Syntag is a translation management system built for tag-heavy CAT work. Import a Trados package, translate with every inline tag held safe, and export a return package that opens clean in Studio.
Request early access No pricing, no card — Syntag is free while we perfect it.Every feature below is tested against real Trados Studio round trips — packages made in Studio, edited in Syntag, and opened again in Studio.
Inline tags render as chips your cursor can't wander into. Pairs live and die together, orphaned halves keep their identity, and a broken tag can't reach export — placeholders block, formatting warns, exactly like Studio.
Import .sdlppx, hand back .sdlrpx. Segments, statuses, formatting, structure context and tracked changes come through intact — verified byte-for-byte against Studio's own output.
Token-aware redlines that respect tags: markup is never split, escaped, or shown as noise. Reviewers see clean insertions and deletions — even inside heavily tagged segments.
Deterministic checks — tags, numbers, whitespace, consistency — never a model's opinion. A project-wide findings panel with a full dismiss-and-restore audit trail keeps sign-off honest.
Bold is bold, headings look like headings, footnotes and hyperlinks announce themselves — or flip one toggle and see every tag as chips. A Basic mode keeps huge files light.
A built-in assistant can pre-translate and draft segment by segment. Drafts are always drafts — every segment waits for a human confirm, and the same tag gates apply to the assistant as to you.
Syntag is in early access, and it is free while we perfect it. Today it speaks SDLXLIFF and Trados packages; file-type support to match Studio is the goal we are building toward, round trip by round trip.
It is built by a working translator who field-tests every build against real Studio projects — the bugs you'd hit are the bugs we hunt. If that sounds like your kind of tool, we'd love your files to break it.
