What should we build?
Agents plan, edit across files, run your tests and iterate until green.
Trusted by 2.4 million developers at fast‑moving teams
Everything you need to stay in flow
A blazing-fast native editor paired with AI that understands your code as well as you do — so you spend your time on decisions, not keystrokes.
Agent
Agents that ship, not just suggest.
Hand off a ticket from Slack, Linear or GitHub. Isotris plans the change, edits across files, runs your tests and opens a PR — in the background, in parallel.
Iso Tab
Predicts your next edit.
Multi-line completions that follow your intent — then jump straight to the next place that needs to change.
Codebase context
Knows your whole repo.
A live semantic index of every file, symbol and dependency. Answers come with citations you can click.
Inline edit
Describe it. Review the diff.
Select code, press ⌘K and say what you want. Every change lands as a clean, reviewable diff.
Models
Every frontier model.
Auto-routes each request to the right model — or pin your favorite and bring your own keys.
Possible race condition
refreshToken() isn't awaited, so concurrent requests can read a stale expiresAt.
Iso Review
A reviewer that reads every line.
Iso Review catches race conditions, auth gaps and logic bugs before your teammates do — and fixes them in one click.
Terminal
Your shell, fluent in English.
Turn intent into commands with ⌘K. Failing builds get diagnosed and fixed in place.
From prompt to pull request
Isotris doesn't just autocomplete. It follows the same loop a great engineer does — and shows its work at every step.
Step 01
Understand
Isotris builds a live semantic map of your repository — symbols, call graphs, docs and git history — and keeps it fresh as you type.

- Respects .gitignore & privacy rules

Step 02
Plan
Before touching code, agents propose a step-by-step plan. You review intent, not a wall of diffs — and edit the plan in plain English.
- Editable, checkpointed plans
- Asks when requirements are fuzzy
- Links every step to the code it touches
Plan· Rate-limit billing endpoints- Add
RateLimiterinterface in packages/billing - Implement sliding-window store on Redis
- Wire limiter into /api/checkout and /api/portal
- Add 429 handling to checkout form
- Cover with unit + integration tests
Step 3 of 5Edit planApprove & continueStep 03
Build
Multi-file edits land as clean, atomic diffs with types and lint checked inline. Run several agents in parallel on isolated worktrees.
- Parallel agents on git worktrees
- Type-aware, lint-clean edits
- Checkpoints you can roll back

Verify
Agents run your test suite, read the failures and fix them in the loop — so you get green builds instead of a to-do list.
- Runs tests, linters and builds
- Self-corrects failing checks
- Iso Review before you ever see it
Verification42 / 42 passing- limiter › allows 10 requests / min
- limiter › blocks the 11th request

The editor people switch for
From solo builders to 5,000-engineer orgs, teams use Isotris to ship more of what matters.
“Isotris is the first AI editor that actually understands our monorepo. The agent opens PRs I'd approve from a senior engineer.”
Maya Okafor
Staff Engineer · Lumora
“Background agents changed my day. I queue up the boring tickets before lunch and review the PRs after.”
Tom Lindqvist
Senior Engineer · Orbital
“Migrated from VS Code in about ninety seconds. Every extension, theme and keybinding came with me.”
Lena Fischer
Frontend Lead · Pyxis
“Plan‑first agents are the killer feature. I review intent before code, which is exactly how it should work.”
Ethan Brooks
CTO · Kitebase
