Overview

ConveyThis combines automatic AI or machine translation with human editing tools, including a visual editor and glossary controls. That mix gives teams a way to refine automated output rather than treating translation as a one-time pass. It also handles text in images, buttons, and forms, plus checkout and email localization—useful for ecommerce sites where untranslated interface details can undermine a localized storefront.

Its multilingual SEO features include hreflang, translated metadata, and localized URLs. The breadth is compelling for a website-focused product, though its published plans impose limits on languages, translated words, monthly translation requests, and websites. Teams should compare those allowances with the size and growth of their content before committing.

Key features

Translation and editing: Machine translation is paired with a visual editor and glossary controls, giving marketers or editors room to adjust terminology and presentation.
Website localization: Image text, buttons, forms, checkout, and emails are within scope, extending localization beyond standard page copy.
SEO: Hreflang, translated metadata, and localized URLs address key parts of serving multilingual pages to search engines.
Integrations and import: ConveyThis lists more than 35 platform integrations, including WordPress, Shopify, Wix, Webflow, and Squarespace, and says JavaScript can be used on other sites. CSV and TMX imports are available on every plan, including Free.
Developer access: API access and a read-only MCP server for AI agents are included with the plan. The MCP server is read-only, so it is suited to agent access that does not require writing changes.
Security: The security statement describes SSL 256-bit encryption for browser-to-server data and backups every few hours. Enterprise adds a dedicated GDPR-ready translation server, regional hosting, encryption in transit and at rest, and a commitment not to use customer data to train external LLMs or share it with third parties.

Pricing

ConveyThis is freemium, with monthly paid plans beginning at 12.00 USD per month and a 3-day trial. The allowances below show the main trade-off: lower tiers restrict language count and scale, while higher tiers expand languages, words, and domains. Monthly translation-request allowances are stated for Free and Advanced+; the listed limits should be considered alongside the plan’s other quotas.

Plan	Price	Included allowances
Free	0.00 USD per free	1 language, 5,000 words, 1 domain, 2,500 monthly translation requests
Starter	12.00 USD per month	1 language, 60,000 words, 1 domain
Business	24.00 USD per month	3 languages, 200,000 words, 1 domain
Business+	40.00 USD per month	4 languages, 400,000 words, 1 domain
Pro	64.00 USD per month	5 languages, 800,000 words, 3 domains
Pro+	110.00 USD per month	9 languages, 1,400,000 words, 5 domains
Optimum	160.00 USD per month	14 languages, 2,000,000 words, 10 domains
Corporate	240.00 USD per month	20 languages, 3,000,000 words, 15 domains
Corporate+	320.00 USD per month	30 languages, 4,000,000 words, 20 domains
Advanced	480.00 USD per month	40 languages, 8,000,000 words, 25 domains
Advanced+	640.00 USD per month	80 languages, 6,000,000 words, 30 domains, 3,000,000 monthly translation requests

Free is a bounded way to start, but its 5,000-word allowance, single language, single domain, and 2,500 monthly requests make it a narrow fit for a live site with expanding content. Starter raises the word cap to 60,000 but keeps the one-language, one-domain constraint; it suits a small site that needs more translated content rather than broader reach. Business and Business+ are more practical when a site needs three or four languages. Pro is the first listed tier with more than one domain, making it a better fit for teams translating several sites.

Above Pro, allowances expand for agencies or organizations managing more languages and domains, reaching 80 languages and 30 domains on Advanced+. That final tier lists 6,000,000 words, less than Advanced’s 8,000,000, despite its higher price; buyers should weigh the stated request and domain allowances rather than assume every quota rises with each tier. Support also scales: Free has limited support, Starter through Business+ have basic support, Pro through Corporate have priority support, and larger plans have premium support. There is no stated seat allowance to compare.

Platforms

ConveyThis supports web and API use. Its integration list spans more than 35 platforms, with WordPress, Shopify, Wix, Webflow, and Squarespace among the examples; JavaScript is an option for other websites. The breadth favors teams working with common website platforms, while API access gives developers another integration path.

Who it's for

ConveyThis fits founders, marketers, agencies, and ecommerce teams that need to reach international audiences without a long technical project. Its visual editing, glossary tools, imports, and ecommerce localization make it relevant to teams that want editorial control as well as automated translation. The plan structure is less suitable when a project needs many languages or sites but cannot justify a higher tier.

Pros and cons

Pro: Translation covers more than page text, including interface elements, checkout, and email, which can make localization more consistent across a customer journey.
Pro: CSV and TMX imports are available on Free as well as paid plans, so existing translation material can be brought in without first upgrading.
Pro: The plan ladder gives clear scaling in languages, words, and domains, and higher tiers offer stronger support levels.
Con: Free and Starter support only one language and one domain, limiting their usefulness for teams with broader localization needs.
Con: Monthly translation requests are explicit for Free and Advanced+ but not the intervening plans, making request-volume planning less straightforward.
Con: The general supported-language count is one, while paid plans describe allowances as high as 80 languages; buyers should resolve that distinction before selecting a tier.

Alternatives

For localization work spanning multiple app and desktop platforms, consider Crowdin, which supports Android, iOS, Linux, macOS, Windows, web, and API, and has a free plan.

If the priority is an API translation service with a defined free character allowance, Google Cloud Translation offers 500,000 characters per month free and a Neural Machine Translation text plan at 20.00 USD per month. Lara Translate is another API-capable option, with a free plan providing 60,000 characters per month and one user; it may suit a small individual workflow better than ConveyThis’s website-and-domain structure.

For a browser extension alongside API access, DeepL Translator has a free version with 50,000 characters per user per month, one file translation per month, and one glossary. If a site-focused widget and broad machine-translation language coverage matter more than commercial use, GTranslate has a free widget plan with all languages and unlimited words and pageviews, but no commercial use or search engine indexing.

For string-based software localization, Localizely has a free plan with 250 hosted string keys, one project, unlimited users, and unlimited languages. locize offers a free plan with 100K standard CDN downloads per month, 2,000 words, two languages, five namespaces, and one user; it is worth comparing when those specific delivery and string limits fit better. OneSky is another alternative to assess for localization workflows.

Verdict

ConveyThis is a strong fit for teams translating websites that need more than automated page copy: its editing controls, SEO localization, ecommerce coverage, imports, and integrations support a broad site workflow. Choose it when those capabilities and a fitting domain, word, language, and request tier outweigh the monthly cost. Look elsewhere if the language-count distinction is unresolved for your needs, or if a focused translation API or string-localization workflow is a better match.
