Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Description of Business	1. Organization and description of business Altair Engineering Inc. (“Altair” or the “Company”) is incorporated in the state of Delaware. The Company is a global technology company providing software and cloud solutions in the areas of simulation, high-performance computing (“HPC”), data analytics, and artificial intelligence (“AI”). Altair enables organizations across broad industry segments to compete more effectively in a connected world while creating a more sustainable future. Basis of presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information. Accordingly, the accompanying statements do not include all the information and notes required by GAAP for complete financial statements. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements (and notes thereto) for the year ended December 31, 2020, included in the most recent Annual Report on Form 10-K filed with the SEC. Use of estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its significant estimates including the stand alone selling price, or SSP, for each distinct performance obligation included in customer contracts with multiple performance obligations, valuation of acquired intangible assets in business combinations, the incremental borrowing rate used in the valuation of lease liabilities, the determination of the period of benefit for capitalized costs to obtain a contract, fair value of convertible senior notes, provision for credit loss, tax valuation allowances, liabilities for uncertain tax provisions, impairment of goodwill and intangible assets, retirement obligations, useful lives of intangible assets, revenue for fixed price contracts, and stock-based compensation. Actual results could differ from those estimates. Significant accounting policies There have been no material changes to our significant accounting policies as of and for the nine months ended September 30, 2021, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2020.

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Guidance	2 . Accounting standards adopted Income Taxes – In December 2019, the FASB issued ASU No. 2019-12, , which simplifies the accounting for income taxes by removing certain exceptions to the general principles for income taxes. The Company adopted ASU 2019-12 effective as of January 1, 2021, and the adoption of this guidance did not have a material effect on its consolidated financial statements. Accounting standards not yet adopted Reference Rate Reform – In March 2020, the FASB issued ASU 2020-04. Facilitation of the Effects of Reference Rate Reform on Financial Reporting This ASU provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in the guidance are optional and effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements. Debt – In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for convertible instruments by eliminating certain separation models. Under ASU 2020 - 06 , a convertible debt instrument will generally be reported as a single liability at its amortized cost with no separate accounting for embedded conversion features. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The amendments in this update are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The guidance allows entities to use a modified or full retrospective transition method. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company will adopt ASU 2020-06 on January 1, 2022 , and is currently evaluating the method of adoption and the related effect of the new guidance on its consolidated financial statements and earnings per share attributable to common stockholders.

Fair Value Disclosures [Abstract]
Fair Value Measurements	8 . Fair value measurements The accounting guidance for fair value, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The framework for measuring fair value consists of a three-level valuation hierarchy that prioritizes the inputs to valuation techniques used to measure fair value based upon whether such inputs are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions made by the reporting entity. The three-level hierarchy for the inputs to valuation techniques is briefly summarized as follows: Level 1 – Quoted prices in active markets for identical assets and liabilities at the measurement date; Level 2 – Observable Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. The carrying value of cash and cash equivalents, accounts receivable, net and accounts payable approximate fair value due to their short maturities. Interest on the Company’s line of credit is at a variable rate, and as such the debt obligation outstanding approximates fair value. The carrying value of the Company’s Convertible Notes are at face value less unamortized debt discount and issuance costs. The estimated fair values of the Convertible Notes, which the Company has classified as Level 2 financial instruments, were determined based on quoted bid prices of the Convertible Notes on the last trading day of each reporting period. As of September 30, 2021, the fair value of the Convertible Notes was $356.7 million and is presented for required disclosure purposes only. For further information on the Convertible Notes, see Note 7. – Debt.

The maximum number of shares available for issuance under the ESPP is 3,200,000 shares of the Company’s Class A common stock. The purchase price for each share of common stock purchased under the ESPP will be 85% of the lower of (a) the fair market value per share on the first day of the applicable offering period or (b) the fair market value per share on the applicable purchase date. Each offering period will last a number of months determined by the plan administrator, up to a maximum of 27 months. The initial offering period began on July 15, 2021, and will end on January 14, 2022, and new offering periods are expected to begin on each January 15 and July 15 thereafter, unless modified by the plan administrator. The ESPP allows participants to purchase the Company’s common stock through payroll deductions, up to a maximum of 15% of their eligible compensation or $25,000, whichever is lower, and subject to limitations under Section 423 of the Internal Revenue Code. The plan administrator has limited participant contributions to $1,000 per month to prevent prejudicial advantages to higher compensated employees. Participants may withdraw from the ESPP and receive a refund of their accumulated payroll contributions at any time prior to a purchase date. As of September 30, 2021, $2.1 million has been withheld on behalf of employees for a future purchase under the ESPP due to the timing of payroll deductions. There were no purchases related to the ESPP for the three or nine months ended September 30, 2021.

Segment Reporting [Abstract]
Segment Information	1 4 . Segment information The Company defines its operating segments as components of its business where separate financial information is available and used by the chief operating decision maker (“CODM”) in deciding how to allocate resources to its segments and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has identified two reportable segments for financial reporting purposes: Software and Client Engineering Services.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Basis of presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information. Accordingly, the accompanying statements do not include all the information and notes required by GAAP for complete financial statements. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements (and notes thereto) for the year ended December 31, 2020, included in the most recent Annual Report on Form 10-K filed with the SEC.
Use of Estimates	Use of estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its significant estimates including the stand alone selling price, or SSP, for each distinct performance obligation included in customer contracts with multiple performance obligations, valuation of acquired intangible assets in business combinations, the incremental borrowing rate used in the valuation of lease liabilities, the determination of the period of benefit for capitalized costs to obtain a contract, fair value of convertible senior notes, provision for credit loss, tax valuation allowances, liabilities for uncertain tax provisions, impairment of goodwill and intangible assets, retirement obligations, useful lives of intangible assets, revenue for fixed price contracts, and stock-based compensation. Actual results could differ from those estimates.
Significant Accounting Policies	Significant accounting policies There have been no material changes to our significant accounting policies as of and for the nine months ended September 30, 2021, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2020.
Recent Accounting Guidance	Recent accounting guidance Accounting standards adopted Income Taxes – In December 2019, the FASB issued ASU No. 2019-12, , which simplifies the accounting for income taxes by removing certain exceptions to the general principles for income taxes. The Company adopted ASU 2019-12 effective as of January 1, 2021, and the adoption of this guidance did not have a material effect on its consolidated financial statements. Accounting standards not yet adopted Reference Rate Reform – In March 2020, the FASB issued ASU 2020-04. Facilitation of the Effects of Reference Rate Reform on Financial Reporting This ASU provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in the guidance are optional and effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements. Debt – In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for convertible instruments by eliminating certain separation models. Under ASU 2020 - 06 , a convertible debt instrument will generally be reported as a single liability at its amortized cost with no separate accounting for embedded conversion features. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The amendments in this update are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The guidance allows entities to use a modified or full retrospective transition method. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company will adopt ASU 2020-06 on January 1, 2022 , and is currently evaluating the method of adoption and the related effect of the new guidance on its consolidated financial statements and earnings per share attributable to common stockholders.
