A practical Aider trial
Task: Add a unit-tested CSV validation rule to a small repository.
Check the result: Inspect the Git diff and run the project tests before accepting the change.
Save your starting brief and define a usable result before running the task. Record how many corrections you need and the actual credits or usage consumed. Repeat the same brief in one alternative below; compare the final usable output and your editing time rather than a polished marketing example.
Your Aider trial score
Try the task above before scoring. Give each criterion 0 (not met), 1 (partly met), or 2 (met). Five equally weighted criteria produce your own score out of 100. This is your assessment, not an AI Speed rating or a benchmark.
Score pending: complete all five checks.
Keep a note of your task, plan, model and test date if you compare another tool. These selections stay in this page’s memory and reset when you reload; they are not submitted or stored.
Pricing, availability and Canadian billing
Check the official site for current plans, usage limits, billing currency and Canadian taxes. No fixed price was independently validated.
We do not quote an unverified subscription price. Confirm the displayed currency, applicable Canadian taxes, usage allowances, paid add-ons and cancellation terms with the maker. A public website does not establish that every feature or plan is available to every Canadian account.
