Assumer is an AI coding agent that works inside your client repos, so your team ships more without growing headcount.
Build more, deliver faster, grow your agency
Turn client requirements into reviewed changes in their codebase
Spend less time on boilerplate and fit more client work into each month
Everything Assumer writes lives in the client's repo. No hosted builder, no lock-in.
Open the client's existing repo and Assumer will read the code, explain how it fits together — then plan and make the changes while you review every diff.
read-only analysis before any file is changed
edit files, run commands and tests with your approval
update every file a change touches, not just one
Any stack, from a PHP theme to a Next.js app. Run assumer in the project folder.
Agree on the approach in plan mode, then press Tab to switch to build.
Check the diffs, run the client's tests, then commit and open a PR.
A practical way to take on legacy client work — understand the codebase quickly, propose a plan, and ship through the client's existing pipeline.
The tools to plan, build and deliver client work from the terminal.
A full-tool build agent and a read-only plan agent
Allow, ask or deny per tool and shell command
Connect client databases, trackers and docs
Revert a change with /undo, re-apply with /redo
Point Assumer at an unfamiliar client repo and let the plan agent map its structure, stack and conventions first
Keep each client's conventions in an Assumer.md or existing AGENTS.md so the agent follows their style and tests.
Every edit shows up as a diff. Commit, open a PR for the client's team, and use /undo when a change isn't right.
