Machine Translation
Free AI translator that runs your text through 22 models and picks the wording most of them agree on.
Consensus is a genuinely useful reliability signal when a mistake is expensive, and SMART turns it into one screen instead of an afternoon of comparison. Tomedes' own contract test, where a multi-model pass surfaced clauses a single engine missed, is the honest case for it. We'd use it on the risky documents and keep a cheaper single-engine tool for the disposable ones.

Skip MachineTranslation.com if you need one fast answer per string at bulk volume, because reading a 22-model comparison grid and paying per credit will cost you more time and money than a single-engine translator.
The free tier only shows a portion of long texts before asking you to pay — the page advertises unlocking full translations for as little as $2.50 per 300 words.
The free tier is genuinely usable for short passages, and the 300-credit pack at $3.75 makes occasional document work cheap — cheaper than a DeepL Pro seat for a single contract. The 5,000-credit pack at $39.50 brings the per-credit rate down for recurring workloads, and Pro is the unlimited option for teams with steady volume. Against per-word agency rates this is inexpensive; against a single-engine API it's a premium you pay for the comparison grid and human review.

About Machine Translation
MachineTranslation.com is a free browser-based AI translator from Tomedes that runs your source text through 22 large language models at once and shows you every version side by side. The model lineup includes ChatGPT, Gemini, Claude, Qwen, Mistral AI, Mercury, Amazon Nova, DeepSeek, Grok, Llama, AI21 and Gemma. Paste text, upload a file or dictate with voice input, and each engine returns its own translation with a quality score and ranking. The differentiator is SMART, a consensus engine that compares all 22 outputs and selects the wording the majority agree on. Tomedes puts the resulting drop in translation error risk at 90%. An accuracy-versus-fluency slider shifts results between faithful and loose, and a translation team panel surfaces the most concise, most natural and closest-to-consensus versions. The AI Translation Agent handles customization: add instructions, upload glossaries or style guides to hold brand voice, and it remembers your edits so the same phrase doesn't get fixed twice. Documents come in PDF, DOCX, CSV, JPG, HTML and HTM with the original layout preserved. The interface is localized into 70+ languages, the site quotes 270+ supported languages (and 330+ elsewhere on the page), and automatic language detection means you don't have to set the source. Human review with ISO-certified accuracy is bookable in-platform, an API covers programmatic access, and the MCP Connector pushes verified translations into Claude and ChatGPT. Privacy terms are stated up front: your content is never used to train AI models, Secure Mode processes sensitive material with zero retention, and the service is described as GDPR compliant with encryption and controlled access. Compared with single-engine tools like DeepL or Google Translate, this is a deliberate read-the-output workflow rather than a one-click convenience.
Behind the Verdict
Pick this when the wording has consequences. A contract, a clinical note, a regulatory filing, a client-facing email in a language you don't read. What you're buying is a disagreement map: 22 engines give you 22 phrasings, and SMART marks the one most of them landed on. Where it bites is speed. Reading a grid of model outputs takes attention a one-click translator never asks for, and if you skip that step you've paid the complexity cost for nothing. The AI Translation Agent is the sleeper feature. Glossaries and style guides plus memory of your past edits mean a terminology-heavy project gets less painful on the second document than the first. We'd set that up on job one, not job five. For mixed formats, document upload keeps the original layout across PDF, DOCX, CSV, JPG and the HTML/HTM support Tomedes added in late September. The one-minute turnaround test they published is a fair frame for what to expect — file in, file out, no layout surgery afterward. Where it passes: bulk product-catalog localization, real-time interpretation, and any pipeline where nobody reads the output. Per-credit packs compound fast at volume, and consensus doesn't help a job nobody supervises. The free tier's fair-use limits will be the first thing heavy users hit. Closest alternative is DeepL or a single frontier model for plain fluency; they're faster and cheaper per word and usually fine. Google Translate still wins on frictionless quick lookups. This sits one tier up, alongside human-review services, for the work where being wrong costs more than being slow. Caveats worth knowing. The site quotes 330+ supported languages in one spot and 270+ in another, so verify your pair before committing. And ten billion words translated says nothing about your specific domain — run a sample

Real-world workflow fit
Concrete scenarios for the personas Machine Translation actually fits — and what changes day-one when you adopt it.
Paste the disputed clause, run it through the 22-model comparison, and read where the models diverge on defined terms before passing the selected version to counterparty counsel.
Outcome: You catch the clause where models split, flag it for a human reviewer, and avoid signing off on a wording that only one engine produced.
Upload the style guide and glossary into the AI Translation Agent, translate the CTA variants, and drag the accuracy-versus-fluency slider toward loose to see which phrasing stays natural.
Outcome: Brand terminology stays consistent across files, the German formal/informal choice is handled automatically, and your edits are remembered for the next batch.
Turn on Secure Mode for zero data retention, translate the note, then route the SMART-selected output to in-platform ISO-certified human review for a second pass.
Outcome: Sensitive content is processed without retention and the final text carries a documented human verification step.
Use Cases
- Translate client-facing business emails and check which AI models agree on the phrasing before sending
- Localize marketing slogans and CTAs by comparing how each model handles tone
- Translate contracts, clinical notes or financial documents where one model's outlier wording is costly
- Give the AI Translation Agent a glossary so regulated terminology stays consistent across documents
- Upload a PDF, DOCX, CSV or JPG and get the translation back with the original layout intact
- Verify critical content with human review for ISO-certified accuracy
- Pull verified translations into Claude or ChatGPT through the MCP Connector
- Translate an HTML or HTM file and get it back with layout intact
Models Under the Hood
as of 2026-10-17
Limitations
- SMART is a consensus signal rather than a correctness guarantee — the vendor's own blog notes that models agreed on a word that means different things by country, so consensus can reproduce a shared error.
- The site reports a 70MB file cap, a 3,000-word text box, and a daily cap on the free tier, with the interface prompting 'Upgrade for best AIs' and 'Go Unlimited', so the strongest models and unlimited use sit behind a paid plan.
- Verified limits come from the blog rather than the pricing page in this evidence, and nothing here establishes that every listed language has a trained model.

Where the pricing makes sense
The company stage and team size where Machine Translation's pricing actually pencils out — and where peers do it cheaper.
The free tier is genuinely usable for short passages, and the 300-credit pack at $3.75 makes occasional document work cheap — cheaper than a DeepL Pro seat for a single contract. The 5,000-credit pack at $39.50 brings the per-credit rate down for recurring workloads, and Pro is the unlimited option for teams with steady volume. Against per-word agency rates this is inexpensive; against a single-engine API it's a premium you pay for the comparison grid and human review.
Setup time & first value
How long it actually takes to get something useful out of Machine Translation — broken out by persona, not the marketing-page minute.
Starting from nothing: under a minute for the free web translator, since no sign-up is required — paste text or upload a file and results appear in seconds. Adding glossaries and style guides to the AI Translation Agent takes a few minutes once you have the terminology list assembled. Wiring the MCP Connector into Claude or ChatGPT is a session task for someone comfortable with developer tooling,
Switching to or from Machine Translation
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Google Translate: paste the same source text here and compare the outputs side by side before trusting either one on a high-stakes document.
- →From DeepL Pro: move your glossary and style guide into the AI Translation Agent so your preferred terminology carries over.
- →From a single ChatGPT prompt: use the MCP Connector to pull verified translations into the ChatGPT workflow you already use.
- →From an agency for routine documents: run the file through the comparison first and reserve paid human review for the passages where models disagree.
- ↗To DeepL: adopt it for high-volume strings where one consistent engine output is faster than reading a comparison grid.
- ↗To a professional translation agency: move contracts and regulated material there when ISO-certified human review is the deliverable, not an add-on.
- ↗To a single LLM API: call one model directly when you want programmatic throughput without the consensus layer.
- ↗To a CAT tool: export your glossary and style guide so a translator can work from the same terminology base.
