A linguistic engine for clearer contracts.
It breaks down how contracts are written, highlights what makes them complicated, and helps you rebuild them in clearer, fairer ways. Inspired by plain‑language design and powered by Gemini 3 AI models that understand legal logic.
Drafting support
Rewrites dense clauses into plain English and highlights confusing sections. Side‑by‑side alternatives are delivered in an annotated `.docx` report.
Visual Architect
Turns paragraphs into visuals: timelines, fee tables, responsibility matrices, and flowcharts for conditions.
Key Terms Summary (TLDR)
Persona‑based summaries (Tenant, Supplier, etc.), each backed by a direct quote for instant verification.
Complexity metrics
Measures sentence length, word structure, and language complexity for a clear readability profile.
Clarity & balance check
Flags uneven or unclear language. Not legal advice — a focused signal for review.
Clarity certification

Scores plus explanations.
Classical linguistic formulas plus syntactic analysis — so you know the score and the reason behind it.
Flesch Reading Ease (FKRC)
0–100 scale. Higher scores are easier to read; lower scores indicate complex writing. Uses sentence length and syllables per word.
Gunning Fog Index (GF)
Translates readability into an education level. Legal contracts often score 16–20 (postgraduate difficulty).
Syllable counting logic
Counts vowel groups, ignores silent vowels, and ensures every word counts as at least one syllable.

Syntactic density analysis
Flags passive voice, long sentences (20+ words), and legalese density to pinpoint where clarity can improve.
Interpreting results
Combines scores into a clarity profile so you know what is hard to read and why.
Score ranges
90–100 very easy, 60–70 standard, 30–50 difficult, 0–30 very difficult.

Privacy‑first, practical, and fast.
Processes data locally when possible, includes Redaction Mode, and supports OCR for PDFs or photos. The interface is clean, fast, and available in English, French, and German.
Simplify’s mission is simple: remove the fog from legal writing so you can see what is really said, what could be clearer, and how to create contracts that are readable, responsible, and transparent.
