10 AI tools that genuinely save developers' time

GitHub Copilot
Code completion directly in the IDE, but not like standard autocomplete: Copilot suggests entire blocks of code, taking your coding style into account. If you are writing a Python script for an API, it can suggest a function with arguments and error handling, rather than just individual lines. It is especially valuable when prototyping new modules or learning a new language.

Price: $10 per month for individual use.

Tabnine
A personal code assistant that learns from your project. The more you work with it, the more accurate its suggestions become. It is particularly useful for large projects with recurring patterns—Tabnine quickly offers ready-made constructs, reducing manual work. For example, auto-generating SQL queries or Java class templates can save several hours a week.

Price: $39 per month for the professional plan.

Replit Ghostwriter
If you frequently prototype ideas or write projects directly in the browser, Ghostwriter will suggest functions, optimize code, and offer options you might not have considered. You can experiment with algorithms or test APIs without installing an IDE. It is perfect for students, hackathons, and quick proofs of concept.

Price: from $100 per month depending on the plan.

Jasper AI
Known as a text generator, this service is useful for IT professionals when creating technical documentation, code comments, automation scripts, or even preparing instructions for a team.

Price: $59 per month.

Runway Gen-2
Not directly related to coding, but an excellent solution for presentations and project demonstrations. The service turns text scripts into videos or animations, which is useful if you need to show a prototype to a client or team. Instead of long editing sessions, you get a ready-made video in just a few minutes.

Price: $12–40 per month, depending on the volume of generation.

Copy.ai
Convenient for creating instructions, internal notes, README files, and documentation. The service helps keep texts structured and clear. It genuinely saves time when a project grows and the amount of documentation starts to outpace code writing. For example, you can quickly create a documentation template for a new module or project.

Price: around $50 per month for the plan.

Notion AI
A tool for structuring notes, creating task plans, and maintaining documentation. Especially useful for teams: you can create technical records, gather project ideas, and immediately turn them into clear tasks. It saves time organizing information that is usually scattered across different places.

Price: ~$10 per month for the AI add-on for Notion.

DeepL Pro
Indispensable for international projects, documentation, or communication with a team from other countries. It translates complex technical texts without losing meaning, saving hours on manual editing. For example, README files or instructions in English for a global project release.

Price: $8.74 per month for the individual plan.

CodiumAI
A service for automated code testing. It analyzes your project and generates tests based on existing functions, saving hours of manual unit test writing. It is especially useful for large Python, JavaScript, and Java projects where maintaining tests usually takes a lot of time. CodiumAI can suggest which test cases you missed and even propose bug fixes.

Price: ~$20 per month.

Ponicode
AI for generating and verifying code tests, as well as auto-completing comments and documentation. It helps quickly create unit tests and maintain code quality as the project grows. If a team is developing a complex module in JavaScript or Python, Ponicode accelerates test coverage and reduces the likelihood of errors.

Price: ~$15–25 per month depending on the plan.
