app, in 23 months. Each entry carries its grade.

- **December 2024** (grade B [13, 14]): The command-line tool @localheroai/cli is first published to npm (5 December), and localhero.ai shows "AI-powered translations that capture your brand's unique voice".
- **May 2025** (grade B [15]): The pricing page lists a Starter plan at US$29 a month and a Professional plan at US$149 a month, with payments through Polar and Stripe.
- **November 2025** (grade C [8]): The founder describes the product on Hacker News: "Automated i18n translations that run in your CI pipeline."
- **May 2026** (grade C [9]): The founder reports the first fully self-serve customer, who found the product through the documentation.
- **June 2026** (grade C [10, 7]): A new paying customer, "a pretty big Swedish company", and a customer in Japan who asked for Easy Japanese; the Kundo case study is published on 7 June.
- **July to November 2026** (grade C [11, 2, 16]): "A few new paying customers" in July; a GitHub App on the Marketplace, an MCP server and three paid plans at US$29, US$79 and US$350 a month by November.

## Why did Localhero.ai work?

### Translations inside the pull request

The translations are committed to the same pull request that added the strings, so the feature and its translations merge together and the main branch is never half translated. There is no export step and no second pull request.

### Glossary, style guide and memory

Each project has a glossary (terms that must be translated one way, or not at all), a tone setting and a translation memory built from past edits. The founder wrote in March 2026 that edits made by a product manager in the web page now feed back into future translations.

### A surface for people who do not use git

Every pull request gets a page where reviewers see the new strings in every language, change them and approve them; the edits are synced back to the branch as a commit.

## How it was built

These details come from the company's own pages, its llms.txt file and the founder's posts. They are grade C.

- A GitHub Action (localheroai/action), a command-line tool run with npx @localheroai/cli, a GitHub App and a REST API.
- An agent skill for Claude Code and Cursor that gives the coding assistant the project's glossary and tone, and a remote MCP server (Model Context Protocol, a standard that lets AI assistants call outside tools) for Claude.
- Translations run on Microsoft Azure OpenAI inside the EU; glossary, style and quality checks use Anthropic's Claude models through AWS Bedrock in Frankfurt.
- The application and database run on Render in Frankfurt; card payments go through Polar and Stripe.
- Support for Rails YAML, i18next JSON and gettext .po files from Django, Phoenix and LinguiJS, with working example apps on GitHub.

## Who tried this before Localhero.ai, and why did they fail?

Three companies in our database of failed startups promised faster translation or automation inside the developer workflow and failed. The values below are from that database and are not independently verified.

The failed startups come from our database of dead startups, retold here in our own words; Its entries are AI-assisted summaries of public sources, so they carry no evidence grade.

### TurboTranslations (2014 to 2023; funding US$150K; cause: Ran Out of Cash)

- Promise: Faster and cheaper translations through a marketplace of human translators.
- Why it died: It bet on human translators just as machine translation became good enough for most texts.
- Record: 

### Sider (2012 to 2024; funding US$7M; cause: Competition)

- Promise: Automated code review and static analysis for development teams, run in the CI/CD pipeline.
- Why it died: Free open-source tools and large platforms that bundled code analysis took its market.
- Record: 

### Pagedraw (2018 to 2021; funding US$1.5M; cause: Competition)

- Promise: Turn Sketch designs into React code to save developers time.
- Why it died: It bet on Sketch when designers moved to Figma, and developers preferred to write that code themselves.
- Record: 

## What changed

TurboTranslations organized human translators, and machine translation took away its advantage. Localhero.ai starts from the machine translation and sells the work around it: the pull-request step, the glossary, the review page and the memory of past edits.

Sider sold one step in the CI pipeline and was squeezed between free tools and large suites. Localhero.ai faces the same risk, since a team can call a model API from its own script; the founder answers this in his blog post on using the OpenAI API directly and in his March 2026 post: "there is a lot of stuff around it to make it work well over time in a product org."

## Can one person copy Localhero.ai now?

**Verdict: Yes, for a developer who knows one workflow well.**

One founder builds and sells it on rented AI models, with small hosting costs and no outside money. The hard part is not the translation but fitting into the tools a team already uses and earning trust with reference customers.

1. Pick a step that makes finished code wait (translations, screenshots, release notes).
2. Run it where developers already work: a GitHub Action and a command-line tool.
3. Give non-developers a web page to review and edit, synced back to the code.
4. Start with one customer you know, write the case study, then add a free plan for open-source projects.

**What is still open.** The same pattern for other review steps that wait on people: legal copy checks, accessibility text, app-store descriptions in many languages.

## What could go wrong for Localhero.ai?

- **What is not verified.** No revenue figure was found. We looked for a payment-processor profile (TrustMRR, Stripe), a founder post or interview with a dated amount, and a company filing, and found none; Swedish company-data sites block AI agents, so the holding company's accounts were not read. The founder's Hacker News posts mention paying customers without numbers. A reader could look for a revenue statement from the founder or the annual report of Andersson-Larsson Holding AB.
- **The first customer and the founder's consulting.** The Kundo case study says the founder was "also doing some consulting at Kundo" while he built the product, and it is the first customer and the main home-page quote. The home page also shows a second quote and a row of customer logos (Kundo, Willful, Bespoke, Mynewsdesk, OutdoorMap, Qasa); only Kundo has a published case study.
- **Company start date and the founder's other site.** The product launched in December 2024, but the legal seller is a holding company, Andersson-Larsson Holding AB, whose registration date was not checked. The founder also runs infrabase.ai, a directory of AI infrastructure tools, as a side project, as his Hacker News posts say.
- **Competition and model providers.** The site already has Linguana, which translates websites built with Webflow and Framer, and TranslateMom for video; Localhero.ai translates the text inside software and competes more directly with TMS products such as Lokalise, Phrase and Crowdin, which its blog compares. Translations depend on Microsoft Azure OpenAI and checks on Anthropic's Claude through AWS Bedrock, as the security page states; their prices and rules set Localhero.ai's costs.
