What Is Custom.MT?
Custom.MT is a platform for customising and evaluating machine translation and language model engines, with workflows, quality estimation and post-editing. Custom.MT's pricing path returned a 404, but the real pricing page, last updated January 30, 2026, was linked from the site. It uses a two-layer model of subscription plus translation usage, in euros excluding VAT. Starter is €200 a month with 10 million characters, overage at €20 per million, 10 workflow templates, AI terminology, best engine and basic plugins. Advanced is €1,000 with 30 million characters, €40 overage, 50 templates, Prompt Studio, quality estimation and API access. Compliance is €2,500 with 50 million characters, €50 overage, 100 templates, TMX cleaner, dashboards, a corporate translation portal and VPC or on-prem options. Capacity does not roll over, and service is not interrupted if you exceed it.
The second layer is engine usage billed per provider. You can use Custom.MT's keys, billed at provider cost plus a currency conversion fee, or your own keys at €0 from Custom.MT. Examples per million characters are Microsoft €10, Amazon €15, Google €20, DeepL €30 and ModernMT €50, with language models billed per token across Gemini, Claude and OpenAI models. A start free trial button exists with no length or limits stated. Features include engine comparison by BLEU and WER, automatic post-editing, fine-tuning, MT evaluation, PII anonymisation, and plugins for Trados, Smartling, memoQ and Shopware. No ownership news appeared, and activity signs include 2026 content, though some testimonials look older.
Custom.MT suits localisation teams that want to compare and tune MT engines without building the plumbing. Compare Intento, Smartling and Lilt. Browse the Translation & Language tools directory for more.
