Feature lists look alike across CAT tools, so comparing them on paper rarely helps. What matters is how each feature behaves during real work. This checklist focuses on the capabilities that decide whether your localization team will be fast and consistent, or frustrated and slow.
Translation memory quality
Check how matches are found, shown and edited. Fuzzy matching, context matches and clear difference highlighting save time on every project.
Test with your own past files. Real data shows how well the memory performs.
Glossary integration
Terms should appear in the editor automatically, with warnings when a translator uses a wrong variant. Importing a spreadsheet of terms must be easy.
Look at how the tool treats term variations and forbidden words.
File format support
Teams work with documents, spreadsheets, slides, subtitles, design files and code. A strong cat tool opens all of them and returns files that match the original.
Open a complex file and check the exported layout.
Segmentation control
Sentence splitting rules affect match quality. Good tools let you adjust rules for abbreviations, numbers and special characters.
Wrong segmentation creates poor matches and extra work.
Quality assurance checks
Automatic checks should find missing numbers, tags, double spaces and term errors. Custom rules for your style are a bonus.
Check how easily reviewers can see and filter issues.
Even the best automatic checks have limits, though. They cannot judge whether a translated consent form or patient leaflet actually reads clearly and safely for the people who depend on it. Work like that belongs with certified translation services that serve patients, clinics and pharmaceutical teams under documented quality procedures. Pairing strong in-tool checks with accountable specialists gives regulated content the scrutiny it deserves.
Machine translation options
Look for support for several engines and control over when drafts are used. Memory matches should always rank above drafts.
Test how edits flow back into the memory.
Collaboration features
Several people should be able to work on one project, with roles for translator and reviewer. Comments, locks and live updates avoid confusion.
Try a real hand off from translator to reviewer.
Project management
Managers need to assign files, set deadlines and watch progress. Dashboards and notifications reduce the need for status meetings.
Check how the tool shows overdue items.
Automation and workflows
Rules that move files between steps save manual work. Look for triggers, webhooks and an API.
Even simple automation can save hours each week.
Integrations
Connectors to content platforms, repositories and design tools remove copy and paste. Check which are included and which cost extra.
A broader context is explained in the guide to a translation platform setup.
Editor usability
Translators spend all day here. Check keyboard shortcuts, layout, speed and comfort during long sessions.
Ask translators, not only managers, to judge the screen.
Preview and context
Previews, screenshots and notes reduce guessing. They also catch overflow and layout problems early.
Short strings are risky without context.
Reporting
Word counts, match analysis, productivity and cost reports help with quotes and budgets. Export options matter for finance teams.
Check whether reports are accurate and easy to read.
Security features
Ask about role based access, encryption, audit logs and data location. These matter even more for confidential content.
Review these points with your security team.
Performance
Large files and big memories should open and search quickly. Test with your biggest project, not a small sample.
Slow tools reduce usage and frustrate translators.
Offline and online
Some translators need offline access, others work only in a browser. Check what each mode offers and how sync works.
Sync conflicts are a common source of trouble.
Language and script support
Right to left scripts, East Asian languages and special characters must display and behave correctly.
Test every language you plan to use.
Import and export
Standard exchange formats protect you from lock in. Test exporting your memory and glossary and loading them elsewhere.
Industry bodies such as GALA promote shared standards and best practices.
Training and support
Good documentation, tutorials and fast support shorten onboarding. Ask about trial support and response times.
A short pilot shows how helpful the vendor really is.
Pricing clarity
Understand what is included in each plan and what costs extra. Compare yearly costs for your team size.
Be careful with limits on words, users or storage.
Scalability
Your needs will grow. Check whether you can add users, languages and integrations without changing tools.
Moving a memory later costs time and effort.
Scoring your trial
Rate each feature on a simple scale after the pilot. Share the table with translators, reviewers and managers.
Decide as a team, not by the loudest opinion.
Questions to ask vendors
Ask how updates are delivered, how long old versions are supported and what happens to your data if you leave. Clear answers show whether the vendor plans for long term partnerships.
Request references from teams of a similar size and content type, then ask them what they would change.
Rolling the tool out
Start with one project, move your existing memory, set up a glossary and train a small group. Collect feedback after a month and adjust settings before inviting more users.
Final advice
The best CAT tool is the one your team uses happily every day. Test with real files, check the basics first and add advanced features only when your volume needs them.
