Aimchess is the better fit if you value peer-relative skill scores, opening diagnosis, a weekly plan, and a varied training room. Chessdock is cheaper and better suited to players who want every new Chess.com or Lichess game reviewed automatically, followed by focused engine exploration and a growing spaced puzzle library. Aimchess has the broader coaching plan; Chessdock has the simpler ongoing review loop.
Aimchess and Chessdock start from the same useful idea: your own games should determine what you study. They turn that idea into quite different products. Aimchess looks across a batch of games, diagnoses broader skills, and prepares a weekly plan. Chessdock watches for each new game, surfaces its important mistakes, and feeds them into personal practice.
I build Chessdock. This comparison is written from that perspective, but Aimchess has important capabilities Chessdock does not currently offer. The right choice depends mainly on whether you want diagnosis and planning or a lower-effort stream of fresh reviews.
Choose Aimchess if six-area diagnosis, comparison with similar-rated players, opening weaknesses, and a prescribed weekly training plan are the reason you are shopping for a tool.
Choose Chessdock if you want every new Chess.com or Lichess game reviewed automatically, prefer a concise list of critical positions, and want those mistakes to accumulate as spaced personal puzzles. Chessdock also costs less at the prices compared below.
Aimchess Premium was offered on the web for $7.99 a month or $57.99 a year when checked. Its US iOS prices were higher, so the amount can depend on where you subscribe. Aimchess also has a meaningful free tier with a monthly game report, a weekly plan, and limited daily training.
Chessdock's current US web offer is $5 a month or a limited-time $39 a year, shown against $59. Both paid plans review every new connected game and include puzzles from reviewed mistakes. The plans mainly differ in the amount of older history processed after signup.
That makes Chessdock $2.99 cheaper month to month and $18.99 cheaper on the current annual offers. It is a narrower product, so the lower price is not a claim that it delivers more total functionality. Aimchess charges more for a broader diagnosis-and-curriculum bundle.
Aimchess's current product description says it analyzes recent games in aggregate and compares six areas of your play with people around your rating. It identifies weaknesses, including opening problems, and uses that diagnosis to assemble a weekly study plan.
Its training room is broader than simply replaying blunders. Some exercises draw from the player's games, including Retry Mistakes and positions used in 360 Trainer. Other exercises address skills such as intuition, visualization, advantage conversion, and blunder prevention.
This makes Aimchess the stronger choice when the question is, “What area should I work on this week?” Chessdock does not currently provide peer-relative skill scores, a weekly plan, a dedicated opening trainer, or a surfaced report that groups your history into recurring weaknesses. It can explain and classify individual mistakes without turning them into a diagnosis of your entire game.
Chessdock is organized around a different problem: players often intend to review their games but do not consistently start the analysis. After you connect Chess.com or Lichess, new games are imported and reviewed automatically. The review can be waiting later, together with a mobile notification that it is ready.
Instead of walking through every move, Chessdock presents a shorter list of consequential mistakes from both players. Each position includes severity, winning-chance impact, clock context where available, and direct access to an interactive engine. You can branch into alternatives, compare continuations, or leave the game and explore any position on the standalone analysis board.
The important distinction is frequency rather than breadth. Aimchess periodically turns a body of games into diagnosis and a plan. Chessdock turns each new game into a prepared review and adds its useful positions to an ongoing library.
Aimchess includes personal positions inside a wider set of training exercises. Its product and store descriptions also say difficult tactics can recur later, although the checked material does not describe a durable per-card scheduling system in detail.
Chessdock's personal puzzles come directly from the mistakes selected during review. Failed puzzles, solutions reached with a hint, and imperfect solutions can return after expanding intervals. The selector mixes due repeats with new positions, so a mistake that was not properly corrected has another chance to appear.
This does not make Chessdock's practice automatically better. Aimchess supplies greater variety and connects practice to a weekly plan. Chessdock supplies tighter continuity: the game, mistake explanation, engine exploration, puzzle, and later retry are different views of the same moment.
The cleanest way to compare the products is by the job you want completed.

A player who needs someone to choose the week's training topic is likely to prefer Aimchess. A player who already knows that the main problem is inconsistent review may prefer Chessdock's narrower automation.
Aimchess has not shut down. Its website still offers Premium and its mobile apps remain listed. At the same time, the public iOS and Android releases have not changed since June and July 2024, and users have continued to report a mixture of feature, login, support, and subscription-entitlement problems. Some reported problems were resolved; forum complaints do not measure the experience of every subscriber.
That history is relevant when choosing where to build a long-term training record, but it should not be turned into an abandonment claim. I maintain the detailed evidence, dates, and links separately in Is Aimchess still active?.
If Aimchess works reliably for you and you use its weekly plan, staying is a sensible decision. Chessdock does not reproduce that plan. If you are already looking for a different workflow, the quieter release history makes it reasonable to test an alternative before renewing.
Moving to Chessdock does not transfer completed Aimchess lessons, streaks, training history, skill reports, or study plans. Your original games remain on Chess.com or Lichess and can be processed by another service, but product-specific progress stays behind.
You also give up Aimchess's broader diagnosis and prescribed curriculum. Chessdock replaces the import-review-practice path, not the full Aimchess bundle. For a wider survey of tools that replace different parts of that bundle, see Aimchess alternatives in 2026.
