How AI credits work
What converting files and translating documents cost in AI credits, how a run is charged, and how much AI work each task typically takes.
Converting files and translating documents use AI credits, a monthly allowance on every plan. A credit is worth A$0.01. A run uses what its AI work costs us, times four, rounded up to a whole credit. That cost is the tokens the AI model reads and writes, at its maker's price. Tokens are pieces of words: a page of text is a few hundred.
The price follows the work, not the model. When a cheaper model does the same job as well, the same work uses fewer credits.
What a run is charged
- Only a run that works uses credits. One that fails uses none.
- If the AI's first answer has to be fixed and it tries again, the retries are on us.
- Before a run starts, SafetyDocs checks there are enough credits for its estimate, worked out from its length. A PDF counts its pages. A Word file, or a document being translated, counts 250 words a page. The run is then charged what it actually used, which can be a little more or less.
- A conversion takes a file of up to 30 pages. A translation takes a document of up to 60 pages, per language.
What each task typically uses
Measured on our test documents with the models we use today. A page of dense tables uses more than a page of plain text.
| Task | Model | Per | Tokens read | Tokens written | Credits |
|---|---|---|---|---|---|
| Recognising what kind of document a file is | Jev 1.14 (TypeSafe) | file | 740 | 60 | 0.02 |
| Sorting a file's pictures (photos, logos, icons) | Jev 1.14 (TypeSafe) | picture | 730 | 54 | 0.02 |
| Writing a file as a document | Claude Haiku 5.5 (Anthropic) | page | 3,300 | 2,500 | 0.86 |
| Translating a document | DeepSeek v4.1 Flash | page per language | 4,200 | 3,500 | 0.46 |
For example:
- Converting a 6-page PDF with 4 pictures: 0.02 + 4 × 0.02 + 6 × 0.86 = 5.3, so 6 credits.
- Translating a 1,000-word document (4 pages) into Spanish and Chinese: 4 × 0.46 = 1.8 for each language, so 2 credits each, 4 in all.
We update this table when we change a model or add a task.
See and top up your credits
The convert window shows what a file is expected to use while it converts, and what it used once it's done. See what's left this month under Plan and usage. When they run out, buy 1,000 more for A$9.95 under Plan and usage. Credits you buy never expire, and your plan's monthly credits are used first.
