Unlike Reflo, Doclingo didn't skip any tables; it even translated the footnotes on the financial page. What separates the two tools is how the background is handled, and how steady the type size is.
Doclingo read the text on all four image-only scans and translated nearly all of it: body text, tables, captions and footers. Its approach to the background is to lay a solid-color backing under the translation. On a white or simple background that's barely noticeable. Where the text sits on a photo or old paper, and you want the translation to keep the look of the original, the difference shows.
Reglyph wins this page. Both tools translated all of it and kept the three statistics as large numbers; the difference is the body text over the photo. Doclingo puts a grey band under every line, so the sea shows through a grid of rectangles. Halfway through the third paragraph in the left column there are three rows of grey backing with no text on them before the sentence carries on. The pie chart and the briefcase icon behind the statistics have a few patches too. Ours sets the Chinese directly on the restored photo. Our weak spot is the numbers: bold in the original, thinner in ours.
Reglyph is slightly ahead here, though Doclingo does one thing better: it kept every first-line indent, and we lost ours. The gap is the paper. Each line of Doclingo's English sits on a band of beige close to the color of the page, but the edges of the bands are visible, and the specks and stains of the old paper are gone beneath them. The type size wanders too: the line "free rein to the most absurd fantasies" is a size larger than the one above it. Ours is printed straight onto the original paper, with the engraving and the grain intact.
Doclingo is slightly ahead on this page. On a white page its solid backing is barely visible, all three titles stay on one line, the "Salud intestinal" tab fits, and the footer is in Spanish. On ours the first title wraps onto two lines, the tab label wraps too, and there's a trace of the erased English inside the blue tab. Doclingo's problem is type size: in the first bullet, the line "edad, sexo, altura" is clearly larger than the line above, and in the protein section two bullets are merged into one paragraph. Both have rough spots, but its page is closer to the original.
A tie. Both tools translated the full table, all three footnotes and the chart labels into Japanese, and every number is there. Doclingo has two small issues: in the first row and the total row, the $ that opens the next column ends up after the previous number, so it reads "3,054,791 $"; and some rows are set a size smaller than others. On ours there's a small smudge in the footnotes, and the bold in the header was lost.
Doclingo fitted both papers onto one page with nothing printed over the figures, and it kept first-line indents, which we don't. The problems are in an equation and a few details.
Reglyph wins this page. Doclingo fitted the French onto one page, left the figure clear and indented the paragraphs. But the mass equation in the left column is missing a piece: in the original, π is raised to −8/3 and followed by f to the −11/3; in Doclingo's version the "3 f" is gone, leaving "π^(−8/ −11/3) ḟ". The running head, Physical Review Letters, became "Lettres d'examen physique", roughly "physics exam letters". Several words in the body run together ("lamasse", "trousnoirs"), and one English "the" was left in. Our equation is complete and the journal name is left as it is.
Reglyph has the edge here. Doclingo handled the parameter table well: each row is translated into Korean with the original key in brackets, as in 레이어 수(n_layers), so you can still search the code for it. We kept the keys as written. Both approaches work. We're ahead on two points: the labels under the three diagrams (Vanilla Attention and the others) are translated in ours and left in English in Doclingo's, and Doclingo's body text has a few lines that suddenly drop a size, with very tight line spacing. Our type size stays steady.

Translate 5 pages free, every dayYes. In our test it read all four image-only scans and translated the body text, tables and footers. Where text was printed over a photo or old paper, it laid a solid-color backing under the translation, so the original background behind the text no longer showed.
Mostly. All six pages came back as single pages with columns, tables and figures in place, and first-line indents were kept. The main issue was type size jumping between lines within a paragraph; on one physics paper an equation also lost part of a term.
On scans with busy backgrounds, Reglyph: it restored the photo on the annual-report page where Doclingo laid grey bands, and it was slightly ahead on the 1871 book page. On the colored-panel guide Doclingo was slightly ahead, and the financial table was a tie.
We can't be neutral, so we've tried to make the results checkable: same files and target languages for both, every result shown next to the original, and the things Doclingo did better (like first-line indents, and the colored-panel page) are written up too. All six source pages are public, so you can run them yourself.
