Smartcat

Smartcat is a translation and localization platform for teams managing multilingual content. Its AI Translator routes content through multiple engines, applies translation memories and glossaries, and can send important work to human reviewers. It supports 280+ languages and 80+ file formats, including documents, images, video, audio, courses, and localization files.

✨ Key Features

• Multi-engine AI translation — Route each language pair and content type through supported translation engines instead of relying on one engine.
• Translation Memory — Reuse approved past translations so repeated text is not translated or charged again in the same way.
• Glossaries and terminology — Apply approved product, legal, and brand terms consistently across jobs.
• Human review workflow — Send selected content to internal reviewers or Marketplace linguists before publication.
• CAT editor and QA — Review translations in the cloud editor and use quality checks for terminology and segments.
• Multiformat localization — Work with 80+ formats, including DOCX, PDF, SRT, SCORM, XLIFF, images, video, and audio.
• AI Coworkers — Use Content Translator, Content Creator, Reviewer, and Content Update Coworkers according to the selected tier.
• Marketplace — Find and manage freelance translators, editors, and proofreaders through the Smartcat Marketplace.
• Team workspaces and integrations — Collaborate in shared workspaces and connect content, design, and developer systems.
• Smartcat API and automation — Automate recurring multilingual workflows using platform integrations and API access on applicable plans.

💳 Pricing

• CAT resources versus AI access — The help center describes free CAT editing, translation memory, glossaries and Marketplace access without a time limit. Its initial AI Smartwords are a one-time allocation that expires after fourteen days. This does not establish perpetual free AI translation or every current product's free eligibility.
• Current AI trial — The main pricing page advertises a fifteen-day trial, including API evaluation. It does not present a recurring free AI Coworkers tier. The help center's fourteen-day initial-credit wording and the main trial belong to different descriptions; confirm the actual product and account offer rather than combining them into a single unconditional promise.
• Adapt — From US$1,200/year, billed annually: 100,000 annual Smartwords and one workspace, with the initial content coworkers and linear workflows.
• Accelerate — From US$24,000/year, billed annually: 1,000,000 annual Smartwords and one workspace, with review and collaboration capabilities.
• Anticipate — From US$60,000/year, billed annually: 2,000,000 annual Smartwords and two workspaces, with content updates and additional workflow controls.
• Autonomous — Custom quote; the comparison lists 6,000,000 annual Smartwords and seven workspaces.
• Human services — Marketplace suppliers set their rates separately.

Smartwords are shared usage credits with consumption rates that vary by task. Translation-memory reuse and manual CAT work must not be confused with unlimited new AI translation. Free CAT resource availability and trial-credit expiry should be confirmed for the selected account.
