Why every team writes badly — and the one fix that works.
Most drafts collapse at the second paragraph because the writer hasn't picked a single argument. AresGen's outline-first pass forces the argument out before any prose touches the page.
AI Code
Generate, review, and refactor code with the strongest models — routed per task.
Pair-programming with Claude Opus 4.7 for hard reasoning, GPT-5 Codex for fast iteration, and Gemini Pro for long-context repo reads. Route any prompt to the best model without changing tools or context.

Capabilities
Built for production teams.
Generate from spec
Paste a spec or ticket; receive tested code with type-safe stubs, fixtures, and a passing test suite. Works across frameworks from Next.js routes to Python services.
Review at PR-time
Run a model over any diff and surface bugs, race conditions, security issues, and performance regressions. Each finding ships with a suggested patch you can paste back.
Refactor safely
Type-aware rewrites preserve tests, call sites, and public contracts. Extract helpers, lift state, or migrate patterns without breaking downstream consumers.
1M context
Load entire repositories in a single thread. Walk call graphs, read every test, and reason across hundreds of files without losing fidelity.
Multi-file edits
Coordinated changes across the project tree. Rename a type, update every importer; rewrite an API, patch every caller. Returns a unified diff for review.
40+ languages
TypeScript, Python, Go, Rust, Swift, Kotlin, Java, Scala, Ruby, PHP, C#, and more. Frontend, backend, mobile, systems — one tool covers your stack.
Model routingSee routed model catalog
Pick the right model for the task — no manual switching.
Hard architectural reasoning, large refactors, and code review go to Claude Opus 4.7 for the strongest output. Fast iteration, scaffolding, and short edits route to GPT-5 Codex for speed. Whole-repo reads and dependency tracing route to Gemini Pro for 1M-token context. AresGen makes the routing decision automatically — or you override per prompt.
Auto-route by task profile (reasoning, speed, long-context)
Manual override per prompt or per session
Same conversation context across routed models
Side-by-side model comparison for critical decisions

Repo-aware sessionsBrowse document & file features
Load your whole repo, then ask anything across it.
Drop a repository or folder into the chat and the model indexes every file. Ask about call graphs, walk test coverage, or trace a bug across modules — all in one thread. Folders organize sessions per project, and chat memory carries naming conventions and architectural decisions forward across turns.
Drag-and-drop repository ingestion with .gitignore awareness
Persistent folder structure for per-project sessions
Cross-file reasoning over 1M tokens of source

Use cases
See it in action.
Ship a tested endpoint from a one-paragraph spec.
Prompt
Build a Next.js route handler that validates a Stripe webhook signature, deduplicates by event ID, and queues the job. Return 200 immediately. Include tests.
Sample output
TypeScript route + Zod schema for the payload + idempotency check against the queue + worker stub. Vitest suite covers signature failure, replay, and success — 8/8 tests pass.
Surface real bugs in a 200-line pull request.
Prompt
Review this diff. Flag bugs, race conditions, security issues, and performance regressions. Suggest patches inline.
Sample output
Three findings: race in handleClick on rapid double-tap; N+1 query inside the dashboard loader; missing index on the org_id filter. Each ships with a one-line patch ready to apply.
Lift a rate-limiter into a reusable middleware without breaking callers.
Prompt
Extract the inline rate-limiter into a reusable middleware module. Preserve every existing test and update all four callers.
Sample output
New middleware module under lib/middleware/rate-limit. Four callers updated to the new import. Test suite unchanged — 12/12 tests pass. Diff returned as a unified patch.
Migrate an Express service to Hono with identical behavior.
Prompt
Rewrite this Express route in Hono. Keep request and response behavior identical. Update tests to match the new framework.
Sample output
Hono route with equivalent middleware composition. Test suite ported to Hono testing helpers; assertions unchanged. Diff summary lists every behavioral guarantee preserved across the migration.
Model-defined infrastructure
One workspace.
Every frontier model.
Switch providers mid-thread, A/B test outputs, and route by cost or quality. No re-prompting, no lock-in.

Which model is best for my task — Claude, GPT, or Gemini?
For hard architectural reasoning, large refactors, and code review, Claude Opus 4.7 produces the strongest output. For fast iteration, scaffolding, and short edits, GPT-5 Codex is quicker per token. For whole-repo reads and long dependency traces, Gemini Pro handles the largest context. AresGen auto-routes by task profile, but you can pin a model per prompt or per session.
How does the 1M context window work in practice?
When you drop a repository into the chat, AresGen indexes every file and feeds the relevant slices into the active model. Gemini Pro reads up to 1M tokens directly. Claude and GPT receive smart-retrieved subsets so they can reason across the whole codebase without truncation. You see which files the model used in every reply.
Can I review pull requests without leaving my editor?
Paste any diff — unified, GitHub-format, or raw patch — into the chat and request a review. The model returns findings grouped by severity with suggested patches you can paste back into your editor or directly into the pull request. No browser extension or IDE plugin required.
Will the model remember my project conventions across turns?
Yes. Within a session, chat memory retains naming conventions, type aliases, framework choices, and architectural decisions you have surfaced. Folders persist these memories per project, so returning to the same codebase weeks later picks up where you left off without re-explaining the stack.
