ByteAsk

ByteAsk is an AI coding agent for C and C++ that works from the terminal and verifies its own changes before a developer sees a diff. It edits the repository, builds with the project's own flags and build system, runs the sanitizers and the test suite, and can join a gdb session the developer already has open, then hands back the raw tool output so the reasoning can be audited. It is built for systems programmers working in performance critical or memory sensitive C and C++ codebases. Built in support covers LLVM, GCC and clang, Compiler Explorer, gdb, Valgrind, the address, undefined behavior and thread sanitizers, perf, make, CMake, QuickBench, vcpkg, Conan and Git. Because Linux allows only one debugger per process, ByteAsk joins a live gdb session through a bridge the user starts, reads the stopped state and proposes fixes rather than being locked out. Read only commands run automatically, while anything that changes state is proposed for approval first. Standards and datasheets come from grounded reference corpora returned as excerpts, the full Intel intrinsics dataset is indexed, and the vendor states zero data retention. It installs on Linux, macOS and Windows. Individual pricing is published in US dollars. Free costs $0 and gives full access with your own API keys for 14 days plus about 25 managed agent tasks a month. Pro is $16 per month on an annual subscription ($192 billed up front) or $20 billed monthly, with unlimited use on your own keys and $20 of managed usage each month. Max is $100 per month with five times the managed usage of Pro, and Ultra is $200 per month with ten times. Companies with more than ten people need a Team or Enterprise plan to use their own models. ByteAsk is backed by Y Combinator.
