Wrong contracts. Wrong tone. Zero focus. Data that won't talk. Rewrite Labs builds focused artificial intelligence tools that remove these blockers — one problem at a time. Free to start, every tool.
What is Rewrite Labs?
Rewrite Labs is a suite of free AI SaaS tools built for engineers and builders. Each tool is powered by artificial intelligence — specifically large language models and generative AI — to automate the friction that slows you down: contract review, tone checking, focus tracking, data analysis, and more. Unlike generic SaaS platforms built as software as a service for the broadest audience, every AI SaaS tool here does one job exceptionally well. Artificial intelligence delivered as software as a service means you get the power of a dedicated AI model with zero setup — no API keys, no local models, no configuration. Just open the SaaS tool and use it. Artificial intelligence should reduce friction, not add it. That's the founding principle of Rewrite Labs.
How does the AI work?
Each AI SaaS tool uses natural language processing (NLP) and large language model inference to understand your documents, messages, and data. Generative AI enables human-like analysis without requiring you to prompt-engineer or interpret raw model outputs. These SaaS applications handle all of that — you just get the answer. No data stored, no training on your inputs. Artificial intelligence that actually serves the user rather than harvesting them is the core design principle behind every SaaS tool in Rewrite Labs. Unlike general-purpose AI platforms or bloated SaaS suites, each tool is a narrow artificial intelligence application solving exactly one problem — which is why each SaaS tool performs significantly better than a general-purpose AI assistant on its target task.
You've been here before.
Each of these has cost engineers time, money, or a career opportunity. There's a free tool for every one of them — right here.
The Contract Problem
You sign employment agreements, NDAs, and vendor contracts without understanding half of it — and just hope the risky parts are fine.
→ Solved by Unclause
The Tone Problem
You send a message and immediately think: "that might have landed wrong." It costs you relationships, offers, and opportunities you never even find out you lost.
→ Solved by ToneFix
The Focus Problem
You sit down to build. Three hours pass. You've opened 40 tabs, replied to messages, and shipped nothing. The day is gone and the work isn't done.
→ Solved by FocusVision
The Retention Problem
You read research papers, textbooks, and long docs. An hour later you can barely explain what you read. The knowledge isn't sticking — and you know it.
→ Solved by Lectura.AI
The Data Problem
You have a spreadsheet full of numbers. You know the answer is in there. But turning rows of data into a decision takes longer than making the decision was worth.
→ Solved by DataPulse
The Execution Problem
You have goals, ideas, and real ambition. But your habits, systems, and priorities are scattered — and the gap between what you intend and what you ship keeps widening.
→ Solved by Rewrite OS
The Nutrition Problem
You know you should eat better. But logging every meal in an app feels like a second job, so you quit after two days and go back to guessing.
→ Solved by Sage
The Support Problem
You need someone to talk to — a mentor, a study buddy, someone to vent to. But access is expensive, inconvenient, or just too vulnerable to ask for.
→ Solved by Nura

Built from lived experience
Every tool exists because I hit the problem first. No features built for a pitch deck — just problems, and the cleanest fix possible.
Specific beats general
Generic AI assistants and SaaS tools do everything passably. These artificial intelligence tools do one thing exceptionally. The difference shows the moment you use them on a real problem.
Free first. Always.
Every tool has a real free tier — not a 7-day trial, not a watermarked output. Use it, decide if it earns its place. Pay only when it does.
Your data stays yours
Documents parsed in your browser. Messages never logged. Webcam data never transmitted. The tools work for you — they don't harvest you.
Built by an engineer.
For engineers.
M. Adhitya — builder behind Rewrite Labs, a personal studio (not a company, not a startup). Every tool here exists because I hit the problem first. No VC, no team, no pitch deck — just real friction, removed one tool at a time.
Common questions.
Is the free tier actually free or is it a trial?
Permanently free — not a 7-day trial, not a watermarked output. Use it as long as you want. No credit card required.
Do you store my documents or messages?
No. Documents are parsed in your browser. Messages are never logged. Webcam data is never transmitted. Your data stays yours.
Why not just use ChatGPT for this?
ChatGPT does everything passably. These tools do one thing exceptionally — built for engineers, with the right context, the right output, and real free tiers.
Do the tools work on mobile?
Yes. All tools are browser-based and work on mobile. Webcam-based focus detection works best on desktop.
How much do Pro plans cost?
Individual tools start at ₹199/month. The Rewrite Labs Pro bundle covers all 8 tools at ₹599/month or ₹3,999/year (₹333/month). Pick what works for you.
Who builds and maintains these tools?
M. Adhitya — solo builder behind Rewrite Labs, a personal studio. No VC, no company, no team. Every tool exists because I hit the problem first.
