Free.ai Rewriter transforms text with broader scope than paraphrasing — 6 modes (Simplify / Elevate / Shorten / Expand / Shift tone / Switch style) and 4 depth levels. Simplify drops reading level to 8th grade with plain vocabulary. Elevate sharpens weak verbs and vague nouns. Switch style translates prose into journalistic / academic / marketing / technical / narrative / legal / poetic register. Shift tone keeps meaning and structure and only changes register (8 tone targets). Word-level diff view highlights every change.
Paraphraser swaps words and sentence structures while preserving tone and length. Rewriter actively transforms — changes reading level (Simplify), upgrades vocabulary (Elevate), compresses (Shorten), inflates (Expand), or translates into a completely different writing style (journalistic vs academic vs marketing). Paraphrase when you want the same idea phrased differently; rewrite when you want the text to do something different.
QuillBot Premium is $9.95/mo with 7 modes and caps free use at 125 words. WordAi is $27/mo. Jasper is $39/mo+. Rytr is $9/mo with 2,000 monthly word cap on the Saver plan. Free.ai runs on self-hosted GPUs, no monthly subscription, 5,000-word runs, and ships purpose-built modes (Elevate, Switch style with 7 registers, 8-tone Shift) instead of one generic rewrite. QuillBot's Ghostwriter IDE integration is genuinely better if you write in Word; Free.ai wins on price, mode variety, and API access.
Translates prose into a target writing style while keeping every fact. Journalistic: AP lead-first, short paragraphs, attribution. Academic: hedge words, Latinate vocabulary, passive voice where conventional. Marketing: benefit-focused ledes, second-person "you", concrete outcomes. Technical: numbered steps, defined terms, imperative verbs. Narrative: scene, sensory detail, POV. Legal: defined terms in caps, precise quantifiers, explicit conditions. Poetic: rhythmic phrasing, figurative density. Use when you need the same content to work in a different genre.
Four known failure modes: (1) Elevate can overcorrect — boring-but-clear prose sometimes gets fancied up past where it works. Use depth 1–2 for Elevate. (2) Expand adds transitions that can read AI-generated — we've tuned the prompt against generic fillers but edit with care. (3) Switch Style → Poetic is the least reliable — poetic prose is voice-heavy and AI can't consistently match a specific poet's voice. (4) Shift Tone → Humorous often skews corny; pair with depth 2 and humor cues from your own input.
Yes — the system prompt hard-requires preserving every fact, number, name, date, and citation. Shorten mode may drop redundant repetition of facts, but any unique claim survives. Expand mode is prompted to never invent new facts. Always verify numbers against the source for high-stakes work (legal, financial, medical).
Same output pipeline, different UX. Tone Changer (/text/tone-changer/) is a single-purpose tool with 10 tone pills — use when tone is your only concern. Rewriter's Shift tone mode is part of a larger workflow — useful when you also want Depth 3 or 4 restructuring alongside the tone shift.
Ten explicit picks: English, Spanish, French, German, Portuguese, Italian, Dutch, Chinese, Japanese, Arabic. Auto-detect works across all 99 Free.ai languages, but rewrite quality is best in English where the mode prompts were developed. For non-Latin scripts (zh/ja/ar), Simplify and Elevate work cleanly; Switch Style → Journalistic/Academic/Marketing also works; Narrative/Poetic are weaker.
Up to 5,000 words (~40,000 characters) per run. For longer documents, rewrite section by section — output quality is highest with under 8K tokens of context. For full-document style shifts, combine with /text/summarizer/ as a preprocessing step.
Text is sent to Free.ai's self-hosted GPUs, processed, and discarded. We do not train on user inputs. We log only timestamp + token cost for billing — never the source text. Generation history (signed-in users) stores a 200-char preview.

Yes. POST to /v1/chat/ with the rewriter system prompt (bearer auth, monthly limits per plan). Useful for CMS style pipelines, email-tone auto-transformers, or multi-register content production. Full snippets at /api/.
