Our AI translation workflow, step by step

Our AI translation workflow, which we call the AI cycle, is built so you can see who did what to your content, and why. It has seven steps and a feedback loop, and each step shows what goes in, what comes out, and who acts: an AI agent, a linguist, or you. If you sign off on how the work gets done, this is the page to check.

It is human-in-the-loop translation with defined roles. Our agents are in-house AI tools that Locstars built on leading AI models, and they run both before and after the linguist. A native linguist works on every job, at the depth your service level sets. A linguist decides every finding, and your instructions outrank everyone.

Every job runs steps 1–4 and 7. Steps 5 and 6 run at the higher service levels, as named in your quote.

Level key used on this page:

  • AI + Check: AI translation with a linguist check
  • AI + Edit: full post-editing by a native linguist, plus a sampled quality check (default)
  • AI + Edit + Review: full post-editing, then a full review by a second linguist

Agents do the volume work, and a linguist makes the call

Each step in the cycle has a named owner: an agent, a linguist, or you, so you always know who decided what. Agents test every file against the rules that can be checked automatically, and the linguist judges the rest and decides what changes.

Illustrative run on sample text. Scripted, not live production.

Then: learn from your reviewers. Every edit your reviewer makes is compared with what we delivered. Each confirmed lesson becomes a glossary entry, a rule or an automatic check before your next batch.

The sample segment

Ihre Bestellung {order_id} wird innerhalb von 2 Werktagen versendet.

Quality gate: passed. Delivered.

What happened, step by step

  1. Client Step 1 Sends the file, the glossary and the style guide.
  2. Agent Step 1 Measures the file and finds what changed since the last batch: one new segment.
  3. Linguist Step 1 Project lead confirms the scope and the service level: AI + Edit + Review.
  4. Agent Step 2 Proposes “Bestellung” for “order”, with its source: your glossary.
  5. Linguist Step 2 Reviewer approves the term.
  6. Agent Step 3 Translates against your glossary, translation memory and rules, then runs automatic checks.
  7. Agent Step 4 Native-reader agent, seeing only the German, flags the word order as reading like a translation.
  8. Linguist Step 4 A native linguist post-edits the segment and fixes the word order.
  9. Agent Step 5 QA agents check accuracy, grammar, style and terminology, each blind to the others’ results.
  10. Linguist Step 5 A second linguist reviews every segment.
  11. Agent Step 6 Advocate and devil’s-advocate agents argue one style finding. The judge agent recommends keeping the edit.
  12. Linguist Step 6 The reviewer decides to keep it and records the reason.
  13. Agent Step 7 Quality gate: not passed. File held. Placeholder {order_id} is missing from the German, so the file does not ship.
  14. Linguist Back to step 4 The linguist restores {order_id}. Nothing else changes.
  15. Agent Step 7 A regression check re-reads the changed text.
  16. Agent Step 7 Quality gate: passed.
  17. Client Step 7 Receives the file, the gate result, the issue log and the quality report.

Every job runs steps 1–4 and 7. Steps 5 and 6 run at the higher service levels, as named in your quote. Step 5 runs at AI + Edit and AI + Edit + Review, and step 6 at AI + Edit + Review.

Compare service levels

Intake and scoping

Step 1 · Runs at: all levels

What goes in: your files in your format (for example, DOCX, XLSX, JSON, or XLIFF), or a job in your translation management system (TMS), plus any references: glossary, translation memory (TM), style guide, and instructions.

  • Agent: measures the files, counts new, matched, and repeated words, finds what changed since the last batch, and lists open questions.
  • Linguist: your project lead confirms the scope and the service level for each content type.
  • You: send files and references, and answer the open questions.

What comes out: a confirmed scope, a service level per content type, and a list of answered questions.

Terminology with sources

Step 2 · Runs at: all levels

What goes in: your glossary, your TM, and the content you have already published.

  • Agent: proposes terms, each with its source. Your own glossary, TM, and published content come first. A form seen once is a candidate, not a rule. At AI + Edit + Review, separate agents research each term independently.
  • Linguist: at AI + Edit and AI + Edit + Review, the reviewer approves new terms and settles any conflict between the researched options. At AI + Check, the checking linguist approves them.
  • You: approve the initial glossary and every new key term (product, feature, and brand names, and legal or regulated terms). Other new terms are approved by your linguist and added to your glossary, which we share whenever you ask.

What comes out: an approved glossary in which every term carries its source.

What you gain: terms your team can trace and defend, used the same way in every batch.

No glossary or style guide yet? We create them with you before production starts.

Calibrated AI translation

Step 3 · Runs at: all levels

What goes in: the source text, the approved glossary, your TM, and your rules.

  • Agent: translates against the glossary, the TM, and your rules, then runs automatic checks on the result.
  • Linguist: no action at this step.
  • You: no action at this step.

What comes out: AI output translated against your terminology and rules, with the automatic checks run and anything they catch flagged for the next step.

Your style rules and instructions go into your own rulebook. We turn the rules that can be tested reliably into automatic checks. Linguists judge meaning, tone, and anything else that needs judgment. Each client’s rules live in that client’s rulebook only.

Native read and linguist edit

Step 4 · Runs at: all levels, at different depths

What goes in: the AI output from step 3.

  • Agent: a native-reader agent sees only the target text and asks one question: does this read like a translation? It flags anything that does. At AI + Check, an accuracy agent also compares source and target and flags meaning risks.
  • Linguist at AI + Check: a native linguist checks every flagged segment plus a random sample, fixes errors, and settles every flag. The linguist’s time goes where the risk is.
  • Linguist at AI + Edit and AI + Edit + Review: a native post-editor edits every segment.

What comes out: a checked translation at AI + Check, or a fully post-edited translation at the higher levels.

What you gain: text that has been read the way your customers will read it, before the linguist works on it.

Independent checks

Step 5 · Runs at: AI + Edit and AI + Edit + Review

What goes in: the post-edited text.

  • Agent: quality assurance (QA) agents check accuracy, grammar, style, and terminology, each blind to the others’ results. Back-translation serves only as a check. It never becomes the target text. At AI + Edit + Review, a red team of agents tries to make the file fail, and it must back every claim with evidence.
  • Linguist at AI + Edit: a reviewer runs a sampled quality check.
  • Linguist at AI + Edit + Review: a second linguist reviews every segment.

What comes out: a list of findings. A finding counts only when it names a concrete defect and points to a reference: the source, your glossary, a rule, or your instructions. Preferences are logged separately and never block delivery.

What you gain: separate checks catch what a single post-editor can miss, and every finding comes with a reason your reviewers can verify.

Debate and decision

Step 6 · Runs at: AI + Edit + Review. At the other levels, the linguist decides findings directly.

What goes in: the findings from step 5.

  • Agent: an advocate agent and a devil’s-advocate agent argue each finding, and a judge agent recommends what to do.
  • Linguist: the reviewer decides each finding and records the reason.
  • You: your instructions outrank everyone.

What comes out: a decision on every finding, with its reason. A script applies the agreed changes.

Quality gate and report

Step 7 · Runs at: all levels

What goes in: the file as it will be delivered.

  • Agent: at AI + Edit + Review, a regression check first re-reads everything that changed. Then an automated quality gate checks the file exactly as it will be delivered. If it fails, the file does not ship.
  • Linguist at AI + Edit + Review: the reviewer does a final read of the file before the gate runs.
  • You: receive the files, the gate result, the issue log, and your updated TM, with a Translation Memory eXchange (TMX) file on request. At AI + Edit and AI + Edit + Review, you also receive glossary changes and a query log, and quality reports: sampled on an agreed schedule at AI + Edit, full with every delivery at AI + Edit + Review.

What comes out: your delivered files and the evidence for them. Every delivery includes the quality-gate result and an issue log. At AI + Edit, sampled quality reports follow the schedule agreed for your program and can cover several small releases; at AI + Edit + Review, each delivery gets a full report.

If the gate flags something that is not an error, we fix the gate’s rule and record the case in your delivery note. We never edit your file just to make it pass.

What you gain: files that do not reach you with broken tags or placeholders, and a record you can show your stakeholders.

Learn from your reviewers

Runs at: all levels

Every edit your reviewer makes is compared with what we delivered. Each confirmed lesson becomes a glossary entry, a rule or an automatic check before your next batch.

  • Agent: compares your reviewer’s edits with our delivery, segment by segment.
  • Linguist: classifies each edit. Confirmed lessons become rules in your rulebook.
  • You: your reviewer’s edits are the input.

When your reviewer’s edit is better than our fix, we say so.

What you gain: once a correction is confirmed, it applies to every later batch, so your reviewers’ rounds get lighter over time.

Who decides

A linguist decides every finding. At AI + Edit + Review, a judge agent recommends first. The order of authority is fixed:

  1. Your instructions and your glossary
  2. The deciding linguist
  3. The judge agent’s recommendation

Decisions you approve stay closed. They reopen only when you ask, or when new evidence appears.

What the agents never do

  • Deliver a job without a linguist. A native linguist works on every job.
  • Decide a finding. A linguist decides, and your instructions outrank the linguist.
  • Edit your file just to pass the gate. If the gate flags something that is not an error, we fix the gate’s rule.
  • Block delivery over a preference. Preferences are logged, not enforced.
  • Reopen a decision you approved, unless you ask or new evidence appears.
  • Apply one client’s rules to another client’s work. Each client’s rules live in that client’s rulebook only.
