In short

What AI contract review actually is

Reviewing a contract with AI means uploading the document into a chat with an AI model, which spends a few minutes pulling out the risky clauses, penalties, deadlines and the other party's unilateral rights, with references to the relevant sections. On the SUIN.AI platform, working through a 15-page contract takes about five minutes and costs roughly 4 neurons — that is 13 rubles; on flagship models of the Claude class, up to 12 neurons, around 36 rubles.

On the free plan you receive 100 neurons when you sign up — enough for around 20 reviews with nothing to pay and no bank card.

Situations you'll recognise

The other side has sent a 30-page contract and it has to be signed tomorrow
The agent reads the whole thing in minutes: it flags penalties, automatic renewal and the other party's unilateral rights — each with a reference to the clause.
A lawyer for every document is expensive, but skipping the review is frightening
The agent handles the routine review and leaves the genuinely contentious points to your lawyer. Reviewing a contract costs about 13 rubles.
Two versions of a contract — what did the other side actually change?
Upload both versions and the agent shows the changes that matter: what happened to the obligations, the deadlines and the amounts.
Reports, statements and tender paperwork are piling up
A context window of up to a million tokens: an annual report fits whole. The agent pulls out the numbers, builds a table and prepares a summary.

How it works

Three steps — nothing to install, no developer needed

Sign up with your email or Yandex ID — no card required. Enter your company website when you register and the platform will build three AI agents matched to your profile, including one for working with documents.
Upload the document straight into the chat — PDF, Word, Excel or a scan: the models read both recognised text and images.
Ask your question in plain words: "find the risks", "compare this with the previous version", "what does this say about payment deadlines". Ask for references to clauses and the agent will quote the document instead of paraphrasing from memory.

For recurring checks, build your own template: upload your policies and price lists into a knowledge base and the agent will check contracts against your own rules. Scenarios for individual lawyers and whole legal departments are on the industry page AI for contracts.

Questions about documents and security

Working through a 15-page contract costs about 4 neurons, roughly 13 rubles; on flagship models of the Claude class, up to 12 neurons, around 36 rubles. On the free plan you receive 100 neurons when you sign up — enough for around 20 reviews.

No, and we don't promise that it will. The agent takes the routine off your hands: it finds the risky passages, collates amounts and deadlines and drafts the questions. The final call on an important contract stays with a person.

PDF, Word, Excel, plain text and images — including scans and photos of documents: the models can read text from pictures.

Your request is processed via API by the provider of the model you choose; the Russian GigaChat and YandexGPT process requests inside Russia. Workspaces are isolated and access is role-based. For sensitive documents we recommend anonymising the data before uploading.

That is fixed by how you phrase the request: require a quote and a clause number for every claim, and allow the answer "this is not in the document". That way the agent checks against the text instead of improvising.
