“File management became complicated because we were doing it on a Google Drive…So [spf.io’s] file management of the playlist is very helpful. The separation of projects is done naturally…You can just see from the articles, how they are [grouped] in a playlist…As the person is reviewing, you can see a status bar on how many lines that person has already reviewed.”

Tailor the machine translation to your specific domain
Spf.io leverages your translation data to train a custom AI model that imitates your translator’s style and corrections stored in the translation memory. This approach produces nuanced translations for domain-specific content (medicine, theology, politics, economics, etc.) while saving time and effort for your translation team.
1
The user adds translation data for their domain into spf.io.
2
Spf.io trains a custom machine translation model specific to their domain using the translation data.
3
The user can accelerate the content’s translation and reduce the translator’s workload. If desired, they can also contribute the data back to the flywheel for others in the same domain to benefit.

Frequently Asked Questions
What makes spf.io’s Document Translation Portal (DTP) different from Google Translate and other free translation tools?
Spf.io’s Document Translation Portal (DTP) stands out from free translation tools like Google Translate in several key ways:
Context-aware translation
Unlike Google Translate, which often translates text in isolated chunks, DTP uses an AI-powered algorithm to process your documents line by line. By adding a Large Language Model (LLM) integration, you can get context-aware translations based on the previous three lines that have been translated. This approach allows the AI to generate alternative translations that are more consistent with the preceding text and better fit the overall flow and context. You can also utilize custom prompts to refine the instructions given to the AI based on your desired style or output. These custom prompts can be saved and reused within spf.io.
Customizable translations
DTP allows you to review and edit translations. Any changes or corrections you make are added to your autoreplacements database. This means DTP will automatically apply your corrections to the rest of your document and future translations, saving you time and effort. You can also build a glossary to ensure certain words or phrases are never translated or always translated in a specific way.
Domain-specific adaptation
While free tools like Google Translate provide generic translations, DTP adapts to your unique terminology and style. The more you use it, the more it aligns with your specific domain or content, resulting in higher-quality translations.
Efficiency for professional use
DTP is suitable for professionals who need consistent, high-quality translations. Spf.io has a simple interface, which makes it easy for any of your team members to learn how to use it right away. The language filters enable your translators to focus on the content in their language. When post-editing the translation, you can preview the source document to understand the context better. You can work with your team to manage, review, and edit translation documents all in one place. It’s also possible to integrate DTP with your project management platforms like Asana, Airtable, etc.
What languages does spf.io support?
We support over 80 languages for document translation:
|
Albanian |
Galician German Greek Gujarati Haitian Creole Hawaiian Hebrew Hindi Hmong Hungarian Icelandic Indonesian IsiZulu Italian Japanese Javanese Kazakh Khmer Kinyarwanda |
Korean |

How many of my team members can access DTP?
Spf.io is priced on usage levels rather than per user. This means you can invite as many collaborators as you need to post-edit your translation documents.
We built it this way because we believe in community-sourced translation. Many organizations need to make their content available in many languages. To make that affordable, we empower communities with the tools they need to distribute the work among their own staff, volunteers, and members.
Your coordinator or team leader can see an overview of the translation projects and easily track the team’s post-editing progress in the dashboard.
These collaborative features save a lot of time and effort and make delegating work throughout your community a joy rather than a pain.
How do I collaborate with my team members and track their translation progress?
The comment feature allows your editors and translators to leave feedback directly on specific lines in the translation. This eliminates the need to juggle multiple files and emails. Comments can be exported within the Word document, which is helpful for people who prefer to review on paper or are experiencing screen fatigue.
You can organize your documents by adding them to a playlist. In the playlist, you can see the status bar (in blue, yellow, or green) of the post-editing progress for each language assigned to your team members. The green status bar will indicate that the post-editing is done once they select ‘All lines reviewed’ and save the changes in the document editor.
How can I deliver my scripts as captions and translations during a live event?
You simply add your manuscripts, whether pre-translated or translated in spf.io, to a playlist and assign it to your session. Then, during your live event, you can release the translation line by line, ensuring perfect synchronization with your speaker or presentation. This provides a seamless experience for your audience, allowing everyone to follow along in their preferred language.
